From physical abuse victim to aggressor : exploring the relationship

This dissertation represents an attempt to better understand why physically abused children are more likely to develop aggressive tendencies. A sample of adolescents receiving child protection services was administered a battery of self-report measures on maltreatment, health, and well-being; an aggression measure was administered a year later. The specific focus was to determine whether aggressive youth were more likely to (1) have suffered harsher physical abuse, (2) generate violence outcome expectancies that favour recourse to aggression, and (3) report higher levels of abuse-related shame. Respectively, the second and third hypotheses were based on social information processing and shame-rage models of aggression.Only the hypothesis of the fast study on maltreatment characteristics was supported. Victims of frequent and severe abuse were more likely to report aggression. As for the second and third study, the expectation of positive outcomes from violence and feelings of shame-rage (as indicated by high levels of guilt-free shame) were actually inversely related to aggression.Even though these results went in the opposite direction of the hypotheses, they are not altogether in conflict with theoretical models. According to L. Rowell Huesmann's description of social information processing, a hostile worldview was considered a mediating factor in the development of aggression problems. The tendency for aggressive youth to expect negative rather than positive outcomes from violence can be interpreted as support for this view. Abuse-related shame was not related to aggression, but it did demonstrate the predicted association with anger and hostility. The suggestion therefore is that feeling shame as a result of abuse leads to pent-up rather than expressed rage.Given these results, it is suggested that victims of harsh maltreatment be targeted for appropriate prevention and skills promotion programs. Also, future research should investigate whether the formation of problematic relationship schemas and the tendency to suppress abuse-related emotions contribute to the maintenance of aggression problems
