Summary

The purpose of this study is to test the feasibility, acceptability, and preliminary effectiveness of a novel couple-based intervention for binge-eating disorder (BED) relative to an established evidence-based individual treatment (cognitive-behavioral therapy-enhanced; CBT-E) in a community clinic setting.

Detailed description

Clinicians' options for BED treatment are inadequate. Treatments for BED have demonstrated efficacy in controlled settings with specialist therapists and expert supervision, but much less in known about the effectiveness of BED interventions and whether the transition of evidence-based treatments to the community results in poorer outcomes. UNITE activates a key resource by incorporating an important part of the patient's social environment (the partner) into treatment. The investigators hypothesize that UNITE will show preliminary evidence of being superior to CBT-E in achieving binge abstinence via engaging ED-related relationship targets, including improved (a) communication around the disorder, (b) disorder-specific interpersonal problem-solving/ behavioral change skills, and (c) partner-assisted emotion regulation. The investigators will assess targeted relationship domains with observational and speech prosody measures during clinic interactions and self-reports reflecting experiences outside the clinic. Because the couple is learning how to work together to address BED, the investigators hypothesize that maintenance of gains will show evidence consistent with superiority in UNITE.

Conditions

• Binge-Eating Disorder

Interventions

Type	Name	Description
BEHAVIORAL	UNITE	UNITE includes three stages: early treatment (psychoeducation and understanding the couple's experience of BED within the relationship); mid-treatment (effective communication, interpersonal problem-solving, and emotion regulation skills), and late treatment (relapse prevention). Additional relevant topics may be covered including body image, weight stigma, weight and health concerns, and intimacy and sexuality issues.
BEHAVIORAL	CBT-E	CBT-E includes four stages: an introductory stage (psychoeducation, normalization of eating patterns, and symptom self-monitoring); a second, brief stage (review progress and formulate plans for the subsequent treatment phase); a third stage (elimination of dieting, reducing shape checking and avoidance behaviors, educating about mood tolerance, and targeting overevaluation of shape and weight); and the fourth stage (maintaining progress and minimizing relapse risk).
