Bullying is a harmful behavior that affects many students. In light of Bullying Prevention Month, here are some fast facts on bullying:

  • In the United States, about 1 in 5 students ages 12-18 experienced bullying during the school year.
  • According to the Centers for Disease Control, people who are bullied are more likely to have low self-esteem and to isolate, to perform poorly in school, have few friends at school, have a negative view of school, experience physical symptoms of stress like headache, stomachache, or sleeping problems, and experience mental health problems such as depression, suicidal thoughts, and anxiety.
  • The most common type of bullying is verbal harassment (79%), followed by social harassment (50 percent), and physical bullying (29 percent). Cyberbullying accounts for 25 percent of bullying.
  • Bullying is not only harmful to the person who is bullied, but also the bully and bystanders. Young people who bully others are at a higher risk for substance use, academic problems, and experiencing violence in adolescence and adulthood. People who witness bullying are more likely to use alcohol, tobacco, or other drugs; have increased mental health problems; and miss school.
  • Bystander intervention is powerful. More than half (57%) of bullying incidents stop when a peer intervenes on behalf of the student being bullied. Unfortunately, however, peer bystanders intervene less than 20% of the time. (Hawkins, Pepler, & Craig, 2001).
    • Schools should encourage bystander intervention through teaching anti-bullying skills, offering resources, and ensuring that bystanders are safe. Learn about our courses involving bystander intervention: Consent & Respect and Respect & Resolve
  • Anyone can bully or be bullied, whether they are male or female, whether they are popular or not, or whether they get good grades or not. Many bullies have high self-esteem, but some are victims of bullying themselves. Being a bully is a behavior, not an identity profile. 
    • Labeling a kid as a bully can be harmful because it implies the behavior is fixed and limits their future and ability to change. Empowering students to change is more effective than punishment. Learn more about our intervention course for abusive behaviors: Conflict-Wise
  • Out of students ages 12–18 who reported being bullied at school in 2017, about 46% reported notifying an adult at school about the incident.
  • Bullying and suicide-related behavior are closely related. It’s unclear whether youth with depression and anxiety are more likely to be involved in bullying, whether bullying causes poor mental health, or both. While most youth who are involved in bullying do NOT engage in suicide-related behavior, involvement in bullying, along with other risk factors, increases the risk of a young person engaging in suicide-related behaviors.

What Works: Effective Prevention Involves Everyone

Stopping bullying calls for students, parents, teachers, and community members to get involved. Community-wide efforts address bigger issues that can contribute to bullying and shows kids who are bullied that they are not alone. Rather than zero-tolerance policies which have inconsistent results, programs that emphasize prevention, identification of students with concerning behavior, and skills training like socio-emotional learning have success in reducing bullying behaviors (Swearer, Wang, Collins, Strawhun, & Fluke, 2014)

The Centers for Disease Control recommends schools:

  • Promote family environments that support healthy development, such as parent skill programs
  • Provide quality education in early life
  • Strengthen youth’s skills
  • Connect youth to caring adults and activities, like mentorship by positive role models and extracurriculars
  • Create protective community environments where students feel safe
  • Intervene to lessen harms and prevent future risk
