欺负与护士自尊、健康及工作绩效关系

Relationship between workplace bullying,self-esteem,health and job performance among nurses

目的探讨工作场所中欺负与护士自尊、健康和工作绩效的关系,为阐明欺负的作用机制及其干预提供理论依据。方法采用分层随机抽样方法在广西南宁抽取6所医院450名护士进行问卷调查。结果相关分析表明,欺负与自尊、健康和工作绩效均呈负相关关系(r=-0.179、-0.314、-0.139,P<0.01);回归分析表明,欺负能负向预测个体的自尊、健康和工作绩效(β=-0.176、-0.312和-0.147,P<0.01);进一步的结构方程模型分析表明,欺负对个体健康水平具有直接效应(γ=-0.316,P<0.01),并部分通过自尊影响个体健康水平(P<0.01),中介效应为-0.153(P<0.01);欺负对工作绩效的直接效应无统计学意义(P>0.05),而是完全通过自尊影响个体工作绩效(P<0.05),中介效应为-0.134(P<0.05)。结论自尊在欺负与健康之间具有部分中介效应,在欺负与工作绩效之间具有完全中介效应。

Objective To investigate the relationship between workplace bullying,self-esteem,health and job performance among nurses.Methods With stratified random sampling,450 nurses from six hospitals in Nanning of Guangxi were investigated with a workplace bullying questionnaire,self-esteem scale,general health questionnaire and job performance questionnaire.Results Bullying had significant negative correlations with self-esteem,health and job performance（r=-0.179,-0.314,-0.139;P〈0.01 for all）.Bullying negatively influenced the nurses＇ self-esteem,health and job performance（β=-0.176,-0.312,-0.147;P〈0.01 for all）.Structural equation model showed that bullying could either directly affect health or produce indirect effects on health and job performance via self-esteem,with the mediating effect of-0.153（P〈0.01）and-0.134（P〈0.05）,respectively.Conclusion Partial mediation effect of self-esteem on the relationship between bullying and health is significant and the complete mediation effect of self-esteem on the relationship between bullying and job performance is also significant.
