Workplace bullying and suicidal ideation: A 3-wave longitudinal Norwegian study
Nielsen, M.B., Nielsen, G.H., Notelaers, G., & Einarsen, S.
We examined whether victimization from bullying is related to an increased risk of suicidal ideation over time and whether suicidal ideation is related to subsequent bullying.
In a longitudinal study (2005-2010), we used well-established single-item measures to assess victimization from bullying and suicidal ideation. We used latent Markov models to determine forward and reverse relationships between variables at 3 time points with 2 or 3 years between the measurement points among a randomized nationwide sample of 1846 employees in Norway.
Victimization from bullying was associated with subsequent suicidal ideation (odds ratio = 2.05; 95% confidence interval = 1.08, 3.89). Suicidal ideation at baseline was not related to subsequent victimization from workplace bullying.
Workplace bullying may be a precursor to suicidal ideation, whereas suicidal ideation seems to have no impact on subsequent risk of being bullied. Regulations against bullying should be integrated into work-related legislation and public health policies.
