Estimates of American children who report being repeatedly victimized by their peers have ranged from 10% to 30%(Grills & Ollendick, 2002; Nansel et al., 2001). The occurrence of peer victimization is alarming when one considers the negative psychological and physical consequences of being bullied (Kupersmidt, Coie, & Dodge, 1990; Miller & Vaillancourt, 2007). The negative outcomes of peer victimization are long-lasting; as adults, adolescents who were victimized experience more depression and lower self-esteem than those not victimized (Bagwell, Newcomb, & Bukowski, 1998; Olweus, 1978). In addition, victimized adolescents experience more frequent and severe health problems than do nonvictimized adolescents, even three years later (Greco, Freeman, & Dufton, 2007; Rigby, 2003).
