Although research has examined the antecedents of prosocial and antisocial behaviors in sport, little is known about the potential consequences of this behavior for the recipient. We examined: (a) whether teammate prosocial and antisocial behavior predict athletes’ effort and performance during a match and the mediating role of enjoyment and anger, and (b) whether this behavior predicts the commitment to play for one’s team and the mediating role of enjoyment and performance. 298 basketball players completed a multi-section questionnaire after a competitive match. Prosocial teammate behavior predicted effort and performance directly and indirectly through enjoyment; it also predicted commitment directly and indirectly through enjoyment and performance. Antisocial teammate behavior positively predicted anger and negatively predicted effort and performance. Anger and performance mediated the effects of antisocial teammate behavior on effort and commitment, respectively. Our findings demonstrate the importance of acting prosocially and not acting antisocially toward one’s teammates in order to enhance enjoyment, effort, performance and commitment.
