Psychological First Aid (PFA) is an evidence-informed intervention model to assist students, staff, and families in the immediate aftermath of a disaster or emergency event, and can be used by any trained staff member or school administrator. PFA is designed to reduce the initial distress and trauma caused by emergencies, and to help students return to their usual school-based activities after such an event. By using these brief and effective interventions in the form of the five steps of PFA (Listen, Protect, Connect, Model, and Teach), schools can provide a long-lasting, positive influence on trauma-related stress.
