Is there an optimal level of positive and negative feedback in group therapy? A response surface analysis.

Interpersonal feedback is an important process in group therapy. Feedback can be both positive and negative, and group researchers have noted the importance of both positive and negative feedback in fostering cohesive groups and evoking behavioral change (Yalom & Leszcz, 2005). However, there is a paucity of research examining the amount and valence (i.e., positive and negative) of interpersonal feedback on group therapy process and outcomes. Therefore, this study tested the proposition that congruent and high levels of members’ perceptions of positive and negative feedback was optimal for member’s perceptions of cohesion and improvement in group therapy. Data for this study consisted of 168 members across 43 interpersonal process therapy groups. Polynomial regression and response surface analysis revealed that members’ perceptions of congruent and high levels of positive and negative interpersonal feedback were positively associated with members’ perceptions of group cohesion and improvement. In addition, members’ perceptions of discrepant high positive feedback and low negative feedback were positively associated with members’ perceptions of group cohesion and improvement. These findings suggest that members’ perceptions of balanced and high amounts of positive and negative feedback, as well as discrepant high positive feedback and low negative feedback, are optimal in group therapy. Group leaders should attend to the amount and proportion of positive and nega...
