Objectives: To examine the relationship between an aggregate risk score (smoking, drinking, and number of sex partners) and measures of youth assets in a sample of 3439 youth aged 14?18 years. Methods: Linear regression models for African American and white males and females predicted an aggregate risk score. Results: After adjustments, the youth asset most predictive of risk was self/peer values regarding risk behaviors. Perceived school support was also predictive. Conclusions: Taking an ecological approach to the measurement of adolescent health behaviors contributes to our understanding of these risk behaviors.
