This study aims to develop and evaluate the efficacy of a behavioral weight loss treatment approach for individuals with binge eating disorder to both reduce their binge eating behaviors and lose weight.
In the current study, we propose to (a) compare the efficacy of an acceptance-based behavioral treatment (ABBT) that targets both binge eating and weight loss in patients with binge eating disorder (BED) to a Standard Behavioral Weight Loss Treatment (SBT), (b) evaluate the extent to which ABBT and SBT target shared maintenance factors for binge eating and overeating episodes, and (c) assess whether treatment efficacy is moderated by baseline values of constructs targeted in ABBT. Our study will be the first to evaluate an ABBT for BED designed to 1) address maintenance factors that give rise to both binge eating episodes and overeating episodes without loss of control and 2) increase adherence to BWL prescriptions.

ABBT group therapy incorporates standard behavioral and acceptance-based strategies and was adapted to meet suit the unique needs of BED.
SBT group therapy will be adapted from the gold-standard standard behavioral therapy manuals used from previous weight loss studies.

Weight Loss
Between-group changes in percent weight loss from baseline 1 month, 3 months, and 6 months into the study, at post-treatment (1 year after baseline) and at the one year follow-up assessment (2 years after the baseline).
Time frame: Changes from baseline assessment (before beginning treatment), to post-treatment assessment (1 year after baseline assessment), to follow-up assessment (2 years after baseline assessment)
Eating Disorder Examination Questionnaire
The Eating Disorder Examination Questionnaire measures eating pathology. The EDE-Q yields four subscale scores: Restraint, Eating Concern, Shape Concern, and Weight Concern. The possible score range for each subscale is 0 to 6. The total score may also be reported (determined by averaging the subscale scores); the score range for the total score is also 0 to 6. For subscale scores and total score, higher scores indicate more severe pathology. The restraint sub-scale of the EDE-Q will be used to assess utilization of skills related to reducing dietary restraint. Assessing changes in EDE Global score.
Time frame: Baseline, Post-Treatment (1 year after baseline), and 1 Year Follow-Up (2 years after baseline)
