This is a follow-up study from ACTRN12618001156279. We are expanding the research to include 13-25 year-old females and males, rather than 18-25 year-old women in the first trial. We are also investigating if rate of program completion impacts on outcomes.

Description of intervention(s) / exposure
Media Smart-Targeted (MST) is a 9-module mobile website designed to reduce eating disorder risk (ED: e.g., anorexia nervosa, bulimia nervosa, binge eating disorder). The program includes content targeting: media internalisation, social media usage, emotion regulation, and helpful eating habits. Examples of learning content includes: find online advertisements that stereotype men, women and lifestyle then make a virtual poster to ‘send-up’ these stereotypes; video clips showing various techniques used pre and post photography to manipulate images presented in media; strategies for reducing appearance checking and managing emotions when feeling distressed (e.g., 3-minute breathing space, distress tolerance strategies); and, activities aimed at eliciting personal values then focusing on short and long-term goal setting and the plans needed to reach these.

MST is an adapted form of the school-based program Media Smart that has shown positive effects in young-adolescents.

MST is a self-guided website (i.e., no moderator involved). Participants cannot see other participants responses. Participants are asked to complete homework tasks after each module (e.g., experiment with reducing social media use). Each module takes approximately 20 minutes to complete and involves watching educational videos, reading relevant information and typing answers to questions.

In this RCT, there will be two versions of MST: 1) weekly release of modules as per previous research (i.e., 9 weeks in duration), and 2) user can choose their rate of program completion (i.e., number of weeks not determined but it is assumed that this will generally be less than 9 weeks). Module adherence will be monitored by website diagnostic data that will record dates, time and duration of logins.

Comparator / control treatment
The control group will receive a single email with 10 tips on positive body image in an email. This is the same control intervention that we used in the previous RCT. Thus there will be 3 groups in total: MST- Standard (weekly release of modules); MST-Flexible (user chooses own pace); and control group.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Computer randomisation will be used, thus the researchers will not be involved in this process.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The website will used simple randomisation, stratified by age, sex, and eating disorder diagnosis.

Other design features
All aspects of the research will be conducted online. Participants will complete baseline measures and following this will be automatically randomised to one of the 3 study conditions (assuming exclusion criteria are not met).

Type of endpoint(s)
Efficacy
Statistical methods / analysis
The primary analyses of comparison between groups on changes in disordered eating (and all continuous variables), will be based upon linear mixed-effects models (LMM) with random intercepts. Models will include fixed effects for group (MST-Flexible, MST-Standard, controls), time (post-program, 6-month follow-up and 12-month follow-up), gender (females, males) and age (13-17 years; 18-25 years), as well as interaction effects. Baseline scores will be used as a covariate. All analyses will control for accessing external (face-to-face) treatment at any point.

For dichotomous clinical outcomes (e.g., ED diagnosis) logistic regressions will be used. In particular, prevention effects (e.g., new ED cases) and treatment effects (e.g., symptomatic at baseline but not at later points). Potential moderators will be explored to investigate 1) what variables predict level of user engagement and 2) what variables predict greater benefit from standard vs flexible MST delivery. Moderators will include: baseline ED diagnosis; severity of disordered eating; previous treatment; depressive symptoms; gender; and age.

Summary
Brief summary
Media Smart-Targeted (MST) is a 9-module website designed to reduce eating disorder risk (ED: e.g., anorexia nervosa, bulimia nervosa, binge eating disorder) in young-adult women aged 18-25 years. MST was adapted from Media Smart, which is the leading school-based ED risk reduction program worldwide. MST encourages users to look at the way they interpret media messages, their use of social media and strategies that might be helpful in reducing pressures they feel.

This study will expand on the first MST study by increasing the target audience and maximising user engagement by: including both females and males; increasing the target age group to include younger participants (13-17 years in addition to the 18-25 years); refining program content based on results from the first RCT; and, comparing outcomes for flexible program delivery (user’s own pace, MST-F) versus standard weekly module release (MST-S; used in the RCT). Once again we will take a national approach. People will self-refer to the website, complete consent and online baseline questionnaires and then be automatically randomised to: MST-F; MST-S; or control conditions. Measures will then be completed at post-program, 6- and 12-month follow-up. We hypothesise that those in the MST-F condition will complete more of the program than those in the MST-S condition and that this will lead to greater benefits on the outcome variables.
