Examining the Link Between Leader Member Exchange and Subordinate Performance: The Role of Task Analyzability and Variety as Moderators
基于对一家大型城市医院152名成员的实地研究，发现任务可分析性和多样性感知调节了领导-成员交换质量与下属绩效之间的关系，当任务挑战性极高或极低时两者正相关，中等挑战时则无显著关系。
Results from afield study with 152 members of a large urban hospital indicate that the relationship between the quality of leader-member exchange (LMX) and subordinate performance is moderated by perceptions of task analyzability and variety. LMX and performance are found to be significantly related when task challenge is either very high or very low. Under these task conditions, data indicate that there is a positive link between LMX and performance such that a higher quality leader-member exchange correlates with higher levels of performance. On the other hand, analyses also reveal that when tasks are perceived to be moderately challenging, no significant relationship between LMX and performance is present. In other words, these data suggest that characteristics of the task act as moderating agents of the LMX/performance relationship. Results are discussed in terms of theory development, managerial implications, andfuture LMX research.
