本研究比较了三种新兴的强调伦理道德行为的积极领导形式(即真实领导、伦理领导和公仆领导)与变革型领导与一系列组织相关措施的关联性。虽然学者们注意到了变革型领导和这些新的领导形式之间的概念重叠，但对变革型领导与这些领导形式之间的经验关系以及这些领导形式是否有能力(或缺乏)解释变革型领导之外的增量差异的研究还不够充分。作为回应，我们进行了一系列元分析，以全面评估这些新兴领导形式与现有文献中评估的变量之间的关系。其次，我们测试了每种领导形式在解释增量差异方面的相对表现，超越了变革型领导，在九种结果中。我们还提供了相对权重分析，以进一步评估新兴领导形式与变革型领导的相对贡献。真实领导力和道德领导力与变革型领导力之间的高度相关性，再加上它们的低增量差异，表明它们的实用性很低，除非它们被用来探索非常具体的结果。然而，仆人领导作为一种独立的领导方法显示出更大的前景，能够帮助领导力研究人员和实践者更好地解释广泛的结果。对未来的研究和这三种基于伦理/道德价值观的领导形式的效用提供了指导。
This study compares three emerging forms of positive leadership that emphasize ethical and moral behavior (i.e., authentic leadership, ethical leadership, and servant leadership) with transformational leadership in their associations with a wide range of organizationally relevant measures. While scholars have noted conceptual overlap between transformational leadership and these newer leadership forms, there has been inadequate investigation of the empirical relationships with transformational leadership and the ability (or lack thereof) of these leadership forms to explain incremental variance beyond transformational leadership. In response, we conducted a series of meta-analyses to provide a comprehensive assessment of these emerging leadership forms' relationships with variables evaluated in the extant literature. Second, we tested the relative performance of each of these leadership forms in explaining incremental variance, beyond transformational leadership, in nine outcomes. We also provide relative weights analyses to further evaluate the relative contributions of the emerging leadership forms versus transformational leadership. The high correlations between both authentic leadership and ethical leadership with transformational leadership coupled with their low amounts of incremental variance suggest that their utility is low unless they are being used to explore very specific outcomes. Servant leadership, however, showed more promise as a stand-alone leadership approach that is capable of helping leadership researchers and practitioners better explain a wide range of outcomes. Guidance regarding future research and the utility of these three ethical/ moral values-based leadership forms is provided.
