cyberbullying research center   "As you know, Japan has very bad bullying. Cyber bullying, physical bullying, and mental abuse bullying. We have a very high rate of suicide attempts at the age bracket of middle school kids to high school kids. This is a story about a best friend I had who committed suicide right in front of me. And all it started was a crush she had, it was such a small thing. All she wanted to do is have a normal teenage life; that never happened. She wanted to join in the group but everyone called her "gloomy, sullen, creepy." It wasn't very nice at all. The tone of their voices changed when she came in the room, there were thumbnails in her shoes, dead animals in her desk, and many more. There were also a lot of hate mail. Sometimes just to ease the pain I deleted the mails before she could even see them, but that didn't do much good. I wish I could've helped more... Every day I saw her eyes die and become darker and darker. It was the time when I was going home with her and we were waiting for the train to pass by; it was that time when she just pushed me away and ran in front of the tracks and committed suicide. Now it has been 3 years since she did this act, I still regret not saving her, I still regret everything I could not have done." (16 year-old girl from Japan)

Fact Sheet
Cyberbullying and Suicide

By Sameer Hinduja, Ph.D. and Justin W. Patchin, Ph.D.

Youth suicide continues to be a significant public health concern in the United States.  Even though suicide rates have decreased 28.5 percent among young people in recent years, upward trends were identified in the 10- to 19-year-old age group (Centers for Disease Control and Prevention, 2007).  In addition to those who successfully end their life, many other adolescents strongly think about and even attempt suicide. 

One factor that has been linked to suicidal ideation is experience with bullying.  That is, youth who are bullied, or who bully others, are at an elevated risk for suicidal thoughts, attempts, and completed suicides (Rigby & Slee, 1999; van der Wal, de Wit, & Hirasing, 2003).  The reality of these links has been strengthened through research showing how experience with peer harassment (most often as a target but also as a perpetrator) contributes to depression, decreased self-worth, hopelessness, and loneliness – all of which are precursors to suicidal thoughts and behavior (Hawker & Boulton, 2000; Joiner & Rudd, 1996; Kaltiala-Heino, Rimpela, Rantanen, & Rimpela, 2000).

Without question, the nature of adolescent peer aggression has evolved due to the proliferation of information and communications technology.  There have been several high-profile cases involving teenagers taking their own lives in part because of being harassed and mistreated over the Internet (Apollo, 2007; Halligan, 2006; Jones, 2008), a phenomenon we have termed cyberbullicide – suicide indirectly or directly influenced by experiences with online aggression (Hinduja & Patchin, 2009).  While these incidents are isolated and do not represent the norm, their gravity demands deeper inquiry and understanding.  Much research has been conducted to determine the relationship between traditional bullying and suicidal ideation, and it can be said with confidence that a strong relationship exists (Kim, Koh, & Leventhal, 2005; Roland, 2002).  Based on what we found in the extant literature base, we sought to determine if suicidal ideation was also linked to experiences with cyberbullying among offenders and targets.   


In our recent research involving approximately 2,000 randomly-selected middle-schoolers from one of the most populous school districts in the United States, 20% of respondents reported seriously thinking about attempting suicide (19.7% of females; 20.9% of males), while 19% reported attempting suicide (17.9% of females; 20.2% of males).  This is comparable to other studies focusing on adolescent populations (Langhinrichsen-Rohling & Lamis, 2008).  With regard to traditional bullying, prevalence rates for individual behaviors ranged from 6.5% to 27.7% for offending and from 10.9% to 29.3% for victimization.  The most common form of bullying offending reported by respondents was: “I called another student mean names, made fun of or teased him or her in a hurtful way” (27.7%), while the most frequently-cited form of bullying victimization was: “Other students told lies or spread false rumors about me and tried to make others dislike me (29.3%).  With regard to cyberbullying, prevalence rates for individual behaviors ranged from 9.1% to 23.1% for offending and from 5.7% to 18.3% for victimization.  The most commonly-reported form of cyberbullying offending was: “Posted something online about another person to make others laugh” (23.1%) while the most frequent form of victimization was: “Received an upsetting email from someone you know” (18.3%). 

With respect to bullying, all forms were significantly associated with increases in suicidal ideation among sample respondents.  That is, youth who experienced traditional bullying or cyberbullying, as either an offender or a victim, scored higher on our suicidal ideation scale than those who had not experienced those two forms of peer aggression.  Moreover, it appears that bullying and cyberbullying victimization was a stronger predictor of suicidal thoughts and behaviors than was bullying and cyberbullying offending

Finally, we wanted to see if bullying and cyberbullying experiences were related to an increased likelihood of an adolescent attempting suicide.  Results showed that all forms of peer aggression increased the likelihood that the respondent attempted suicide.  Traditional bullying victims were 1.7 times more likely and traditional bullying offenders were 2.1 times more likely to have attempted suicide than those who were not traditional victims or offenders.  Similarly, cyberbullying victims were 1.9 times more likely and cyberbullying offenders were 1.5 times more likely to have attempted suicide than those who were not cyberbullying victims or offenders. 

Highlights from the Research:

  • 20% of respondents reported seriously thinking about attempting suicide
  • All forms of bullying were significantly associated with increases in suicidal ideation
  • Cyberbullying victims were almost twice as likely to have attempted suicide compared to youth who had not experienced cyberbullying 


The small but significant variation found in suicidal thoughts and actions based on bullying and cyberbullying suggests that all forms of adolescent peer aggression must be taken seriously - both at school and at home.  As such, psychologists, counselors, and parents must continually monitor the online and offline behaviors of youth to reinforce the good and regulate the bad.  In addition, the findings suggest that a suicide prevention and intervention component is essential within comprehensive bullying response programs implemented in schools.  Without question, the topic is sensitive and its presentation should be age-appropriate, as students in all grade levels must understand the serious consequences associated with peer aggression.  While suicide is an extreme response, proper discussion of its stark reality can vividly portray the extent of harm that peer harassment can exact. 

It should be acknowledged that many of the teenagers who committed suicide after experiencing bullying or cyberbullying had other emotional and social issues going on in their lives. For example, one cyberbullicide victim attended special education classes in elementary school and struggled socially and academically (Flowers, 2006). Another suffered from low self-esteem and depression and was on medication when she took her life (Zetter, 2008).  As mentioned earlier, it is unlikely that experience with cyberbullying by itself leads to youth suicide.  Rather, it tends to exacerbate instability and hopelessness in the minds of adolescents already struggling with stressful life circumstances (Hinduja & Patchin, 2009).  Future research should identify and specifically assess the contributive nature of these stress-inducing experiences.

What They're Saying...
"The workshop on Cyberbullying offered at NAU was informative and timely. I work with 7th and 8th graders, and "drama" is a very big part of their lives. You gave me tools that I will share with them so that they may be safe as they travel the cyber highway. The format of the workshop was refreshing. We were treated as professionals with respect and dignity, the opportunity to ask questions and share some experiences was very valuable." Wilma Robillard-Hoffman, Middle School Teacher, Mohave Valley School District
