心理韧性对精神科医生工作压力与睡眠质量的中介作用

Mediating effect of mental resilience between work stress and sleep quality of psychiatrists

目的分析心理韧性在精神科医生工作压力与睡眠质量间的中介作用。方法采用便利抽样方法,选择陕西省4所精神卫生中心的221名一线精神科医生为研究对象。采用《临床医生工作压力源量表》《心理韧性量表》《匹兹堡睡眠质量指数量表》分别对精神科医生的工作压力、心理韧性和睡眠质量进行调查。采用SPSS PROCESS V3.5宏程序进行Bootstrap中介效应检验分析心理韧性的中介作用。结果精神科医生工作压力总分为(97.0±17.5)分,心理韧性和睡眠质量总分中位数和第25、75百分位数[M(P_(25),P_(75))]分别为84.0(75.5,94.0)、6.0(5.0,9.0)分,精神科医生睡眠障碍检出率为33.9%(75/221)。精神科医生工作压力总分与心理韧性总分呈负相关[秩相关系数(r_(S))=-0.34,P<0.01],与睡眠质量总分呈正相关(r_(S)=0.48,P<0.01);心理韧性总分与睡眠质量总分呈负相关(r_(S)=-0.39,P<0.01)。精神科医生的工作压力对睡眠质量具有正向预测作用[标准化回归系数(β)=0.41,P<0.01],对心理韧性具有负向预测作用(β=-0.38,P<0.01);心理韧性对睡眠质量有负向预测作用(β=-0.24,P<0.01);心理韧性在工作压力与睡眠质量间起部分中介作用,中介效应占总效应的比例为22.0%。结论精神科医生工作压力、心理韧性均可直接影响其睡眠质量,其心理韧性在工作压力对睡眠质量的影响存在部分中介作用。

Objective To analyze the mediating effect of mental resilience on the relationship between work stress and sleep quality in psychiatrists.Methods A total of 221 front-line psychiatrists from four mental health centers in Shannxi Province were selected as the study subjects using convenience sampling method.The questionnaires of Scale for Occupational Stressors on Clinician,Chinese Version of Connor-Davidson Resilience Scale and Pittsburgh Sleep Quality Index Scale were used to investigate the work stress,mental resilience and sleep quality of the psychiatrists.We conducted Bootstrap mediation test to analyze the mediating effect of mental resilience using SPSS PROCESS V3.5 macro program.Results The total score of work stress of psychiatrists was 97.0±17.5,and the medium(P_(25),P_(75))of mental resilience and sleep quality scores were 84.0(75.5,94.0)and 6.0(5.0,9.0)respectively.The detection rate of sleep disorders among psychiatrists was 33.9%(75/221).The total score of work stress of psychiatrists was negatively correlated with the total score of mental resilience[rank correlation coefficient(r_(S))=-0.34,P<0.01],and was positively correlated with the total score of sleep quality(r_(S)=0.48,P<0.01).The total score of mental resilience was negatively correlated with that of sleep quality(r_(S)=-0.39,P<0.01).The work stress of psychiatrists had a positive predictive effect on sleep quality[standardized regression coefficient(β)=0.41.P<0.01],and a negative predictive effect on mental resilience(β)=-0.38,P<0.01).Mental resilience had a negative predictive effect on sleep quality(β)=-0.24,P<0.01.Mental resilience played a partial mediating role between work stress and sleep quality,and the mediating effect accounted for 22.0%of the total effect.Conclusion Both work stress and mental resilience of psychiatrists can directly affect their sleep quality,and the mental resilience has a partial mediating role in the effect of work stress on sleep quality.
