Impact of job control on hospital workers' safety performance: A moderated mediation analysis of the influences of hospital safety climate and social support

Aim: To improve the level of hospital workers' safety performance in response to emergencies (e.g. COVID-19), this paper examines the relationship between hospital workers' job control on safety performance, and the mediating role of hospital safety climate and the moderating role of social support. Design: In this cross-sectional questionnaire survey, a convenience sampling of hospital workers from three hospitals that have COVID-19 cases from Beijing and Shandong Province in China. Methods: These questionnaires were used to obtain self-reported data on hospital workers' job control, hospital safety climate, social support and safety performance. Mplus software was used to calculate CFA. SPSS25.0 software was used to calculate mean values, standard deviations, correlations and regression analyses. Results: The participants were 241 hospital workers from three hospitals in China (male = 55.2%, female = 44.8%; age range <30 to >45; physician = 58%, nurse = 22%, other hospital worker = 20%). A moderated mediation model among job control, hospital safety climate, social support and safety performance was supported. Moderated mediation analysis indicates hospital workers' job control effectively improves the level of safety performance; hospital safety climate plays a partially mediating role in the process of job control affecting hospital workers' safety performance; social support moderates the effect of work control on medical workers' safety climate. Hence, it is important to increase job control and hospital safety climate. Further, social support for hospital workers should be encouraged, advocated and supported.
