Abstract
For medical staff, job satisfaction is essential for advancement on an individual and organizational level. This study looked into the relationships between challenging job demands, job resources, personal resources, and well-being. Additionally, it examined the potential mediating effects of emotional exhaustion and work motivation within the framework of the job demands-resources (JD-R) model. Results from a cross-sectional study of 267 medical employees at a second-grade comprehensive hospital in Jiangsu, China's mainland, indicated that challenging job demands and job satisfaction were positively correlated and mediated via (decreasing) emotional exhaustion. The relationship between job resources and job satisfaction was found to be mediated via (decreasing) emotional exhaustion and (increasing) work motivation. The investigation also demonstrated that the two regulatory focuses serve different purposes. It was discovered that promotion focus had a favorable effect on work motivation but a negative effect on emotional exhaustion. Conversely, preventive focus only positively predicted emotional exhaustion. Thus, the JD-R model offers a valuable structure for clarifying the job satisfaction of health personnel. The implications for enhancing individual and job outcomes are discussed.
