Being a victim or perpetrator of school bullying, the most common type of school violence, has been frequently associated with a broad spectrum of behavioral, emotional, and social problems. Suicide is third leading cause of mortality in children and adolescent in the United States of America and around the world. This paper provides a systematic review of the previous 37 studies conducted in children and adolescents from communities, as well as in special populations that examined the association between bullying experiences and suicide, with an emphasis on the strengths and limitations of the study designs. Despite methodological and other differences and limitations, it is increasingly clear that any participation in bullying increases the risk of suicidal ideations and/or behaviors in a broad spectrum of youth.
