This study attempted to assess the degree of empirical convergence of various measures of the dimensions of interpersonal behavior when method variance is controlled. A total of 83 undergraduates (38 males, 45 females) were administered the Personality Research Form (PRF) and several self-report measures of social anxiety and effectiveness. In addition, they participated in a forced-interaction task with a confederate, from which ratings of anxiety and effectiveness were obtained. A two-step principal-components procedure was used in order to control method variance. Substantial cross-domain convergence was found in three of the four second-order components, two of which (Social Competence and Impulse Expression vs Control) clearly represented dimensions of interpersonal behavior. Strong support was found for the validity of several PRF components as well as of other instruments used as measures of constructs. Results suggest that the purported failure of trait constructs in accounting for behavioral variance may be more the result of methodological factors than of theoretical inadequacy.
