In the current study, the authors examine how leadership within a team predicts levels of group potency and group performance over time. The authors predict that groups that rated themselves high on transformational team leadership behaviors soon after the groups were formed would see themselves as being more potent over time and also would achieve a higher level of group performance. These predictions were confirmed. The implications of the current study for further research on leadership within teams are discussed.
