Prevalence of workplace bullying in Norway: Comparisons across time and estimation methods

This study investigates the prevalence of exposure to workplace bullying in a representative sample of 2539 Norwegian employees utilizing different measurement and estimation methods. The prevalence of workplace bullying varied from 2 to 14.3% depending on method of measurement and estimation. Latent class cluster analysis is concluded to give the most reliable estimate (6.8%). Compared to a similar Norwegian study published in 1996, the prevalence of self-reported victimization from bullying is considerably reduced; from 8.6% in the early 1990s to 4.6% in 2005. In the 1996 study, 4.6% labelled themselves as victims of severe bullying, the corresponding number being 2% in 2005.
