匹兹堡睡眠质量指数在肠易激综合征患者中的应用评价

背景：肠易激综合征（IBS）患者常伴明显的睡眠障碍，但目前临床上尚缺乏专用于IBS患者的睡眠质量评价量表。目的：分析匹兹堡睡眠质量指数（PSOI）评价IBS患者睡眠质量的信度、效度和反应度。方法：纳入符合罗马Ⅲ标准的成人IBS患者201例，受试者自行完成PSQI。随机抽取42例患者于2周后重测。结果：IBS患者的总失眠率为25．9％，PSQL总均分为5．83±2．89．重测信度K值为0．810，分半信度系数为0．787，总体Cronbach’s α系数为0．789。效度分析示主成分累计方差贡献率为67．5％。项目分析法示PSQI具有鉴别出不同受试者的反应度。结论：PSQI具有良好的信度、效度和反应度．可用于IBS患者睡眠质量的综合评价．

Evaluation of Pittsburgh Sleep Quality Index in Assessing Patients with Irritable Bowel Syndrome

Background:Prominent sleep disorder is commonly seen in patients with irritable bowel syndrome(IBS),but there is a lack of specialized scale for sleep quality evaluation in clinical practice.Aims:To analyze the reliability,validity and responsibility of Pittsburgh Sleep Quality Index(PSQI) for assessing sleep quality in IBS patients.Methods:Two hundred and one adult IBS patients diagnosed in accordance with Rome Ⅲ criteria were enrolled in this study.All the subjects were requested to fill out the PSQI by themselves.Forty-two randomly selected subjects were retested after 2 weeks.Results:The overall insomnia rate in IBS patients was 25.9%.The mean score of total PSQI was 5.83±2.89.The κ value,split-half coefficient and overall Cronbach’s α coefficient were 0.810,0.787 and 0.789,respectively.Cumulative variance of principal components was 67.5% by validity analysis,and item analysis showed that PSQI could distinguish different subjects.Conclusions:PSQI has high reliability,validity and responsibility,and can be used for the assessment of sleep quality in IBS patients.
