Multidimensional differences between adolescent substance abusers and users

High-school-aged adolescents responded to a 48-item survey about their substance use. From an original sample of 190 respondents, groups were created through consequence variables (e.g., school, family, medical, and legal problems) into abuse (n = 41) and use (n = 115) categories. Variables were organized along multidimensional lines: stimulus (e.g., frequency of substance use, use in school), organismic (e.g., age, grade), and response (e.g., driving a car while under the influence). From 27 comparisons of the abuse and use groups 16 significant differences emerged.
