Description of intervention(s) / exposure
The Binge Eating eTherapy (BEeT) program consists of ten, one-hour interactive, multi-media sessions developed by clinicians at the InsideOut Institute. BEeT is a Cognitive-Behavioural Therapy (CBT) program with all core components of CBT demonstrated effective in eating disorders, including establishing regular eating according to the “three-hour rule” and self-monitoring, thought challenging and feared food exposure. BEeT is delivered by a live action therapist (i.e. a recorded video of a therapist delivering the key components of the program). Participants will be instructed to complete one x 60 minute module per week across a ten week period. The program also includes interactives exploring key skills in CBT, an inbuilt Food Monitoring, Behaviour Monitoring, Food Planner, Thought Challenge, and Exposure Tool. The program sends a daily SMS to participants’ mobile phones at approximately 9 a.m. as a reminder to record their meals using the Food Diary tool throughout the day. An additional evening SMS is sent at approximately 6 p.m. to participants who had not completed a Food Diary entry for the preceding two days to prompt re-engagement.

Supported self-help BEeT (SSH-BEeT): Participants complete 10 sessions of BEeT in conjunction to 10 weekly x 30 min face-to-face contact sessions with trained clinician across 12 weeks. The clinicians involved will be those employed at NSW Local Health District Community Mental Health Teams or headspace centres. Training of clinicians in the delivery of SSH-BEeT will be provided via an online program and face-to-face training sessions. The weekly contact sessions with clinicians is not intended to serve an additional therapy, rather will involve supporting the participant through their use of BEeT. Accordingly each face-to-face session will have the following structure: general check-in, review of the previous BEeT session and associated homework tasks with particular focus and debrief of specific self-monitoring exercises, review weekly weigh-in and preparation for completion of next BEeT session and associated homework tasks.

Adherence to program content will be captured by the eTherapy system, which provides the rates of participant's completion of program content. Adherence will also be assessed by participant's use of the digital food diary, which is also captured by the eTherapy system. Finally, support session attendance is tracked within RedCap by individual support clinicians, who note participant presence at each scheduled meeting, with the time and date recorded.

Outcomes
Primary outcome [1] 329660 0
Eating Disorder Examination Questionnaire (EDE-Q)
Timepoint [1] 329660 0
Baseline, post-treatment (12 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment). This measure will assist in evaluating the safety of the program, by determining if eating disorder symptoms are significantly worsened by use of the intervention.
Secondary outcome [1] 403336 0
Kessler Psychological Distress Scale (K10)
Timepoint [1] 403336 0
Baseline, post-treatment (12 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment). This measure will assist in evaluating the safety of the intervention by indicating if there is a significant increase in psychological distress at post-assessment.
Secondary outcome [2] 403337 0
The European Quality of Life - 5 dimensions - 5 levels (ED-5D-5L)
Timepoint [2] 403337 0
Baseline, post-treatment (12 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment).
Secondary outcome [3] 403338 0
Three Factor Eating Questionnaire (TFEQ)
Timepoint [3] 403338 0
Baseline, post-treatment (12 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment).
Secondary outcome [4] 403339 0
Adherence: Dropout rates (number of participants who complete the post-treatment assessment) and digital intervention access measures (i.e., log-in rates, number of intervention modules accessed or completed, the frequency of website visits per module, the frequency of access specific tools or features of the program--e.g., self-monitoring tools).
Timepoint [4] 403339 0
This adherence data will be evaluated at the completion of the study to assess adherence/compliance to the eTherapy program week to week, across participant's completion of the eTherapy program.

Statistical methods / analysis
Complete case and multiple imputation analysis will be implemented in accordance with missingness assumptions that fit the data (missing at random vs missing not at random), followed by sensitivity analysis where appropriate. The primary outcome will be the change in objective binge episode frequency (measured by the EDE-Q). Secondary outcomes considered will be changes in all scores on the EDE-Q, K10, EDQOL, TFEQ and BMI.

Linear regression analysis and pairwise comparison will be used to analyse the effectiveness of SSH-BEeT in reducing binge eating symptomology, using the change in pre to post objective binge episodes on the EDE-Q as the primary outcome.

Summary
Brief summary
The study will evaluate the effectiveness of a new interactive online Cognitive Behavioural Therapy program for individuals who experience difficulty with binge eating, named Binge Eating eTherapy or BEeT. BEeT consists of ten, one-hour interactive, multi-media sessions with all core components of CBT demonstrated effective in eating disorders, including establishing regular eating according to the “three-hour rule” and self-monitoring, thought challenging and feared food exposure. The study will examine whether engaging with BEeT results in a significant decrease in individuals' binge eating in those with binge-eating disorder.
