Satisfaction with group work is an important and frequently studied phenomenon that often determines whether a new tool, technology, or method is successfully implemented in an organization. We report on a longitudinal study of small groups which used regression to model how satisfaction with the process, outcome, and group evolves over multiple sessions as a function of performance measures and prior satisfaction levels. The results indicated that current performance contributed less to satisfaction as the study proceeded and by the end of the study period satisfaction with the process and outcomes were determined almost exclusively by prior satisfaction levels. In general, the conclusions were dependent on the point in time at which the analysis was conducted and on the object of satisfaction under consideration. The results highlight the importance of longitudinal studies, rather than one-shot approaches, for understanding individual satisfaction with group work.
