Correlates of joint child protection and police child sexual abuse investigations: results from the Canadian Incidence Study of Reported Child Abuse and Neglect–2008

INTRODUCTION: Our study examines the frequency of joint investigations by child protection workers and the police in sexual abuse investigations compared to other maltreatment types and the association of child-, caregiver-, maltreatment- and investigation-related characteristics in joint investigations, focussing specifically on investigations involving sexual abuse. METHODS: We analyzed data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008 using logistic regression. RESULTS: The data suggest that sexual abuse (55%), and then physical abuse, neglect and emotional maltreatment, are most often co-investigated. Substantiation of maltreatment, severity of maltreatment, placement in out-of-home care, child welfare court involvement and referral of a family member to specialized services was more likely when the police were involved in an investigation. CONCLUSION: This study adds to the limited information on correlates of joint child protection agency and police investigations. Further research is needed to determine the effectiveness of these joint investigations.
