The Adverse Childhood Experiences Study and other research shows that as many as one-fourth of U.S. children experience maltreatment before age 18. What happens to these children and their families? We will explore how maltreatment intersects with child and parent mental health and well-being, and how characteristics such as race and income affect whether maltreatment is identified and the assistance families receive. For those families who become involved in the child welfare system, we will examine how mental health needs are addressed. Finally, we will explore how child maltreatment affects those professionals and institutions charged with helping maltreated children.
