Description of intervention(s) / exposure
The SkillED Program is an online self-help education program. It is aimed for users 14 years+ who are experiencing subclinical or clinical symptoms of an eating disorder. The SkillED program draws upon the key principles of cognitive behaviour therapy and is therefore in accordance with the Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of eating disorders (Hay et al., 2014).  It offers 11 modules including 5 core modules of evidence-based psychoeducation and skills, such as motivation, self-monitoring, disordered and regular eating, and 6 optional modules selected by participants including role of cognition, emotions, external triggers, dietary rules, body image and relapse prevention. Participants will be given one-week to complete each module. Participants will have access to the SkillED Program up for to 26 weeks from initial enrolment (depending on their selection of optional modules).

Users of SkillED will be required to complete 5 core modules before being able to access the optional 6 modules which they can self-select. The additional six modules are optional and can be repeated as often as desired within the access period. Each module is approximately 40-50 minutes long and include a series of short videos as well as interactive activities and quizzes. Participants will be asked to select which optional modules they would like to complete at the beginning of the program, and also to reconfirm their selection of optional modules after completing the core modules so that, if desired, they can adjust their choices to better suit to their learning needs. An adjunct digital self-monitoring tool is available as part of the SkillED program (i.e., treatment tools that will enable participants to self-monitor their activities during the program e.g., Food Monitoring, Behaviour Monitoring, Food Planner, Thought Challenge, and Exposure Tool).

To assess engagement with the SkillED program, we will collect usage data. When participants use the SkillED Program, the digital platform itself will automatically record usage patterns.

Statistical methods / analysis
Descriptive statistics will be conducted for sociodemographic and psychological characteristics, as well as usage analytics and feedback to evaluate program acceptability and feasibility. Characteristics of those who complete all core modules will be compared to with those who complete additional optional modules. Characteristics of completers and non-completers will also be compared using chi-square tests of independence (categorical variables) and independent samples t-tests (numeric variables).

Generalised linear mixed model (GLMM) will be used to determine changes from pre- to post-treatment on all outcome variables, controlling for baseline differences between dropouts and completers. Significant predictors of treatment response will be entered into a multivariate model to identify unique effects. Two analyses will be conducted for all outcome measures: (1) an intent-to-treat (ITT) analysis with all program starters and (2) a sensitivity analysis for core module completers only. For sensitivity analyses, repeated measures ANOVAs will used to test the effect of program completion over time on all outcome variables, with Bonferroni-adjusted confidence intervals for pairwise comparisons [baseline (T1) vs., post-core module completion (T3), T1 vs. 3-month follow-up (T6), T3 vs. T5]. Additionally, paired sample t-tests will be used to further explore program completion effects on subscales of outcome variables and self-reported knowledge, willingness and confidence assessed at T2, with Cohen’s D measure of effect size calculated for all significant results.
