What Is a Case Study?

Weighing the pros and cons of this method of research

Verywell / Colleen Tighe

• Pros and Cons

What Types of Case Studies Are Out There?

Where do you find data for a case study, how do i write a psychology case study.

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in many different fields, including psychology, medicine, education, anthropology, political science, and social work.

The point of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.

While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, we got you—here are some rules of APA format to reference.  

At a Glance

A case study, or an in-depth study of a person, group, or event, can be a useful research tool when used wisely. In many cases, case studies are best used in situations where it would be difficult or impossible for you to conduct an experiment. They are helpful for looking at unique situations and allow researchers to gather a lot of˜ information about a specific individual or group of people. However, it's important to be cautious of any bias we draw from them as they are highly subjective.

What Are the Benefits and Limitations of Case Studies?

A case study can have its strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.

One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult or impossible to replicate in a lab. Some other benefits of a case study:

• Allows researchers to capture information on the 'how,' 'what,' and 'why,' of something that's implemented
• Gives researchers the chance to collect information on why one strategy might be chosen over another
• Permits researchers to develop hypotheses that can be explored in experimental research

On the other hand, a case study can have some drawbacks:

• It cannot necessarily be generalized to the larger population
• Cannot demonstrate cause and effect
• It may not be scientifically rigorous
• It can lead to bias

Researchers may choose to perform a case study if they want to explore a unique or recently discovered phenomenon. Through their insights, researchers develop additional ideas and study questions that might be explored in future studies.

It's important to remember that the insights from case studies cannot be used to determine cause-and-effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.

Case Study Examples

There have been a number of notable case studies in the history of psychology. Much of  Freud's work and theories were developed through individual case studies. Some great examples of case studies in psychology include:

• Anna O : Anna O. was a pseudonym of a woman named Bertha Pappenheim, a patient of a physician named Josef Breuer. While she was never a patient of Freud's, Freud and Breuer discussed her case extensively. The woman was experiencing symptoms of a condition that was then known as hysteria and found that talking about her problems helped relieve her symptoms. Her case played an important part in the development of talk therapy as an approach to mental health treatment.
• Phineas Gage : Phineas Gage was a railroad employee who experienced a terrible accident in which an explosion sent a metal rod through his skull, damaging important portions of his brain. Gage recovered from his accident but was left with serious changes in both personality and behavior.
• Genie : Genie was a young girl subjected to horrific abuse and isolation. The case study of Genie allowed researchers to study whether language learning was possible, even after missing critical periods for language development. Her case also served as an example of how scientific research may interfere with treatment and lead to further abuse of vulnerable individuals.

Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie's case, her horrific abuse denied her the opportunity to learn a language at critical points in her development.

This is clearly not something researchers could ethically replicate, but conducting a case study on Genie allowed researchers to study phenomena that are otherwise impossible to reproduce.

There are a few different types of case studies that psychologists and other researchers might use:

• Collective case studies : These involve studying a group of individuals. Researchers might study a group of people in a certain setting or look at an entire community. For example, psychologists might explore how access to resources in a community has affected the collective mental well-being of those who live there.
• Descriptive case studies : These involve starting with a descriptive theory. The subjects are then observed, and the information gathered is compared to the pre-existing theory.
• Explanatory case studies : These   are often used to do causal investigations. In other words, researchers are interested in looking at factors that may have caused certain things to occur.
• Exploratory case studies : These are sometimes used as a prelude to further, more in-depth research. This allows researchers to gather more information before developing their research questions and hypotheses .
• Instrumental case studies : These occur when the individual or group allows researchers to understand more than what is initially obvious to observers.
• Intrinsic case studies : This type of case study is when the researcher has a personal interest in the case. Jean Piaget's observations of his own children are good examples of how an intrinsic case study can contribute to the development of a psychological theory.

The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.

The type of case study that psychology researchers use depends on the unique characteristics of the situation and the case itself.

There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:

• Archival records : Census records, survey records, and name lists are examples of archival records.
• Direct observation : This strategy involves observing the subject, often in a natural setting . While an individual observer is sometimes used, it is more common to utilize a group of observers.
• Documents : Letters, newspaper articles, administrative records, etc., are the types of documents often used as sources.
• Interviews : Interviews are one of the most important methods for gathering information in case studies. An interview can involve structured survey questions or more open-ended questions.
• Participant observation : When the researcher serves as a participant in events and observes the actions and outcomes, it is called participant observation.
• Physical artifacts : Tools, objects, instruments, and other artifacts are often observed during a direct observation of the subject.

If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines you need to follow. If you are writing your case study for a professional publication, check with the publisher for their specific guidelines for submitting a case study.

Here is a general outline of what should be included in a case study.

Section 1: A Case History

This section will have the following structure and content:

Background information : The first section of your paper will present your client's background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.

Description of the presenting problem : In the next section of your case study, you will describe the problem or symptoms that the client presented with.

Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.

Your diagnosis : Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client's symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.

Section 2: Treatment Plan

This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.

• Cognitive behavioral approach : Explain how a cognitive behavioral therapist would approach treatment. Offer background information on cognitive behavioral therapy and describe the treatment sessions, client response, and outcome of this type of treatment. Make note of any difficulties or successes encountered by your client during treatment.
• Humanistic approach : Describe a humanistic approach that could be used to treat your client, such as client-centered therapy . Provide information on the type of treatment you chose, the client's reaction to the treatment, and the end result of this approach. Explain why the treatment was successful or unsuccessful.
• Psychoanalytic approach : Describe how a psychoanalytic therapist would view the client's problem. Provide some background on the psychoanalytic approach and cite relevant references. Explain how psychoanalytic therapy would be used to treat the client, how the client would respond to therapy, and the effectiveness of this treatment approach.
• Pharmacological approach : If treatment primarily involves the use of medications, explain which medications were used and why. Provide background on the effectiveness of these medications and how monotherapy may compare with an approach that combines medications with therapy or other treatments.

This section of a case study should also include information about the treatment goals, process, and outcomes.

When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research. 

In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?

Need More Tips?

Here are a few additional pointers to keep in mind when formatting your case study:

• Never refer to the subject of your case study as "the client." Instead, use their name or a pseudonym.
• Read examples of case studies to gain an idea about the style and format.
• Remember to use APA format when citing references .

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

What Is a Case Study? | Definition, Examples & Methods

Published on May 8, 2019 by Shona McCombes . Revised on November 20, 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyze the case, other interesting articles.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism. Run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

TipIf your research is more practical in nature and aims to simultaneously investigate an issue as you solve it, consider conducting action research instead.

Unlike quantitative or experimental research , a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

Example of an outlying case studyIn the 1960s the town of Roseto, Pennsylvania was discovered to have extremely low rates of heart disease compared to the US average. It became an important case study for understanding previously neglected causes of heart disease.

However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.

Example of a representative case studyIn the 1920s, two sociologists used Muncie, Indiana as a case study of a typical American city that supposedly exemplified the changing culture of the US at the time.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews , observations , and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.

Example of a mixed methods case studyFor a case study of a wind farm development in a rural area, you could collect quantitative data on employment rates and business revenue, collect qualitative data on local people’s perceptions and experiences, and analyze local and national media coverage of the development.

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis , with separate sections or chapters for the methods , results and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

What Is a Case Study in Psychology?

Categories Research Methods

A case study is a research method used in psychology to investigate a particular individual, group, or situation in depth . It involves a detailed analysis of the subject, gathering information from various sources such as interviews, observations, and documents.

In a case study, researchers aim to understand the complexities and nuances of the subject under investigation. They explore the individual’s thoughts, feelings, behaviors, and experiences to gain insights into specific psychological phenomena. 

This type of research can provide great detail regarding a particular case, allowing researchers to examine rare or unique situations that may not be easily replicated in a laboratory setting. They offer a holistic view of the subject, considering various factors influencing their behavior or mental processes. 

By examining individual cases, researchers can generate hypotheses, develop theories, and contribute to the existing body of knowledge in psychology. Case studies are often utilized in clinical psychology, where they can provide valuable insights into the diagnosis, treatment, and outcomes of specific psychological disorders. 

Case studies offer a comprehensive and in-depth understanding of complex psychological phenomena, providing researchers with valuable information to inform theory, practice, and future research.

