Determinants of maltreatment substantiation in a sample of infants involved with the child welfare system

Children under one year of age are highly vulnerable to child maltreatment, which can lead to serious immediate and long-term physical and mental health consequences. Child welfare workers encounter unique challenges when assessing allegations of maltreatment involving infants. This study identifies correlates of maltreatment substantiation in a sample of 793 infants less than one year of age investigated by child welfare. It is based on data from the 2003 Canadian Incidence Study of Reported Child Abuse and Neglect (CIS-2003), a national study of reports of child maltreatment. The analysis consisted of two stages. First, bivariate analyses were conducted using unadjusted odds ratios and chi-square tests on variables known to be associated with substantiation. In the second stage, a logistic regression was performed to examine these associations in a multivariate model.Multivariate findings suggest that certain vulnerabilities present in the primary caregiver, such as substance abuse and few social supports, as well as the child's positive toxicology at birth are associated with substantiated infant maltreatment. Exposure to domestic violence, which is reported mostly by the police, and physical harm stemming from maltreatment are strongly associated with substantiation, whereas reports of physical abuse and neglect have an inverse relationship. The authors discuss these results and implications for policy and programs.

► We analyze maltreatment substantiation in infant investigations by child welfare.
► Caregiver’s vulnerabilities are highly associated with maltreatment substantiation.
► Multiple caregiver vulnerabilites increase the likelihood of substantiation.
► Exposure to domestic violence (reported mostly by police) is substantiated most often.
► Maltreatment-related physical harm is positively associated with substantiation.
