Organizational citizenship behavior and team performance: A longitudinal field study.

This longitudinal field study assesses relationships among organizational citizenship behavior (OCB), task interdependence, and performance in work teams. As predicted, measures of team OCB - collected from both team members and customers - correlated positively with concurrent team performance and subsequent performance - using criterion data from both team leaders and team customers. Task interdependence moderated the positive relationship of team OCB with subsequent team performance. The results, based on multi-source measures of both team OCB and team performance, collected on two occasions, extend the current research on OCB from the individual to the team level.
