Bulling is related with emotional and behavioral problems.

To investigate the behavioral characteristics of pure bullies, pure victims, bully/victims, pure witness and children with no involvement.

Subjects were 112 children (6–13 years old). They completed questionnaire regarding acting the bully, being bullied and seeing someone bullied (Bully-victim-witness questionnaire). The questionnaire includes 5 psychological bully questions, 5 being bullied and 5 seeing bullies, respectively. Their parents completed the Child Behavior Checklist (CBCL).

112 children were divided into pure bullies (n = 12), pure victims (n = 30), bully/victims (n = 40), pure witnesses (n = 9) and children who were not involved (n = 21). The figure shows the mean scores of CBCL of pure bullies, pure victims, bully/victims and pure witnesses. The mean CBCL (withdrawal, social problems, attention and aggression) scores of bully/victims were higher than other groups.

We have to pay attention to the behavior problems of bully/victims, and the children with behavioral problems should be concerned about bullying problems.
