Measuring Treatment Response in Psychotic Depression: The Psychotic Depression Assessment Scale (PDAS) Takes both Depressive and Psychotic Symptoms into Account

摘要

BackgroundThere is no established psychometric instrument dedicated to the measurement of severity in psychotic depression (PD). The aim of this study was to investigate whether a new composite rating scale, the Psychotic Depression Assessment Scale (PDAS), covering both the psychotic and the depressive domains of PD, could detect differences in effect between two psychopharmacological treatment regimens.
