Too much of a good thing: the curvilinear effect of leader-member exchange on stress.

Organizational researchers have given considerable attention to the construct of leader-member exchange (LMX). Numerous studies have empirically supported the negative correlations between LMX relationships and unwanted individual outcomes, including stress. However, in the present study, the authors investigated whether the relationship is best represented as linear or curvilinear. The authors tested their research hypothesis in two organizational samples of 120 and 402 employees, respectively, and found support for the nonlinear relationship in both samples. The authors described strengths, limitations, practical implications, and directions for future research.
