Construct validation of a triangular love scale

Abstract

This article presents a construct validation of a love scale based upon a triangular theory of love. The article opens with a review of some of the major theories of love, and with a discussion of some of the major issues in love research. Next it briefly reviews selected elements of the triangular theory of love, according to which love can be understood as comprising three components—intimacy, passion, and decision/commitment. Then the article presents two studies constituting the construct validation of the love scale. The construct validation comprises aspects of internal validation—determination of whether the internal structure of the data is consistent with the theory—and external validation—determination of whether the scale based on the theory shows sensible patterns of correlations with external measures. The data are generally, but not completely supportive of the utility of the triangular love scale. © 1997 by John Wiley & Sons, Ltd.
