This study examined the sources of group efficacy and the joint roles of group efficacy and gender diversity on the relationship between group efficacy and group outcomes. We used 45 project groups (260 undergraduate students) designed to complete two in-class group projects. We found that past performance and self-efficacy were both positively related to group efficacy. Further,the interaction of gender diversity and group efficacy was positively related to group effectiveness (project grade and group cohesion). Specifically, mixed gender groups facilitated the relationship between group efficacy and group effectiveness. Implications of the study are discussed.
