AbstractThis study examined early adolescent risk for substance use in a sample of 1,170 sixth and seventh graders. Risk was assessed by inspecting the predictive strength of thirteen continuous variables from the interpersonal (peer pressure, peer substance use, parental monitoring, parent-child involvement, academic achievement, and school adjustment) and intrapersonal (self efficacy, impulsivity, withdrawal, depression, somatization, delinquency, and aggression) domains. Consistent with expectations, mean levels of substance use did not differ by gender or ethnicity (Caucasians and Hispanics). In addition, model-free LISREL analyses revealed underlying process similarity of predictors between sixth and seventh graders and between Caucasians and Hispanics. Interpersonal variables accounted for significantly more variance in early adolescent lifetime substance use than intrapersonal variables (39% versus 25%). Finally, weighting continuous independent predictors did not meaningfully improve prediction of lifetime substance use. The importance of process similarity and the significance of the peer domain in early adolescent substance use are discussed.
