This 2003 report describes the initial focus and work of the Domestic Violence & Mental Health Policy Initiative (DVMHPI), a Chicago-based project that was founded in 1999. In 2005, DVMHPI launched the National Center on Domestic Violence, Trauma & Mental Health, with funding from the U.S. Department of Health and Human Services; Administration on Children, Youth and Families; Family Violence Prevention and Services Program. While the Center maintains a national focus, DVMHPI continues to carry on the local aspects of the work by building the capacity of Chicago-area service systems to provide accessible, culturally relevant, and DV- and trauma-informed services.
