Abstract
Introduction and Aims. The international literature suggests that traumatic events are common for patients with substance use disorders (SUDs), and are often associated with the development of post‐traumatic stress disorder (PTSD) and other psychiatric comorbidities. However, limited research has been conducted among Australian SUD patients. The aim of the present study was to examine the prevalence of these disorders in a group of Australian patients admitted for detoxification.Design and Methods. Data were collected from 253 inpatients using a modified version of the Composite International Diagnostic Interview, the 10‐item Trauma Screening Questionnaire, the Zung Self‐rating Depression Scale and questions from the PsyCheck.Results. Approximately 20% of inpatients experienced moderate to severe depressive symptoms, and 37% had a lifetime history of self‐harm or attempted suicide. Approximately 80% of patients had experienced at least one traumatic event, most experiencing multiple traumas. The mean age of first trauma was 14 years. Almost 45% of patients screened positive for current PTSD symptoms. Women were nine times more likely to have been raped and five times more likely to have been sexually molested than men. PTSD symptoms were associated with greater trauma exposure, younger age of first trauma, specific trauma types, moderate to severe depressive symptoms and a history of self‐harm or attempted suicide. Despite their difficulties, patients with PTSD symptoms had high rates of retention in treatment.Discussion and Conclusions. Patients entering treatment for SUDs should be assessed for PTSD, depression and suicidality. These conditions impact significantly on treatment outcomes, and require the development of appropriate treatment strategies.[Dore G, Mills K, Murray R, Teesson M, Farrugia P.
