Leader-member exchange (LMX) differentiation, the extent to which the leader forms different quality exchange relationships with group members, is the fundamental premise of LMX theory. The present study tests whether, why, and when LMX differentiation increases group outcomes. More specifically, I suggest a dual perspective model of LMX differentiation and group effectiveness, which includes b...

Available online 20 January 2012 Although the differential treatment of team members by their leader is at the heart of Leader– Member Exchange (LMX) theory, empirical studies exploring the role of within-team LMX differentiation in relation to team outcomes are still relatively scarce. This study among 269 Dutch secondary school teachers from 33 different teams tested the hypotheses that the r...

This research examines leader-member exchange (LMX) at the group level as a moderator of the relationships between demographic (i.e., race, age, gender) and tenure diversity and group turnover. Drawing primarily from LMX, social categorization, and expectation states theories, we hypothesized that through the pattern of LMX relationships that they develop with followers, group managers influenc...

A B S T R AC T We proposed that the social exchange relationships individuals form in the workplace would mediate the relation between perceptions of interactional and distributive justice and social loafing. Specifically, we argued that both leader–member exchanges (LMX) and team–member exchanges (TMX) would mediate the relation between interactional justice and social loafing, and that LMX wo...

This article provides a meta-analytic review of the relationship between the quality of leader-member exchanges (LMX) and citizenship behaviors performed by employees. Results based on 50 independent samples (N = 9,324) indicate a moderately strong, positive relationship between LMX and citizenship behaviors (rho = .37). The results also support the moderating role of the target of the citizens...

Research into Leader-Member Exchange (LMX) theory has been gaining momentum in recent years, with a multitude of studies investigating many aspects of LMX in organizations. Theoretical development in this area also has undergone many refinements, and the current theory is far different from the early Vertical Dyad Linkage (VDL) work. This article uses a levels perspective to trace the developme...

BACKGROUND AND STUDY AIMS Although endoscopic resection is widely used for the treatment of superficial colorectal neoplasms, the rate of local recurrence of lesions with a positive or indeterminate lateral margin on histologic evaluation is unclear. We aimed to demonstrate the relationship between lateral margin status and local recurrence after the endoscopic resection of intramucosal colorec...

This article seeks to raise awareness of the leader-member exchange (LMX) theory of leadership and its potential benefit to the health information management (HIM) profession. A literature review that was conducted identified a leadership challenge for HIM practitioners. The review also provides examples of leadership definitions, and potential benefits of LMX to HIM professionals in leading pe...