Examples of Case Studies in Psychology

Case studies in psychology provide real-life examples that illustrate psychological concepts and theories. They offer a detailed analysis of specific individuals, groups, or situations, allowing researchers to understand psychological phenomena better. Here are a few examples of case studies in psychology: 

Phineas Gage

This famous case study explores the effects of a traumatic brain injury on personality and behavior. A railroad construction worker, Phineas Gage survived a severe brain injury that dramatically changed his personality.

This case study helped researchers understand the role of the frontal lobe in personality and social behavior. 

Little Albert

Conducted by behaviorist John B. Watson, the Little Albert case study aimed to demonstrate classical conditioning. In this study, a young boy named Albert was conditioned to fear a white rat by pairing it with a loud noise.

This case study provided insights into the process of fear conditioning and the impact of early experiences on behavior. 

Genie’s case study focused on a girl who experienced extreme social isolation and deprivation during her childhood. This study shed light on the critical period for language development and the effects of severe neglect on cognitive and social functioning. 

These case studies highlight the value of in-depth analysis and provide researchers with valuable insights into various psychological phenomena. By examining specific cases, psychologists can uncover unique aspects of human behavior and contribute to the field’s knowledge and understanding.

Types of Case Studies in Psychology

Psychology case studies come in various forms, each serving a specific purpose in research and analysis. Understanding the different types of case studies can help researchers choose the most appropriate approach. 

Descriptive Case Studies

These studies aim to describe a particular individual, group, or situation. Researchers use descriptive case studies to explore and document specific characteristics, behaviors, or experiences.

For example, a descriptive case study may examine the life and experiences of a person with a rare psychological disorder. 

Exploratory Case Studies

Exploratory case studies are conducted when there is limited existing knowledge or understanding of a particular phenomenon. Researchers use these studies to gather preliminary information and generate hypotheses for further investigation.

Exploratory case studies often involve in-depth interviews, observations, and analysis of existing data. 

Explanatory Case Studies

These studies aim to explain the causal relationship between variables or events. Researchers use these studies to understand why certain outcomes occur and to identify the underlying mechanisms or processes.

Explanatory case studies often involve comparing multiple cases to identify common patterns or factors. 

Instrumental Case Studies

Instrumental case studies focus on using a particular case to gain insights into a broader issue or theory. Researchers select cases that are representative or critical in understanding the phenomenon of interest.

Instrumental case studies help researchers develop or refine theories and contribute to the general knowledge in the field. 

By utilizing different types of case studies, psychologists can explore various aspects of human behavior and gain a deeper understanding of psychological phenomena. Each type of case study offers unique advantages and contributes to the overall body of knowledge in psychology.

How to Collect Data for a Case Study

There are a variety of ways that researchers gather the data they need for a case study. Some sources include:

• Directly observing the subject
• Collecting information from archival records
• Conducting interviews
• Examining artifacts related to the subject
• Examining documents that provide information about the subject

The way that this information is collected depends on the nature of the study itself

Prospective Research

In a prospective study, researchers observe the individual or group in question. These observations typically occur over a period of time and may be used to track the progress or progression of a phenomenon or treatment.

Retrospective Research

A retrospective case study involves looking back on a phenomenon. Researchers typically look at the outcome and then gather data to help them understand how the individual or group reached that point.

Benefits of a Case Study

Case studies offer several benefits in the field of psychology. They provide researchers with a unique opportunity to delve deep into specific individuals, groups, or situations, allowing for a comprehensive understanding of complex phenomena.

Case studies offer valuable insights that can inform theory development and practical applications by examining real-life examples. 

Complex Data

One of the key benefits of case studies is their ability to provide complex and detailed data. Researchers can gather in-depth information through various methods such as interviews, observations, and analysis of existing records.

This depth of data allows for a thorough exploration of the factors influencing behavior and the underlying mechanisms at play. 

Unique Data

Additionally, case studies allow researchers to study rare or unique cases that may not be easily replicated in experimental settings. This enables the examination of phenomena that are difficult to study through other psychology research methods . 

By focusing on specific cases, researchers can uncover patterns, identify causal relationships, and generate hypotheses for further investigation.

General Knowledge

Case studies can also contribute to the general knowledge of psychology by providing real-world examples that can be used to support or challenge existing theories. They offer a bridge between theory and practice, allowing researchers to apply theoretical concepts to real-life situations and vice versa. 

Case studies offer a range of benefits in psychology, including providing rich and detailed data, studying unique cases, and contributing to theory development. These benefits make case studies valuable in understanding human behavior and psychological phenomena.

Limitations of a Case Study

While case studies offer numerous benefits in the field of psychology, they also have certain limitations that researchers need to consider. Understanding these limitations is crucial for interpreting the findings and generalizing the results. 

Lack of Generalizability

One limitation of case studies is the issue of generalizability. Since case studies focus on specific individuals, groups, and situations, applying the findings to a larger population can be challenging. The unique characteristics and circumstances of the case may not be representative of the broader population, making it difficult to draw universal conclusions. 

Researcher bias is another possible limitation. The researcher’s subjective interpretation and personal beliefs can influence the data collection, analysis, and interpretation process. This bias can affect the objectivity and reliability of the findings, raising questions about the study’s validity. 

Case studies are often time-consuming and resource-intensive. They require extensive data collection, analysis, and interpretation, which can be lengthy. This can limit the number of cases that can be studied and may result in a smaller sample size, reducing the study’s statistical power. 

Case studies are retrospective in nature, relying on past events and experiences. This reliance on memory and self-reporting can introduce recall bias and inaccuracies in the data. Participants may forget or misinterpret certain details, leading to incomplete or unreliable information.

Despite these limitations, case studies remain a valuable research tool in psychology. By acknowledging and addressing these limitations, researchers can enhance the validity and reliability of their findings, contributing to a more comprehensive understanding of human behavior and psychological phenomena. 

While case studies have limitations, they remain valuable when researchers acknowledge and address these concerns, leading to more reliable and valid findings in psychology.

Case studies

Case studies are essential to qualitative research , offering a lens through which researchers can investigate complex phenomena within their real-life contexts. This chapter explores the concept, purpose, applications, examples, and types of case studies and provides guidance on how to conduct case study research effectively.

Whereas quantitative methods look at phenomena at scale, case study research looks at a concept or phenomenon in considerable detail. While analyzing a single case can help understand one perspective regarding the object of research inquiry, analyzing multiple cases can help obtain a more holistic sense of the topic or issue. Let's provide a basic definition of a case study, then explore its characteristics and role in the qualitative research process.

Definition of a case study

A case study in qualitative research is a strategy of inquiry that involves an in-depth investigation of a phenomenon within its real-world context. It provides researchers with the opportunity to acquire an in-depth understanding of intricate details that might not be as apparent or accessible through other methods of research. The specific case or cases being studied can be a single person, group, or organization – demarcating what constitutes a relevant case worth studying depends on the researcher and their research question .

Among qualitative research methods , a case study relies on multiple sources of evidence, such as documents, artifacts, interviews , or observations , to present a complete and nuanced understanding of the phenomenon under investigation. The objective is to illuminate the readers' understanding of the phenomenon beyond its abstract statistical or theoretical explanations.

Characteristics of case studies

Case studies typically possess a number of distinct characteristics that set them apart from other research methods. These characteristics include a focus on holistic description and explanation, flexibility in the design and data collection methods, reliance on multiple sources of evidence, and emphasis on the context in which the phenomenon occurs.

Furthermore, case studies can often involve a longitudinal examination of the case, meaning they study the case over a period of time. These characteristics allow case studies to yield comprehensive, in-depth, and richly contextualized insights about the phenomenon of interest.

The role of case studies in research

Case studies hold a unique position in the broader landscape of research methods aimed at theory development. They are instrumental when the primary research interest is to gain an intensive, detailed understanding of a phenomenon in its real-life context.

In addition, case studies can serve different purposes within research - they can be used for exploratory, descriptive, or explanatory purposes, depending on the research question and objectives. This flexibility and depth make case studies a valuable tool in the toolkit of qualitative researchers.

Remember, a well-conducted case study can offer a rich, insightful contribution to both academic and practical knowledge through theory development or theory verification, thus enhancing our understanding of complex phenomena in their real-world contexts.

