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.

Summary
Brief summary
The rangatahi (young people) of Aotearoa (New Zealand) are experiencing significant and increasing challenges to their well-being, with 23% of high school students reporting significant depressive symptoms; 6% percent attempting suicide; and 19% having difficulties accessing mental health support each year. In recent years, rapidly evolving smart technology has led to the development of a range of digital mental health interventions including information-oriented websites for learning about stress management, game-based online therapies for common mental health problems and self-help applications with which to improve well-being. During the early phase of the COVID-19 pandemic, our team was concerned about international trends in psychological issues impacting rangatahi in Aotearoa as social distancing and lockdowns commenced and developed an evidence-based well-being app called 'Whitu - seven ways in seven days'. The app includes cognitive behaviour therapy, mindfulness and gratitude paradigms. During an open trial and randomised controlled trial, this app was shown to improve wellbeing, self-compassion, sleep, stress levels and depression in users. We are now planning on adapting the app for high school students and wish to test the efficacy and acceptability of app with 13-15 year olds via a further randomised controlled trial. We will recruit 90 participants from two NZ high schools and randomise them to an intervention group or waitlist group. We will collect wellbeing-related outcome measures at baseline, 1 month and 3 months.
