abstract="This article reports results of a meta-analysis of the effects of a set of community coalitions that implemented science-based substance use prevention interventions as part of a State Incentive Grant (SIG) in Kentucky. The analysis included assessment of direct effects on prevalence of substance use among adolescents as well as assessment of what &quot;risk&quot; and &quot;protective&quot; factors mediated the coalition effects. In addition, we tested whether multiple science-based prevention interventions enhanced the effects of coalitions on youth substance use. Short-term results (using 8th-grade data) showed no significant decreases in six prevalence of substance use outcomes -- and, in fact, a significant though small increase in prevalence of use of one substance (inhalants). Sustained results (using 10th-grade data), however, showed significant, though small decreases in three of six substance use outcomes -- past month prevalence of cigarette use, alcohol use, and binge drinking. We found evidence that the sustained effects on these three prevalence outcomes were mediated by two posited risk factors: friends' drug use and perceived availability of drugs. Finally, we found that the number of science-based prevention interventions implemented in schools within the coalitions did not moderate the effects of the coalitions on the prevalence of drug use. Study limitations are noted.<p /> <p>Language: en</p>",
