Description of intervention(s) / exposure
The Brief Binge Eating eTherapy (BEeT) program consists of four, one-hour interactive, multi-media sessions developed by clinicians at the InsideOut Institute. Brief BEeT is a Cognitive-Behavioural Therapy (CBT) program with the core behavioural components of CBT demonstrated effective in eating disorders, including establishing regular eating according to the “three-hour rule” and self-monitoring. 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 six week period. The program also includes interactives exploring key skills in CBT, an inbuilt Food Monitoring, Behaviour Monitoring, and Food Planner. 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.

Brief Supported self-help BEeT (Brief SSH-BEeT): Participants complete 4 sessions of BEeT in conjunction to 5 weekly x 30 min face-to-face contact sessions with trained clinician across 6 weeks. The clinicians involved will be those employed at the University of Sydney at the InsideOut Institute for Eating Disorders. Training of clinicians in the delivery of Brief 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 Brief 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] 329885 0
Eating Disorder Examination Questionnaire (EDE-Q)
Timepoint [1] 329885 0
Baseline, post-treatment (6 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] 404171 0
Kessler Psychological Distress Scale (K10)
Timepoint [1] 404171 0
Baseline, post-treatment (6 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] 404172 0
The European Quality of Life - 5 dimensions - 5 levels (ED-5D-5L)
Timepoint [2] 404172 0
Baseline, post-treatment (6 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment).
Secondary outcome [3] 404173 0
Three Factor Eating Questionnaire (TFEQ)
Timepoint [3] 404173 0
Baseline, post-treatment (6 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment).
Secondary outcome [4] 404174 0
Adherence: Dropout rates (number of participants who complete the post-treatment assessment, assessed via audit of study records in RedCap where the pre/post-treatment assessment data is stored) 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] 404174 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.
Secondary outcome [5] 405043 0
An item of the EDE-Q (see primary outcome measure) also requests participant's current BMI, which will be used two-fold: as a confirmatory safety measure to ensure adequate BMI for participation as per inclusion criteria, and as an secondary outcome measure to assess any significant change in BMI across the course of the intervention.
Timepoint [5] 405043 0
Baseline, post-treatment (6 weeks after intervention commencement) and follow-up (12 weeks after post-treatment assessment).

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 Brief 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, brief interactive online Cognitive Behavioural Therapy program for individuals who experience difficulty with binge eating, named Brief Binge Eating eTherapy or Brief BEeT. Brief BEeT consists of four, one-hour interactive, multi-media sessions with the behavioural components of CBT demonstrated effective in eating disorders, including establishing regular eating according to the “three-hour rule” and self-monitoring. The study will examine whether engaging with Brief BEeT results in a significant decrease in individuals' binge eating in those with bulimia nervosa or binge-eating disorder.
