What is a case study?

A case study is an in-depth analysis of a single individual or group, which allows for a comprehensive examination of various aspects of that individual or group’s behavior, personality, and experiences. This method is particularly useful in psychology and other social sciences when exploring complex phenomena that cannot be easily quantified or generalized across larger populations.

The strength of a case study lies in its detailed exploration of specific instances, which can provide valuable insights into particular psychological issues, treatment effects, or social dynamics. It often involves various data collection methods such as interviews, observations, and historical analyses, creating a rich, qualitative portrait of the subject being studied. This approach allows researchers to formulate hypotheses, gather evidence, or provide context for broader theories.

In contrast, the other options do not accurately capture the essence of a case study. A systematic analysis of a large population typically refers to different research methods like surveys or experimental studies that aim for statistical generalization but lack the depth of a case study. A collection of various research studies would be more aligned with meta-analysis or literature reviews rather than a single case study. Finally, a brief overview of clinical findings does not encompass the extensive and detailed nature of a case study.
