Cohesion in group therapy: A meta-analysis.

Burlingame, Gary M., McClendon, Debra Theobald, Yang, Chongming·2018·Psychotherapy

Abstract

Cohesion is the most popular of the relationship constructs in the group therapy literature. This article reviews common definitions of cohesion, the most frequently studied measures, and a measure that may clarify group relations using two latent factors (quality and structure) to explain common variance among frequently used group relationship instruments. We present the results of a meta-analysis examining the relation between group cohesion and treatment outcome in 55 studies. Results indicate that the weighted aggregate correlation between cohesion and treatment outcome was statistically significant, r = .26, z = 6.54 (p < .01), reflecting a moderate effect size (d = .56). Heterogeneity of effect sizes was significant (Q = 260.84, df = 54, p < .001) and high (I2 = 79.3%), supporting moderator analyses. Six moderator variables were found to significantly predict the magnitude of the cohesion-outcome association (type of outcome measure, leader interventions to increase cohesion, theoretical orientation, type of group, emphasis on group interaction, and dose or number of group sessions). Patient contributions, diversity considerations, and evidence-based therapeutic practices are highlighted. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Offering a therapeutic treatment program in a group, provided that the group dynamics are used adequately, has been found to strengthen the result of the treatment.

    “Offering a therapeutic treatment program in a group, provided that the group dynamics are used adequately, has been found to strengthen the result of the treatment (Burlingame et al., 2018).”
  • Variation in therapists' ability to form an effective alliance and variation in group cohesion have been proposed as common factors that may underlie these effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
