ABSTRACT
OBJECTIVE: To examine if perceived stress mediated the association between workplace bullying and subsequent long-term sickness absence. METHODS: The PRISME cohort was established in 2007 and re-examined in 2009. Questionnaire data about workplace bullying and perceived stress were obtained from 4114 individuals. Participants were followed in registers on long-term sickness absence (≥30 consecutive days of sickness absence). RESULTS: Workplace bullying was associated with subsequent sickness absence (odds ratio [OR]â=â2.05; 95% confidence interval [CI]: 1.57 to 2.65) and concurrent high perceived stress levels (ORâ=â2.34; 95% CI: 1.86 to 2.96). A high perceived stress level was also associated with subsequent sickness absence (ORâ=â1.33; 95% CI: 1.13 to 1.56). Perceived stress explained 13% (95% CI: 6 to 23%) of the total association between bullying and sickness absence. CONCLUSIONS: The association between workplace bullying and subsequent long-term sickness absence may be partially mediated by perceived stress.
