A bit more than half said they had been laughed at in an unfriendly way, and half reported being called hurtful names. About one third said groups had excluded them to hurt their feelings. 28% said their belongings had been taken or broken; 21% said someone had threatened to hurt them. According to the results, two-thirds of the students said they had been bullied in more than one way over the previous month.
The study authors mentioned that 8% of the students who answered said they had missed school at least once during the school year because of fear of being bullied. 25% said they had taken other actions, such as missing recess, not going to the bathroom or lunch, missing classes, or staying away from some area of the school to escape from experiencing a bully. Bullies did too much to the school life.
