Risk, protection, and substance use in adolescents: a multi-site model

This article reports findings from a national longitudinal cross-site evaluation of high-risk youth to clarify the relationships between risk and protective factors and substance use. Using structural equation modeling, baseline data on 10,473 youth between the ages of 9 and 18 in 48 high-risk communities around the nation are analyzed. Youth were assessed on substance use (cigarette, alcohol, and marijuana use), external risk factors including family, school, peer and neighborhood influences, and individual risk and protective factors including self-control, family connectedness, and school connectedness. Findings indicate strong direct relationships between peer and parental substance use norms and substance use. Individual protective factors, particularly family and school connectedness were strong mediators of individual substance use. These findings suggest that multi-dimensional prevention programming stressing the fostering of conventional anti-substance use attitudes among parents and peers, the importance of parental supervision, and development of strong connections between youth and their family, peers, and school may be most effective in preventing and reducing substance use patterns among high-risk youth.
