A case study is an in-depth analysis of a person, group, event, or community. In studies, data are collected from various sources like personal interviews, direct observations, psychometric tests, and historical records to find the causes of one’s behaviour.
Case studies are applied in various study fields like psychology, medicine, anthropology, political science, and social sciences, business, etc.
Case study research methods are often used in clinical medicine to analyze patients’ personal and medical histories.
In psychology, case studies are restricted to the study of a particular individual, his biography, past life, and the current events that are presently happening in one’s day-to-day life.
Case studies offer a systematic approach towards finding events, collecting data, analyzing information, and communicating the results.
Case studies and case methods are often mistaken as the same, but they are not; case methods are research methods used to collect data and analysis that will further generate information needed for case studies.
case studies can be proved very useful at times. A case study offers a qualitative way of learning about a case through extensive description and contextual analysis.
One of the significant advantages of the case study in psychology is that it helps develop novel hypotheses for later testing.
Some of the other advantages of the case study method are:
Case studies provide far more detailed information on the rare or hard to study cases and the information concerning measurable or quantitative insights of the case and the detailed information related to the qualitative aspects of human behavior.
Case studies offer in-depth analysis and a multi-sided approach that studies even those aspects of human thinking that is impractical or unethical.
Following are the disadvantages of the case study method:
In the case studies, the data and information are collected through personal interviews, direct observations, psychometric tests, and historical records.
The researchers interview the subject of the case, his friends, parents, employer, workmates, and others who know him better and can state reliable facts about him.
The information collected through interviews involves comments from the person’s friends, parents, employer, workmates, etc.
Apart from the interviews, the case study method also involves simple observations concerning what is happening in the subject’s everyday life. It is a prospective method of the case study which means observing an individual for an extended period to study the developments of a particular disease as they happen.
Another method is a retrospective method which involves looking at the historical records of the subject of the case. It means going through the past background of the individual’s life to analyze the factors that have lead to the cause of the particular disease or illness.
The information collected through the case study method is more qualitative, i.e., based on the verbal description of one’s behavior.
After collecting all the data, you can analyze the following information through various techniques and theories like grounded theory, interpretative phenomenological analysis, text interpretation, etc. And then interpret the data and decide what is essential or what is not, and then conclude.
