Background: Patients with Binge Eating Disorder (BED) and obesity experience distressing relationships, which could trigger negative affect and over-eating. To date no studies compared the interpersonal profiles and prototypicality of both groups using the Interpersonal Circumplex.Method: A sample of 177 patients with BED (mean age: 41.0 +/- 12.5 years; 11.3% males), 321 obese non-BED adults (mean age: 44.5 +/- 13.4 years; 28% males), and 108 normal weight adults (mean age: 37.3 +/- 9.6 years; 52.77% males) completed the Inventory of Interpersonal Problems (IIP-32), and scales of binge eating and psychological distress at one time-point.Results: Compared to normal weight and obese participants, those with BED reported higher levels of interpersonal problems on all circumplex dimensions, except for Vindictive, with small to medium effects. All groups had highly prototypical profiles. Both obese and normal weight adults had very similar interpersonal profiles characterized by predominant friendly-dominant themes. On the contrary, those with BED had predominant friendly-submissive themes. Patients with BED reported significantly higher levels of psychological distress and binge eating severity, compared to the other two groups. Greater Domineering, Cold, Socially Inhibited and Non-Assertive scale scores, and lower Vindictive scale scores significantly predicted higher binge eating and psychological distress, regardless of group membership.Discussion: Findings lend support to an interpersonal model of binge eating and to the presence of qualitative differences between patients with obesity and BED. Finally, results suggest some strategies for the clinical management of BED focused on non-assertion and problems with experiences and expression of anger. (C) 2018 Elsevier Inc. All rights reserved.
