N1 - Funding Information:
All participants completed a self-report survey on school grounds. This study was approved by an institutional review board and received a National Institutes of Health Certificate of Confidentiality. Passive parental consent and student assent were required for participation in the survey administration. Participants were given a participant number that linked their survey responses to their classroom attendance in LST and TimeWise lessons. Grade-level cohort was the unit of assignment in this study. All mainstream schools in this school district with a 6th grade implemented LST and TimeWise as part of standard school curriculum. Alternative schools did not take part in this intervention trial.

N2 - 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.
