I don't have specific answers to that, but I think it could be related to exposure to vulnerable situations, such as being mentored or in situations where perpetrators could be a coach, or a teacher, or whatever. That could certainly be related. I don't know, there might be a way of doing cross-tabulation to see if the type of relationship of the perpetrator with the victim could be one way to answer this question.
