This session will outline the comprehensive approach to drug prevention education utilized in the Stay on Track curriculum, the measurement strategy employed to assess its effectiveness, and the outcomes of the latest large-scale national implementation. The results are further analyzed to differentiate students reporting having family members actively serving in the military as well as those reporting a current family member's deployment. The comprehensive approach encompasses the development and utilization of evaluation quality tools, fidelity measures, and engagement with certified implementers throughout the evaluation cycle. Additionally, a summary of the attitude and intention outcomes associated with illicit substance use, and the complex findings associated with students reporting family member deployment will be provided. Overall results for 36,664 sixth, seventh, and eighth graders who participated in the program will also be presented.#DrugPreventionEducation #EvaluationUse #HealthEvaluation #Deployment #EvaluationTools #2011Conference #MilitaryFamilies #Alcohol,DrugAbuse,andMentalHealth #ArtsCultureandAudiences #EvaluationLifeCycle #StayonTrack
