Bullying at school-an indicator of adolescents at risk for mental disorders

A number of 14-16 year old Finnish adolescents taking part in the School Health Promotion Study (n=8787 in 1995, n=17643 in 1997) were surveyed about bullying and victimization in relation to psychosomatic symptoms, depression, anxiety, eating disorders and substance use. A total of 9 per cent of girls and 17 per cent of boys were involved in bullying on a weekly basis. Anxiety, depression and psychosomatic symptoms were most frequent among bullyvictims and equally common among bullies and victims. Frequent excessive drinking and use of any other substance were most common among bullies and thereafter among bully-victims. Among girls, eating disorders were associated with involvement in bullying in any role, among boys with being bully-victims. Bullying should be seen as an indicator of risk of various mental disorders in adolescence.
