Testing the Normative Hypothesis of Relational Aggression and Psychopathology through Gender and Age Moderation

The gender normative hypothesis of relational aggression and psychopathology states that relational aggression is more detrimental to boys than it is to girls because relational aggression is more normative in girls. In the present study, this hypothesis was tested in a large sample of 6-to-18-year-old children and this hypothesis was also extended to the domain of age norms. Specifically, it was tested whether relational aggression would also be most detrimental outside of the age in which it is most normative. The results showed some evidence supporting the gender normative hypothesis. Specifically, it was found that relationally aggressive boys suffered more internalizing and externalizing problems than non-relationally aggressive boys did. Relationally aggressive girls, however, suffered only more externalizing problems than non-relationally aggressive girls did. Results did not support the age normative hypothesis. Implications of these findings and future directions are discussed.MAS
