Description of intervention(s) / exposure
This pilot study aims to explore the use and preferences of emergency service workers regarding potential uptake of a smartphone-based Mental Health (MH) intervention providing evidence-based prevention strategies for mental distress for Emergency Service Workers in Australia. The preliminary effectiveness for whether the smartphone-based MH intervention leads to any improvement in outcomes such as distress, wellbeing and common mental disorders will furthermore be explored. The smartphone application is intended to be used in a larger scale study aimed at promoting mental health and wellbeing within Emergency Service Workers (ESWs) and their families.

A 3-month single-arm study design will be used in this pilot study to examine the feasibility and acceptability of this smartphone-based MH interventions among a sample of 63 Emergency Service Workers (ESWs) (18 years and older) in Australia. Baseline assessment will occur immediately after participants consent to participate in the study. Participants will then download the app and use it daily for approximately 21 days. Participant will be encouraged to use the app daily for a minimum of 15 minutes each day. Post-intervention assessment will occur 4 weeks (1 month) after baseline.

This pilot study will involve two key phases: Phase 1 will focus on exploring the feasibility and acceptability of this novel, purpose-built smartphone app, which will include the administration of usability and user experience surveys and qualitative interviews. The secondary objectives of Phase 2 are to describe app usage patterns (i.e. number of logins, time spent using the app) to help identify patterns in how participants engage with the smartphone application, and provide preliminary evidence for participant reported clinical outcomes (such as alcohol and other drug use, self-reported recovery, and mental health), collected via user experience surveys, qualitative interviews and in -app. Usage Information which will be passively collected whilst users engage with the application (i.e. does not require any direct data collection).

The Build Back Better app has been developed by researchers from Workplace Mental Health Team, Black Dog Institute, UNSW, and has been adapted from HeadGear, a smartphone application based on recognised and evidence-based psychological approaches including psychoeducation, behavioural activation, value-driven activity planning, goal-setting, and coping skill development and mindfulness. The Build Back Better app content and visual presentation has been modified to be suitable for Emergency Service Workers (ESWs) and their families, i.e. targeting depression, anxiety and Post Traumatic Stress Disorder (PTSD) complaints. The Build Back Better is designed for day -to- day use, and similar to HeadGear, the app content in Build Back Better is presented in the form of videos (and voiceovers), audio-recordings, and activities, providing the user with proven effective psychological approaches including problem solving, behavioural activation, mindfulness and grounding tasks, all designed to upskill users and promote wellbeing. In -app activities are including guided mindfulness exercises; value-driven activity planning, goal-setting and review; coping skill development (i.e. interactive role playing task regarding: problem solving, improving sleep, grounding methods, alcohol use, assertiveness, and training in thought managing/challenging) and also a mood monitoring widget. Different from Headgear, the app Build Back Better furthermore tailors functionalities and content based on user preferences; i.e. what complaints users are currently experiencing and what they would like to work on in this app.

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 will be used to examine the association between baseline continuous variables and application use (i.e., days used, number of times used per day). Spearman’s rank correlation coefficients will be used to examine the association between categorical variables (i.e. gender) and application use. Changes in participants’ wellbeing and mental health levels from baseline to post-test will be examined using paired sample t-tests (i.e. primary and secondary outcomes).

Qualitative data collected through semi-structured focus group will be analysed using an inductive thematic analysis approach. This approach is data-driven, and involves becoming familiar with the data, generating initial codes, searching for themes among codes and refining themes to better fit the data.

Based on review of the available literature of earlier comparable (pilot) studies using eHealth interventions, a sample size of N = 63 is required to detect a small within group effect difference (d = 0.3) with a 80% power with a 0.05 significance level. With expectation of 30% of participants to be found to be unsuitable or lost to follow-up, drop-outs, and noncompliance, at least 63 participants will need to be enrolled.

Summary
Brief summary
Our research team has been funded by the Australian Government Department of Home Affairs to provide a suite of integrated mental health resources for individuals affected by the 2019/2020 bushfires (emergency service workers and their families), including an app-based prevention intervention tailored to the needs of this population.

This pilot study aims to examine the feasibility of a smartphone application: Build Back Better; in providing evidence-based prevention strategies for anxiety, depression and PTSD for Emergency Service Workers and their adult family. The preliminary effectiveness for whether the intervention leads to any improvement in outcomes such as distress, wellbeing and common mental disorders will furthermore be explored. Participants will complete assessments at baseline and 1 month post- baseline.

The smartphone application is intended to be used in a larger scale study aimed at promoting mental health and wellbeing within Emergency Service Workers and their families.

The research questions/hypothesis that this study seeks to address are:
1. Explore the engagement with the components the app?
2. Explore the level of satisfaction with the app?
3. Explore the preferences of these individuals in terms of app content, format and design?
4. Explore the preliminary effectiveness in terms of improvements in wellbeing and symptom reduction? These include changes in alcohol and other drug use; self-reported recovery; health-related quality of life and mental health symptoms.
