The role of monitoring skills in mediating the association between parent's hazardous alcohol consumption and adolescents' drinking.

Background: This study aimed to investigate whether parental monitoring skills mediate the effect of hazardous parental alcohol consumption on adolescents' lifetime alcohol use.

Methods: This three wave longitudinal study was conducted with 884 families (n = 1,768 participants) to evaluate the effectiveness of a family-based drug prevention program for adolescents and parents across 12 Brazilian cities. We used structural equation mediation modeling to analyze the effect of hazardous parental alcohol consumption at baseline on adolescents' lifetime alcohol use at 12-month follow-up, mediated by parental monitoring skills latent dimension at 6-month follow-up.

Results: We found a significant indirect effect of parents' hazardous alcohol use on adolescents' alcohol use through parental monitoring (OR:1.18, 95%CI:1.02;1.36).

Conclusion: Our finding underscores the importance of comprehensive preventive family alcohol approaches targeting adolescent alcohol use, which should consider both parental drinking behavior and monitoring practices.
