Is exposure to domestic violence and violent crime associated with bullying behaviour among underage adolescent psychiatric inpatients?

We examined the relationship of exposure to domestic violence and violence occurring outside home to bullying behaviour in a sample (508; 40.9% males, 59.1% females) of underage psychiatric inpatient adolescents. Participants were interviewed using K-SADS-PL to assess DSM-IV psychiatric diagnoses and to gather information about domestic and other violence and bullying behaviour. Witnessing interparental violence increased the risk of being a victim of bullying up to 2.5-fold among boys. For girls, being a victim of a violent crime was an over 10-fold risk factor for being a bully-victim. Gender differences were seen in witnessing of a violent crime; girls were more likely to be bullies than boys. Further, as regards being a victim of a violent crime outside home and physical abuse by parents at home, girls were significantly more often bully-victims than boys. When interfering and preventing bullying behaviour, it is important to screen adolescents' earlier experiences of violence.