What is the purpose of a case study?

Case study research aims for a more comprehensive understanding of phenomena, requiring various research methods to gather information for qualitative analysis . Ultimately, a case study can allow the researcher to gain insight into a particular object of inquiry and develop a theoretical framework relevant to the research inquiry.

Why use case studies in qualitative research?

Using case studies as a research strategy depends mainly on the nature of the research question and the researcher's access to the data.

Conducting case study research provides a level of detail and contextual richness that other research methods might not offer. They are beneficial when there's a need to understand complex social phenomena within their natural contexts.

The explanatory, exploratory, and descriptive roles of case studies

Case studies can take on various roles depending on the research objectives. They can be exploratory when the research aims to discover new phenomena or define new research questions; they are descriptive when the objective is to depict a phenomenon within its context in a detailed manner; and they can be explanatory if the goal is to understand specific relationships within the studied context. Thus, the versatility of case studies allows researchers to approach their topic from different angles, offering multiple ways to uncover and interpret the data .

The impact of case studies on knowledge development

Case studies play a significant role in knowledge development across various disciplines. Analysis of cases provides an avenue for researchers to explore phenomena within their context based on the collected data.

This can result in the production of rich, practical insights that can be instrumental in both theory-building and practice. Case studies allow researchers to delve into the intricacies and complexities of real-life situations, uncovering insights that might otherwise remain hidden.

Types of case studies

In qualitative research , a case study is not a one-size-fits-all approach. Depending on the nature of the research question and the specific objectives of the study, researchers might choose to use different types of case studies. These types differ in their focus, methodology, and the level of detail they provide about the phenomenon under investigation.

Understanding these types is crucial for selecting the most appropriate approach for your research project and effectively achieving your research goals. Let's briefly look at the main types of case studies.

Exploratory case studies

Exploratory case studies are typically conducted to develop a theory or framework around an understudied phenomenon. They can also serve as a precursor to a larger-scale research project. Exploratory case studies are useful when a researcher wants to identify the key issues or questions which can spur more extensive study or be used to develop propositions for further research. These case studies are characterized by flexibility, allowing researchers to explore various aspects of a phenomenon as they emerge, which can also form the foundation for subsequent studies.

Descriptive case studies

Descriptive case studies aim to provide a complete and accurate representation of a phenomenon or event within its context. These case studies are often based on an established theoretical framework, which guides how data is collected and analyzed. The researcher is concerned with describing the phenomenon in detail, as it occurs naturally, without trying to influence or manipulate it.

Explanatory case studies

Explanatory case studies are focused on explanation - they seek to clarify how or why certain phenomena occur. Often used in complex, real-life situations, they can be particularly valuable in clarifying causal relationships among concepts and understanding the interplay between different factors within a specific context.

Intrinsic, instrumental, and collective case studies

These three categories of case studies focus on the nature and purpose of the study. An intrinsic case study is conducted when a researcher has an inherent interest in the case itself. Instrumental case studies are employed when the case is used to provide insight into a particular issue or phenomenon. A collective case study, on the other hand, involves studying multiple cases simultaneously to investigate some general phenomena.

Each type of case study serves a different purpose and has its own strengths and challenges. The selection of the type should be guided by the research question and objectives, as well as the context and constraints of the research.

The flexibility, depth, and contextual richness offered by case studies make this approach an excellent research method for various fields of study. They enable researchers to investigate real-world phenomena within their specific contexts, capturing nuances that other research methods might miss. Across numerous fields, case studies provide valuable insights into complex issues.

Critical information systems research

Case studies provide a detailed understanding of the role and impact of information systems in different contexts. They offer a platform to explore how information systems are designed, implemented, and used and how they interact with various social, economic, and political factors. Case studies in this field often focus on examining the intricate relationship between technology, organizational processes, and user behavior, helping to uncover insights that can inform better system design and implementation.

Health research

Health research is another field where case studies are highly valuable. They offer a way to explore patient experiences, healthcare delivery processes, and the impact of various interventions in a real-world context.

Case studies can provide a deep understanding of a patient's journey, giving insights into the intricacies of disease progression, treatment effects, and the psychosocial aspects of health and illness.

Understanding the key elements of case study design is crucial for conducting rigorous and impactful case study research. A well-structured design guides the researcher through the process, ensuring that the study is methodologically sound and its findings are reliable and valid. The main elements of case study design include the research question , propositions, units of analysis, and the logic linking the data to the propositions.

The research question is the foundation of any research study. A good research question guides the direction of the study and informs the selection of the case, the methods of collecting data, and the analysis techniques. A well-formulated research question in case study research is typically clear, focused, and complex enough to merit further detailed examination of the relevant case(s).

Propositions

Propositions, though not necessary in every case study, provide a direction by stating what we might expect to find in the data collected. They guide how data is collected and analyzed by helping researchers focus on specific aspects of the case. They are particularly important in explanatory case studies, which seek to understand the relationships among concepts within the studied phenomenon.

Units of analysis

The unit of analysis refers to the case, or the main entity or entities that are being analyzed in the study. In case study research, the unit of analysis can be an individual, a group, an organization, a decision, an event, or even a time period. It's crucial to clearly define the unit of analysis, as it shapes the qualitative data analysis process by allowing the researcher to analyze a particular case and synthesize analysis across multiple case studies to draw conclusions.

Argumentation

This refers to the inferential model that allows researchers to draw conclusions from the data. The researcher needs to ensure that there is a clear link between the data, the propositions (if any), and the conclusions drawn. This argumentation is what enables the researcher to make valid and credible inferences about the phenomenon under study.

Understanding and carefully considering these elements in the design phase of a case study can significantly enhance the quality of the research. It can help ensure that the study is methodologically sound and its findings contribute meaningful insights about the case.

Considering recently published examples can help understand how to select and define cases effectively.

Developing a detailed case study protocol

A case study protocol outlines the procedures and general rules to be followed during the case study. This includes the data collection methods to be used, the sources of data, and the procedures for analysis. Having a detailed case study protocol ensures consistency and reliability in the study.

The protocol should also consider how to work with the people involved in the research context to grant the research team access to collecting data. As mentioned in previous sections of this guide, establishing rapport is an essential component of qualitative research as it shapes the overall potential for collecting and analyzing data.

Collecting data

Gathering data in case study research often involves multiple sources of evidence, including documents, archival records, interviews, observations, and physical artifacts. This allows for a comprehensive understanding of the case. The process for gathering data should be systematic and carefully documented to ensure the reliability and validity of the study.

Analyzing and interpreting data

The next step is analyzing the data. This involves organizing the data , categorizing it into themes or patterns , and interpreting these patterns to answer the research question. The analysis might also involve comparing the findings with prior research or theoretical propositions.

Writing the case study report

The final step is writing the case study report . This should provide a detailed description of the case, the data, the analysis process, and the findings. The report should be clear, organized, and carefully written to ensure that the reader can understand the case and the conclusions drawn from it.

Each of these steps is crucial in ensuring that the case study research is rigorous, reliable, and provides valuable insights about the case.

The type, depth, and quality of data in your study can significantly influence the validity and utility of the study. In case study research, data is usually collected from multiple sources to provide a comprehensive and nuanced understanding of the case. This section will outline the various methods of collecting data used in case study research and discuss considerations for ensuring the quality of the data.

Interviews are a common method of gathering data in case study research. They can provide rich, in-depth data about the perspectives, experiences, and interpretations of the individuals involved in the case. Interviews can be structured , semi-structured , or unstructured , depending on the research question and the degree of flexibility needed.

Observations

Observations involve the researcher observing the case in its natural setting, providing first-hand information about the case and its context. Observations can provide data that might not be revealed in interviews or documents, such as non-verbal cues or contextual information.

Documents and artifacts

Documents and archival records provide a valuable source of data in case study research. They can include reports, letters, memos, meeting minutes, email correspondence, and various public and private documents related to the case.

These records can provide historical context, corroborate evidence from other sources, and offer insights into the case that might not be apparent from interviews or observations.

Physical artifacts refer to any physical evidence related to the case, such as tools, products, or physical environments. These artifacts can provide tangible insights into the case, complementing the data gathered from other sources.

