Abstract: Collective efficacy represents a group’s shared belief in their conjoint capabilities to organize and execute the courses of action required to produce given levels of attainments. There are mainly three methods of assessing collective efficacy: an aggregate of self-efficacy perceptions, an aggregate of individual perceptions of collective efficacy, and group discussion. Scholars have found that collective efficacy can effectively predict performance and some other work-related attitudinal and behavioral variables. However, too high collective efficacy can also produce negative effects. The antecedents of collective efficacy include the factors both within and between groups (e.g. group size and inter-group competition), and intervening methods such as goal-setting training can significantly increase collective efficacy as well. At last, the paper pointed out five prospects for the future research
