Interpersonal psychological well-being among coach-athlete-sport psychology practitioner triads.

The importance of psychological well-being (PWB) is widely acknowledged in global policy and has important ramifications for health, performance, and engagement among sport performers.

We aimed to explore the interpersonal antecedents, transfer mechanisms, and outcomes of PWB within and among athletes, coaches, and sport psychology practitioners (SPPs).
