Leadership, followers' mental health and job performance in organizations: A comprehensive meta‐analysis from an occupational health perspective
通过元分析考察了变革型、关系导向、任务导向、破坏型领导及领导-成员交换与追随者心理健康（情感症状、倦怠、压力、幸福感等）的关系，并检验了心理健康在领导力与工作绩效间的中介作用。
Summary The present meta‐analysis investigates the associations between leadership, followers' mental health, and job performance by taking into account different groups of leadership constructs including transformational leadership, relations‐oriented leadership, task‐oriented leadership, destructive leadership, and leader–member exchange. Six categories of mental health‐related outcomes are considered representing both negative and positive mental health states of followers, namely, affective symptoms, burnout, stress, well‐being, psychological functioning, and health complaints. Meta‐analytic models are used to estimate the association between these categories of leadership and mental health. Our results reveal that transformational leadership, a high quality of relations‐oriented and task‐oriented leadership behavior, as well as a high quality of leader–follower interaction are positively associated with mental health. In contrast, destructive leadership is strongly negatively associated with mental health. In addition, the mediation effects of leadership on job performance via mental health are estimated. Results partially support the mediating role of mental health concerning the relationship between leadership and job performance. Our results emphasize the importance of leadership as an occupational health factor, and they may serve as basis for the planning and designing of occupational health policies and interventions despite existing research limitations.
