Children's peer relationships are important to their socioemotional and cognitive development; thus, understanding the determinants of such relationships is of ongoing interest. It was hypothesized that gender behaviors and affiliations would predict peer acceptance and victimization. Path analyses using data from 192 fourth graders showed that for both genders, engaging in feminine activities predicted less peer‐reported acceptance and greater victimization, and engaging in masculine activities predicted greater peer acceptance. Affiliating with male peers was associated with greater peer‐reported acceptance for both genders, and greater self‐reported peer acceptance for boys. Indirect effects showed that the link between gender behaviors and victimization is mediated by peer acceptance. These findings support the contention that gender behaviors relate to the quality of children's relationships.
