Adults in charge need to "move away" from the belief bullying is "an inevitable part of growing up" because the long-term repercussions are so severe, according to the authors of a report into the psychological affects of school yard abuse.
Senior author Professor Louise Arseneault, also from the Institute of Psychiatry at King's College, said:
We need to move away from any perception that bullying is just an inevitable part of growing up.
Teachers, parents and policy-makers should be aware that what happens in the school playground can have long-term repercussions for children.
Programmes to stop bullying are extremely important, but we also need to focus our efforts on early intervention to prevent potential problems persisting into adolescence and adulthood.
