Using consensus OPCRIT diagnoses

Abstract

BackgroundThe Operational Criteria Checklist (OPCRIT) generates diagnoses according to 12 operational diagnostic systems (e. g. DSM–III, DSM–III–R, Research Diagnostic Criteria, ICD–10)AimsTo examine the agreement between diagnoses generated by the OPCRIT, as completed by the interviewer, with a best-estimate lifetime procedure using the OPCRIT.MethodSubjects came from large mufti-generational bipolar or schizophrenia pedigrees (n=100), and from a sample of unrelated subjects with schizophrenia (n=40). We analysed the diagnostic agreement between OPCRIT diagnoses generated by the interviewer and our best-estimate OPCRIT diagnoses, according to DSM–III–R and ICD–10, using Cohen kappa statistics.ResultsExcellent agreement was found between interviewer OPCRIT diagnoses and OPCRIT diagnoses made by the best-estimate lifetime consensus procedure for DSM–III–R (κ=0.83) and ICD-10 (κ=0.81)ConclusionsResults suggest that this procedure for diagnostic assessment is an efficient alternative to classic best-estimate diagnosis procedures.
