This study aims to compare, among a representative sample of substantiated child maltreatment cases, the characteristics of those with intellectual disability (ID) from those without ID. Using the 2008 Canadian Incidence Study of Reported Child Abuse and Neglect, 5,797 cases of substantiated maltreatment that involved children aged between 0 and 14 years were analyzed. One in 10 children (11.3%) was identified with ID. Results revealed functional problems to be higher among children with ID and their parents. Moreover, children with ID experienced more severe maltreatment, and were more often referred to ongoing child protection services. These findings suggest that maltreated children with ID are facing additional challenges that must be accounted for in service planning and delivery.
