Objective To investigate current situation of resilience of emergency nurses after exposure to workplace violence, and to analyze the influence of coping styles and organizational support on resilience. Methods A total of 1 241 emergency nurses from 6 tertiary hospitals in Shanghai were conveniently sampled and those with exposure to workplace violence in the last one month were screened with the Workplace Violence Frequency Scale. Then positive samples were surveyed using the demographic questionnaire, the Organizational Support Scale，the Trait Coping Style Questionnaire and the Chinese version Resilience Scale for Medical Staff. Results Totally, 749 emergency nurses in the last one month had experienced workplace violence, which predominantly was verbal violence. Those with exposure to workplace violence scored （69.84±12.68） points in resilience. Correlation analysis showed that positive coping style and organizational support were positively correlated with resilience; negative coping style was negatively correlated with resilience (all P<0.05). Multivariate stepwise regression analysis showed that coping styles and organizational support were the main influencing factors of resilience among emergency nurses (both P<0.05). Conclusion Resilience of emergency nurses after exposure to workplace violence needs to be improved, and positive coping style and organizational support have a positive predictive effect on their resilience level. Measures should be taken to improve emergency nurses′ resilience.
