重症肺炎病人心理韧性在睡眠质量与自我效能间的中介效应研究

Mediating effect of psychological resilience between sleep quality and self-efficacy in patients with severe pneumonia

目的:探讨重症肺炎(SP)病人心理韧性在睡眠质量与自我效能间的中介效应。方法:收集华中科技大学同济医学院附属同济医院2020年11月—2021年11月收治的SP病人资料,运用一般资料调查表、匹兹堡睡眠质量指数量表(PSQI)、一般自我效能感量表(GSES)、中国版心理韧性量表(CD-RISC)进行调查。分析各变量之间的相互关系,采用多元线性逐步回归分析中介效应。结果:本研究共发放122份问卷,回收有效问卷120份,120例SP病人PSQI总分为(13.60±1.71)分,44.17%病人存在失眠症状;GSES总分为(26.19±1.69),属于中水平;CD-RISC总分为(48.08±3.20)分;经Pearson相关性分析,SP病人PSQI总分与GSES总分、CD-RISC总分均呈负相关(r值分别为-0.645,-0.448,P<0.05);GSES总分与CD-RISC总分呈正相关(r=0.501,P<0.05);从中介效应模型可知,心理韧性在SP病人睡眠质量与自我效能间发挥部分中介效应。结论:心理韧性在SP病人睡眠质量与自我效能间发挥部分中介效应。

Objective:To explore the mediating effect of psychological resilience on sleep quality and self-efficacy in patients with severe pneumonia(SP).Methods:Patients with SP admitted to Tongji Hospital of Tongji Medical College of HUST from November 2020 to November 2021 were collected.The general information questionnaire,Pittsburgh Sleep Quality Index(PSQI),General Self-Efficacy Scale(GSES),and Chinese version of The Connor-Davidson Resilience Scale(CD-RISC)were used to investigate.The relationship between variables was analyzed,and the mediating effect was analyzed by multiple linear stepwise regression.Results:A total of 122 questionnaires were distributed in this study,and 120 valid questionnaires were recovered.The total PSQI score of 120 patients with SP was(13.60±1.71),and 44.17%of the patients had insomnia.The total score of GSES was(26.19±1.69),which belongs to the middle level.The total score of CD-RISC was(48.08±3.20).Pearson correlation analysis showed that the sleep quality(PSQI total score)score was negatively correlated with self-efficacy(GSES total score)score and psychological resilience(CD-RISC total score)score in patients with SP(r=-0.645,-0.448,P<0.05).There was a positive correlation between self-efficacy(GSES total score)and psychological resilience(CD-RISC total score)(r=0.501,P<0.05).According to the mediating effect model,mental toughness plays a partial mediating effect between sleep quality and self-efficacy in SP patients.Conclusions:Mental resilience partially mediated the relationship between sleep quality and self-efficacy in SP patients.
