[Leadership behaviour and health - current research state].

The link between leaders' behaviour and health has only recently been the focus of scientific research and the results which already exist on this topic have, to date, not been systematically evaluated or summarized. The objective of this article is to make an attempt to provide a summarised overview of the current state of research. Subject-related databases list 42 publications dealing with the relationship between leaders' behaviour and the state of health and well-being of their employees. The literature discusses leaders' behaviour as being both a stressor (source of stress) and a resource. The publications discussed here also provide the first empirical evidence on the influence of various leadership styles on the health of the employees. In particular, transformational and employee-orientated leadership are considered to be beneficial to health. But the question of how leaders' behaviour influences health has not been satisfactorily explained. In most of the publications included, a direct link was assumed and, in the majority of cases, confirmed empirically. In addition, it also appears that there may be an indirect influence which may be moderated or mediated by, e. g., working conditions or the personality of the individual. The relatively small number of research examinations into the influence of leaders' behaviour on the health and well-being of their staff shows that there is a need for additional research. © Georg Thieme Verlag KG Stuttgart · New York.
