Psychological first aid (PFA) provides basic emotional and practical support to individuals in the immediate aftermath of critical incidents or disasters. It aims to stabilize individuals, reduce distress, and help them cope with and recover from the event. PFA is delivered by social workers, health workers, and disaster response teams on-site at shelters, hospitals, and other locations. It involves assessing needs, providing information, connecting individuals to social supports, and referring those with severe distress to professional mental health services. The goals of PFA are to relieve suffering, improve short-term functioning, and accelerate recovery.
