Current estimates suggest who bully others tend to exhibit other defiant that nearly 30% of American adolescents reported and delinquent behaviors, have poor school at least moderate bullying experiences as the bully, performance, be more likely to drop-out of school, the victim, or both. Specifically, of a nationally and be more likely to bring weapons to school representative sample of adolescents, 13% reported (e.g., Berthold & Hoover, 2000; Nansel et al., 2003; being a bully, 11% reported being a victim of Nansel et al., 2004; Sourander, Helstela, Helenius, bullying, and 6% reported being both a bully and a & Piha, 2000). Victims of bullying tend to report victim (Nansel et al., 2001). feelings of depression, anxiety, low self-esteem, How bullying experiences are defined and and isolation; poor school performance; suicidal measured, however, varies greatly. Much of the ideation; and suicide attempts (e.g., Bond, Carlin, work on bullying has adopted the definition Thomas, Ruin, & Patton, 2001; Eisenberg, Neumark- of Daniel Olweus, whose work in the 1990s Sztainer, & Perry, 2003; Gladstone, Parker, & Malhi, increased attention on bullying as a research topic. 2006; Hawker & Boulton, 2000; Klomeck, Marrocco, According to Olweus, a person is bullied when Kleinman, Schonfeld, & Gould, 2007; Nansel he or she is exposed repeatedly over time to et al., 2004; Sourander et al., 2000). Evidence negative actions by one or more others, excluding further suggests that people who are the victims cases where two children of similar physical and of bullying and who also perpetrate bullying (i.e., psychological strength are fighting (Olweus, 1994). bully-victims) may exhibit the poorest functioning, Olweus added that bullying can be direct (open in comparison with either victims or bullies (e.g., attacks that are physical or verbal in nature) and Nansel et al., 2004). Emotional and behavioral indirect (exclusion). Since the 1990s, researchers problems experienced by victims, bullies, and bully- have modified Olweus’ definition of bullying, for victims may continue into adulthood and produce example, to assess the difference in power between long-term negative outcomes, including low self- bullies and victims (e.g., Vaillancourt, Hymel, & esteem and self-worth, depression, antisocial McDougall, 2003). Regarding measurement, some behavior, vandalism, drug use and abuse, criminal scholars provide respondents with a definition behavior, gang membership, and suicidal ideation of bullying similar to Olweus’ definition (e.g., (e.g., Nansel et al., 2001; Gladstone et al., 2006; Nansel, Overpeck, Haynie, Ruan, & Schiedt, Hugh-Jones & Smith, 1999; Olweus, 1994). 2003) before inquiring about their experiences In the bullying literature, the experiences of with bullying, while others measure bullying by bystanders—that is, individuals who watch providing behaviorally specific questions, such bullying happen or hear about it—have largely as the frequency of name-calling or hitting (e.g., been overlooked (Twemlow, Fonagy, & Sacco, Bosworth, Espelage, & Simon, 1999). 2004). What is known is that youth who witness Despite the variability in the literature, scholars bullying often report increased feelings of guilt agree that bullying experiences include not only or helplessness for not confronting the bully physical aggression, but also verbal aggression, and/or supporting the victim (Hoover, Oliver, & including verbal harassment, spreading rumors, or Hazler, 1992; O’Connell, Pepler, & Craig, 1999). social rejection and isolation. Moreover, research Additionally, adolescent bystanders may separate suggests that boys are more likely to engage in themselves from a bullied peer to avoid being physical aggression, while verbal aggression, often bullied (Salmivalli, 2001). called relational aggression, is more common among girls (e.g., Baldry & Farrington, 2000; Nansel et al., 2001; Rivers & Smith, 1994). 1 Purpose of the Compendium among adolescents and young adults. These This compendium provides researchers, terms were used to conduct searches of multiple prevention specialists, and health educators with electronic databases, which yielded a variety of tools to measure a range of bullying experiences: different measures and scales. bully perpetration, bully victimization, bully- We used the following inclusion criteria: victim experiences, and bystander experiences. • To maximize inclusiveness of our review of Some researchers continue to examine the measures, we included a measure if the article in risk and protective factors associated with which it was published referred to the construct bullying experiences.
