摘要目的:探讨手术室护士心理资本在体面劳动感与工作投入间的中介作用，为提升手术室护士工作投入提供借鉴和参考。方法:采用便利抽样法，于2023年12月—2024年2月选取北京市、重庆市、大连市和珠海市4所三甲医院的307名手术室护士为研究对象，采用一般资料调查表、工作投入量表、体面劳动量表及护士心理资本量表进行调查。采用Pearson相关分析探讨手术室护士的心理资本、体面劳动感与工作投入间的相关性，采用AMOS 24.0软件建立结构方程模型并分析中介效应。结果:共发放307份问卷，回收有效问卷301份，有效回收率为98.05%。301名手术室护士工作投入、体面劳动感及心理资本得分分别为（41.01±10.76）、（67.30±17.86）、（93.30±15.15）分；工作投入与体面劳动感、心理资本总分呈正相关（均 P<0.01），体面劳动感与心理资本呈正相关（ P<0.01）；心理资本在体面劳动感与工作投入间起部分中介作用，中介效应占比为62.63%。 结论:手术室护士心理资本在体面劳动感与工作投入间起部分中介作用。护理管理者可以通过提升手术室护士体面劳动感及增强护士心理资本，从而提高手术室护士的工作投入。

abstractsObjective:To investigate the mediating role of psychological capital between the perception of decent work and work engagement among Operating Room nurses, and to provide insights for improving their work engagement.Methods:From December 2023 to February 2024, a total of 307 Operating Room nurses from four class ⅢGrade A hospitals in Beijing, Chongqing, Dalian, and Zhuhai were recruited using convenience sampling. Data were collected using a general information questionnaire, Work Engagement Scale, Decent Work Scale, and Nurses' Psychological Capital Scale. Pearson correlation analysis was conducted to examine the relationships among psychological capital, perception of decent work, and work engagement. Structural equation modeling and mediation analysis were performed using AMOS 24.0 software.Results:A total of 307 questionnaires were distributed, and 301 valid responses were collected, with an effective response rate of 98.05%. The mean scores for work engagement, perception of decent work, and psychological capital were (41.01±10.76), (67.30±17.86), and (93.30±15.15), respectively. Work engagement was positively correlated with both the perception of decent work and psychological capital (all P<0.01), and the perception of decent work was positively correlated with psychological capital ( P<0.01). Psychological capital partially mediated the relationship between the perception of decent work and work engagement, with the mediating effect accounting for 62.63%. Conclusions:Psychological capital plays a partial mediating role between the perception of decent work and work engagement among Operating Room nurses. Nursing managers can enhance nurses' work engagement by improving their perception of decent work and strengthening their psychological capital.
