“…Within the coach–athlete relationship, interpersonal behaviors that display responsiveness (openness), readiness (willingness), easiness (acceptance), and friendliness (compassion, warmth) are key for both individual-related factors (e.g., vitality, satisfaction, positive affect) and group-related processes (e.g., team cohesion, collective efficacy). Importantly, such interpersonal complementary and collaborative behaviors can shape a positive social environment that is both healthy and psychologically safe (Jowett & Wachsmuth, 2020) and provide a sound platform for building high-performing teams (Edmondson, 1999; Edmondson & Lei, 2014).
