SCL-90 symptom patterns: indicators of dissociative disorders.

The purpose of this study was to examine the SCL-90 profiles of adult outpatients with and without dissociative disorders. A total of 194 participants were administered the Structured Clinical Interview for DSM-IV Dissociative Disorders-Revised (SCID-D-R) and the Symptom Checklist-90 (SCL-90). Patients with dissociative identity disorder (DID) reported significantly higher SCL-90 Global Severity Index (GSI) and individual subscale scores than those without dissociative disorders. It is recommended that patients who are polysymptomatic on the SCL-90 be considered for follow-up dissociative symptom assessment to aid differential diagnosis and to inform subsequent treatment.
