护士不确定性容忍度在心理控制源和工作投入间的中介作用

Mediating effect of uncertainty tolerance between locus of control and work engagement among nurses

目的:探讨不确定性容忍度在护士心理控制源与工作投入间的中介效应,为临床护理管理与培训提供参考。方法:采用便利抽样法选取四川省成都市、德阳市各2所医院的282名护士为研究对象,采用一般人口学信息调查表调查人口学特征,无法忍受不确定性量表调查不确定性容忍度,内控性、有势力于他人及机遇量表调查心理控制源水平,工作投入量表调查工作投入情况,构建结构方程模型验证不确定性容忍度在护士心理控制源与工作投入间的中介作用。结果:本组护士内控性、有势力于他人、机遇、无法忍受不确定性、工作投入得分分别为(18.27±4.52)分、(23.65±5.80)分、(22.86±5.48)分、(31.27±8.72)分、(54.01±8.58)分,且相互之间存在显著相关性(P<0.01);多元回归分析显示,心理控制源和不确定性容忍度可解释工作投入的41.6%;结构方程模型结果显示不确定性容忍度在心理控制源与工作投入之间存在部分中介效应,中介效应占总效应的44.3%。结论:本组护士心理控制源中内控性占主导,工作投入处于中等水平,不确定性容忍度较低,不确定性容忍度部分介导了心理控制源对工作投入的影响。在护理管理和培训中应关注三者之间的关系,提高护士内控性水平和对不确定事件的认知和应对能力,保证工作投入水平。

Objective To explore the mediating effect of uncertainty tolerance between locus of control and work engagement in nurses,and to provide reference for clinical nursing management and training.Methods A total of 282 nurses from two hospitals in Chengdu and Deyang of Sichuan province were selected as subjects by convenience sampling method.A general demographic information questionnaire was used to investigate demographic characteristics,the intolerance of uncertainty scale was used to investigate uncertainty tolerance,the Internal Control and Powerful over Others and Opportunities Scale was used to investigate the level of sources of psychological control,the Work engagement Scale was used to investigate work engagement,and the structural equation model was constructed to validate the mediating role of uncertainty tolerance in the relationship between nurses'sources of psychological control and work engagement.Results The internality,powerful others,chance,intolerance of uncertainty and work engagement were(18.27±4.52)points,(23.65±5.80)points,(22.86±5.48)points,(31.27±8.72)points,(54.01±8.58)points,respectively.All of them were pairwise correlated(P<0.01).Multiple regression analysis showed that the locus of control and uncertainty tolerance could explain 41.6%of the work engagement.The results of structural equation model showed that the uncertainty tolerance had a partial mediating effect between the locus of control and work engagement,and the mediating effect accounted for 44.3%of the total effect.Conclusions The locus of control can directly and positively affect the nurses'work engagement or indirectly through the mediating effect of uncertainty tolerance.In nursing management and training,we should pay attention to the relationship between the three,improve the internality level of nurses and the cognition and coping ability of uncertain events,and ensure the level of work engagement.
