There has been an increasing shift towards individually owned leader development programs within organizations. Whilst leadership coaching is one of these and is gaining in popularity, the mechanisms of its effect remain poorly understood. We develop and investigate a model in which leadership coaching enhances leader effectiveness through coaching’s positive effect on authentic and change-oriented leadership behaviours as well as self-efficacy. To assess the model, multi-source data were collected for organizational leaders (N = 70) pre- and post-coaching. To investigate mechanisms of coaching’s effect, relations between latent change scores were assessed in structural equation modelling using partial least squares indicating that after accounting for base-line scores, coaching-related increases in authentic leadership behaviour has the largest total effect on leadership effectiveness.

当前，组织内部正日益转向推行个人主导的领导者发展计划。领导力教练（leadership coaching）作为此类计划之一，其受欢迎程度不断提升，但该干预手段的作用机制仍有待深入阐释。本研究构建并检验了一个理论模型，该模型提出：领导力教练可通过对真实型领导与变革导向型领导行为以及自我效能感产生积极影响，进而提升领导者效能。为评估该模型，我们针对样本量N=70的组织领导者收集了教练干预前后的多源数据。为探究领导力教练的作用机制，我们采用偏最小二乘结构方程建模对潜变量变化得分间的关系进行分析，结果表明：在控制基线得分的前提下，与教练干预相关的真实型领导行为提升对领导者效能的总效应最为显著。
