Abstract: = 101 non-Hispanic white; ages 13-18) were randomized to two 1-hr individual sessions of MI or ACE. We examined 6-month outcomes and mechanisms of change across Hispanic and non-Hispanic white youth. Treatment response was comparable across ethnicities (Hispanic vs. non-Hispanic white youth). Additionally, adolescents in the MI condition showed greater reductions in alcohol use compared to those in ACE, with support for motivation and self-efficacy as mechanisms of treatment response. Direct effects of MI on cannabis use were not observed; however, a significant indirect effect of motivation was observed for reductions in cannabis use. Data support the efficacy of MI in reducing adolescent alcohol use, through the vehicle of enhanced motivation and self-efficacy. While consistent treatment response was observed for adolescent alcohol use across ethnicities (Hispanic vs. non-Hispanic white), further exploration into potential underexplored mechanisms of Hispanic adolescents' treatment response is requisite to strengthening prevention and intervention programming for Hispanic adolescents' cannabis use.
