The present study examined the associations of alcohol-specific socialization practices and heavy parental drinking with alcohol use in early adolescents. Cross-sectional nationwide survey data from 2599 parent-adolescent (mean age = 12.16) dyads were used to conduct logistic regression analyses. Onset of alcohol use as well as infrequent and regular drinking were associated with tolerant rules and attitude as reported by adolescents, and by a tolerant attitude as reported by parents. In contrast to former studies including middle and late adolescents, parental alcohol use was not found to be associated with early adolescent alcohol use, nor did parental alcohol use influence the impact of parental rules. Restrictive alcohol-specific socialization was, independent of parental alcohol use, related to absence of (regular) early adolescent drinking. Thus, this study demonstrated that in early adolescence alcohol-specific parenting is more important for adolescent drinking than parental alcohol use. (Contains 4 tables.)