Ensuring the quality of data collection

Determining the quality of data in case study research requires careful planning and execution. It's crucial to ensure that the data is reliable, accurate, and relevant to the research question.

However, a systematic and rigorous approach to analysis can ensure that the findings are credible and meaningful. This section outlines the main steps and considerations in analyzing data in case study research.

Organizing the data

The first step in the analysis is organizing the data. This involves sorting the data into manageable sections, often according to the data source or the theme. This step can also involve transcribing interviews, digitizing physical artifacts, or organizing observational data.

Categorizing and coding the data

Once the data is organized, the next step is to categorize or code the data. This involves identifying common themes, patterns, or concepts in the data and assigning codes to relevant data segments. Coding can be done manually or with the help of software tools, and in either case, qualitative analysis software can greatly facilitate the entire coding process. Coding helps to reduce the data to a set of themes or categories that can be more easily analyzed.

Identifying patterns and themes

After coding the data, the researcher looks for patterns or themes in the coded data. This involves comparing and contrasting the codes and looking for relationships or patterns among them. The identified patterns and themes should help answer the research question.

Interpreting the data

Once patterns and themes have been identified, the next step is to interpret these findings. This involves explaining what the patterns or themes mean in the context of the research question and the case. This interpretation should be grounded in the data, but it can also involve drawing on theoretical concepts or prior research.

Verification of the data

The last step in the analysis is verification. This involves checking the accuracy and consistency of the analysis process and confirming that the findings are supported by the data. This can involve re-checking the original data, checking the consistency of codes, or seeking feedback from research participants or peers.

Like any research method , case study research has its strengths and limitations. Researchers must be aware of these, as they can influence the design, conduct, and interpretation of the study.

Case Study: Psychology Definition, History & Examples

In the realm of psychology, the case study method stands as a profound research strategy, employed to investigate the complexities of individual or group behaviors, disorders, and treatments within real-life contexts.

With its roots tracing back to the early 20th century, the case study has evolved from the foundational works of pioneers like Sigmund Freud and Jean Piaget, who meticulously documented individual cases to extract broader psychological principles.

Through intensive qualitative analysis of a single case or a small group, psychologists gain rich, contextualized insights that quantitative methods may overlook. Illustrative examples range from Freud’s study of Anna O. to contemporary explorations into cognitive development.

This introduction sets the stage for a detailed exploration of the case study’s application within psychology, its historical significance, and the exemplary instances that have shaped our understanding of the human mind.

Table of Contents

A case study in psychology is a detailed investigation of an individual, group, event, or community to understand their thoughts, behaviors, and development. It helps psychologists gain in-depth insights and generate hypotheses by examining specific characteristics and experiences.

Case studies provide a unique perspective and contribute to broader theories and generalizations about the human mind.

The historical background of psychological case studies dates back to the early 19th century, originating primarily in Europe and North America. Key figures in the development of this approach include Sigmund Freud, Carl Jung, and Ivan Pavlov.

Sigmund Freud, an Austrian physician and neurologist , is widely regarded as one of the most influential figures in the history of psychology. His work on psychoanalysis, which heavily relied on case studies, revolutionized the field. Freud’s theories emphasized the role of the unconscious mind and the importance of childhood experiences in shaping adult behavior . His famous case study of ‘Anna O.’ provided valuable insights into the treatment of hysteria and laid the foundation for future explorations of the unconscious.

Another significant contributor to the development of case studies was Carl Jung, a Swiss psychiatrist and psychoanalyst. Jung’s theories expanded upon Freud’s ideas and introduced concepts such as the collective unconscious and archetypes. His case study of ‘The Red Book,’ in which he documented his own psychological experiences and self-analysis, offered a unique perspective on the exploration of the human psyche.

In the field of behaviorism , Ivan Pavlov, a Russian physiologist, conducted influential studies on classical conditioning . Although Pavlov’s work primarily focused on animal subjects, his findings paved the way for the application of case studies in understanding human behavior. By examining individual cases and their responses to conditioned stimuli, psychologists were able to gain insights into learning processes and behavior modification techniques.

Throughout the history of psychology, various significant events and studies contributed to the evolution of case studies. One notable example is the ‘Little Albert’ experiment , conducted by John B. Watson and Rosalie Rayner in 1920. This case study demonstrated the principles of classical conditioning by conditioning a young boy to fear a white rat through associating it with a loud noise. The study provided valuable insights into the effects of conditioning on emotions and paved the way for further research in behaviorism.

• Jane is a college student who experiences extreme anxiety before exams. She notices that her heart races, she has difficulty breathing, and she feels a sense of dread. This is an example of the term ‘panic attack’ in a real-life context. Understanding this term helps Jane and others like her recognize and manage their anxiety symptoms.
• Mark is a father who often finds himself losing his temper with his children. He notices that he becomes easily frustrated, yells, and sometimes even becomes physically aggressive. This is an example of the term ‘anger management’ in a real-life context. Learning about anger management techniques can help Mark develop healthier ways to cope with his emotions and improve his relationship with his children.
• Sarah is a teenager who constantly compares herself to others on social media. She notices that this comparison leads to feelings of low self-esteem , sadness, and a negative body image. This is an example of the term ‘social comparison’ in a real-life context. Understanding social comparison can help Sarah recognize the negative impact it has on her well-being and take steps to cultivate a more positive self-perception.
• John is a middle-aged man who recently lost his job. He feels a deep sense of hopelessness, has difficulty sleeping, and has lost interest in activities he used to enjoy. This is an example of the term ‘depression’ in a real-life context. Recognizing the signs of depression can help John seek appropriate support and treatment to improve his mental health and overall well-being.
• Emily is a young woman who experiences intense fear and avoidance when confronted with small spaces. She notices that her heart races, she feels dizzy, and she has difficulty breathing in confined areas. This is an example of the term ‘claustrophobia’ in a real-life context. Understanding claustrophobia can help Emily identify triggers and develop coping strategies to manage her fear and live a more fulfilling life.

Related Terms

Understanding related terminology is essential for comprehensively grasping the concepts exemplified in the aforementioned case studies of psychological phenomena. Terminologies such as ‘control group,’ which refers to subjects not exposed to experimental treatment, and ‘variable,’ denoting aspects that can be altered and measured, are fundamental in the design and interpretation of psychological research. Additionally, the terms ‘independent variable’ and ‘dependent variable’ are closely linked to the concept of a variable . The independent variable is the factor manipulated by the researcher, while the dependent variable is the outcome or response being measured. These terms work together to establish cause-and-effect relationships in experiments.

Furthermore, ‘quantitative’ and ‘qualitative’ analysis represent differing approaches to data—numeric and narrative, respectively. Quantitative analysis involves the use of statistical methods to analyze numerical data, while qualitative analysis focuses on understanding subjective experiences and meanings through non-numerical data such as interviews, observations, or textual analysis. These two approaches complement each other, as quantitative analysis provides statistical rigor and generalizability, while qualitative analysis offers rich contextual insights.

Empathy arises when considering ‘subjective well-being,’ a term that underscores the personal nature of psychological assessment. Subjective well-being refers to an individual’s self-reported evaluation of their own happiness and life satisfaction. Empathy, on the other hand, refers to the ability to understand and share the feelings of others. While subjective well-being focuses on the individual’s own assessment of their psychological state, empathy involves relating to and understanding the emotions of others. These terms are interconnected as they both relate to the emotional experiences of individuals, but they differ in the focus of assessment.

The methodical examination of terms like ‘reliability’ and ‘validity’ is crucial, as they define the consistency and accuracy of research findings. Reliability refers to the consistency or stability of measurements, indicating the extent to which the results can be replicated. Validity, on the other hand, refers to the accuracy or truthfulness of the conclusions drawn from the research. While reliability ensures consistency, validity ensures that the study measures what it intends to measure and draws appropriate conclusions. These terms are interrelated, as a study must be reliable to be valid, but a study can be reliable without being valid. Therefore, both reliability and validity are essential considerations in ensuring the quality of research findings.

Each of these terms interlocks to form a comprehensive understanding of psychological case studies, facilitating a nuanced discourse in the field. By understanding the relationships between these related terms, researchers and practitioners can effectively design and interpret psychological research, analyze data, assess subjective experiences, and evaluate the quality of their findings.

