Children's victimization experiences within relationships characterized by mutual animosity were examined among 210 6th- and 7th-grade boys and girls. Participants reported that a greater proportion of mutual antipathies, relative to other peers, victimized them. Moreover, the receipt of victimization within antipathetic relationships was greater when the partner in the relationship was aggressive, physically strong, non-victimized and had low levels of internalizing problems. Perceptions of victimization and levels of maladjustment were also found to be more strongly associated with victimization from mutual antipathies than with victimization from other peers. Together, these findings highlight the importance of studying victimization in the context of antipathetic relationships and contribute to an emerging literature on the developmental significance of these relationships.
