CWRP Information Sheet #93E. Toronto, ON: Faculty of Social Work, University of Toronto.
The Ontario Incidence Study of Reported Child Abuse and Neglect (OIS), 2008 is the fourth provincial study to examine the incidence of reported child maltreatment and the characteristics of children and families investigated by child welfare authorities in Ontario. The first OIS was conducted in 1993, with subsequent studies in 1998, 2003, and most recently 2008. The OIS collects information about child maltreatment-related investigations directly from investigating child protection workers. This fact sheet compares maltreatment investigations documented in the 1993, 1998, 2003, and 2008 cycles of the OIS, specifically examining the primary form of maltreatment identified in substantiated investigations.
