Aggression in Children Exposed to Intimate Partner Violence: A Comparison of Maternal, Sibling, and Observer Perspectives.

The negative effects of exposure to intimate partner violence (IPV) on children have been well documented, including externalizing difficulties such as aggression. Although aggressive behavior is a common concern for these children, sibling aggression in children exposed to IPV has rarely been studied. Our purpose was to investigate similarities and differences in multiple informant reports of aggression by siblings exposed to IPV, and to examine how exposure to IPV was linked to these differing perspectives. Forty-seven sibling dyads and their mothers were recruited from the community. Aggression was assessed by observers, by mothers, and by the siblings themselves, whereas IPV was assessed by both maternal and child report. Informants had very differing views on aggression. Regression results indicated that children's reports of their own exposure to IPV accounted for significant variance in observed aggression between siblings, as well as in the maternal reports of aggression by both siblings. Aggression did not vary by sibling age, sex, or age spacing. Results were discussed within a risk and resilience framework.
