Abstract
OBJECTIVE: The aims of this trial, conducted 2004-2008, were to examine (1) the effectiveness of Project Towards No Drug Abuse (TND) at the one-year follow-up when implemented on a large scale; and (2) the relative effectiveness of two training approaches for program implementers. METHOD:A total of 65 high schools from 14 school districts across the United States were randomized to one of three conditions: regular workshop training, comprehensive implementation support, or standard care control. Physical education and health teachers delivered the program to students (n=2538). Program effectiveness was assessed with dichotomous measures of 30-day substance use at baseline and one-year follow-up. RESULTS: When the program conditions were considered in aggregate and compared to controls, the program showed a marginally significant effect in lowering marijuana use from baseline to the one-year follow-up. Significant program effects on hard drug use were achieved for baseline non-users only. There were no differences in the effects of the two program conditions. CONCLUSION: Positive outcomes may be achieved by trained teachers when they implement Project TND in real-world high school environments; however, program effects are likely to be weaker than those achieved in efficacy trials. Training workshops may be adequate to build capacity for successful program implementation.
