In an attempt to capture some of the complex social interactions in sports, which undoubtedly leads to different socialisation experiences, an additional purpose of this study was to examine possible relations between children and adolescent athletes’ dispositional goal orientations (task and ego), perceived motivational climate in sports, perceived sport-specific competence, perceived prosocial coaching and presumptive psychosocial effect variables.
