Ageing of the population and growth in the burden of noncommunicable disease, together with high turnover among registered nurses (RNs), have widened the gap between supply and demand (Marć et al., 2019;Wu et al., 2016). The shortage of RNs has seriously affected patient outcomes, especially in China. By the end of 2017, the number of RNs in China was about 3.8 million, or 2.74 RNs per 1,000 population (China Health Statistics Yearbook, 2018), which is much lower than the average of 9.2 RNs per 1,000 population in the member countries of the Organisation for Economic Co-operation and Development (OECD) and lower than the proportion in all but one of those 35 countries (Amiri et al., 2020). Because the number of nurses to care for patients cannot easily be increased quickly to a sufficient level, researchers and managers may be able to improve patient care more readily by focusing on other factors related to patient outcomes, notably, work engagement.Recently work engagement among nurses has been paid much strategic attention because of its significant relationship to patient outcomes, nurse outcomes and organisational outcomes (Keyko et al., 2016). Work engagement is defined as 'a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication,
