PeerOnCall: Implementing and Evaluating App-Based Peer Support in Canadian Fire Services

The structured implementation (intervention) group will follow a structured protocol designed to promote weekly app engagement. This includes regular updates to customized content, reminders to use the app, and feedback on use. Weekly content updates and push notifications will be provided through the app, and the research team will communicate monthly with organizational champions with feedback reports on app utilization to reinforce engagement.

The standard implementation (control) group will receive baseline support, allowing firefighters to use the app as they choose. The research team will provide an initial orientation for organizations and peer supporters, but the organizational champion will be responsible for communication and follow-up. The research team will respond to questions and prompt data collection.
