CISD, or Critical Incident Stress Debriefing, is a mental health intervention model that was created to help individuals who have experienced a traumatic event. The goal of CISD is to provide a supportive and safe environment for individuals to express their thoughts and feelings about the traumatic event, and to help them process and cope with their emotions. Some other terms that are commonly used to describe CISD include critical incident stress management (CISM), psychological first aid (PFA), and trauma-focused therapy. Whatever the term used, the important thing is to ensure that those who have experienced a traumatic event have access to the support and care they need to heal and move forward.
