Use of self-report measures of crime-related posttraumatic stress disorder with substance use disordered patients.

Researchers have documented that approximately three-quarters of all patients in treatment for a substance use disorder (SUD) report a history of sexual or physical assault and that at least 25% of treatment-seeking SUD patients suffer from crime-related posttraumatic stress disorder (CR-PTSD). To address the pressing need to accurately evaluate symptoms associated with victimization, a battery of self-report instruments and a semi-structured interview were administered to 114 SUD patients. More than 90% of the SUD patients reported some type of victimization and approximately 38% met criteria for current CR-PTSD. The self-report battery correctly classified CR-PTSD status in 79% of the respondents with a sensitivity rate of 82% and a specificity rate of 74%. The results indicate that: (a) there is a high prevalence of CR-PTSD in SUD patients, (b) CR-PTSD should be evaluated in every SUD patient, and (c) the self-report battery utilized in the present study may serve as a valid tool for an initial CR-PTSD screening or to supplement a clinical interview.
