Abstract: Objective: To discuss the relations between teammate conflict, organizational citizenship behavior (OCB) and satisfaction. Methods: The study chose 336 U15 high-level male basketball athletes as samples and tested them using teammate conflict scale, athlete OBC scale and athlete satisfaction scale. Results: Team conflict has powerful explanation for OCB (R²=0.042, 0.166, 0.195, 0.287,P<0.01), meanwhile it has significant explanatory power for athletes satisfaction (R²=0.108, 0.149,P<0.001) and the two dimensions of satisfaction, namely the dimension of individual performance and the dimension of team performance (R²=0.108, 0.149,P<0.001). When team conflict and OCB were used together to predict athlete’s satisfaction, the influence of teammate conflict on the two dimensions of satisfaction was significantly decreased. Among them, the individual performance was still significant (ΔR²=0.024,P<0.05), while the team performance was not significant any more (ΔR²=0.008,P>0.05). Conclusion: Team conflict was not conducive to the improvement of athlete’s OBC and satisfaction, but OBC has a positive effect on satisfaction improvement, and played a mediation role between team conflict and satisfaction.
