Child and Family Traumatic Stress Intervention (CFTSI) is an early intervention and secondary prevention model that aims to reduce traumatic stress reactions and posttraumatic stress disorder (PTSD). It is delivered to children aged 7-18 years, together with their parent or caregiver, after the child has experienced a potentially traumatic event (PTE). Examples of PTEs are events such as sexual and physical abuse, domestic violence, community violence, rape, assault, and motor vehicle accidents. Children are referred by law enforcement, child protective services, pediatric emergency rooms, mental health providers, forensic settings, and schools. The goals of CFTSI are to: improve screening and identification of children impacted by traumatic stress; reduce traumatic stress symptoms; increase communication between the caregiver and the child about the child's traumatic stress reactions; provide skills to help master trauma reactions; assess the child's need for longer-term treatment; reduce concrete external stressors (e.g. housing issues, systems negotiation, safety planning, etc.).
