Transformational leadership and organizational commitment: mediating role of psychological empowerment and moderating role of structural distance
研究以新加坡一家大型公立医院的520名护士为样本，发现心理授权在变革型领导对员工组织承诺的影响中起中介作用，而领导与员工之间的结构距离（直接或间接领导）调节了这一关系。
Abstract Using a sample of 520 staff nurses employed by a large public hospital in Singapore, we examined whether psychological empowerment mediated the effects of transformational leadership on followers' organizational commitment. We also examined how structural distance (direct and indirect leadership) between leaders and followers moderated the relationship between transformational leadership and organizational commitment. Results from HLM analyses showed that psychological empowerment mediated the relationship between transformational leadership and organizational commitment. Similarly, structural distance between the leader and follower moderated the relationship between transformational leadership and organizational commitment. Implications for research and practice of our findings are discussed. Copyright © 2004 John Wiley & Sons, Ltd.
