Reliability of the Structured Clinical Interview for DSM-IV - Clinical Version translated into Portuguese

OBJECTIVES: To assess the reliability of a Portuguese version of the Structured Clinical Interview for DSM-IV - Clinical Version (SCID-CV). METHODS: Forty-five psychiatric patients at the university hospital of Ribeirão Preto, Brazil, were assessed twice in two independent interviews (test-retest). Inter-rater agreement analysis was done using the kappa coefficient (K). RESULTS: The weighted Kappa was excellent (Kw=0.83). Reliability was statistically significant for affective disorders (K=0.87); psychotic disorders (K=0.90); substance-related disorders (K=0.76); anxiety disorder (K=0.61); and for all specific diagnostic categories analyzed, except for agoraphobia without history of panic attacks (K=-0.04). CONCLUSIONS: The present Portuguese version of the SCID-CV showed good inter-rater reliability, but the lack of specific questions in the interview and specific diagnostic criteria for some disorders, such as agoraphobia without history of panic attacks, resulted in poor reliability.
