Modeling cohesion change in group counseling: The role of client characteristics, group variables, and leader behaviors.

Despite continued empirical support for a relationship between group cohesion and therapeutic gain, few studies have attempted to examine predictors of cohesion during the life of counseling groups. The present investigation explored the impact of client variables, group characteristics, and first-session leader behaviors on changes in cohesion across time. Participants were 128 volunteer clients and 14 group therapists participating in 23 separate 8-week-long counseling groups. Results of latent growth curve (LGC) analysis indicated that a piecewise, linear-quadratic model best fit the data at the individual level, while a simplified linear model best fit the data at the group level. Overall, individual differences accounted for 80-97% of the total variance in cohesion intercept and slope terms, with the included covariates explaining 9-39% of this variation. Significant individual-level covariates were gender and anxious and avoidant attachment. The only significant group-level predictor was an interaction effect between leadership behaviors in the first session. Specifically, when leaders performed a high number of structuring behaviors in the absence of facilitating emotional sharing, cohesion was lower at the end of the first session. Limitations, areas of future research, and implications for the theory and practice of brief group counseling are discussed.
