Abstract
This paper investigates changes in bullying behaviour among pupils in 72 Norwegian compulsory schools two years after the schools completed an anti‐bullying program. A sample of 22 schools received eight lesson plans with material for staff to use to focus on the challenges of anti‐bullying during this period of two years. Another sample of 22 schools received the same lessons, and also received regular phone calls from a researcher between the lessons. A sample of 28 schools received no other attention than the surveys. We assumed that bullying would be lower in the schools which received follow‐up procedures than in the control schools. Results showed no overall change in mean victimisation scores (i.e., being the victim of bullying), although there was a slight but significant overall decrease in bullying scores (i.e., bullying others) (F = 12.58, p < .001). Our predictions of differences between the samples were not supported. One possible conclusion is that the follow‐up procedures offered were not sufficient to decrease bullying any further. Further research is needed to determine whether the lack of effect is due to the type of follow‐up measure or to implementation within schools.
