Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention, HeadGear, is a smartphone application-based intervention centred on behavioural activation and mindfulness therapy. The main therapeutic component of the HeadGear app takes the form of a 30-day challenge in which users’ complete one ‘mission’ daily (approximately 10 minutes). These ‘missions’ include psychoeducational videos on coping skills/resiliency, mindfulness, and behavioural activation; mindfulness exercises; value-driven activity planning, goal-setting, and review; and coping skill development (problem solving, sleep, grounding, alcohol use, assertiveness, and training in adaptive forms of coping). The first daily challenge will involve the completion of a risk calculator, which will assess and provide participants with personalised feedback regarding their risk for future mental health issues. The risk calculator consists of 20 items developed from the HILDA derived risk algorithm. The risk factor items are based on participant self-report. The HILDA risk items include: age, gender, Aboriginal and Torres Strait Islander status, active carer, freedom to decide work, satisfaction with hours worked, satisfaction with employment opportunities, three or more times physical activity, alcohol use, episodes of distress in the previous two years, satisfaction with health, satisfaction with the neighbourhood, satisfaction with partner, satisfaction with the way tasks are divided with partner, have someone to confide in, feeling being pushed around, and English as a second language. The HILDA questions and response items were replicated from the original items included in the HILDA survey, apart from age, which is measured here as a continuous measure. Users will receive personalised risk feedback immediately after completing the risk calculator. The personalised risk feedback involves an interactive icon array which displays the calculated numerical risk estimate of developing anxiety and depression within the next year, along with a text description.
Other components of the app include a mood monitoring widget, a toolbox of skills (which is built from the challenge as it is completed), and support service helplines. users will have access to the application indefinitely. The application monitors use time and frequency, and mission completion rates

Statistical methods / analysis
Data will be analysed via descriptive statistics derived from participants’ smartphone use data to characterise feasibility and acceptability in the pilot study. Pearson product-moment correlation coefficients were used to examine the association between baseline continuous variables (e.g. K6) and application use (ie, days used, number of times used per day). Spearman’s rank correlation coefficients were used to examine the association categorical variables (e.g. gender) and application use. Paired samples t tests were used to test for differences between pretrial and post-trial clinical outcomes (K6).

Pilot studies tend to be underpowered in order to determine “proof of concept.” In order to ensure adequate development time and resources for developing the web-based program in the current study, the recruitment time window and sample size is purposefully limited. To adjust for these factors, and given the goals for examining initial feasibility of the program, significance was determined at a value of p = .05. This provided adequate power of .80 to detect a medium effect size of Cohen’s d = .60 with a sample size of 40 participants per group using a two tailed test and alpha of p = .05 (Levin, 2014).
