Dimensions of assertiveness: differential relationships to substance use in early adolescence.
We tested a multidimensional formulation of assertiveness and substance (tobacco, alcohol, and marijuana) use in 3 metropolitan-area school samples of adolescents aged 12-14 years. Three studies (N = 675, N = 1,430, and N = 5,545) included inner-city and surburban settings and included White, Black, and Hispanic students. Factor analysis of versions of the Gambrill-Richey Assertion Inventory indicated five independent dimensions of assertive behavior. Multiple regression analysis indicated that a dimension of Substance-specific Assertiveness was inversely associated with substance use, whereas dimensions of Social Assertiveness and Dating Assertiveness were positively associated with substance use. A dimension of General Assertiveness was unrelated to substance use. Interaction effects indicated that relations were stronger for girls for Substance and Social Assertiveness and for boys for Dating Assertiveness. Implications of the findings for models of assertive behavior and for design of primary prevention programs are discussed.
