"OnCall": Implementing a Mobile Health Approach to Post-traumatic Stress Injury (PTSI) Prevention and Peer Support for Canadian Public Safety Personnel

Public Safety Personnel (PSP), including, but not limited to correctional workers, emergency communications, firefighters, paramedics, and police officers have an elevated risk of post-traumatic stress injury (PTSI) due to the challenging nature of their work. Unfortunately, they also face barriers to seeking support due to stigma combined with gendered beliefs regarding perception of weakness, pressure to control emotions and reluctance to seek help, as well as lack of access to timely, high-quality care, particularly for those who work in rural or remote areas. Peer support is highly valued, however peer support services are often fragmented with inconsistencies in training and varied models of service delivery, and there are almost no systematic evaluations to inform continuous improvements. Mobile health technology (m-health apps) can be an effective and efficient approach to reaching large numbers of PSP, regardless of location, and an accessible conduit to peer (and professional) support. This research study will explore the implementation and impact of a new m-health platform (OnCall and OnCallSupport) that is customized for public safety personnel.

There are two sets of research questions guiding this project. The first set relates to implementation; How do frontline PSP utilize the OnCall support app? How do these patterns of use change over time? What organizational and social forces shape patterns of app use? The Consolidated Framework for Implementation Research (CFIR) will be used to guide data collection and analysis of the app implementation. The second set of questions relate to impact of the app on service users. Does use of the app increase outreach to peer support? Does peer support provided in the app reduce levels of mental distress? Does use of the app affect mental health literacy, symptoms of anxiety, depression and post-traumatic stress disorder (PTSD), and/or work performance?

Implementation of the app will be studied over a 6 month period with employees in 6-8 PSP organizations. Organizations will be purposively selected to explore differences in size, geographical location, and type of service. All participating organizations must have an established peer support program, with established training and ongoing support for the peer providers. The organizations must also identify 1-2 organizational champions who will liaise with the research team, organizational leaders and frontline employees. Peer providers within the organization will be oriented to the OnCallSupport app, and asked to provide support via this m-health platform. All employees in each organization will then be invited to download the OnCall app via tokens provided by the research team. No personal data is collected in the app, and connections with the peer providers are completely private. Employees will also be invited to complete baseline, 3 month and 6 month follow-up surveys to track changes in help-outreach, mental health literacy, symptoms of anxiety, depression and PTSD, as well as work performance. Employees are able to use the app without participating in the online surveys.

Data collection will include: a) interviews with champions in each organization at the start and end of the 6-month trial, b) surveys with app users at baseline, 3-month and 6-months, c) review of anonymous, aggregate app utilization data, over the trial period and d) focus group discussions with peer support providers at 1 month and 6 months.

Analysis of the implementation data (interview transcripts with organizational champions, focus group transcripts with peer support providers, and software analytics re: patterns of app use) will be informed by the CFIR framework to identify how the outer setting, inner setting, the intervention, participants and process of implementation affect how employees respond to the app.
