Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Whitu For School app is designed to help rangatahi learn evidence-based strategies for maintaining and improving their well-being.

It includes seven modules that can be trialled over a week or at a user’s own pace: 1. Feel (recognising emotions); 2. Relax (relaxation techniques); 3. Be kind to yourself (self-compassion exercises); 4. Be thankful (gratitude exercises); 5. Connect (increasing social support); 6. Look after you body (information on diet, exercise, sleep); and 7. Goal setting (setting Specific, Measurable, Achievable, Realistic, Time-bound (SMART) goals).

Modules contain cartoon-based explanations and exercises, take 5-15 minutes each and can be completed in a flexible manner according to user preference.

Users are encouraged to explore this broad range of strategies, discover the ones that best work for them and keep using them over time. Although there is no expected frequency of use, badge rewards and daily notifications encourage app completion and practice of preferred strategies.

Data entered by users are stored on their devices in an unencrypted SQLite database and can be safely removed at any time by deleting the app

Efficacy
Statistical methods / analysis
Baseline characteristics will be summarised using means and standard deviations or numbers and percentages. Repeated measures ANOVA will be used with linear mixed models to include participants with data at only one or two of the three time points. The main analysis aims 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. Cohens f2 will be calculated as a measure of effect size for the group by time interaction.53 Primary comparisons of interest are between-group differences at 4 weeks and 3 months, with results presented as marginal mean differences, 95% CIs and p-values. Results will be analysed on an intention-to-treat basis. Quantitative data will be analysed using Strata® software version 17, with statistical significance set at p<0.05. Qualitative feedback during phase 2 and 3 will be independently extracted and analysed by two authors (HT and AS) using a general inductive approach.54 Any coding discrepancies will be resolved by consensus.
