Participants completed a battery of psychometrically-sound, self-report measures of psychological functioning, environmental stress, drug abuse, and alcohol abuse. Four multiple regression analyses were conducted to determine the joint and independent predictors of drug abuse and alcohol abuse, for males and for females. Multiple regression analysis revealed that seven variables -- age, depression, impulsivity, low self-esteem, delinquent predisposition, low peer insecurity, and history of child abuse -- jointly predicted both drug and alcohol abuse, for both males and females. However, several differences were found with respect to which variables made independent contributions to the predictive models -- with only delinquent predisposition making a significant independent contribution for all four conditions. We found distinct patterns of psychosocial predictor variables for drug and alcohol abuse, as well as distinct patterns for males and females. These results may reflect differing risk factors for drug abuse and alcohol abuse in adolescent psychiatric patients -- and differing risk factors for males and females. Such differences have potential implications for prevention and treatment.
