摘要:The aim of this study was to examine a model of Coach-athlete relationship quality based on coaches’ perfectionism and verifying mediating role of forgiveness and controlling behavior. in this study A total of 270 coaches completed four scales: Perfectionism, Forgiveness, Controlling Behavior, and Quality of Relationship. The proposed model was evaluated using structural equation model. Result revealed that coaches’ perfectionism negatively predicted quality relationships with their athletes. Results also revealed that coaches’ forgiveness positively predicted quality relationships but coaches’ controlling behaviors negatively predicted quality relationships toward their athletes. The results of path analysis revealed that the relationship between coaches’ perfectionism and the relationship quality toward their athletes were mediated by forgiveness and controlling behaviors, and Perfectionism was inversely (positive) related to relationship quality with the entry of these mediators. its concluded that relationship between perfectionism and quality relationships is not a simple linear one, but other variables such as forgiveness and coaching behaviors play a mediating role in this relationship.
