It depends on whether the interview is of the bully, or the victim, and also what the purpose of the interview is. For example, are you interviewing students in general to determine if bullying is actually taking place? Or, do you want to find out what types of bullying are going on in your high school? Or, do you want to find out what various opinions are on how to stop bullying?
I think the purpose of the interview would determine the kinds of questions, so I will choose one purpose and give you some sample questions. Let's say you are trying to interview a person who IS a bully. Your purpose is to get that person to realize that he IS a bully and point out to him that his actions are NOT OK and that he is going to be held accountable for them: I would ask things like:
- Have you thought about how your actions or words could have hurt this person's feelings?
- Have you thought about how your actions or words could have harmed this person mentally or physically?
- What makes you think you have the right to say or do things like this to someone else?
- How would you feel if this person did or said these things to you?
- How do you think you could be more sensitive to how your actions are hurting someone else?
- What do you think your parents will say when I tell them what you have said/done to this person? Will they be proud?
- Have you considered that just because this person is different from you or has different beliefs, it is not OK to make fun of him/her or say hurtful things?
- Are you aware of the school's anti-bullying policies? Do you realize you can be suspended or expelled from school for bullying?
- Are you aware that the suicide rate for high school students is very high and that many teens commit suicide as a result of bullying? How would you feel if someone you were mean to committed suicide?
If your purpose is different than this, the questions must be geared to the purpose.
