Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will complete 4 lessons of an internet-delivered cognitive behaviour therapy (iCBT) program, the UniWellbeing Course, focusing on the management of stress, anxiety, low mood and depression. All 4 Lessons will be administered via the internet and one lesson will be completed every 7 to 10 days. Each lesson will take about 15 minutes to complete. Participants will also have access to summaries of each lesson, and will read anonymous case stories about others with anxiety and depression, taking a further 15 minutes per summary. All participants will also receive automatic emails. These emails will be brief and sent each week to: (1) alert participants about new lessons available; (2) congratulate them for completing lessons; and (3) reminding them about lessons they have not completed. Weekly phone calls from a therapist from the university student counselling service will also be provided throughout the course. The duration of the phone calls is expected to be 5-10 minutes per week. The duration of the program is 5 weeks. Study questionnaires will be administered at pre-treatment, post-treatment and then 3-months post-treatment. These questionnaires will take about 5 to 10 minutes to complete at each time point. Participants lesson completion, time spent on lessons and number of logins will be recorded by the clinical software system through which participants access the course.

Efficacy
Statistical methods / analysis
All analyses will be carried out using conservative intention-to-treat principles and using generalised estimating equation (GEE) modelling. GEE modelling is a robust statistical approach for analysing clinical trial data and these analyses will employ an appropriate covariance structure and maximum likelihood estimation, which provides unbiased estimates in the case of missing data; under the assumption that data is missing at random.

With alpha set at 0.05, power set at 0.80 and a sample size of 120, the study is powered to enable the detection of small-to-large effect size (i.e., Cohen’s d > 0.30) changes in symptoms at each time point. However, 200 participants will be recruited to account for attrition and enable exploratory analyses to examine the prediction and moderation of clinical response in subgroups of participants (e.g., participants with severe versus milder symptoms).

Predictors of treatment response will be explored. Clinical outcomes will be modelled on the basis of: (1) treatment adherence and engagement; and (2) participants initial symptom levels prior to participation.

Participant recruitment will be ongoing until the revised end of the trial period (December 2022). While the minimum desired sample size has been achieved, we we have ethical approval to recruit participants for more extensive exploratory analyses. Notably, our existing research data suggests the intervention is efficacious and is currently providing free treatment that is otherwise unavailable for a treatment-seeking population.
