Abstract

This study examined the long-term impact of Preparing for the Drug Free Years (PDFY) on young adult alcohol abuse disorder, addressing theory-based questions about how, and for whom, the program had its effects on the outcomes. Participants were 429 families of 6th graders enrolled in 33 rural schools located in the Midwestern United States. Schools were randomly assigned to conditions. Target adolescents (52% female) were interviewed periodically from age 11 to age 22; throughout adolescence, information was collected also from the youths' parents. Moderation and mediation analyses were conducted using regression analysis and structural equation modeling with covariates measured at baseline (age 11), mediators measured at posttest (age 12), and the outcome measured at the young adult follow-up (age 22). Results showed that PDFY reduced the rate of alcohol abuse among target young women, with evidence that this effect was mediated by increased prosocial skills. The rate of alcohol abuse among PDFY group men was not significantly different from that of control group men. Findings have implications for reducing the public health burden of alcohol abuse among young women.
