A case study is a research method commonly used in psychology to investigate a specific individual, group, or event in depth. It involves collecting detailed information through various sources, such as interviews, observations, and documents, to gain a comprehensive understanding of the subject being studied. The process involves selecting a relevant subject, formulating research questions, gathering data through various methods, and analyzing the data. The researcher then draws conclusions based on the findings, identifying patterns, themes, and relationships within the data. The final step is to report the findings, typically presenting an introduction, methodology, results, discussion, and conclusion.
However, case studies have limitations, such as small sample sizes and being subjective, which may not generalize the findings to a larger population. Despite these limitations, case studies provide valuable insights and an in-depth understanding of complex phenomena in psychology.
