abstract="This school-based study examined the association between bullying and physical and psychological symptoms among adolescents in 28 countries. There is great variation in the prevalence of bullying across countries.  Bullying shows consistent, strong and graded association with each of 12 different physical and pyschological symptoms in all countries.  Effective bullying prevention is needed in many countries and may have important influence on lowering symptom-load among adolescents.",
