Age differences between leader and followers as a moderator of the relationship between transformational leadership and team performance

In a field study of 49 R&D teams in the pharmaceutical industry, the age difference between the team leader and the team members was examined as a moderator of the relationship between transformational leadership and team supervisors' longitudinal ratings of team performance. Data collected from 285 team members and 21 team supervisors showed that this relationship was positive when the leader was older than the other team members, but non-significant when the leader's age was closer to the mean age of the team members. This finding broadens the still fragmentary knowledge of the conditions under which transformational leadership is likely to have more or less positive effects on team performance.
