职业价值观在肿瘤科护士压力负荷和专业生活品质间的中介效应

Mediating effect of professional values on stress overload and professional quality of life in oncology nurses

目的探讨肿瘤科护士的职业价值观在其压力负荷与专业生活品质间的中介效应。方法采用便利抽样法,以北京市2家肿瘤专科医院544名肿瘤科护士为研究对象,使用一般资料调查表、压力负荷量表、护士职业价值观量表修订版和中文版专业生活品质量表进行问卷调查并对数据进行相关分析。采用AMOS 21.0软件建立结构方程模型进行中介效应验证。结果肿瘤科护士压力负荷得分为48.00(36.00,62.00)分;职业价值观得分为102.00(86.25,110.00)分;专业生活品质中的同情心满意得分为36.00(31.00,41.00)分,职业倦怠得分为22.00(17.00,26.00)分,二次创伤得分为22.00(19.00,26.00)分。肿瘤科护士压力负荷与职业价值观呈负相关,压力负荷与同情心满意呈负相关,与职业倦怠、二次创伤呈正相关(P<0.05)。结构方程拟合指数(CMIF/DF)=0.430,拟合优度指数(GFI)=1.000,调整拟合优度指数(AGFI)=0.995,近似误差均方根(RMSEA)=0.000。肿瘤科护士的压力负荷和职业价值观对其专业生活品质具有直接预测作用,压力负荷以职业价值观为中介变量,间接影响同情心满意和职业倦怠。结论护理管理人员可通过降低肿瘤科护士的压力负荷提升其职业价值观,改善其专业生活品质。

Objective To explore the mediating effect of professional values on the stress overload and professional quality of life in oncology nurses.Methods Using the convenient sampling method,a total of 544 oncology nurses from 2 cancer hospitals in Beijing were selected as the research objects.General data questionnaire,Stress Overload Scale(SOS),The Nurses Professional Values Scale-Revised(NPVSR),revised version of Nurses Professional Values Scale and Chinese version of Professional Quality of Life Scale were used for questionnaire survey and correlation analysis of the data.AMOS 21.0 software was used to establish a structural equation model to verify the mediating effect.Results The stress overload score of oncology nurses was 48.00(36.00,62.00),and the professional values score was 102.00(86.25,110.00).The compassion satisfaction score for professional quality of life was 36.00(31.00,41.00),the burnout score was 22.00(17.00,26.00),and the secondary traumatic stress score was 22.00(19.00,26.00).The stress overload of oncology nurses was negatively correlated with professional values,negatively correlated with compassion satisfaction,and positively correlated with job burnout and secondary traumatic stress(P<0.05).Structural equation fitting index(CMIF/DF)was 0.430,goodness of fit index(GFI)was 1.000,adjusted goodness of fit index(AGFI)was 0.995 and root mean square error of approximation(RMSEA)was 0.000.The stress overload and professional values of oncology nurses had a direct predictive effect on their professional quality of life.The stress overload was mediated by professional values,which indirectly affected compassion satisfaction and job burnout.Conclusions Nursing managers can enhance their professional values and improve their professional quality of life by reducing the stress overload on oncology nurses.
