糖尿病患者生命质量量表研制及评价

目的对慢性病患者生命质量量表系列-糖尿病量表(QLICD-DM)测试版进行评价。方法收集2型糖尿病住院患者159例,采用自主研制的QLICD-DM测试版,于患者入院时、入院第2天和出院时进行量表测评,对量表的信度、效度、反应度进行评价。结果量表各维度的内部一致性α系数和分半系数均在0.7以上,重测信度相关系数均高于0.9;量表各条目与所属维度或维度的相关均大于该条目与其他维度或维度的相关;探索性因子分析结果显示,第1主成分主要涵盖心理状况各条目,方差贡献率达到33.919%;其次为第2主成分的糖尿病并发症条目,方差贡献率为12.006%;治疗前后患者的躯体功能、心理功能、社会功能、特异模块评分及量表总评分差异均有统计学意义(P<0.01),标准反应均数(SRM)分别为0.691、0.638、0.428、1.148、1.223。结论所研制的慢性病患者糖尿病生命质量量表具有较好信度、效度和反应度,可作为国内糖尿病患者生命质量测评工具。

Evaluation on quality of life instrument for patients with diabetes mellitus

Objective To evaluate a self-designed quality of life instrument(test version) for chronic diseases-diabetes mellitus(QLICD-DM). Methods The quality of life among 159 type II diabetes mellitus inpatients was measured with QLICD-DM at three times:on the first and second day of the hospitalization,and on the day of discharge form the hospital.The validity,reliability and responsiveness of the QLICD-DM were evaluated. Results The Cronbach’s alpha and split-half reliability in all domains was greater than 0.7.Test-retest reliability in all domains was greater than 0.9.All of the correlation coefficient between each item and its facet or domain were greater than the correlation coefficient with other facets or domains.Exploratory factor analyses showed that the first principal component representing the aspects of psychological functioning explained 33.919% of the variance and the second principal component representing the aspects of the diabetic complication explained 12.006% of the variance.The differences before and after the treatment in all domains including physical functioning,psychological functioning,social functioning,special module domain,and total score of the instrument had statistical significance(P<0.01) with the standardized responsive mean(SRM) of 0.691,0.638,0.428,1.148,and 1.223. Conclusion The QLICD-DM is good in reliability,validity,and responsiveness and suitable to serve as a quality of life measurement instrument for patients with diabetes mellitus in China.
