This research was designed as an initial attempt to assess relational aggression in preschool-age children. Our goal was to develop reliable measures of relational aggression for young children and to use these instruments to address several important issues (e.g., the relation between this form of aggression and social-psychological adjustment). Results provide evidence that relationally aggressive behaviors appear in childrens behavioral repertoires at relatively young ages, and that these behaviors can be reliably distinguished from overtly aggressive behaviors in preschool-age children. Further, findings indicate that preschool girls are significantly more relationally aggressive and less overtly aggressive than preschool boys. Finally, results show that relational aggression is significantly related to social-psychological maladjustment (e.g., peer rejection) for both boys and girls.

Recent studies of peer victimization have demonstrated the importance of studying relational as well as physical forms of peer maltreatment for understanding childrens social-psychological adjustment problems. Studies in this area have been limited thus far by a focus on school-age children (9-12-year-olds). Given the significance of early identification of childrens social difficulties for intervention and prevention efforts, this research was designed to assess relational and physical peer victimization among preschool-age children (3-5-year-olds). Results indicated that boys were significantly more physically victimized than girls whereas girls were more relationally victimized. Both relational and physical victims experienced greater adjustment problems than did their peers. Relational victimization contributed unique information about adjustment beyond that provided by physical victimization.

Although many past studies of peer maltreatment have focused on physical victimization, the importance of an empirical focus on relational victimization has only recently been recognized. In relational victimization, the perpetrator attempts to harm the target through the manipulation of relationships, threat of damage to them, or both. We review what is currently known about relational victimization with three issues in mind: (a) developmental changes in the manifestation of relational victimization, (b) gender differences in the likelihood of being victimized, and (c) evidence that relational victimization is harmful.
