This study reviewed merged records of children (N=40,211, 3,262 disabled) in Omaha, Nebraska, during 1994-95. An electronic merger of school records with child abuse, foster care, and police records was followed by a review of maltreatment incidents. Findings indicated a 9 percent prevalence rate of maltreatment for nondisabled children and a 31 percent prevalence rate for disabled children. (Contains references.) (DB)
