“…Children who experienced high levels of victimization (once or more per week) were rated by their parents as having higher levels of anxiety, hyperactivity, self-injurious and stereotypic behaviors, and over sensitivity than children who experienced no victimization or experienced low levels of victimization (i.e., less than once per week). These findings are consistent with international bullying literature, which indicates that children who are victimized are more likely than peers to exhibit various internalizing and externalizing mental health problems (Delfabbro et al, 2006;Grills & Ollendick, 2002;Haynie et al, 2001;Mitchell, Ybarra, & Finkelhor, 2007;Nansel et al, 2001Nansel et al, , 2003Nansel et al, , 2004Ybarra & Mitchell, 2004. Victimization is stressful for Bullying 16 children and negatively impacts self-concept, both of which are associated with mental health problems (Grills & Ollendick, 2002;Marsh, Parada, Yeung, & Healey, 2001;Nansel, 2004;O'Moore & Kirkham, 2001).…”
