Hybrid Effectiveness-Implementation Trial of a School-Based Teen Marijuana Checkup

The Teen Marijuana Checkup (TMCU) is a brief, school-based motivational enhancement therapy approach that has been systematically evaluated in three randomized controlled trials. It has demonstrated reliable beneficial effects in prompting voluntary participation in the intervention, as well as decreasing adolescent marijuana use. With TMCU now well-positioned for broad dissemination, its public health impact may be enhanced by further research addressing: 1) to what extent its documented efficacy under controlled conditions translates to real-world effectiveness, and 2) what support systems are most useful in promoting sustained integrity in its delivery by the available school-based personnel. This project will be conducted in schools in Washington State.
