Associations between PTSD and intimate partner and non-partner aggression among substance using veterans in specialty mental health.


ABSTRACT: BACKGROUND:Risk factors of violence perpetration in veterans include substance use and posttraumatic stress disorder (PTSD); however, it is unknown whether these factors are associated with greater risk for partner or non-partner violence. This study investigated the associations between probable PTSD, heavy drinking, marijuana use, cocaine use, and partner and non-partner violence perpetration. METHODS:Self-report questionnaires assessing past-year partner and non-partner aggression (CTS2) as well as past-month substance use (SAOM), probable PTSD (PCL-C), and probable depression (PHQ-9) were administered to 810 substance using veterans entering VA mental health treatment. RESULTS:In bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, ?2=11.46, p=0.001, ?=0.12; non-partner physical, ?2=50.64, p<0.001, ?=0.25; partner injury, ?2=6.41, p=0.011, ?=0.09; non-partner injury, ?2=42.71, p<0.001, ?=0.23). In multiple logistic regression analyses that adjusted for sociodemographic characteristics, probable PTSD was independently associated with non-partner physical (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.97-4.05) and injury aggression (OR, 3.96; CI, 2.56-6.13). Cocaine and heavy drinking were independently associated with non-partner physical and injury aggression and non-partner injury aggression respectively. CONCLUSIONS:The results provide evidence that probable PTSD, heavy drinking, and cocaine use are associated with increased risk of non-partner violence perpetration in substance using veterans. These results underscore the importance of screening for PTSD symptoms and violence perpetration towards non-partners in substance using veterans presenting for treatment.
