Bullying Has Negative Consequences For All Involved

Bullying is an unwanted aggressive behavior characterized by repetition (i.e., it is repeated or has a high likelihood of being repeated), and a power imbalance that is observed or perceived (i.e., youth bullying others have more physical and/or social power than bullied youth). The behavior is intentional and can result in harm or distress.Gladden, R.M., Vivolo-Kantor, A.M., Hamburger, M.E. & Lumpkin, C.D. Bullying Surveillance Among Youths: Uniform Definitions for Public Health and Recommended Data Elements, Version 1.0. Atlanta, GA: National Center for Injury Prevention and Control, Centers for Disease Control and Prevention and U.S. Department of Education; 2014. Bullying behavior can be physical (e.g., hitting), verbal (e.g., name calling either oral or written), relational (e.g., spreading rumors), or via property damage. Every year about 21 percent of U.S. middle- and high-school students are victims of bullying.U.S. Department of Justice, Bureau of Justice Statistics, School Crime Supplement (SCS - Version 1) to the National Crime Victimization Survey, 2015.

Past research suggests a dose-response relationship between bullying victimization and behavioral health outcomes.Evans, C. B. R., Smokowski, P. R., & Cotter, K. L. (2014). "Cumulative bullying victimization: An investigation of the does-response relationship between victimization and the associated mental health outcomes, social supports, and school experiences of rural adolescents. " Children and Youth Services Review, 44: 256-264. In other words, increased exposure to bullying victimization – over time and experiencing multiple types of bullying – is associated with progressively worse behavioral health outcomes among bullied youth. This is potentially also true for bullying perpetration – the more a youth bullies others over time, the more likely they could be of engaging in a lifestyle of violence and aggression.Loeber, R. & Burke, J. D. (2011). "Developmental pathways in juvenile externalizing and internalizing problems." Journal of Research on Adolescence, 21(1): 34-46., Farrington, D. & Baldry, A. (2010). "Individual risk factors for school bullying." Journal of Aggression, Conflict and Peace Research, 2(1): 4-16. Yet, limited research has examined the cumulative impact of being a bystander to bullying on youth’s health and well-being.

We recently conducted a studyEvans, C. B. R., Smokowski, P. R., Rose, R. A., Mercado, M. C., & Marshall, K. J. (2018). "Cumulative bullying experiences, adolescent behavioral and mental health, and academic achievement: An integrated model of perpetration, victimization, and bystander behavior." Journal of Children and Family Studies. [Online first] doi: 10.1007/s10826-018-1078-4. to learn more about the relationship between cumulative bullying experiences over 2-5 years, and different types of youth outcomes among over 6,000 rural middle- and high-school youth in North Carolina. Distinct from prior research, this study integrated different bullying roles (i.e., victimization, perpetration, bystander) with behavioral, mental health, and academic domains of adolescent functioning. We found that cumulative bullying involvement over time – either as the one who bullies, the one who is bullied, or a bystander – resulted in multiple negative outcomes for the youth. Specifically . . .

• Youth who are bullied: Cumulative bullying victimization was significantly associated with increased levels of aggression and internalizing symptoms (e.g., depression, anxiety), and decreased levels of self-esteem and future optimism.
• Youth who bully others: Cumulative bullying perpetration was significantly associated with increased levels of aggression, and decreased levels of future optimism.
• Bystanders who help the youth who bullies: Cumulative negative bystander behavior (e.g., laughing at the perpetrator’s behavior, joining in the bullying) was significantly associated with increased aggression and internalizing symptoms, and decreased academic achievement and future optimism.
• Bystanders who help the youth being bullied: Cumulative prosocial bystander behavior (e.g., directly confronting the perpetrator, getting a teacher) was significantly associated with increased levels of depression and anxiety, as well as higher academic achievement, self-esteem, and future optimism. This might mean that while these bystanders felt good about helping, they also worried about being bullied next.

Being a perpetrator, victim, or negative bystander to bullying is particularly problematic for students’ wellbeing. To reduce negative consequences for all students involved, it is important to expand efforts to prevent and decrease bullying before the negative effects accumulate over time. Examples of prevention strategies and approaches based on the best available evidence can be found in CDC’s Youth Violence Prevention Technical Package.David-Ferdon, C., Vivolo-Kantor, A. M., Dahlberg, L. L., Marshall, K. J., Rainford, N. & Hall, J. E. A Comprehensive Technical Package for the Prevention of Youth Violence and Associated Risk Behaviors. Atlanta, GA: National Center for Injury Prevention and Control, Centers for Disease Control and Prevention; 2016. It is also important to teach youth to be "upstanders" – that is, to stand up as prosocial bystanders to aid those being bullied, while garnering benefits for their own health and well-being.
