title: PTSD substance abuse comorbidity and treatment utilization.
abstract: The present study investigates the prevalence of posttraumatic stress disorder (PTSD) among a sample of treatment-seeking substance abusers and examines the relationship between PTSD comorbidity and rates of inpatient substance abuse treatment. Eighty-four patients (48 male and 36 female) admitted for detoxification at a private hospital were administered self-report measures of lifetime stressor events, PTSD symptomatology, and prior treatment history. Approximately one quarter of the sample was found to present with significant PTSD symptomatology. Women were more likely than men to have been physically and sexually abused, and women reported experiencing a greater number of traumatic events. Consequently, more women than men were classified as having possible PTSD. With respect to inpatient substance abuse treatment admission rates, the PTSD group reported a greater number of hospitalizations than their non-PTSD counterparts. Implications of these findings for routine trauma screening and more effective treatment for substance abusers with concomitant PTSD are highlighted.
