This study examines the association between maternal disciplinary strategies and children's level of relational aggression, and then compares these associations with those found with overt aggression. Eighty‐two 4th graders (aged 9–11 years) completed peer nomination measures of relational and overt aggression, and their mothers completed a questionnaire designed to assess their use of disciplinary strategies (e.g. authoritarian, authoritative, permissive). Consistent with prior research, parental reliance on authoritarian strategies was positively associated with children's level of overt aggression, especially among boys. There was also a trend towards a positive association between authoritarianism and relational aggression among both boys and girls. In addition, this study is the first to show a positive association between maternal permissiveness and relational aggression. This association appears to be specific to relational, and not overt aggression, and emerge more strongly for girls than boys. The implications of these results for understanding the developmental underpinnings of relational aggression are discussed.
