The role of communication and cohesion in reducing social loafing in group projects

Increasing Interdependence in Online Communities

Collective efficacy is the shared belief that a group can perform the task at hand as a whole. When collective efficacy is high, task cohesion also increases. 

Collective Efficacy in Online Communities

Collective Task Value involves an individual's perception of the overall group's value of the task.
