Bullying is a malicious aggressive behavior that is intended to harm others repeatedly. There is an imbalance in strength or power between the bullies and the victims of bullying. Studies in European countries and U.S. suggest that 20% to 30% of students are frequently involved in bullying as bullies and/or victims. Cross-sectional and longitudinal studies have recognized bullying and being victimized by bullies as health problems for school children and adolescents because of their association with a range of adjustment problems, including poor mental health and violent behavior. Bully-victims, who are involved in both bullying others and being bullied by others, have the greatest number of mental and behavioral problems. Children needing special health care are especially vulnerable to being bullied. The signifi cant association between involvement in bullying and adverse mental health in children and adolescents indicates that the early identifi cation of and intervention on children and adolescents at risk should be a priority for the society. |
