As many as 9 in 10 justice-involved youth are affected by traumatic childhood experiences. According to "Healing Invisible Wounds: Why Investing in Trauma-Informed Care for Children Makes Sense," between 75 and 93 percent of youth currently incarcerated in the justice system have had at least one traumatic experience, including sexual abuse, war, community violence, neglect, and maltreatment. Research points to long-term effects of childhood trauma, including emotional problems and negative impacts on youth brain development. However, few of these youth are identified, and fewer yet receive appropriate treatment or placement. This article summarizes recommendations on investing in trauma-informed care from a new study released by the Washington, DC-based Justice Policy Institute.
