2nd edition. The Pan American Health Organization and the Caribbean Development Bank developed this booklet as a tool to help you take care of yourself and your community during crisis situations. This is achieved through psychological first aid, also known as PFA, a humane, supportive and practical response to a fellow human being who is suffering and may need support. In this booklet, our “PFA helper” will guide you through the three basic principles of PFA: look, listen and link. This will help you to approach affected people, listen and understand their needs, and link them with practical support and information. It will also bring to your attention the needs of specific groups, including men, women, children and adolescents, and people with disabilities, among others. Enjoy the booklet. Read it again from time to time, share it with friends, family and members of your community, and spread the message: “Stronger together”
