"This brief addresses the need for a comprehensive approach to trauma intervention across service settings. In doing so, we define these complementary approaches, identify core principles and current practice for each, and discuss how both are being integrated across service sectors. Finally, we identify next steps for providers, researchers, and policymakers to ensure that all service systems are prepared to sustain this comprehensive approach to trauma intervention" (p. 1) "“Trauma-specific services” and “trauma-informed care” are sometimes used interchangeably; both provide care for people exposed to traumatic stress. However, trauma-specific services are clinical interventions, whereas trauma-informed care addresses organizational culture and practice. Trauma-specific services are clinical interventions that are designed to address trauma-related symptoms and PTSD directly in individuals and groups. In contrast, trauma-informed care is defined as a universal framework that requires changes to the practices, policies, and culture of an entire organization, so all staff have the awareness, knowledge, and skills needed to support trauma survivors" (p. 4). Sections of this publication include: introduction; prevalence and impact of traumatic stress; trauma-specific vs. trauma-informed; trauma-informed care and trauma-specific services—why both are needed; trauma intervention across service systems; next steps for the field; and conclusion.
