title: Case ascertainment: the Composite International Diagnostic Interview.
abstract: OBJECTIVE
  To outline the utility of the Composite International Diagnostic Interview (CIDI) in the diagnosis of psychosis.
  
  
  METHODS
  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.
