Purpose: The Child Abuse Prevention and Treatment Act requires child welfare agencies to have provisions in place to refer young children to early intervention services, yet the socioemotional health needs of children are often challenging to recognize and treat effectively. This study reviews the substantive and psychometric properties of screening instruments designed for children ages 10 and younger. Methods: Major social science databases, websites of national organizations, and the "Mental Measurements Yearbook" were used to identify instruments for review. Results: Twenty-four instruments met review criteria, and eight show above-average measurement properties and testing, tap children's strengths and concerns, and have evidence of validity with families similar to child welfare-involved families. Discussion: It is important to effectively screen for children showing concerns in early childhood, so that treatment and prevention can be prioritized. This study indicated several tools with adequate testing and with emerging evidence and applicability to child welfare.
