A Meta-Analysis of LMX Differentiation and its Effect on Performance and Organizational Citizenship Behavior

摘要

Although leader-member exchange (LMX) differentiation represents a central assumption of LMX research, its effects on group and individual effectiveness and performance have not gone undebated. This study aims to synthesize and aggregate the empirical findings of past studies and estimate the true relationship between LMX differentiation and its relationship with group performance, individual performance, and organizational citizenship behavior. The results show that LMX differentiation is not significantly associated with either group or individual performance. However, the relationship between LMX differentiation and an element of extra-role performance (i.e. OCB) is significant.
