Leading well: Challenges to researching leadership in occupational health psychology - and some ways forward

Studies on the effects of leadership in occupational health psychology build on the assumption that leaders influence their followers' health and well-being. Although this assumption has received support, this introductory paper to a special issue of Work & Stress on leadership argues that a number of questions regarding leadership and follower health and well-being remain unanswered. We identify four issues that we argue warrant further attention. First, what is "good" leadership? Particular leadership types are associated with increases in employee performance, but since this will involve higher effort expenditure, adverse outcomes for employee health are to be expected. Although many types of leadership are associated with favourable outcomes, we still need to identify the leadership characteristics can be identified that account for these positive outcomes. Second, how can good leadership be promoted? There is a need to develop interventions that are effective in promoting desirable leadership styles. Third, what are the inter-mediate and long-term effects of leadership on follower health? Finally, we need to understand the boundary conditions for good leadership, including the resources available to leaders. Based on these considerations, we conclude that further research is needed to fully understand the effects of leadership on employee health and well-being.
