In recent years, organizations have increasingly transitioned to using work team configurations (Cohen & Bailey, 1997). Despite this trend, researchers still know little about how team composition variables impact the processes and outcomes of teams (Barrick et al., 1998). This study sought to address this gap by considering how state affect impacted indicators of team processes (social and task cohesion) and group effectiveness (performance, viability, and group task satisfaction). In addition, this study sought to determine if one method of operationalizing team composition (mean, minimum, or maximum) was most informative. It found that mean PA was positively related to team performance, maximum PA was negatively related to team performance, minimum NA and mean NA were positively related to team performance, and mean PA was positively related to group task satisfaction. Finally, the present investigation attempted to explore the relations between different effectiveness variables. It found that team viability was positively related to group task satisfaction and group task satisfaction was positively related to team viability.
