This report presents results of a 50-state policy survey conducted by the National Center for Children in Poverty, Georgetown University McCourt School of Public Policy Center for Children and Families, and Johnson Policy Consulting. The survey asked state Medicaid agency leaders about Medicaid policies related to screenings and services designed to identify, prevent, and treat infant-early childhood mental health problems. The results and recommendations presented in this report can help mental health and early childhood leaders take stock of current Medicaid policies and their potential to support infant-early childhood mental health.
