Description of intervention(s) / exposure
The internet cognitive behavioural therapy (i-CBT) program will comprise 8 modules (these take approximately 15 mins each) over a 6-week period that will be delivered via the This Way Up clinic website www.thiswayup.org.au. Participants will be encouraged to complete a little over one module a week, and reminded to complete modules through automated emails if they do not complete them on time. These modules are presented through comic-style illustrations that intersperse lessons in key cognitive behavioural therapy (CBT) principles alongside the narrative of a student dealing with stress. In particular these modules will cover psychoeducation on stress and well-being, skills in thought challenging, behavioural activation, goal setting, problem solving, study skills, and mindfulness. Each module ends with a lesson summary that participants can only download upon completing the module. This summary provides a brief overview of the module and includes a homework task for the student to complete before beginning the next module. For example for module 1, participants are required to complete a stress level checklist. For the relaxation module, participants are encouraged to complete relaxation activities each day, or for the managing thinking module, they are encouraged to complete a thought challenging worksheet.

Efficacy
Statistical methods / analysis
Sample size was determined with a power analysis, using a power of 0.8, and expected effect size of 0.4 within groups, and an effect size of 0.8 between groups. Expected effect sizes was estimated from existing literature on virtual reality interventions for public speaking anxiety.

Linear mixed models will be used to analyse the repeated measures data, with fixed factors of treatment group (iCBT/wait list), time, and the time by group interactions entered into the model. We will also conduct adjusted (with appropriate covariates) and unadjusted models to evaluate the outcomes for each of the outcome measures.

Summary
Brief summary
The purpose of the study is to assess the efficacy of the i-CBT stress and well-being program for university students. We expect that the participants in the treatment group will show lower levels of psychological distress and higher levels of well-being at post-treatment and one-month follow up than participants in the waitlist control group.
