The Role of Parents and Peers in Early Adolescent Substance Use: An Examination of Mediating and Moderating Effects

We examined several models representing the relations among parenting practices, family structure, peer pressure, and drug use in a sample of 443 seventh graders. The setting was an urban school system serving a high percentage of African American students from low-income families. Analyses using structural equation modeling supported a mediation model in which both peer pressure and parenting practices had direct effects on drug use, with peer pressure mediating the influence of parenting. Within this model, family structure had a significant direct effect on parenting, however, contrary to hypotheses, children from two-parent families were more likely to report that they received adequate parenting than were children from single-parent extended families. Several gender differences were also found. Peer pressure was more highly related to drug use for girls than for boys, and the relation between parenting and peer pressure was stronger for boys. Examination of a model that included moderator effects revealed that the relation between peer pressure and drug use increased as a function of poor parenting. Results of our study underscore the importance of drug prevention efforts focused on parenting practices.
