[email protected]. MIDDLE-SCHOOL GIRLS’ BEHAVIORAL RESPONSES TO OSTRACISM: HOW MUCH DOES INCLUSION COST? Ashley M. Leja 132 Pages Bullying among school-aged children is problematic in the U.S., with 22% of students aged 12-18 years reporting experiences with bullying at school (Zhang, Musu- Gillette, & Oudekerk, 2016). Whereas early bullying research focused heavily on the physical bullying common among boys, more recent studies have included examinations of bullying using relational aggression. Defined as removing or threatening to remove relationships to cause harm to another, relational aggression includes behaviors such as spreading lies, gossiping, or ignoring a peer and has been found to be more common among girls (Crick & Grotpeter, 1995; Cullerton-Sen & Crick, 2005; Murray-Close et al., 2007). A specialized form of relational aggression that has been relatively under investigated among adolescents involves ostracism, the excluding or ignoring of others by individuals or groups (Williams, 2009).