• Case studies are particularly useful for exploring rare or unique phenomena, generating hypotheses for future research, and understanding the complexities of human behavior and experiences.
• The findings from case studies are typically not generalizable to larger populations, but they can provide valuable insights and inform the development of new theories or the refinement of existing ones.
• Case studies are an important research method in psychology, as they allow researchers to study complex human behaviors, mental processes, and social interactions in depth.

Review Questions

• Case studies provide a detailed, in-depth examination of specific individuals, groups, or situations, allowing researchers to explore the complexities of human behavior and mental processes in real-world contexts. By collecting a wide range of data, including interviews, observations, and documents, case studies enable researchers to gain a comprehensive understanding of the unique characteristics and experiences of the subject, which can lead to the development of new hypotheses and the refinement of existing theories in psychology.
• The primary advantage of case studies is that they allow for a deep, nuanced understanding of complex phenomena that may not be easily captured through other research methods. Case studies can provide valuable insights into rare or unique situations, generate hypotheses for future research, and contribute to the development of new theories. However, the findings from case studies are typically not generalizable to larger populations, and the subjective nature of the data collection and analysis can introduce potential biases. Additionally, case studies can be time-consuming and resource-intensive, making them less suitable for large-scale studies. Nonetheless, case studies remain an important research method in psychology, particularly for exploring the complexities of human behavior and mental processes.
• Case studies play a crucial role in the scientific method and theory development in psychology. By providing in-depth, contextual examinations of specific individuals, groups, or situations, case studies can generate new hypotheses and insights that can inform the development of theories. The rich, qualitative data collected through case studies can help researchers identify previously overlooked variables, refine existing theories, and explore the boundaries of current understanding. While the findings from case studies may not be directly generalizable, they can contribute to the overall body of knowledge in psychology and guide the design of future, larger-scale studies. In this way, case studies serve as an important complement to other research methods, helping to advance the scientific understanding of human behavior and mental processes.

Descriptive Research and Case Studies

Learning objectives.

• Explain the importance and uses of descriptive research, especially case studies, in studying abnormal behavior

Types of Research Methods

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it. Some methods rely on observational techniques. Other approaches involve interactions between the researcher and the individuals who are being studied—ranging from a series of simple questions; to extensive, in-depth interviews; to well-controlled experiments.

The three main categories of psychological research are descriptive, correlational, and experimental research. Research studies that do not test specific relationships between variables are called descriptive, or qualitative, studies . These studies are used to describe general or specific behaviors and attributes that are observed and measured. In the early stages of research, it might be difficult to form a hypothesis, especially when there is not any existing literature in the area. In these situations designing an experiment would be premature, as the question of interest is not yet clearly defined as a hypothesis. Often a researcher will begin with a non-experimental approach, such as a descriptive study, to gather more information about the topic before designing an experiment or correlational study to address a specific hypothesis. Descriptive research is distinct from correlational research , in which psychologists formally test whether a relationship exists between two or more variables. Experimental research goes a step further beyond descriptive and correlational research and randomly assigns people to different conditions, using hypothesis testing to make inferences about how these conditions affect behavior. It aims to determine if one variable directly impacts and causes another. Correlational and experimental research both typically use hypothesis testing, whereas descriptive research does not.

Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. For example, studies that rely primarily on observation produce incredible amounts of information, but the ability to apply this information to the larger population is somewhat limited because of small sample sizes. Survey research, on the other hand, allows researchers to easily collect data from relatively large samples. While surveys allow results to be generalized to the larger population more easily, the information that can be collected on any given survey is somewhat limited and subject to problems associated with any type of self-reported data. Some researchers conduct archival research by using existing records. While existing records can be a fairly inexpensive way to collect data that can provide insight into a number of research questions, researchers using this approach have no control on how or what kind of data was collected.

Correlational research can find a relationship between two variables, but the only way a researcher can claim that the relationship between the variables is cause and effect is to perform an experiment. In experimental research, which will be discussed later, there is a tremendous amount of control over variables of interest. While performing an experiment is a powerful approach, experiments are often conducted in very artificial settings, which calls into question the validity of experimental findings with regard to how they would apply in real-world settings. In addition, many of the questions that psychologists would like to answer cannot be pursued through experimental research because of ethical concerns.

The three main types of descriptive studies are case studies, naturalistic observation, and surveys.

Clinical or Case Studies

Psychologists can use a detailed description of one person or a small group based on careful observation.  Case studies  are intensive studies of individuals and have commonly been seen as a fruitful way to come up with hypotheses and generate theories. Case studies add descriptive richness. Case studies are also useful for formulating concepts, which are an important aspect of theory construction. Through fine-grained knowledge and description, case studies can fully specify the causal mechanisms in a way that may be harder in a large study.

Sigmund Freud   developed  many theories from case studies (Anna O., Little Hans, Wolf Man, Dora, etc.). F or example, he conducted a case study of a man, nicknamed “Rat Man,”  in which he claimed that this patient had been cured by psychoanalysis.  T he nickname derives from the fact that among the patient’s many compulsions, he had an obsession with nightmarish fantasies about rats. 

Today, more commonly, case studies reflect an up-close, in-depth, and detailed examination of an individual’s course of treatment. Case studies typically include a complete history of the subject’s background and response to treatment. From the particular client’s experience in therapy, the therapist’s goal is to provide information that may help other therapists who treat similar clients.

Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion. Like other research methodologies within psychology, the case study must produce valid and reliable results in order to be useful for the development of future research. Distinct advantages and disadvantages are associated with the case study in psychology.

A commonly described limit of case studies is that they do not lend themselves to generalizability . The other issue is that the case study is subject to the bias of the researcher in terms of how the case is written, and that cases are chosen because they are consistent with the researcher’s preconceived notions, resulting in biased research. Another common problem in case study research is that of reconciling conflicting interpretations of the same case history.

Despite these limitations, there are advantages to using case studies. One major advantage of the case study in psychology is the potential for the development of novel hypotheses of the  cause of abnormal behavior   for later testing. Second, the case study can provide detailed descriptions of specific and rare cases and help us study unusual conditions that occur too infrequently to study with large sample sizes. The major disadvantage is that case studies cannot be used to determine causation, as is the case in experimental research, where the factors or variables hypothesized to play a causal role are manipulated or controlled by the researcher.

Naturalistic Observation

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances are that almost everyone in the classroom will raise their hand, but do you think hand washing after every trip to the restroom is really that universal?

This is very similar to the phenomenon mentioned earlier in this module: many individuals do not feel comfortable answering a question honestly. But if we are committed to finding out the facts about handwashing, we have other options available to us.

Suppose we send a researcher to a school playground to observe how aggressive or socially anxious children interact with peers. Will our observer blend into the playground environment by wearing a white lab coat, sitting with a clipboard, and staring at the swings? We want our researcher to be inconspicuous and unobtrusively positioned—perhaps pretending to be a school monitor while secretly recording the relevant information. This type of observational study is called naturalistic observation : observing behavior in its natural setting. To better understand peer exclusion, Suzanne Fanger collaborated with colleagues at the University of Texas to observe the behavior of preschool children on a playground. How did the observers remain inconspicuous over the duration of the study? They equipped a few of the children with wireless microphones (which the children quickly forgot about) and observed while taking notes from a distance. Also, the children in that particular preschool (a “laboratory preschool”) were accustomed to having observers on the playground (Fanger, Frankel, & Hazen, 2012).

It is critical that the observer be as unobtrusive and as inconspicuous as possible: when people know they are being watched, they are less likely to behave naturally. For example, psychologists have spent weeks observing the behavior of homeless people on the streets, in train stations, and bus terminals. They try to ensure that their naturalistic observations are unobtrusive, so as to minimize interference with the behavior they observe. Nevertheless, the presence of the observer may distort the behavior that is observed, and this must be taken into consideration (Figure 1).

The greatest benefit of naturalistic observation is the validity, or accuracy, of information collected unobtrusively in a natural setting. Having individuals behave as they normally would in a given situation means that we have a higher degree of ecological validity, or realism, than we might achieve with other research approaches. Therefore, our ability to generalize the findings of the research to real-world situations is enhanced. If done correctly, we need not worry about people modifying their behavior simply because they are being observed. Sometimes, people may assume that reality programs give us a glimpse into authentic human behavior. However, the principle of inconspicuous observation is violated as reality stars are followed by camera crews and are interviewed on camera for personal confessionals. Given that environment, we must doubt how natural and realistic their behaviors are.

