A cross-level moderating effect of team trust on the relationship between transformational leadership and cohesion.

We draw on the concept of the shared mental model to explain the cross-level direct and moderating effects of team trust on the relationship between coach transformational leadership and cohesion. Using hierarchical linear modelling, we analysed 597 national level high school and university volleyball players to test our research model. Our results revealed that, (a) at the individual level, coach transformational leadership has a positive effect on athletes' perceptions on cohesion and (b) team trust, a group-level construct, is positively related to social cohesion and moderates the coach transformational leadership-cohesion relationship. The moderating effect demonstrates that the positive effect of coach transformational leadership on cohesion could be enhanced when high levels of team trust are shared within the group. Implications for coach education and sport psychology in terms of theory and research are discussed.
