DTSQs量表在2型糖尿病患者中应用的信度、效度和反应度初步评价

目的 初步评价糖尿病治疗满意度问卷当前版(DTSQs)最表在中国2型糖尿病患者中应用的信度、效度和反应度.方法 以上海市3家医院和广州市4家医院门诊2型糖尿病病例为研究对象,采用中文版DTSQs问卷调查结合实验室检测的方法 收集资料,应用信度分析、因子分析结合结构方程模型、多元协方差分析分别评价DTSQs的信度、效度和反应度.结果 满意度维度分半信度系数为0.807,Cronbach α系数为0.717;探索性因子分析结果 显示,3个公因子累计方差贡献率为67.656%;拟合度检验结果 显示,相对χ2=4.95,DK=0.18;不同性别、不同血糖控制水平组患者DTSQs量表3个维度得分向量不同.研究数据支持DTSOs量表的理论假设,中文版DTSQs量表具有较高的信度和结构效度.结论 初步认为DTSQs量表中文版可以在中国2型糖尿病患者中应用.

Using satisfaction questionnaire status version (DTSQs) to study on the reliability, construct validity and responsiveness of diabetes treatment among Chinese diabetic outpatients

Objective Using 'diabetes treatment satisfaction questionnaire status version(DTSQs)'to evaluate the reliability, validity and responsiveness, among Chinese type 2 diabeties mellitus (T2DM) outpatients Methods A cross-sectional study was carried out in 749 T2DM outpatients from seven hospitals in Guangzhou and Shanghai, China. The DTSQs was self-administered by patients, under the help from interviewers for those having difficulties in reading. Split-half reliability correlation coefficient,Cronbaeh a and Spearman' were used to test the reliability. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed separately to examine the construct validity of the scale.The responsiveness of the scale was appraised by the multiple analysis of covarianee (MANCOVA). Results The split-half correlation coefficient was 0.807 and the Cronbaeh a was 0.717 of the six items on satisfaction of treatment. The three factors extracted by EFA explained 67. 656 % of the overall variance.Tberelative χ2 was 4.95 and DK was 0.18 in the goodness of test by CFA. The vector of treatment satisfaction, perceived hyperglycemia and hypoglycemia were different in males versus females and in poor versus good blood glucose controlled groups. The DTSQs showed good reliability and validity among T2D Moutpatients. Conclusion DTSQs was applicable to Chinese T2DM patients.
