The effect of grit on psychological well-being in collegiate athletes: the moderating role of social support

Introduction This study examined the association between grit and psychological well-being among collegiate athletes and investigated whether social support from coaches and teammates moderates this relationship. Methods A total of 342 Korean collegiate athletes completed validated measures of grit, perceived social support, and Ryff's psychological well-being dimensions. PROCESS Macro Models 1 and 2 were used to test direct and moderating effects. Results Grit significantly predicted autonomy, environmental mastery, personal growth, and positive relations. Coach support attenuated grit's positive effects in several domains, whereas teammate support strengthened grit's influence, particularly for interpersonal well-being. Discussion These findings highlight the interplay between personal traits and environmental factors in athletes' mental health. Fostering grit within supportive sport environments may enhance collegiate athletes' psychological well-being.
