Abstract
The purpose of this present study is to gauge the usefulness of head coaches’ transformational leadership in predicting followers’ individual, objectively measured performance development over time. The sample encompassed data on 22 coaches and 200 players from German professional basketball. Each player's performance was captured for approximately 20 subsequent games resulting in a sample of 3,905 measurement points. Our analyses revealed significant effects from transformational leadership facets of Articulating a Vision, Fostering the Acceptance of Group Goals, and Providing Individualized Consideration on the development of players’ performance over time.
