“…According to the risk–need–responsivity (RNR) model (Andrews & Bonta, 2010), treatment should be reserved for higher-risk groups of offenders (risk principle); focus on criminogenic needs (need principle); and be matched to individuals’ specific needs and other characteristics (responsivity principle). Indeed, SUD and other mental health treatment utilization has been shown to reduce recidivism risk among non-veterans (Cosden, Ellens, Schnell, Yamini-Diouf, & Wolfe, 2003; Garnick et al, 2014; Gumpert et al, 2010; Hiller, Knight, & Simpson, 1999) and veterans with criminal histories (Groppenbacher, Batzer, & White, 2003; Pandiani, Ochs, & Pomerantz, 2010). Engagement in SUD treatment has also been shown to improve outcomes such as employment (Dunigan et al, 2014) and stable housing (Gonzalez & Rosenheck, 2002).…”
