We respond to the call to investigate antecedents of coach transformational leadership and their indirect effects on athlete outcomes. We propose that coach extraversion as an antecedent of coach transformational leadership can indirectly impact follower cohesion and satisfaction. Building on this mediation model, we assert that educational environment (i.e., high school and university) may serve as a first-stage moderator between coach extraversion and transformational leadership. We used 48 coaches and their 570 athletes from competitive high school and university basketball teams to test this moderated mediation model. Our results indicate that coach extraversion indirectly impacts athlete cohesion and satisfaction via transformational leadership. Moreover, the indirect effects of coach extraversion on athlete outcomes via coach transformational leadership is conditionally significant only when coaches and athletes are in universities but not in high schools. Our findings highlight the importance of educational environment in determining the association between coach personality and leadership perception. Implications for research and practice are discussed.
