Introduction to Psychology/Case Studies

Case study in psychology refers to the use of a descriptive research approach to obtain an in-depth analysis of a person, group, or phenomenon. A variety of techniques may be employed including personal interviews, direct-observation, psychometric tests, and archival records. The psychology case studies are mostly used in clinical research to describe rare events and conditions, which contradict well established principles in the field of psychology.Christensen, L. B. (1994).“Experimental methodology"( 6th ed).,Simon & Schuster:Needham Heights, MA. . 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.Yin, R.(1994). “Case study research: Design and methods” (2nd ed.).Sage Publishing:Beverly Hills, CA. . 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. Advantages One major advantage of the case study in psychology is the potential for the development of novel hypotheses for later testing. Second, the case study can provide detailed descriptions of specific and rare cases. Disadvantages The major disadvantages of the case study in psychology is the inability to draw cause and effect relationships or test hypotheses. Further, with the case study it is impossible to generalize the findings to a wider population.
