The investigation may be of a single person, business, event, or group. The investigation involves collecting in-depth data about the individual entity through the use of several collection methods. Interviews and observation are two of the most common forms of data collection used.
Saul McLeodpublished Case studies are in-depth investigations of a single person, group, event or community. Typically, data are gathered from a variety of sources and by using several different methods e.
The research may also continue for an extended period of time, so processes and developments can be studied as they happen. The case study research method originated in clinical medicine the case history, i.
The case study is not itself a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.
Most of this information is likely to be qualitative i. The data collected can be analyzed using different theories e. All the approaches mentioned here use preconceived categories in the analysis and they are ideographic in their approach, i. Case studies are widely used in psychology and amongst the best known were the ones carried out by Sigmund Freud.
He conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.
Even today case histories are one of the main methods of investigation in abnormal psychology and psychiatry. For students of these disciplines they can give a vivid insight into what those who suffer from mental illness often have to endure.
Case studies are often conducted in clinical medicine and involve collecting and reporting descriptive information about a particular person or specific environment, such as a school. 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. In order to produce a fairly detailed and comprehensive profile of the person, the psychologist may use various types of accessible data, such as medical records, employer's reports, school reports or psychological test results.
The interview is also 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, work mates and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
This makes it clear that the case study is a method that should only be used by a psychologist, therapist or psychiatrist, i. 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.
The procedure used in a case study means that the researcher provides a description of the behavior. This comes from interviews and other sources, such as observation. The client also reports detail of events from his or her point of view. The researcher then writes up the information from both sources above as the case study, and interprets the information.
Interpreting the information means the researcher decides what to include or leave out. A good case study should always make clear which information is factual description and which is an inference or the opinion of the researcher.
Strengths of Case Studies Provides detailed rich qualitative information. Provides insight for further research. Permitting investigation of otherwise impractical or unethical situations.
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.Advantages and Disadvantages in Real-Life Studies Two of these case studies are the Tylenol Scandal and the Genie language study.
Let's look at the advantages and disadvantages of these two studies. Aug 18, · You have pointed out lots of advantages and disadvantages of case studies, there are also ethical issues, observations and interviews are typically used in case study research to gather data, so the ethical issues are broadly the same (e.g.
privacy, consent, risk of harm, etc). The main objective of this work is to present the case study method as a research approach and to consider issues relevant for the conduct using this method, analyzing its advantages and disadvantages that should be considered in light of the kinds of problems and questions to be answered.
Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach.
Advantages and Disadvantages of Case Studies A first step in identifying the advantages and disadvantages of case study method is to clarify the major attributes of this research strategy. Normally, a definition would be expected to specify such boundaries. The advantages far outweigh the disadvantages as the case study approach provides for experiential learning and is a great tool in stimulating learning in training programs.
