| Abstract: | Because adolescents are unlikely to seek, receive, or complete treatment for alcohol and/or cannabis misuse, it is important to enhance the lasting impact of clinical contacts when they do occur. Adolescents (N = 506; 72.5% Hispanic) were randomized to motivational interviewing (MI) versus alcohol and cannabis education (ACE). Latent growth models estimated change over time. Significant reductions in alcohol use were observed, with slightly greater reductions by 12-month follow-up for MI. Both interventions significantly reduced cannabis use, with no treatment group differences. When outcomes were examined comparing Hispanic to non-Hispanic participants, there were no significant differences in intervention efficacy by group. MI's inherently client-centered and culturally adaptive approach may contribute to its equitable degree of behavior change for youth across race/ethnic backgrounds. |
