Convergent and discriminant validity of selected assertiveness measures.

Used D. T. Campbell and D. W. Fiske's (see record 1976-20103-001) multitrait-multimethod design and D. N. Jackson's (see record 1976-00077-001) multimethod factor analysis to investigate the convergent and discriminant validity of selected assertiveness measures as compared with those of aggression and dominance. The selected assertiveness measures were the College Self-Expression Scale (J. P. Galassi et al; see record 1974-30156-001), the Wolpe-Lazarus Assertiveness Questionnaire (J. Wolpe and A. Lazarus, 1966), and global self-ratings of assertiveness. 159 undergraduates served as Ss. Results provide strong support for the convergent and discriminant validity of the assertiveness measures.