The major downside of naturalistic observation is that they are often difficult to set up and control. Although something as simple as observation may seem like it would be a part of all research methods, participant observation is a distinct methodology that involves the researcher embedding themselves into a group in order to study its dynamics. For example, Festinger, Riecken, and Shacter (1956) were very interested in the psychology of a particular cult. However, this cult was very secretive and wouldn’t grant interviews to outside members. So, in order to study these people, Festinger and his colleagues pretended to be cult members, allowing them access to the behavior and psychology of the cult. Despite this example, it should be noted that the people being observed in a participant observation study usually know that the researcher is there to study them. [1]

Another potential problem in observational research is observer bias . Generally, people who act as observers are closely involved in the research project and may unconsciously skew their observations to fit their research goals or expectations. To protect against this type of bias, researchers should have clear criteria established for the types of behaviors recorded and how those behaviors should be classified. In addition, researchers often compare observations of the same event by multiple observers, in order to test inter-rater reliability : a measure of reliability that assesses the consistency of observations by different observers.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally (Figure 3). Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveys allow researchers to gather data from larger samples than may be afforded by other research methods . A sample is a subset of individuals selected from a population , which is the overall group of individuals that the researchers are interested in. Researchers study the sample and seek to generalize their findings to the population.

There is both strength and weakness in surveys when compared to case studies. By using surveys, we can collect information from a larger sample of people. A larger sample is better able to reflect the actual diversity of the population, thus allowing better generalizability. Therefore, if our sample is sufficiently large and diverse, we can assume that the data we collect from the survey can be generalized to the larger population with more certainty than the information collected through a case study. However, given the greater number of people involved, we are not able to collect the same depth of information on each person that would be collected in a case study.

Another potential weakness of surveys is something we touched on earlier in this module: people do not always give accurate responses. They may lie, misremember, or answer questions in a way that they think makes them look good. For example, people may report drinking less alcohol than is actually the case.

Any number of research questions can be answered through the use of surveys. One real-world example is the research conducted by Jenkins, Ruppel, Kizer, Yehl, and Griffin (2012) about the backlash against the U.S. Arab-American community following the terrorist attacks of September 11, 2001. Jenkins and colleagues wanted to determine to what extent these negative attitudes toward Arab-Americans still existed nearly a decade after the attacks occurred. In one study, 140 research participants filled out a survey with 10 questions, including questions asking directly about the participant’s overt prejudicial attitudes toward people of various ethnicities. The survey also asked indirect questions about how likely the participant would be to interact with a person of a given ethnicity in a variety of settings (such as, “How likely do you think it is that you would introduce yourself to a person of Arab-American descent?”). The results of the research suggested that participants were unwilling to report prejudicial attitudes toward any ethnic group. However, there were significant differences between their pattern of responses to questions about social interaction with Arab-Americans compared to other ethnic groups: they indicated less willingness for social interaction with Arab-Americans compared to the other ethnic groups. This suggested that the participants harbored subtle forms of prejudice against Arab-Americans, despite their assertions that this was not the case (Jenkins et al., 2012).

Think it Over

Research has shown that parental depressive symptoms are linked to a number of negative child outcomes. A classmate of yours is interested in  the associations between parental depressive symptoms and actual child behaviors in everyday life [2] because this associations remains largely unknown. After reading this section, what do you think is the best way to better understand such associations? Which method might result in the most valid data?

According to our paper writer , it's a focused investigation that delves deep into the unique complexities of a particular subject. Rather than sifting through mountains of data, a case study allows us to zoom in and scrutinize the details, uncovering the 'whys' and 'hows' that often remain hidden in broader research.

A psychology case study is not about generalizations or sweeping theories; it's about the intricacies of real-life situations. It's the detective work of the field, aiming to unveil the 'story behind the data' and offering profound insights into human behavior, emotions, and experiences. So, while psychology as a whole may study the forest, a case study takes you on a journey through the trees, revealing the unique patterns, quirks, and secrets that make each one distinct.

The Significance of Psychology Case Studies

Writing a psychology case study plays a pivotal role in the world of research and understanding the human mind. Here's why they are so crucial, according to our ' do my essay ' experts:

• In-Depth Exploration: Case studies provide an opportunity to explore complex human behaviors and experiences in great detail. By diving deep into a specific case, researchers can uncover nuances that might be overlooked in broader studies.
• Unique Perspectives: Every individual and situation is unique, and case studies allow us to capture this diversity. They offer a chance to highlight the idiosyncrasies that make people who they are and situations what they are.
• Theory Testing: Case studies are a way to test and refine psychological theories in real-world scenarios. They provide practical insights that can validate or challenge existing hypotheses.
• Practical Applications: The knowledge gained from case studies can be applied to various fields, from clinical psychology to education and business. It helps professionals make informed decisions and develop effective interventions.
• Holistic Understanding: Case studies often involve a comprehensive examination of an individual's life or a particular phenomenon. This holistic approach contributes to a more profound comprehension of human behavior and the factors that influence it.

Varieties of a Psychology Case Study

When considering how to write a psychology case study, you should remember that it is a diverse field, and so are the case studies conducted within it. Let's explore the different types from our ' write my research paper ' experts:

How to Write a Psychology Case Study

Crafting a psychology case study requires a meticulous approach that combines the art of storytelling with the precision of scientific analysis. In this section, we'll provide you with a step-by-step guide on how to create an engaging and informative psychology case study, from selecting the right subject to presenting your findings effectively.

Step 1: Gathering Information for Subject Profiling

To create a comprehensive psychology case study, the first crucial step is gathering all the necessary information to build a detailed profile of your subject. This profile forms the backbone of your study, offering a deeper understanding of the individual or situation you're examining.

According to our case study writing service , you should begin by collecting a range of data, including personal history, demographics, behavioral observations, and any relevant documentation. Interviews, surveys, and direct observations are common methods to gather this information. Ensure that the data you collect is relevant to the specific aspects of the subject's life or behavior that you intend to investigate.

By meticulously gathering and organizing this data, you'll lay the foundation for a robust case study that not only informs your readers but also provides the context needed to make meaningful observations and draw insightful conclusions.

Step 2: Selecting a Case Study Method

Once you have gathered all the essential information about your subject, the next step in crafting a psychology case study is to choose the most appropriate case study method. The method you select will determine how you approach the analysis and presentation of your findings. Here are some common case study methods to consider:

• Single-Subject Case Study: This method focuses on a single individual or a particular event, offering a detailed examination of that subject's experiences and behaviors.
• Comparative Case Study: In this approach, you analyze two or more cases to draw comparisons or contrasts, revealing patterns or differences among them.
• Longitudinal Case Study: A longitudinal study involves tracking a subject or group over an extended period, observing changes and developments over time.
• Cross-Sectional Case Study: This method involves analyzing subjects at a specific point in time, offering a snapshot of their current state.
• Exploratory Case Study: Exploratory studies are ideal for investigating new or underexplored areas within psychology.
• Explanatory Case Study: If your goal is to uncover the underlying factors and mechanisms behind a specific behavior or phenomenon, the explanatory case study is a suitable choice.

Step 3: Gathering Background Information on the Subject

In the process of learning how to write a psychology case study, it's essential to delve into the subject's background to build a complete and meaningful narrative. The background information serves as a crucial context for understanding the individual or situation under investigation.

To gather this information effectively:

• Personal History: Explore the subject's life history, including their upbringing, family background, education, and career path. These details provide insights into their development and experiences.
• Demographics: Collect demographic data, such as age, gender, and cultural background, as part of your data collection process. These factors can be influential in understanding behavior and experiences.
• Relevant Events: Identify any significant life events, experiences, or transitions that might have had an impact on the subject's psychology and behavior.
• Psychological Factors: Assess the subject's psychological profile, including personality traits, cognitive abilities, and emotional well-being, if applicable.
• Social and Environmental Factors: Consider the subject's social and environmental context, including relationships, living conditions, and cultural influences.

