Effects of Parental Monitoring, Permissiveness, and Injunctive Norms on Substance Use Among Mexican and Mexican American Adolescents.

The prevention literature has given little attention to how parental influences affect substance use among Mexican origin adolescents, even though they form part of the largest ethnic minority group in the United States. This study explored the effects of three types of parental influences-parental monitoring of the child's whereabouts, degree of parental permissiveness, and the strength of parental injunctive norms discouraging substance use-on alcohol, cigarette, and marijuana use and anti-drug norms. Results showed that parental permissiveness and parental injunctive norms, particularly anti-drug injunctive norms, had the strongest effects on the substance use outcomes, but parental monitoring generally was not a significant predictor. These results and implications for prevention are discussed in light of Mexican cultural norms toward substance use, gender roles, and family roles.
