The purpose of this study was to examine the three most common types of caregivers in the child welfare system (birth parents, relative caregivers, and foster parents), an active child welfare case, caregivers' endorsement of barriers to mental health services and mental health service use by caregivers for the children under their care. The sample consisted of 430 dyads (caregivers and their children). Results indicate that an active child welfare case, provider characteristics, and accessibility of services predicted mental health service use for children. Implications for the child welfare and mental health systems are discussed. (Contains 3 tables.)
