title: School Substance Use Norms and Racial Composition Moderate Parental and Peer Influences on Adolescent Substance Use.
abstract: Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid-western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school-level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School-level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school-level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use.
