In 2003, Congress amended the Child Abuse Protection and Treatment Act (CAPTA) to require that all child victims of substantiated abuse or neglect under the age of 3 years be assessed for developmental concerns. To date, there has been little study of CAPTA's implementation in Part C early intervention programs. The "Professional Interventionist CAPTA Survey" (PICS) was developed to assess perceptions of Part C providers related to serving children and families referred from child welfare. The PICS provides a measure of providers' perceptions of the CAPTA mandate. Initial results of the PICS suggest that it holds promise for future implementation research and program assessment for Part C early childhood intervention related to CAPTA.
