Abstract: Objective: To explore the status of work engagement, and the effects of organizational justice and organizational support on nurses' work engagement. Methods: A total of 1 065 nurses from 7 hospitals in Beijing were surveyed with a package of questionnaires. Results: The mean score of work engagement was (3.54±1.49), and 21.0% of those subjects showed work engagement at a high level. Structural equation model analysis showed that organizational justice (β=0.536, P<0.01) and organizational support (β=0.289, P<0.01) were positively associated with nurses' work engagement, which could explain 31% variance of nurses' work engagement. And organizational support partly mediated the effect of organizational justice on nurses' work engagement. Conclusion: Clinical nurses' work engagement was at a low level. Managers should perfect nurses' performance evaluation and distribution systems so as to enhance nurses' work engagement through creating a fair and supportive organizational environment.
