Measuring mood spectrum: Comparison of interview (SCI-MOODS) and self-report (MOODS-SR) instruments

Spectrum phenomena include, in addition to the typical DSM core symptoms, isolated or atypical symptoms, often of low severity, as well as trait-like behavioral features that arise as a result of coping with the psychopathology. We have demonstrated the psychometric properties of five Structured Clinical Interviews for the assessment of specific mood and anxiety spectrum conditions, including the Structured Clinical Interview for Mood Spectrum (SCI-MOODS). The present report describes the reliability of the self-report version (MOODS-SR) of the SCI-MOODS in a sample of 21 patients with a mood disorder and 20 control subjects. Agreement between the self-report and the interview formats was substantial. Intraclass correlation coefficients (ICC) ranged from 0.88 to 0.97. Our findings provide support for the reliability of the MOODS-SR questionnaire. Copyright (C) 2002 by W.B. Saunders Company.
