What describes the clinical or case study method for gathering data?

• A. It excludes interviews or observations in favor of large-scale surveys.
• B. It relies exclusively on laboratory experiments with random assignment.
• C. It uses only self-report questionnaires.
• D. It involves interviews, observations, test scores, and psychophysiological methods to gather a wide range of information on one child.

Answer: (D)

The main idea here is that the clinical or case study method gathers rich, multi-source information about a single individual (often a child) to understand their functioning in depth. It combines interviews, direct observations, test scores, and psychophysiological measures to build a comprehensive picture across different domains and settings. This approach emphasizes depth and context over broad generalization, focusing on the nuances of one case rather than a large sample. This is the best description because it explicitly includes multiple data sources—interviews, observations, tests, and physiological measures—and targets a wide range of information about one child. The other descriptions point to methods that are more limited or aim for generalizable results: large-scale surveys skip many of these data sources; laboratory experiments rely on random assignment and controlled conditions; self-report questionnaires alone miss the breadth of data gathered in a case study.
