Group efficacy is an emerging construct that has great potential for small group performance. Several studies have linked group efficacy to increased productivity. However, few studies have examined the relationship between group efficacy and other group variables that contribute to long-term group productivity. This study addresses the relationship between group efficacy and other group variables. Specifically, it examines the relationships between group efficacy and group viability, personal learning and development, satisfaction with leadership opportunities, and the ability to work independently within the group. Results suggest that group efficacy has a beneficial effect on group dynamics and overall group effectiveness. Groups with higher levels of group efficacy rated higher on group viability, learning and self-development while within the group, and opportunities for individual autonomy. Group efficacy was not found to have an impact on satisfaction with leadership opportunities. Implications of these findings and suggestions for future research are addressed.
