Abstract
Most organizational systems today are hierarchically arranged, and our under standing of formal leadership holds great significance in both theory and application. One of the crucial elements that influences role-taking in an organizational setting is the interpersonal exchange relationship that develops between a superior and a role incumbent. This interactional, interpersonal element is the crux of Leader- Member Exchange-a scale which serves as a measure of the social exchange relationship that can develop between two organizational interactants. The research reported in this article is a confirmatory factor analysis of the Leader-Member Exchange (LMX) scale, and a test of a nomothetic network for the LMX factors. The scale was found to have two factors that were highly correlated. All correlations of the two LMX factors with factors in the nomothetic net have overlapping confidence intervals. The findings support the construct validity of the Leader-Member Ex change scale. This research provides added evidence that increased understanding of Leader-Member Exchange, coupled with an increased attention to the dynamics of the superior-subordinate relationship, can lead to improved organizational opera tion.
