Abstract
Objective: To outline the utility of the Composite International Diagnostic Interview (CIDI) in the diagnosis of psychosis.
Method: Report current situation.
Results: The CIDI was designed as a fully structured interview to be used by lay interviewers. It generates false positive diagnoses in community surveys and false negative diagnoses in psychiatric settings. A new psychosis module has been developed to reduce these problems.
Conclusions: The diagnosis of psychosis by fully structured diagnostic interviews is difficult.
