Cohesiveness in groups: a concept in search of a definition.

Cohesiveness in groups has been studied intensively since the 1950s. It is viewed as a central property of all groups and a "curative factor" in therapy groups. Literature on group work in nursing incorporates discussion of group cohesiveness. Its "positive valence" has invited broad application without critical examination of its meanings and limitations. Progress in thinking about cohesiveness in groups, as well as the lack of generally accepted theoretical and operational definitions, suggests the relevance of a reexamination of the concept with a view toward recognizing its limitations or moving toward greater specification of the meaning and improved measurement of the concept.
