Psychological first aid (PFA) is a method of helping people in distress so they feel calm and supported to cope better with their challenges. It is a way of assisting someone to manage their situation and make informed decisions. The basis of psychological first aid is caring about the person in distress and showing empathy. It involves paying attention to reactions, active listening and, if needed, practical assistance, such as problem solving, help to access basic needs or referring to further options for assistance. PFA helps normalize worry and other emotions, PFA also promotes healthy coping and provides feelings of safety, calming, and hope. These guidelines can be used by Red Cross Red Crescent National Societies to set up and run different kind of remote services for the public during the time of a COVID-19 response. It should be noted that the target group for the guidelines are adults.