Step 4: Detailing the Subject's Challenges

While writing a psychology case study, it is crucial to provide a thorough description of the subject's symptoms or the challenges they are facing. This step allows you to dive deeper into the specific issues that are the focus of your study, providing clarity and context for your readers.

To effectively describe the subject's symptoms or challenges, consider the following from our psychology essay writing service :

• Symptomatology: Enumerate the symptoms, behaviors, or conditions that the subject is experiencing. This could include emotional states, cognitive patterns, or any psychological distress.
• Onset and Duration: Specify when the symptoms or challenges began and how long they have persisted. This timeline can offer insights into the progression of the issue.
• Impact: Discuss the impact of these symptoms on the subject's daily life, relationships, and overall well-being. Consider their functional impairment and how it relates to the observed issues.
• Relevant Diagnoses: If applicable, mention any psychological or psychiatric diagnoses that have been made in relation to the subject's symptoms. This information can shed light on the clinical context of the case.

Step 5: Analyzing Data and Establishing a Diagnosis

Once you have gathered all the necessary information and described the subject's symptoms or challenges, the next critical step is to analyze the data and, if applicable, establish a diagnosis.

To effectively analyze the data and potentially make a diagnosis:

• Data Synthesis: Organize and synthesize the collected data, bringing together all the relevant information in a coherent and structured manner.
• Pattern Recognition: Identify patterns, themes, and connections within the data. Look for recurring behaviors, triggers, or factors that might contribute to the observed symptoms or challenges.
• Comparison with Diagnostic Criteria: If the study involves diagnosing a psychological condition, compare the subject's symptoms and experiences with established diagnostic criteria, such as those found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
• Professional Consultation: It is advisable to consult with qualified professionals, such as clinical psychologists or psychiatrists, to ensure that the diagnosis, if applicable, is accurate and well-informed.
• Thorough Assessment: Ensure a comprehensive evaluation of the data, considering all possible factors and nuances before reaching any conclusions.

Case Studies

Last updated 22 Mar 2021

Case studies are very detailed investigations of an individual or small group of people, usually regarding an unusual phenomenon or biographical event of interest to a research field. Due to a small sample, the case study can conduct an in-depth analysis of the individual/group.

Evaluation of case studies:

- Case studies create opportunities for a rich yield of data, and the depth of analysis can in turn bring high levels of validity (i.e. providing an accurate and exhaustive measure of what the study is hoping to measure).

- Studying abnormal psychology can give insight into how something works when it is functioning correctly, such as brain damage on memory (e.g. the case study of patient KF, whose short-term memory was impaired following a motorcycle accident but left his long-term memory intact, suggesting there might be separate physical stores in the brain for short and long-term memory).

- The detail collected on a single case may lead to interesting findings that conflict with current theories, and stimulate new paths for research.

- There is little control over a number of variables involved in a case study, so it is difficult to confidently establish any causal relationships between variables.

- Case studies are unusual by nature, so will have poor reliability as replicating them exactly will be unlikely.

- Due to the small sample size, it is unlikely that findings from a case study alone can be generalised to a whole population.

- The case study’s researcher may become so involved with the study that they exhibit bias in their interpretation and presentation of the data, making it challenging to distinguish what is truly objective/factual.

Why are psychology case studies important?

Case studies in psychology are crucial because they can be used to develop treatments, validate diagnoses, and provide evidence to support psychological theories. They can also enable future psychologists to review additional comprehensive empirical research to broaden their own case study investigations. The comparison of information from earlier case studies can aid future research development procedures.

What is a psychology case study?

A psychology case study is a comprehensive examination of a single individual, group of people, or event that draws on data from experiments, observations, and other sources. Psychologists gather data for a case study through experimentation, interviews, observation, psychometric testing, and case study archives. These studies typically investigate psychological mechanisms and behaviors to gather knowledge for subsequent investigations into a condition or behavior. Sometimes, a case study will look at every aspect of a person’s life and behavior.

Benefits of psychology case studies

Here are some common benefits of a psychology case study:

Types of psychology case studies

A research psychologist may choose to conduct one of the following six types of case studies:

How to write a psychology case study

If you’re considering writing your own case study, here are eight steps to get you started:

1. Gather information to create a profile for a subject

Before creating research methods and a hypothesis, it’s critical to gain as much knowledge as you can about the research topic. You can use prior case studies as supplementary data to conduct and better understand theories or information during your case study research. After gathering data from earlier studies, gather data on the topic from the following four sources:

2. Choose a case study method

When creating a psychology case study, there are two approaches to consider: the prospective approach and the retrospective approach. To choose the best approach, take into account the case study’s focus and the research you hope to uncover. In a prospective case study, the goal is to observe a person or group in order to identify and comprehend the psychological outcomes. Retrospective case studies analyze past events, such as a subject’s diagnosis, to identify potential influences on a subject’s psychological well-being and past behaviors.

3. Collect information regarding the subjects background

The subject’s history or background is presented in the first section of a case study. In this section, a research psychologist collects the following information:

4. Describe the subjects symptoms or problems

Include any mental, bodily, or sensory symptoms a subject may have in order to create an effective treatment plan. Including in your study any thoughts, emotions, or worries the subject has regarding their symptoms is beneficial. If the subject is tested, describe all results and evaluations that are pertinent to the case study.

5. Analyze the data and establish a diagnosis

This step entails analyzing and choosing the best diagnosis for the subject based on the information from your research. Explain each step of your research methods, as well as the symptoms of your subject, to provide evidence to support your diagnosis. Additionally, symptoms may serve as evidence that a person meets the requirements for a particular disorder.

6. Choose a treatment approach

Once you have reached a diagnosis, the following step in writing a psychology case study is to select a treatment strategy. Here are four treatment approaches you may decide to use:

7. Describe treatment goals and processes

Define the objectives of using this treatment, how you intend to use it, and any outcomes you anticipate occurring after treatment after choosing a treatment approach. Some objectives might be to completely eradicate symptoms or use the therapy to lessen some symptoms and implement coping mechanisms so the patient can resume a normal life. To provide more details on the diagnosis for future research, it’s crucial to record your treatment procedures and keep track of how the subject responds to them.

8. Write a discussion section

The discussion section appears as the final section of a psychology case study. You must describe all case study procedures, outcomes, and components in this section, along with any restrictions and how the study adds to prior research. This section also contains any psychological conclusions or hypotheses that may need additional study. You have the chance to review every aspect of your study in the discussion section and assess its accuracy, potential contributions to future research, and potential therapeutic strategies a psychologist might employ with a different patient who shares your history and symptoms.

Experiments are often used to help researchers understand how the human mind works. There have been many famous examples in psychology over the years. Some have shown how phenomena like memory and personality work. Others have been disproven over time. Understanding the research design, content, and analytical approach of case studies is important to verifying the validity of each study.

In considering case studies, researchers continuously test and reevaluate the conclusions made by past psychologists to continue offering the most up-to-date and effective care to modern clients. Prospective case studies are continually being developed based on previous findings from case studies, and multiple case studies done in one area can lend credence to the findings. Learning about the famous psychology case studies can help you understand how research studies continue to shape what psychologists know about the human experience and mind. 

Examples of famous psychology case studies

Hundreds of thousands of case studies have been done in psychology, and narrowing them down to a list of the most groundbreaking case studies can be challenging. However, the following seven case studies present findings that have defied expectations, achieved positive outcomes for humanity, and launched further research into existing knowledge gaps within the niche.

Phineas Gage

The case of Phineas Gage is perhaps the  most cited study  in psychology. This famous case study showed how different areas of the brain affect personality and cognitive ability. While working as a construction foreman on a railroad, Phineas Gage was involved in an accident in which a rod was pushed through his cheek and brain. He survived, but because of the accident, both his personality and his ability to learn new skills were affected.

Genie the "feral child" case study

Although an outdated term, "feral children" referred to children raised without human interaction, often due to abuse or neglect. One famous case study of a neglected child was done with a child known as Genie. She was raised in a single bedroom with little human interaction. She never gained the cognitive ability of an average adult, even though she was found at age 13. Later in life, she regressed and stopped speaking altogether. Her case has been studied extensively by psychologists who want to understand how enculturation affects cognitive development. It's one of many case studies on cognitive psychology  that have had an impact on this field.

