In this research brief, data from the National Survey of Child and Adolescent Well-Being (NSCAW) is used to describe SHCNs of children in the CWS. NSCAW is a national longitudinal study of the well-being of more than 5,500 children ages 14 and younger who were involved in child maltreatment investigations by CWS in 1999 and 2000. Data from NSCAW cannot be directly translated to fit the Maternal and Child Health Bureau’s definition of child SHCNs. For instance, NSCAW does not provide information about problem severity or estimates of the extent of services needed or utilized over time for given problems. NSCAW does, however, allow the examination of specific chronic health conditions and special needs by problem type and according to caregiver report.
