Does the Örebro Prevention Programme Prevent Youth Drinking? A Response to Özdemir & Stattin

Abstract

mechanisms, we tested whether the programme influenced youth drinking through its effect on parental attitudes. A separate model was fitted for each of the outcome measures. The results were clear across all models: the ÖPP programme had significant indirect effects on life-time drunkenness (est. = -0.057, P = 0.016), past-month drunkenness (est. = -0.072, P = 0.017), frequency of drinking (est. = -0.05, P = 0.003) and amount of drinking (est. = -0.06, P = 0.006) through its effect on parents' attitudes toward youth drinking. The indirect effects were robust, as bootstrapped confidence intervals confirmed the systematic indirect effect of the programme on youth outcomes. Thus, these findings show that when the programme influenced parents' attitudes, according to all the outcome measures, it succeeded in reducing youth drinking.
