“…For substance abuse specifically, prior evidence demonstrates meaningful racial ethnic differences in drug histories (Shillington & Clapp, 2003), specific drugs used (Moselhy & Telfer, 2002), health consequences of substance use (Iguchi, 2005), and the relation of spirituality (Strada & Donohue, 2006) and acculturation (Epstein, Botvin, & Diaz, 2000; Hahm, Lahiff, & Gutterman, 2003; Klonoff & Landrine, 2000; Strada & Donohue, 2006) to substance use attitudes. In addition, important racial ethnic differences that may affect treatment response have been demonstrated such as pathways to treatment (Iguchi, 2005; Shillington & Clapp, 2003), patterns of treatment engagement and retention (Campbell, Weisner, & Sterling, 2006; Jackson-Gilfort, Liddle, Tejeda, & Dakor, 2001), and cultural attitudes about mental health treatment (Buser, 2009). Together, these differences raise serious concerns regarding a priori assumptions that interventions developed for one ethnic minority group are appropriate for another group.…”
