In particular, we examined the mediating role of cognitive and affective empathy on the relation between parental attachment and bystander help-seeking in 826 adolescents in the 6th and 9th grade (49.9% female) using four bullying/acts of aggression scenarios. Results indicated that affective, but not cognitive, empathy served as a partial mediator for the relationship in boys, suggesting that both empathy and the family context can play a role in bystander decisions to intervene. On the other hand, empathy did not serve as a mediator for girls, suggesting that girls do not need the added push of empathy in order to intervene in bullying situations. Results suggest emphasizing home-school collaboration for boys, in particular, in bullying prevention programs in order to maximize efforts of bystanders. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.EnglishAdolescentsBullyingBystander interventionEmpathyParental attachmentArticle10.1007/s10826-022-02312-2
