Uniting Couples in the Treatment of Binge-Eating Disorder

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.
