The impact of health-oriented leadership on follower health: Development and test of a new instrument measuring health-promoting leadership ** Based on previous research on leadership and follower health, three questions need to be answered or clarified. These questions refer to what health-specific leadership behavior is, whether motivational and cognitive aspects provide information beyond such behavior, and what role followers play in the leadership-health link. We introduce a new concept and measure of Health-oriented Leadership (HoL). This concept combines leaders' health-specific orientation towards followers (StaffCare; i.e., health behavior, health awareness, and value of health) and followers' health-specific attributes toward themselves (SelfCare). We present tests of construct and criterion validity from two field studies. The findings of Study 1 (N = 535) provide evidence for the construct validity of the HoL instrument. Study 2 (N = 383) examined the impact of StaffCare and SelfCare on follower health. As hypothesized, StaffCare as healthspecific leadership is related to followers' state of health, irritation, health complaints, and work-family conflicts. These effects were shown independently from transformational leadership indicating incremental validity. Moreover, the relationship between StaffCare and these outcomes is mediated by followers' SelfCare. The findings contribute to a more comprehensive picture of ways in which leaders can promote follower health by (a) engaging in StaffCare and (b) fostering followers' SelfCare.

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.

There is increasing interest in investigating work intensification as a new job demand. However, its contribution beyond the state of work intensity remains unclear and is thus far limited to two specific occupations. In the present study, I examine work intensification and work intensity simultaneously in their relations to health complaints based on a representative sample of the German workforce. The results show that the feeling of intensified work has unique effects beyond the state of intense work and even amplifies the effect of work intensity on psychosomatic complaints. With regard to musculoskeletal complaints, the effects are weaker and the interaction is not significant. Theoretical and practical implications of the findings are discussed.
