This study uses regulatory focus theory to take a holistic perspective on employee coaching. The contrasting effects of facilitative versus pressure-based coaching on changes in team effectiveness were examined over a 54-month period of time. Results of growth curve analysis on a sample of 714 managers and their teams indicated that facilitative and pressure-based coaching had opposing direct and indirect effects on long-term changes in team performance, with team commitment playing a critical role in this process. Specifically, facilitative coaching positively influenced team commitment and, in turn, team effectiveness. In contrast, pressure-based coaching hindered team functioning by negatively influencing team commitment through heightened levels of tension within the team. Limitations and areas for future research are discussed.
