Many children experience multiple incidents of abuse, involving either the same perpetrator or different perpetrators. However, neither the literature on child abuse nor the literature on repeat victimization has considered why some abused or neglected children are more vulnerable to further abuse than others. Victimology has highlighted the interaction between the victim and the offender. It places the full responsibility for the incident on the perpetrator. However, it also recognizes that offenders naturally select the child most vulnerable to their advances, the child who is unlikely to expose the event, and the child who is perhaps lonely and neglected enough to regard the abuse as attention and affection. Examining victim differences that shape the risks of repeat victimization is one aspect of efforts to reduce a child's vulnerability to subsequent victimization.
