When team members' values differ: The moderating role of team leadership

Integrating theory and research on values, diversity, situational strength, and team leadership, we proposed that team leadership moderates the effects of values diversity on team conflict. In a longitudinal survey study of national service teams, we found significant, but opposite, moderating effects of task-focused and person-focused leadership. As predicted, task-focused leadership attenuated the diversity-conflict relationship, while person-focused leadership exacerbated the diversity-conflict relationship. More specifically, task-focused leadership decreased the relationship between work ethic diversity and team conflict. Person-focused leadership increased the relationship between traditionalism diversity and team conflict. Team conflict mediated the effects of the interactions of leadership and values diversity on team effectiveness.
