Book excerpt: Bullying, particularly among school-age children, is a major public health problem both domestically and internationally (Nansel, Craig, Overpeck, Saluja, & Ruan, 2004). Current estimates suggest that nearly 30% of American adolescents reported at least moderate bullying experiences as the bully, the victim, or both. Specifically, of a nationally representative sample of adolescents, 13% reported being a bully, 11% reported being a victim of bullying, and 6% reported being both a bully and a victim (Nansel et al., 2001).
