Knowing the characteristics associated with child exposure to spousal abuse could aid in early identification of at-risk children. The purpose of our study is to determine possible factors associated with child witnessing of intimate partner violence (IPV) in Canada using data from the 1999 General Social Survey, a representative telephone survey of Canadians aged 15 years and older. Respondents reporting IPV in the five years prior to the survey were asked whether a child had witnessed the incident. Multivariate logistic regression was used to determine the association between child witnessing of IPV and victim, assault, and help-seeking characteristics. Households in which child witnessing of IPV was reported were distinguished by the following factors: female respondent, visible minority, over age 30, separated, divorced, or widowed, low income, and the presence of children aged 0-14 years. Other significant variables associated with child witnessing of IPV were related to the frequency, reporting, and disclosure of violent incidents.
