Abstract

Two evidence-based interventions, Life Skills Training and TimeWise, were combined in an effectiveness trial. Participants were predominately African American youth (N = 715; M age = 12). The study authors provide an empirical demonstration of the implications of incorporating dosage information in intervention outcome analyses. Study results showed no program-related benefits for drug use. Results indicated intervention-related benefits for assertiveness and anxiety management skills and drug use intentions as well as a reduction in detrimental leisure motivations. High program exposure and lesson coverage tended to be connected to intervention benefits. Study findings also documented ways that dosage information provides insight into interventions and their effects.
