“…Second, following the literature, which shows that MI consistent therapist skills are positively related to treatment outcomes for adolescents through adults (e.g., Barnett, Moyers, et al, 2014; Gaume, Magill, et al, 2014; Moyers, Martin, Houck, Christopher, & Tonigan, 2009), we predicted that therapists’ greater use of MI skills would relate to better treatment response (less substance use frequency and related problems) for both Hispanic and non-Hispanic youth at the three-month follow-up. Third, consistent with prior theoretical work, which suggests that different factors may be salient to Hispanic youth’s treatment response, thus necessitating examination of therapeutic processes and outcomes for Hispanic youth (Feldstein Ewing et al, 2012; Salvador, DeVargas, & Feldstein Ewing, in press), we hypothesized that therapists would show greater MI skills with non-Hispanic versus Hispanic youth.…”