Henry Molaison

The  case study of Henry Molaison has helped psychologists understand memory. It is one of the most famous case studies in neuroscience. Henry Molaison was in a childhood accident that left him with debilitating seizures. Doctors could stop the seizures by removing slivers of his brain's hippocampus, though they did not fully understand what they were doing at the time. As a result of this study, scientists learned how important the hippocampus is to forming long-term memories. After the surgery, Molaison could no longer form long-term memories, and his short-term memory was brief. The case study started further research into memory and the brain.

Jill Price case studies

Jill Price had one of a few documented cases of hyperthymesia, a term for an overactive memory that allowed her to remember such mundane things as what she had for dinner on an average day in August 20th years previously. Her  case study  was used as a jumping-off point to research how memory works and why some people have exceptional memories. 

However, through more research studying of the case, it was discovered that her overall memory was not exceptional. Rather, she only remembered details of her own life. She was diagnosed with obsessive-compulsive disorder (OCD), with memories being part of her obsession. This case study research is still relevant because this case has helped modern psychologists understand how mental illness affects memory.

John/Joan case study research

In the John/Joan  case study , a reputable sexologist tested his theory that nurture, not nature, determined gender. The case study has been cited extensively and laid the groundwork for other research studies into gender identity. However, the case study approach was not legitimate. In this case study, Dr. John Money performed surgery on an infant whose genitals were damaged during circumcision. 

The boy was raised as a girl; however, he never identified as female and eventually underwent gender-affirming surgery as an adult. Because Dr. Money didn't follow up with the patient appropriately and did not report adverse findings, the case study is still often cited as successful.

Ethics in a case study.

While case studies can provide valuable details and information from  psychology experiments and inspire further research, case studies are not definitive proof of a theory. Case study examples must be used ethically and legitimately. They can be used to support theories, but the research in these studies must be sound to be accepted by modern psychology.

When case studies are flawed through not having enough information or having the wrong information, they can be harmful. Valuable research hours and other resources can be wasted while theories are used for inappropriate treatment. Case studies can therefore cause as much harm as benefit, and psychologists are often careful about how and when they are used.

Practicing caution with case studies 

Those who are not psychologists and are interacting with studies can also practice caution. Psychologists and doctors often disagree on how case studies should be applied. In addition, people without education in psychology may struggle to know whether a case study is built on a faulty premise or misinformation. It can also be possible to generalize case studies to real world situations to which they do not apply. If you think a case study might apply to your case or that of a loved one, consider asking a therapist for guidance. 

When considering case study content and findings from psychology, it can be helpful to think of the cases as stories of real individuals. When you strip away the science and look at the case as a whole person in a unique situation, you may get more out of the study than if you look at it as research that proves a theory. 

Therapeutic implications of a case study

Case examples are sometimes used in therapy to determine the best course of treatment. If a typical case study from psychology aligns with your situation, your therapist may use the treatment methods outlined in the study. Psychiatrists and other mental health professionals also use case examples to understand mental illness and its treatment.

Researchers have reviewed the role of case studies in counseling and psychotherapy. In one study, the authors discussed how reading case studies benefits therapists, providing a conceptual guide for clinical work and an understanding of the theory behind the practice. They also stressed the importance of teaching psychotherapy trainees to do better case study research. They encouraged practitioners to publish more case studies documenting the methods they use in their practice.

How a case study research affects counseling

If you want to meet with a psychologist, counseling may benefit you. Therapists often use theories behind popular case studies and can discuss their implications with you. In addition, you may be able to participate in case studies in your area, as psychologists and psychiatrists often perform clinical trials to understand treatments on a deeper level.

Therapist reviews.

Out of the thousands of clinical studies that have been done in the realm of psychology, a few typical case studies are often mentioned above the rest. Consider reading through these types of case studies to learn more about how they worked and how psychology has changed over the years. You can also reach out to a therapist for further guidance and support in a specific mental health area.

Case studies can help the field of psychology, but psychotherapy is personal.

case study , detailed description and assessment of a specific situation in the real world created for the purpose of deriving generalizations and other insights from it. A case study can be about an individual, a group of people, an organization, or an event, among other subjects.

By focusing on a specific subject in its natural setting, a case study can help improve understanding of the broader features and processes at work. Case studies are a research method used in multiple fields, including business, criminology , education , medicine and other forms of health care, anthropology , political science , psychology , and social work . Data in case studies can be both qualitative and quantitative. Unlike experiments, where researchers control and manipulate situations, case studies are considered to be “naturalistic” because subjects are studied in their natural context . ( See also natural experiment .)

The creation of a case study typically involves the following steps:

• The research question to be studied is defined, informed by existing literature and previous research. Researchers should clearly define the scope of the case, and they should compile a list of evidence to be collected as well as identify the nature of insights that they expect to gain from the case study.
• Once the case is identified, the research team is given access to the individual, organization, or situation being studied. Individuals are informed of risks associated with participation and must provide their consent , which may involve signing confidentiality or anonymity agreements.
• Researchers then collect evidence using multiple methods, which may include qualitative techniques, such as interviews, focus groups , and direct observations, as well as quantitative methods, such as surveys, questionnaires, and data audits. The collection procedures need to be well defined to ensure the relevance and accuracy of the evidence.
• The collected evidence is analyzed to come up with insights. Each data source must be reviewed carefully by itself and in the larger context of the case study so as to ensure continued relevance. At the same time, care must be taken not to force the analysis to fit (potentially preconceived) conclusions. While the eventual case study may serve as the basis for generalizations, these generalizations must be made cautiously to ensure that specific nuances are not lost in the averages.
• Finally, the case study is packaged for larger groups and publication. At this stage some information may be withheld, as in business case studies, to allow readers to draw their own conclusions. In scientific fields, the completed case study needs to be a coherent whole, with all findings and statistical relationships clearly documented.

Case studies have been used as a research method across multiple fields. They are particularly popular in the fields of law, business, and employee training; they typically focus on a problem that an individual or organization is facing. The situation is presented in considerable detail, often with supporting data, to discussion participants, who are asked to make recommendations that will solve the stated problem. The business case study as a method of instruction was made popular in the 1920s by instructors at Harvard Business School who adapted an approach used at Harvard Law School in which real-world cases were used in classroom discussions. Other business and law schools started compiling case studies as teaching aids for students. In a business school case study, students are not provided with the complete list of facts pertaining to the topic and are thus forced to discuss and compare their perspectives with those of their peers to recommend solutions.

In criminology , case studies typically focus on the lives of an individual or a group of individuals. These studies can provide particularly valuable insight into the personalities and motives of individual criminals, but they may suffer from a lack of objectivity on the part of the researchers (typically because of the researchers’ biases when working with people with a criminal history), and their findings may be difficult to generalize.

In sociology , the case-study method was developed by Frédéric Le Play in France during the 19th century. This approach involves a field worker staying with a family for a period of time, gathering data on the family members’ attitudes and interactions and on their income, expenditures, and physical possessions. Similar approaches have been used in anthropology . Such studies can sometimes continue for many years.

Case studies provide insight into situations that involve a specific entity or set of circumstances. They can be beneficial in helping to explain the causal relationships between quantitative indicators in a field of study, such as what drives a company’s market share. By introducing real-world examples, they also plunge the reader into an actual, concrete situation and make the concepts real rather than theoretical. They also help people study rare situations that they might not otherwise experience.

Because case studies are in a “naturalistic” environment , they are limited in terms of research design: researchers lack control over what they are studying, which means that the results often cannot be reproduced. Also, care must be taken to stay within the bounds of the research question on which the case study is focusing. Other limitations to case studies revolve around the data collected. It may be difficult, for instance, for researchers to organize the large volume of data that can emerge from the study, and their analysis of the data must be carefully thought through to produce scientifically valid insights. The research methodology used to generate these insights is as important as the insights themselves, for the latter need to be seen in the proper context. Taken out of context, they may lead to erroneous conclusions. Like all scientific studies, case studies need to be approached objectively; personal bias or opinion may skew the research methods as well as the results. ( See also confirmation bias .)

Business case studies in particular have been criticized for approaching a problem or situation from a narrow perspective. Students are expected to come up with solutions for a problem based on the data provided. However, in real life, the situation is typically reversed: business managers face a problem and must then look for data to help them solve it.
