Bullying at work and work-related stress in healthcare workers: a cross sectional study

Background: Bullying is a serious and growing problem affecting a significant proportion of healthcare professionals, a professional category exposed to work-related stress. Workplace bullying has been defined as a set of negative behaviours consisting in harassment, offense or negative influence on work that are directed to the members of the organization and that occur regularly and repeatedly over a period, becoming part of the context of work. Study design: We performed a cross-sectional study using the HSE questionnaire and defining the sample size considering the number of healthcare workers of a big hospital and then calculating it with EpiInfo™ software. 191 people have been enrolled. Methods: The study was divided into three steps. The first one to identify, among the workers, those who were exposed to bullying at work and those who were not. The second one has been aimed at assessing the presence of work-related stress through the administration of the HSE questionnaire. The third step has been aimed at performing the statistical analysis of the data. For each single domain explored by the questionnaire the score obtained was treated as a linear variable and the median and interquartile range (IQR) was calculated. After, a non-parametric analysis (Wilcoxon rank-sum test) was performed in order to define the statistical significance of the observed differences. Results: All the 191 questionnaires were self-administered by the Health Care Workers under study and correctly filled in without any multiple or missing responses. Considering the scores obtained to question n. 21, that investigates "bullying at work", we obtained two groups: High-Exposure Group (total, males and females), and Low-Exposure Group (total, males and females). In the High-Exposure Group, two critical domains were found: Demands and Control (total, male and female samples). The differences with the Low-Exposure Group were statistically significant. In the Low-Exposure Group the critical domain was Manager Support (total and female samples). The differences with the High Exposure Group were not statistically significant. Conclusion: This study aimed to show how the exposure to bullying can influence the perception of psychosocial risks. It seems that the workers most exposed to bullying also have worse scores on the HSE questionnaire, particularly for two domains: Demands and Control. That is consistent with the most recent scientific literature
