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 less than 0.001). 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. (Contains 3 tables. Scales is appended.)
