“…Furthermore, the extant research has primarily focused on one type of social cognitive bias (i.e., hostile attribution bias) and only a handful of studies (e.g., Moon, Morash, & McCluskey, 2012 ; Walters, 2020b ; Walters & Espelage, 2018 ) have examined pathways underlying the association between victimization and bullying perpetration, which is a specific type of aggression that may be associated with worse outcomes for victims (Felix, Sharkey, Green, Furlong, & Tanigawa, 2011 ; Ybarra, Espelage, & Mitchell, 2014 ). Besides hostile attribution bias, victimization is also associated with other maladaptive socio-cognitive factors, such as rumination (e.g., Monti, Rudolph, & Miernicki, 2017 ), that may play a role in whether victimization leads to perpetration. The current study builds on past research by examining whether the prospective association between victimization and bullying is mediated by rumination about past victimization.…”
