Group cohesion: A new multidimensional model

Based upon a careful perusal of all major theoretical reviews and most available controlled, empirical studies from the last 30 years, a five factor model of group cohesion is proposed. These factors are: attraction and bonding; support and caring; listening and empathy; self-disclosure and feedback; and process performance and goal attainment. To understand more fully the complex phenomenon of group cohesion, certain preconditions to the cohesive therapy group must be considered. The most significant of these are: selection of suitable participants; a balanced composition of the group; and effective orientation, training, and contracting. Important early group conditions are: resolving conflict and rebellion; constructive norming and culture building; and reducing avoidance and defensiveness. This new, generic, multidimensional model of group cohesion should prove of great value both to the clinician and the researcher in the group psychotherapy field and related areas.The author is indebted to the following colleagues for constructive criticisms of earlier versions of this report: S.
