Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Whitu app includes seven modules that can be completed within a week to learn evidence-based coping skills based on CBT, psychoeducation and positive psychology techniques. The seven modules are: (1) identifying and rating emotions, (2) relaxation, (3) self-compassion, (4) gratitude, (5) staying connected, (6) physical care, and (7) goal setting. The app uses short videos and interactive activities to allow participants to practice the coping strategies that are taught in each module (e.g. a relaxation technique). Participants are asked to complete one module per day and to complete the modules in one week. Each module takes approximately 10 to 15 minutes to complete. Participants will be asked to complete module 1 first, but the other modules can be completed in any order. Adherence to the modules will be assessed using self-report.

The control group will be sent a link via email to the University of Auckland’s existing ‘Be Well’ website. The control group will be given no specific instruction - participants access to the website is wholly at their own discretion.
After the completion of the 3-month follow-up, we will offer the control group access to the Whitu wellbeing app as a thank you for participating in the study. The active control group will not be followed up past the 3-month time point.

Why?, (4) What did you like about the app?, (5) How can we make the app better for young people in the future? and (7) Did you experience any technical difficulties with the app? If yes, what happened?

Efficacy
Statistical methods / analysis
Data will be analysed in SPSS or SAS. Prior to any data analysis, data will be tested for violations of statistical assumptions and screened for errors and outliers. If parametric assumptions are not met due to non-normality, transformations or alternatively non-parametric tests will be used. Linear mixed models will be used to determine whether changes in psychological outcomes are the result of the interaction between the intervention group and time, with post-hoc tests to assess pairwise comparisons of groups at each time point and within-group changes over time. Means, standard deviations and confidence intervals will be presented with the analysis. Data will be analysed based on both intention-to-treat and per protocol.
