The Administration for Children and Families, the Substance Abuse and Mental Health Services Administrations, the Administration for Community Living, the Offices of the Assistant Secretary for Health and the Assistant Secretary for Planning and Evaluation at HHS have worked together to develop this Guide to Trauma-Informed Human Services. The guide is intended to provide an introduction to the topic of trauma, a discussion of why understanding and addressing trauma is important for human services programs, and a “road map” to find relevant resources.
