Abstract

Abstract: Objective: The Bipolar Depression Rating Scale (BDRS) is a structured rating scale designed to assess depressive and mixed symptoms in bipolar disorder (BD). Previous studies evaluating the scale have been performed on small samples or on patients in a depressive phase, but not on patients in a mixed or manic phase. This study evaluated the Persian version of the BDRS regarding its factor structure, reliability, and validity in a large sample of Iranian women with BD in a depressive or mixed/manic phase. Methods: Three-hundred and one female BD inpatients completed the BDRS, the Beck Depression Inventory-II (BDI-II), the Hamilton Depression Rating Scale (HDRS), the Montgomery-Åsberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS). Results: The BDRS demonstrated a three-factor structure with good reliability. The BDRS and its psychological and somatic symptom clusters had stronger correlations with other measures of depressive symptoms than a measure of mania. The BDRS mixed symptom cluster also had a stronger correlation with a measure of mania than other measures of depression, supporting the scales' convergent and discriminant validity. Conclusions: The BDRS demonstrated psychometric validity in assessing depressive and mixed symptoms in Iranian women with BD in a depressive or mixed/manic phase. KEY POINTS: The Bipolar Depression Rating Scale (BDRS) was validated in Iranian women with BD. The BDRS showed a three-factor structure, similar to the original validation. The BDRS had good reliability based on Omega and test-retest coefficients. The findings provided evidence for the convergent and discriminant validity of the BDRS.
