Workplace violence and burnout among Chinese nurses during the COVID-19 pandemic: does the sense of coherence mediate the relationship?

backgroundWorkplace violence has always been a critical issue worldwide before and after the COVID-19 pandemic, which can lead to burnout and turnover. In addition, the burnout and mental stress of nurses during the COVID-19 period have been widely described. To our knowledge, no studies have examined the mediating effect of the sense of coherence on the relationship between workplace violence and burnout among Chinese nurses over time. Therefore, this study aimed to explore the relationship between workplace violence and burnout among Chinese nurses and how the sense of coherence mediates the association.

methodsUsing a convenience sampling method, 1190 nurses from 4 tertiary grade-A comprehensive hospitals were investigated between September 2021 and December 2021 in 3 provinces of China. The Workplace Violence Scale, Burnout Inventory, and Sense of Coherence scale were used to collect data. Data analysis was conducted using descriptive statistics, Pearson correlation, and regression analysis to estimate direct and indirect effects using bootstrap analysis.

resultsThe mean total scores for workplace violence and burnout were 1.67 ± 1.08 and 47.36 ± 18.39, respectively. Workplace violence was significantly negatively correlated with the sense of coherence (r = -0.25) and positively correlated with burnout (r = 0.27). Additionally, a higher level of workplace violence was associated with higher burnout (β = 1.13, 95% CI: 0.68 ~ 1.56). A higher sense of coherence was also associated with lower burnout (β = -0.98, 95% CI: -1.03 ~ -0.92). Workplace violence showed an effect on burnout through a sense of coherence. The direct, indirect and total effects were 1.13, 1.88 and 3.01, respectively. The mediating effect of the sense of coherence accounted for 62.45% of the relationship between workplace violence and burnout.

conclusionWe found that the sense of coherence mediated most workplace violence on burnout. It is imperative for hospital managers to improve nurses' sense of coherence to reduce the occurrence of burnout during COVID-19. Future intervention studies should be designed to strengthen nurses' sense of coherence.
