Initiative Description: Systematic approach to reviewing substance use prevention programs introduced in elementary school (K-6th grade). Thirty published evaluation studies of 24 elementary school-based substance use prevention programs were reviewed.
Study Results: Among 27 evaluation studies that examined program effects on substance use, 56% (n = 15) found significant decreases. In addition, programs most often demonstrated effects on increasing negative substance use attitudes, increasing knowledge, decreasing perceptions of prevalence rates (i.e., descriptive norms), and improving resistance skills.
