The purpose of this study was to evaluate (a) the impact of a social-influences-based prevention program (the Midwestern Prevention Project) on the mediating variables it was designed to change and (b) the extent to which changes in those variables may have mediated program effects on drug use that were reported elsewhere (Pentz, Dwyer et al., 1989). The sample and design in our study are the same as those used in Pentz, Dwyer et al. The effects of the program on mediating variables and the relationship to drug use changes should supply useful information regarding how the school-based prevention program achieved its effects.
