To be trauma-informed is to understand the involvement and impact of violence and victimization in the lives of most consumers of mental health, substance abuse, and other services. It is also to apply that
understanding in providing services and designing service systems to accommodate the requirements and vulnerabilities of trauma survivors and to facilitate their participation in treatment. This lesson will explain the difference between trauma-informed care and trauma-specific interventions, briefly review trauma history prevalences among consumers of mental health services, describe the development of a trauma-informed perspective in mental health, and discuss how standard clinical practices may inadvertently retraumatize those with trauma histories. This lesson will also outline the central features of a trauma-informed organization/department and the 5 principles of trauma-informed practice. Given the prevalence of traumatic experiences, especially those during development, and their long-standing effects on patients’ lives, the trauma-informed perspective offers a compelling and humane organizing principle for conceptualizing and addressing many of the problems and challenges facing those seeking mental health and other services.
