group cohesion
the unity or solidarity of a group, including the integration of the group for both social and task-related purposes. Group cohesion is indicated by the strength of the bonds that link members to the group as a whole, the sense of belongingness and community within the group, the feelings of attraction for specific group members and the group itself as experienced by individuals, and the degree to which members coordinate their efforts to achieve goals, although these factors are neither necessary nor sufficient conditions for cohesion. In many cases, the higher the cohesion, the stronger the members’ motivation to adhere to the group’s standards and the more stable the group’s membership. Group cohesion frequently is considered essential to effective group therapy. Also called group cohesiveness. See also esprit de corps; group solidarity.
