Secondary Effects of an Alcohol Prevention Program Targeting Students and/or Parents.
The secondary effects of an alcohol prevention program (PAS) on onset of weekly smoking and monthly cannabis use are examined among >3000 Dutch early adolescents (M age=12.64) randomized over four conditions: 1) parent intervention (PI), 2) student intervention (SI), 3) combined intervention (CI) and 4) control condition (CC). Rules about alcohol, alcohol use, and adolescents' self-control were investigated as possible mediators. PI had a marginal aversive effect, slightly increasing the risk of beginning to smoke at T1, and increased the likelihood of beginning to use cannabis use at T1 and T2. SI delayed the onset of monthly cannabis use at T3. CI increased the risk to use cannabis at T3. No mediational processes were found. In conclusion, though this study show mixed results, negative side effects of the PI were found, particularly at earlier ages. Moreover, these results indicate the need for multi-target interventions.
