Abstract
BackgroundBinge eating disorder is characterized by recurrent episodes of binge eating accompanied by a sense of lack of control. Of the different treatments available, Cognitive Behavioral Therapy-Enhanced and guided self-help treatment are recommended. As online treatment offers several additional advantages, we have developed a CBT-Enhanced online guided self-help intervention. The aim of this study is to determine whether this intervention reduces eating disorder pathology and increases the amount of binge free days in adults classified with binge eating disorder or other specified feeding or eating disorder- binge eating disorder, compared to an untreated waiting list condition. The experimental condition is hypothesized to be superior to the waiting list condition.MethodsThe efficacy of an online guided self-help intervention for binge eating disorder will be assessed by conducting a randomized controlled trial. The trial will target adult individuals classified with binge eating disorder or other specified feeding or eating disorder- binge eating disorder with a body mass index between 19.5 and 40, referred to an eating disorder treatment center. Dual arm allotment will be performed in a 1:1 ratio stratified for BMI above or below 30. Randomization will be blinded to the online intervention (n = 90), or to the control waiting list condition (n = 90). Assessors will be blinded and assessments will be administered at baseline, week 5, at end-of-treatment, and at 12 and 24 weeks follow-up. Primary outcome will be eating disorder pathology, operationalized as number of days on which binge eating occurred between the two conditions during the period of the intervention. Secondary outcome measures will be differences in other eating disorder pathology, clinical impairment and in quality of life, while therapeutic alliance, demographic characteristics and followed treatment module will serve as effect moderators. Several types of costs will be assessed.DiscussionThis paper presents an online guided self-help Cognitive Behavioral Therapy- Enhanced study protocol for individuals classified with binge eating disorder or other specified feeding or eating disorder. Efficacy will be examined through a Randomized Controlled Trial.Trial registrationThe study protocol is registered with the Netherlands Trial Registry NTR (NTR 7994) since 6 September 2019.

The primary aim of this study is to examine the efficacy of online guided self-help (GSH) Cognitive Behavioral Therapy (CBT)-E with regard to eating disorder pathology, operationalized as difference in the number of binge-free days among men and women classified with Binge eating disorder (BED) and/ or Other specified feeding or eating disorder (OSFED) BED after treatment compared to a waiting list control group
This paper presents a study protocol of an randomized controlled trial (RCT) on the efficacy of online GSH Guided Self-Help Cognitive Behavioral Therapy- Enhanced (CBT-E) treatment for individuals suffering from BED and/or OSFED BED
Summary
Binge eating disorder is characterized by recurrent episodes of binge eating accompanied by a sense of lack of control. As online treatment offers several additional advantages, we have developed a CBT-Enhanced online guided self-help intervention. Binge eating disorder (BED) is characterized by recurrent episodes of binge eating accompanied by a sense of lack of control [5]. According to Fairburn, developer of CBT-Enhanced, [11, 12], CBT-Enhanced treatment leads to a recovery rate of 50–65% amongst the individuals with an eating disorder. As, according to the stepped care principle, CBT-Enhanced could be too intensive for individuals suffering from BED or OSFED BED, international guidelines have recently recommended guided self-help treatment as first step for individuals suffering from BED [9]. An online guided self-help version of CBT-Enhanced (GSH CBTE) follows all recommended evidence-based guidelines for individuals suffering from BED [9]
