Objective: Rates of violence in Substance Use Disorder (SUD) treatment samples often exceed 50%, with studies showing rates of past-year violence >70% when considering violence occurring with either intimate partners or others. Violence has numerous costs to Veterans and their families, in terms of physical (e.g., injuries) and psychosocial problems (mental health, legal problems, marital problems, poorer functioning for their children, etc.). To date, only one treatment approach (Behavioral Couples Therapy - BCT) has been established that reduces both substance use and violence, and BCT focuses exclusively on the couples' relationship. Given that a small proportion of Veterans in SUD treatment have a partner willing or able to attend treatment, and that a substantial amount of violence occurs with non-partners, there is a clear need for interventions that do not require partner participation and focus on violence and relapse prevention more generally. Based on prior findings, new intervention approaches targeting the use of violence prevention skills and means of sustaining substance use remission are needed.
