Not only are the effects of bullying long lasting, but they build over time. ABC News reports that according to a study that questioned thousands of children and their parents through key school grades. Bullying can create a very deep wound and continued bullying is more painful for the child and the pain lasts a lot longer if they're bullied in more than one grade. Laura Bogart, of Boston Children's Hospital, with what's considered to be one of the first studies to follow children from grade school to middle school in examining the psychological and physical effects of bullying says a full 45 percent of tenth-graders who were bullied in both the past and the present had the worst psychological health. Bogart says the key is to act now and there is a very strong argument for early intervention.
