Abstract: Objective:To explore the mediating role of perceived professional benefit between perceived stress and professional identity so as to provide a theoretical reference for improving professional identity and work enthusiasm of emergency nurses.Methods:320 emergency nurses were selected from 4 tertiary hospitals in Zhengzhou by convenient sampling method. General information questionnaire, perceived stress scale, professional identity scale and perceived professional benefit scale were used to investigate. SPSS 21.0 and AMOS 22.0 software were used for data analysis.Results:314 questionnaires were effectively recycled(98.1%). Perceived stress scale score was（38.89±11.17）, perceived professional benefit scale score was（52.37±9.15）,professional identity scale score was（104.80±9.13）. Perceived stress was negative correlated with perceived professional benefit, and professional identity（P<0.001）; Perceived professional benefit was positive correlated with professional identity（P<0.001）. Perceived professional benefit exerted an intermediary role between perceived stress and professional identity and the mediation effect accounted for 31.2%（-0.243/-0.780） of the total effect.Conclusion:Perceived professional benefit plays an intermediary role between perceived stress and professional identity. Perceived stress mainly affects professional identity through perceived professional benefit.Improving professional benefit of emergency nurses can reduce the perceptive pressure of nurses, so as to improve the professional identity of emergency nurses.
