Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention condition takes the form of a smartphone application (app) called Headgear. Headgear is designed for self-directed use by an individual on a smartphone device. The application features interactive content, delivered on-screen and by audio using text, static and interactive image displays and videos. The app software is compatible with both Apple and Android operating systems and available for download online via the user’s respective app store (iTunes or Google Play) or the Trial website. The application can be accessed by the participant on their smartphone /mobile phone at a time and location of their choosing. The app monitors usage data including time (amount of time spent in-app) and frequency of use, number of log-ins and 'challenge' completion rates. This data will be used to examine program engagement. Participants will have access to the application indefinitely. The intervention application is designed around a 30-day timeframe. However, the active phase of this trial during which the experimental condition will be delivered and monitored is 30 days from baseline, with follow-up assessments at 5-weeks post-baseline, 3 months and 12 months.

The intervention, HeadGear, is a smartphone application (‘app’)-based intervention centered 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 ’challenge’ daily (approximately 5-10 minutes per day, for 30 days). These ‘challenges’ 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 Household, Income and Labour Dynamics in Australia Survey (HILDA) derived risk algorithm.

Attention-matched control condition:
The attention-matched control condition, ‘HeadGear lite’, is a simplified version of the same application used in the intervention condition, and is designed to control for time spent interacting with an application. This ‘lite’ application features daily mood monitoring for 30 days, instead of the 30-day ‘challenge’ component, it does also include the 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 Household, Income and Labour Dynamics in Australia Survey (HILDA) derived risk algorithm.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed as randomisation of participants into intervention or attention-matched control condition will occur immediately following completion of the baseline assessment using automated procedures integrated into the trial management software.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The algorithm for randomisation will consist of a stratified block design.
Masking / blinding

Efficacy
Statistical methods / analysis
The primary outcome will look for a difference in depression symptomatology (using the PHQ-9 score) between the intervention and control group. Linear mixed models will be employed to analyse the effect of intervention on the PHQ-9 scale, adjusted for potential confounders risk score (high/med/low), baseline score, and allowing a random effect for employer. After review of Headgear pilot data, the effect size was estimated to be 0.35. This effect size was entered into the statistical program R (R Core Team (2013). Power was set at 80% and conservative 2-tailed tests were assumed even though a directional hypothesis is proposed. Based on this testing a sample size of 266 per group was needed (total N = 532). A conservative dropout rate of 40% at follow-up was estimated, which increased the sample required to be 851 participants.
Analysis plan:
Data coding and analysis will be carried out by the authors using available software packages including STATA version 12.0 and the Statistical Package for the Social Sciences (SPSS) version 20.0. Data on screening, refusals, and dropout are coded and reported as per CONSORT. Primary analyses will be undertaken on an intention-to-treat (ITT) basis, including data for all participants who were randomised and completed risk assessment, irrespective of their level of adherence to the intervention or whether they withdrew at any point in time. Categorical and continuous measures of outcome will be examined using mixed or marginal longitudinal models (i.e., mixed model repeated measures, generalised estimating equation modelling) as appropriate. A ‘completers’ analysis on all participants completing at least 75% of the intervention will be undertaken as a secondary analysis. Transformations, including dichotomisation or other categorisation, will be undertaken as necessary to meet distributional assumptions and to accommodate outlying observations. The potential effects of a number of covariates and confounders will be modelled in the major analyses.
