Résumé : |
Purpose: This study examined whether adolescents receiving Motivational Interviewing (MI) intervention have different outcomes compared to those receiving Motivational Incentives (Motivational Interviewing combined with Contingency Management; MI + CM).
Method: A total of 136 adolescents (from a parent study of 220 adolescents) with problematic substance use were recruited from 8 high schools in Washington State, where they completed either 8-weeks of MI or MI + CM. Frequency of marijuana use was assessed at baseline, at the end-of-treatment, and at 16-week follow-up. Results: A balanced and matched sample was created using propensity scores, then analyzed using Hierarchical Linear Modeling (HLM). Multilevel regression analyses revealed that adolescents who received MI + CM exhibited a greater reduction in use across time (p Conclusion: These results suggest that the inclusion of contingencies into adolescent marijuana treatment decreases the end-of-treatment frequency of marijuana use and related consequences while increasing the use of coping strategies and the pursuit of additional treatment. Highlights: We examined the effectiveness of a school-based Motivational Incentives intervention. Contingencies condition decreased marijuana use in adolescents at 8 week follow up. Coping skills and treatment utilization increased in the contingency condition. Use of coping skills mediated the treatment effect and may be a mechanism of change. |
