“…Drawing from the general literature, risk factors associated with substance use include: physical abuse (Snyder & Monroe, 2013;Widom & Hiller-Sturmhofel, 2001;Widom, Marmorstein, & Raskin White, 2006), parental substance abuse (Hawkins, Catalano, & Miller, 1992;Kilpatrick et al, 2000), depression (Lo & Cheng, 2007;Repetto, Zimmerman, & Caldwell, 2008;Snyder & Rubenstein, 2014), male gender (Aarons et al, 2008;Orton, Riggs, & Libby, 2009), White racial identity, and being older (Kilpatrick et al, 2000;Wallace et al 2003). Among child welfare-involved youth a key protective factor that buffers against substance use is living with biological parents (Cheng & Lo, 2011;Heneghan et al, 2013;Traube et al, 2012). The next section details the 2 S. M. SNYDER AND R. E. SMITH theoretical framework that justifies using these factors to understand polysubstance-use among youth in child welfare.…”
