Leader support and responses to work in US nurses: A test of alternative theoretical perspectives

Abstract A number of theoretical perspectives as well as common wisdom suggest that leader support is important for alleviating or preventing dysfunctional effects of stress at work. Other perspectives suggest that task characteristics also serve a supportive function. In this study, data from 97 nurses in a paediatric hospital were used to compare the utility of the path-goal theory of leadership, social support theory and substitutes for leadership theory for explaining the impact of leader support on satisfaction and anxiety responses of workers. In addition, the relative impact of leader support and enriched tasks on worker affect was explored. Results suggest that social support theory was able to predict most findings regarding leader support, and that leader support is more important than task to predictions of satisfaction of workers and autonomy is more important to relieving anxiety of workers. The study extends findings about the general value of leader support for managing, but the need to clarify the mechanisms through which the effects occur is emphasized.
