ETHNIC AND GENDER DIFFERENCES IN RISK FOR EARLY ADOLESCENT SUBSTANCE USE

This study examined interpersonal and intrapersonal risk for substance use in a sample of Caucasian and Hispanic early adolescents. A total of 1170 sixth and seventh graders, equally divided by gender, participated. Interpersonal risk was assessed by susceptibility to peer pressure, parental monitoring, peer substance use, parent-child involvement, and school adjustment. Intrapersonal risk was measured via self-efficacy, impulsivity, aggression, depression, and academic achievement. As expected, mean level of use did not differ between ethnic groups. Regression analyses indicated susceptibility to peer pressure and peer alcohol use were the best-predictors of individual substance use. These findings were consistent across gender and ethnicity. In all groups, interpersonal variables accounted for more variance in predicting risk (49% for Hispanic males) than intrapersonal variables (0% for Hispanic females). Findings are discussed (1) in terms of examining mean levels vs. the underlying pattern predicting substance use, and (2) regarding implications for prevention efforts in early adolescence.
