1) The study examined rates of victimization and re-victimization in a national sample of 1467 children over two years.
2) It found high risks of re-victimization, with children experiencing one type of victimization being likely to experience other types as well.
3) "Poly-victims", who experienced four or more types of victimization in a year, faced particularly high risks of persistent poly-victimization and were more likely to show anger/aggression and experience life adversities.
