What kind of outcomes can be expected from the Olweus Bullying Prevention Program?

In research studies*, the Olweus Bullying Prevention Program has been shown to:

  • Reduce student reports of being bullied and bullying others by up to 50%. Peer and teacher ratings of bullying problems have yielded roughly similar results.
  • Markedly reduce student reports of general antisocial behavior, such as vandalism, fighting, theft, and truancy.
  • Improve classroom social climate, as reflected in students’ reports of improved order and discipline, more positive social relationships, and more positive attitudes toward schoolwork and school.

* Six large-scale evaluations comparing students randomly assigned to receive the Olweus Bullying Prevention Program to students assigned to not receive the Olweus Bullying Prevention Program.
