The Construct Validity of the Tripartite Classification of Attitudes

The convergent, discriminant, and predictive validity of the tripartite model of attitudes is investigated. On the basis of a structural equation methodology, evidence is obtained for convergent validity. Moreover, a factor analysis of the attitude measures and measures of perceived extraneous events and personal and social normative beliefs provides evidence for discriminant validity. Finally, evidence for predictive validity based on actual and intended behaviors is found to be mixed. The implications of these findings for research pertaining to the prediction of consumer behavior are discussed.
