睡眠质量与感知压力在护理学专业大学生正念主体性与生活满意度关系中的链式中介作用

Chain mediating effect of sleep quality and perceived stress on relationship between mindful subjectivity and life satisfaction of nursing college students

目的分析合肥市某高校护理学专业大学生正念主体性、睡眠质量、感知压力及生活满意度的相关性,为今后护理学大学生保持良好的身心健康提供策略支持。方法2021年10—11月,采用便利抽样法选取合肥市某高校护理学专业各年级大学生为研究对象,应用《正念主体性问卷》《压力感知问卷》《匹茨堡睡眠质量问卷》及《生活满意度问卷》调查护理学专业大学生不同人口学特征、正念主体水平、睡眠质量、感知压力及生活满意度现况,并对数据进行分析。结果共纳入研究对象628名,其中男生62人(9.87%),女生为566人(90.13%)。正念主体性得分为(53.40±9.90)分,中文版压力感知量表总分为(42.68±8.45)分,匹茨堡睡眠质量指数问卷总分为(7.19±3.16)分,生活满意度得分为(9.19±2.30)分。相关分析显示,正念主体性与睡眠质量和生活满意度均呈正相关,与感知压力呈负相关(均P<0.01);感知压力与正念主体性、睡眠质量及生活满意度均呈负相关(均P<0.01)。正念主体性对生活满意度的总体效应为0.215(P<0.01),正念主体性可以正向预测睡眠质量(β=0.224,P<0.01),负向预测感知压力(β=-0.307,P<0.01)。感知压力和睡眠质量对护理学专业实习生正念主体性与生活满意度间关系的中介效应显著,中介总效应值为0.258。主要存在3条中介效应链:中介效应路径1由正念主体性-压力-生活满意度组成0.033,中介效应路径2由正念主体性-睡眠-生活满意度组成0.066,中介效应路径3由正念主体性-压力-睡眠-生活满意度组成0.056,3条中介效应链占总中介效应的百分比分别为11.56%、25.83%和21.61%。结论正念主体性可以直接预测生活满意度,也可以通过睡眠质量、感知压力的中介作用及睡眠质量、感知压力的链式中介作用预测生活满意度。

Objective To analyze the correlation of mindfulness subjectivity,sleep quality,perceived stress and life satisfaction among nursing students in a university in Hefei City,provide strategic support for future nursing college students to maintain good physical and mental health.Methods From October to November of 2021,the convenience sampling method was used to select students of all grades majoring in nursing in a university in Hefei City as the research objects.The present situation of different demographic characteristics,mindfulness subject level,sleep quality,perceived stress and life satisfaction of college students majoring in nursing were investigated by using Mindfulness subjectivity questionnaire,Stress perception questionnaire,Pittsburgh sleep quality questionnaire and Life satisfaction questionnaire.Results A total of 628 subjects were included in this study,including 62(9.87%)male students and 566(90.13%)female students.The score of mindfulness subjectivity was(53.40±9.90)points,the score of Chinese version of pressure perception scale was(42.68±8.45)points,the score of Pittsburgh sleep quality index questionnaire was(7.19±3.16)points,and the score of life satisfaction was(9.19±2.30)points.The correlation analysis showed that mindfulness subjectivity was positively correlated with sleep quality and life satisfaction,and negatively correlated with perceived stress(all P<0.01).The perceived stress was negatively correlated with mindful subjectivity,sleep quality and life satisfaction(all P<0.01).The overall effect of mindfulness subjectivity on life satisfaction was 0.215(P<0.01),the mindfulness subjectivity positively predicted sleep quality(β=0.224,P<0.01),and negatively predicted perceived stress(β=-0.307,P<0.01).The mediating effect of perceived stress and sleep quality on the relationship between mindfulness subjectivity and life satisfaction of nursing interns was significant,with a total mediating effect value of 0.258.There were three main mediation chain implementations:mediating effect path 1 was composed of mindfulness subjectivity-stress-life satisfaction 0.033,mediating effect path 2 was composed of mindfulness subjectivity-sleep-life satisfaction 0.066,mediating effect path 3 was composed of mindfulness subjectivity-stress-life satisfaction 0.056,and three mediating effect chains accounted for 11.56%,25.83%and 21.61%of the total mediating effect,respectively.Conclusion The mindfulness subjectivity can directly predict life satisfaction,and it can also predict life satisfaction through the mediating effect of sleep quality and perceived stress and the chain mediating effect of sleep quality and perceived stress.
