Multivariable-Multimethod Convergence in the Domain of Interpersonal Behavior

While empirical studies of the domain of interpersonal behavior indicate a great deal of conceptual convergence, there are few data bearing on the convergent validity of indices of interpersonal behavior across modes of measurement within the same population of subjects. As part of a larger study of the assessment of interpersonal behavior, 64 Ss participated in a multivariable-multimethod investigation, and completed a variety of self-report assessment devices, direct self ratings, and peer ratings. Substantial convergence for three dimensions of interpersonal behavior, Aggressive Dominance, Affiliation-Sociability, and Autonomy, was obtained across all modes of measurement. The results have implications for the assessment of interpersonal behavior, the individual differences versus situational variance controversy, and associated theoretical and methodological problems in multivariable-multimethod-multisituational designs.
