Abstract

The purpose of this study was to develop an instrument for the measurement of present-state dissociative symptoms, the Clinician Administered Dissociative States Scale (CADSS). Reported here are interrater reliability and internal consistency of the CADSS, validity as assessed by comparisons with other instruments for the assessment of dissociation, and sensitivity of the CADSS to discriminate patients with dissociative disorders from patients with other psychiatric disorders and healthy subjects. Initial analyses indicated good interrater reliability and construct validity for the CADSS. Scores on the CADSS discriminated patients with dissociative disorders from the other groups.
