Interpersonal learning is associated with improved self-esteem in group psychotherapy for women with binge eating disorder.

Yalom and Leszcz (2005) indicated that interpersonal learning is a key therapeutic factor in group psychotherapy. In this study, we conceptualized interpersonal learning as the convergence over time between an individual's and the group's perception of the individual's cohesion to the group. First, we developed parallel measures of: (a) an individual's self-rated cohesion to the group (Cohesion Questionnaire-Individual Version [CQ-I]), and (b) the group's rating of the individual's cohesion to the group (CQ-G) based on the original Cohesion Questionnaire (CQ; Piper, Marache, Lacroix, Richardsen, & Jones, 1983).
