RESUMO
This study examined adolescent narcissism, temperament (frustration and affiliation), and social goals in association with peer-reported physical and relational aggression (N = 384; 12-14 years). Narcissism was positively associated with dominance goals and negatively with closeness goals for peer interaction. Moreover, narcissism was positively associated with physical aggression via dominance goals for boys, and with relational aggression via dominance goals for both genders. Temperamental frustration and affiliation were both positively associated with relational aggression, but also interacted in their associations with this variable; affiliation was positively associated with relational aggression only at high levels of frustration. Supporting and extending existing research, the present findings suggest that adolescent personality and social goals are meaningfully associated with physical and relational aggression in the peer context.
