The trait theory of leadership is advanced by a joint investigation of the mediating role of (a) leadership self-efficacy (LSE = leader's perceived capabilities to perform leader roles) in linking neuroticism, extraversion, and conscientiousness with leader effectiveness and (b) the moderating role of job demands and job autonomy in influencing the mediation. Using K. J. Preacher, D. D. Rucker, and A. F. Hayes' (2007) moderated mediation framework, the authors tested the model (over a 2-year period) with matched data from 394 military leaders and their supervisors. Results showed that LSE mediated the relationships for neuroticism, extraversion, and conscientiousness with leader effectiveness. Moderated mediation analyses further revealed that LSE mediated the relationships for (a) all 3 personality variables for only those leaders with low job demands; (b) neuroticism and conscientiousness for only those leaders with high job autonomy; and (c) extraversion, regardless of a leader's level of job autonomy. Results underscore the importance of accounting for leaders' situational contexts when examining the relationships between personality, LSE, and effectiveness.
领导特质理论是通过一项联合调查提出的，该调查研究了以下两方面内容：（a）领导自我效能感（LSE = 领导者对履行领导角色能力的感知）在神经质、外向性和尽责性与领导效能之间的联系中所起的中介作用；（b）工作要求和工作自主性在影响这种中介作用时所起的调节作用。作者使用K. J. 普雷彻、D. D. 拉克尔和A. F. 海斯（2007年）的调节中介框架，用来自394名军事领导者及其上级的匹配数据对该模型进行了为期两年的测试。结果表明，LSE介导了神经质、外向性和尽责性与领导效能之间的关系。调节中介分析进一步显示，LSE介导了以下几种关系：（a）仅对那些工作要求低的领导者而言，LSE介导了所有这三种人格变量与领导效能之间的关系；（b）仅对那些工作自主性高的领导者而言，LSE介导了神经质和尽责性与领导效能之间的关系；（c）无论领导者的工作自主性水平如何，LSE都介导了外向性与领导效能之间的关系。研究结果强调了在考察人格、LSE和效能之间的关系时，考虑领导者情境的重要性。
