Randomized Controlled TrialOne-year follow-up evaluation of the Project Towards No Drug Abuse (TND) dissemination trial.
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. ⋯ 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.
