Beyond Cohesiveness: Reconceptualizing the Link Between Group Processes and Outcomes in Group Psychotherapy

In: Small group research: an international journal of theory, investigation, and application, Band 38, Heft 5, S. 567-592

Abstract

Despite a general consensus that cohesiveness promotes positive outcomes in group psychotherapy, the empirical evidence for this notion is limited. In this article the literature on group cohesiveness and its relation to clinical outcomes is reviewed. Three interrelated problems with this literature are highlighted: A lack of consensus as to how to conceptualize cohesiveness, inconsistent measurements of cohesiveness, and lack of attention to possible mediators of the cohesiveness-outcome relationship. The authors argue that the term cohesiveness is too vague and amorphous to be useful as a unitary construct and that the field could benefit by identifying more specific group processes that facilitate—or impede—clinical outcomes. They review social psychological research on group processes, and discuss how three constructs— group identification, independence, and homogeneity—might be applied to the clinical literature. Furthermore, in an attempt to stimulate a closer examination of mediational paths in the literature on group psychotherapy, they discuss possible mechanisms through which group processes affect clinical outcomes.
