Preparing for the drug free years: session-specific effects of a universal parent-training intervention with rural families.

Like their urban counterparts, adolescents from rural areas are at risk for health and behavior problems, including alcohol and other drug use. This study tested the effects on parenting practices of specific sessions of a parent-training intervention, Preparing for the Drug Free Years, designed to prevent adolescent substance abuse and other problem behaviors. Two hundred and nine rural families were randomly assigned to an intervention or a wait-list control condition. Analyses of covariance comparing adjusted posttest scores revealed that parents in the intervention condition reported significant improvements in parenting behaviors targeted by specific intervention sessions when compared with controls. Effects were most pronounced among mothers. No significant effects were found for nontargeted parenting behaviors, and targeted behaviors were most improved among parents attending relevant program sessions. These results strengthen the internal validity of the study and increase the plausibility that reported improvements were due to the intervention.
