This manual was developed by the Ohio Domestic Violence Network with funding from the Ohio Department of Mental Health and SAMHSA. It includes information on understanding trauma, responding to trauma survivors, trauma-informed care best practices, trauma-informed protocols (for hotline calls, intakes, support groups, exit interviews, safety planning and parenting), and vicarious trauma. It also includes a practice checklist developed by the Center on Domestic Violence, Trauma & Mental Health and a comparison between the empowerment model and a trauma-informed approach.
