【摘要】：目的探究睡眠质量对城市社区老年人抑郁的影响,考察觉知压力在二者关系间的中介作用。方法采用方便抽样法,于2015年5—7月对辽宁省沈阳市(和平区、铁西区和皇姑区)、大连市(沙河口区、甘井子区和西岗区)和锦州市(凌河区、古塔区和太和区)的社区老年人为调查对象,调查点设在公园、广场、社区服务中心等老年人经常活动的地方。分别采用一般人口学资料问卷、匹兹堡睡眠质量指数量表、觉知压力量表、流调中心抑郁量表调查其一般人口学资料、睡眠质量、觉知压力及抑郁情况。采用SPSS 21.0和AMOS 22.0软件对睡眠质量、觉知压力与抑郁三者之间关系进行Pearson相关分析和中介效应分析。结果共发放问卷1 050份,回收有效问卷1 032份,有效回收率为98.3%。睡眠质量得分为(5.5±2.9)分,觉知压力得分为(25.2±8.1)分,抑郁得分为(12.6±8.9)分。睡眠质量得分与觉知压力、抑郁得分均呈正相关(r=0.63、0.42,P0.01);觉知压力得分与抑郁得分呈正相关(r=0.36,P0.01)。简单线性回归分析结果显示,睡眠质量与抑郁有线性回归关系(β=0.460,SE=0.028,t=16.605,P0.001);睡眠质量与觉知压力有线性回归关系(β=0.627,SE=0.024,t=25.856,P0.001)。多元线性回归分析结果显示,睡眠质量、觉知压力与抑郁均有线性回归关系(睡眠质量:β=0.277,SE=0.034,t=8.053,P0.001;觉知压力:β=0.291,SE=0.034,t=8.471,P0.001)。中介效应验证结果显示,χ~2/df=4.713,规范拟合指数=0.926,相对拟合指数=0.907,增量拟合指数=0.941,非规范拟合指数=0.925,比较拟合指数=0.940,拟合优度指数=0.956,近似误差均方根=0.060。Bootstrap法检验结果显示,睡眠质量到抑郁直接效应、间接效应的95%CI均未包含0,综合说明觉知压力的部分中介效应模型成立,且部分中介效应为0.129,占总效应的62.6%(0.129/0.206)。结论睡眠质量主要通过觉知压力的中介作用对老年人抑郁产生间接效应,且觉知压力在睡眠质量与抑郁间起部分中介作用。
[Abstract]:Objective to investigate the effect of sleep quality on depression of the elderly in urban communities, and to investigate the mediating role of awareness stress in the relationship between the two. Methods from May to July, 2015, we selected Shenyang City (Heping District, Tiexi District and Huanggu District), Dalian City (Shahekou District, Ganjingzi District and Xigang District) and Jinzhou City (Linghe District) from May to July 2015. The elderly in the communities of Guta District and Taihe District were investigated, which were located in parks, squares, community service centers and other places where the elderly were often active. The general demographic data, sleep quality, perceived stress and depression were investigated by general demography questionnaire, Pittsburgh Sleep quality Index scale, Awareness stress scale and Center Depression scale. SPSS-21.0 and AMOS-22.0 software were used to analyze the relationship among sleep quality, perceived stress and depression by Pearson correlation analysis and mediating effect analysis. Results 1 050 questionnaires were sent out and 1 032 valid questionnaires were recovered. The effective recovery rate was 98.3%. The score of sleep quality was (5.5 卤2.9), the score of perceived stress was (25.2 卤8.1), and the score of depression was (12.6 卤8.9). The score of sleep quality was positively correlated with the scores of perceived stress and depression (r = 0.63, 0.42, P0.01), and the score of perceived stress was positively correlated with the score of depression (r = 0.36, P0.01). The results of simple linear regression analysis showed that there was a linear regression relationship between sleep quality and depression (尾 = 0.460, SE = 0.028, t = 16.605, P0.001). There was a linear regression between sleep quality and cognitive pressure (尾 = 0.627, SE = 0.024, t = 25.856, P 0.001). The results of multiple linear regression analysis showed that there was a linear regression between sleep quality, perceived stress and depression (sleep quality: 尾 = 0.277, SE0.034, t = 8.053, P0.001; perceived pressure: 尾 = 0.291, SE0.034, t = 8.471, P0.001). The results of multivariate linear regression analysis showed that there was a linear regression between sleep quality, perceived stress and depression (尾 = 0.277, SE0.034, t = 8.471, P0.001). The results of intermediate effect verification showed that 蠂 ~ 2 ~ 2dfx4.713, standard fitting index = 0.926, relative fitting index = 0.907, incremental fitting index = 0.941, non-standard fitting index = 0.925, and comparative fitting index = 0.940, the relative fitting index was 0.907, the increment fitting index was 0.941, and the non-standard fitting index was 0.925. The goodness-of-fit index = 0.956, the approximate error square root = 0.060.Bootstrap test results showed that the direct effect of sleep quality to depression, the indirect effect of 95%CI did not contain 0, indicating that part of the intermediary effect model of perceived stress was established. Part of the intermediate effect was 0.129, accounting for 62.6% (0.129 / 0.206) of the total effect. Conclusion Sleep quality has an indirect effect on depression in the elderly mainly through the mediating effect of awareness pressure, and awareness stress plays a partial role in the interplay between sleep quality and depression.
