This study examined the direct and interactive relationships of interdependence (task and reward) and preference for group work on the satisfaction and performance of group members. Hypotheses were tested among a sample of task-performing group members over a four-month period (N's = 328-432). Consistent with a "community of fate" perspective, hierarchical regressions revealed that interdependence (task and reward) and preference for group work were positively related to group-member satisfaction. Consistent with "supplies-values fit" framework, the interaction of task interdependence and preference for group work was significantly related to group-member performance. Implications for the design of group tasks, the effects of group-member preferences, and the prediction of individual satisfaction and performance in group contexts are discussed.
