Research Scenario
A clinical psychologist wanted to investigate depersonalisation-derealisation disorder by studying Patient Y. The psychologist originally planned to use a highly structured questionnaire to measure Patient Y's daily experiences. However, a peer suggested that it would be more valuable to conduct a detailed case study.
Explain one or more reasons why it might be better for the researcher to conduct a case study rather than use a questionnaire in this investigation.
