This study evaluated the interpersonal model of binge eating and associated psychopathology over the course and 4-month follow up of two psychotherapy treatments (Cognitive Behavioral Therapy and Interpersonal Psychotherapy), and examined if treatment effects emerged. The model posits that interpersonal problems lead to negative affect which results in binge eating. The model was tested using data from a clinical sample of 159 women and men with binge eating disorder (BED) who were participants in a comparative psychotherapy treatment trial (Wilfley et al., 2002). Analyses examined a series of longitudinal mediation analyses examining regression pathways, direct effects, and indirect effects. The results did not provide support that psychotherapy treatment addresses the mechanisms of the interpersonal model of binge eating as theoretically proposed. Findings suggest that reductions in interpersonal problems and negative affect over the course of treatment did not differ between CBT and IPT. It is possible that the mechanisms of the interpersonal model of binge eating change on a more momentary level over the course of treatment, and therefore, the constructs in the current study were not measured to be reflective of the potential momentary relations of the theoretical model. Future research should use ecological momentary assessment to explore the interpersonal model of binge eating on a momentary level over the course of psychotherapy treatment.
