MINNEAPOLIS, November 25, 2008—An article in The British Journal of Psychiatry suggests that adolescents who experience psychotic symptoms are more likely to have been bullies themselves.

The study's title is "Associations between childhood trauma, bullying and psychotic symptoms among a school-based adolescent sample," and its lead researcher is Ian Kelleher, MSc, of the department of psychiatry at the Royal College of Surgeons in Ireland in Dublin.

The study claims that adolescents with these symptoms are more likely to have been victims of bullying or child abuse earlier in childhood—and more likely to have inflicted violence on others.

Being bullied also increases the likelihood that a child will develop internalizing problems, according to a twin study published in the Archives of Pediatrics & Adolescent Medicine earlier this year.
