Positive behavioral health outcomes are affected by a variety of factors including social, biological, economic and physical environments. These social determinants of mental health (SDOMH) affect not only individual children but the communities and neighborhoods in which children are expected to live, play and thrive. The State must ensure appropriate supports are available from pre-natal to age 21, so that children can grow in environments that have minimized the root causes of common illnesses like anxiety and depression, while equipping children with the ability to recognize and regulate their emotions and maintain healthy relationships. The following agenda provides a roadmap for state leaders on the components needed to establish a successful children's behavioral health system including community investments, individual service supports, community education, and data-sharing. The examples provided are not exhaustive but are key recommendations for a delivery system that develops and supports a well-trained workforce, educates communities, identifies kids in need, and provides appropriate treatment and support.
