Stress First Aid is a peer support training designed to provide participants with a tool kit on how to perform a timely safety assessment and response when they suspect a co-worker or peer needs support. SFA trains peers to recognize and communicate about suspected psychological injuries with individuals with the goals of preserving lives, preventing further harm, and promoting recovery. Using the Stress First Aid framework and model, you can learn how to identify stress reactions in yourself and others, reduce the risk for stress injury, and promote coping and resilience among individuals and groups in social, occupational, and academic settings. The overarching aim of Stress First Aid (SFA) is to identify and mitigate the negative impacts of stress before they impair health and well-being. SFA was initially developed under the auspices of the US military for implementation by the United States Navy and Marine Corps. It has since been successfully adapted for use by health care professionals and first responders across the country. The SFA model is based on five evidence-informed factors that help people recover from stress and adversity. These include the need for safety, calm, connection, sense of competence or self-efficacy, and hope.
