Although conceptualized initially as a dyadic-level theory, scholars have since broadened the theoretical underpinnings of leader–member exchange (LMX) to account for its effects on group-level phenomena. LMX differentiation, for example, captures the extent to which variance in LMX quality within teams affects numerous outcomes (e.g., performance). However, the specific mechanisms by which LMX differentiation affects team-level outcomes remains virtually unknown. In an attempt to address this limitation, this study investigates the extent to which task and social cohesion mediate the effects of LMX differentiation on team performance. Results indicate that the negative effect of LMX differentiation on team performance is mediated by task cohesion but not by social cohesion. In addition, LMX differentiation was found to have a negative effect of social cohesion, which was also mediated by task cohesion. A discussion is offered in which the implications of these results are entertained.

LMX 差异化对团队绩效的影响:调查凝聚力的中介特性

尽管最初被概念化为二元层次理论,但后来学者们拓宽了领导-成员交换 (LMX) 的理论基础,以解释其对群体层次现象的影响。例如,LMX 差异化反映了团队内部 LMX 质量差异影响众多结果(例如绩效)的程度。然而,LMX 差异化影响团队级别结果的具体机制实际上仍然未知。为了解决这一限制,本研究调查了任务和社会凝聚力在多大程度上调节了 LMX 分化对团队绩效的影响。结果表明,LMX 分化对团队绩效的负面影响是由任务凝聚力而不是社会凝聚力介导的。此外,发现 LMX 分化对社会凝聚力有负面影响,这也是由任务凝聚力介导的。提供了一个讨论,其中考虑了这些结果的含义。
