Risk factors for revictimization during treatment in patients with co-occurring SUD and PTSD
Abstract
ABSTRACT Introduction: A host of cross-sectional studies have identified problematic substance use and post-traumatic stress symptoms as risk factors for repeated interpersonal violence (revictimization) in college samples. However, it remains unclear which factors are associated with revictimization for patients who meet diagnostic criteria for both substance use disorder (SUD) and post-traumatic stress disorder (PTSD). The identification of factors associated with revictimization is an important step towards preventing violence against people with psychiatric disorders and can inform treatment. Method: Data were based on the Treatment of PTSD and Addiction (TOPA) study, a randomized controlled trial including N = 209 patients that received inpatient and outpatient treatment for SUD and PTSD. We selected participants who had experienced interpersonal victimization at baseline (N = 203) and assessed revictimization across the 9-month follow-up period. Revictimization included: physical violence, violence with a gun, sexual violence, and ‘other unwanted sexual experience’. The risk factors we investigated were severity of PTSD, severity of alcohol and drug use disorder, interpersonal difficulties, sex, and age. We analysed the data using logistic regression analyses with multiple imputation for missing data. Results: Physical violence was the most common type of revictimization during the study period (26.0%), closely followed by ‘other unwanted sexual experience’ (20.0%).…
