Abstract
A social learning theory of deviant behavior is tested with survey data on adolescent drinking and drug behavior. The theory is strongly supported. The major explanatory variables from that theory, differential association, differential reinforcement, definitions, and imitation combine to account for 68% of the variance in marijuana use (39% of abuse) and 55% of the variance in alcohol use (32% of abuse) by adolescents. The study demonstrates that central learning concepts are amenable to questionnaire measurement, and the findings indicate that social learning theory will do well when tested with other forms of deviant behavior.
