摘要
目的:编制甲基丙二酸血症(MMA)患儿饮食治疗依从性评估量表,并检验其信效度。方法:基于成熟的计划行为理论(TPB),通过文献检索、质性访谈、专家函询及研究小组讨论构建初始版MMA患儿饮食治疗依从性评估量表。于2022年6月—2022年7月在全国罕见病病友组织(MMA和丙酸血症之家)便利选取218名MMA患儿照顾者进行调查,对量表进行项目分析和信效度检验。结果:MMA患儿饮食治疗依从性评估量表包括饮食行为意向、饮食治疗行为、饮食行为态度、主观规范和饮食知觉行为控制5个维度,共17个条目。2轮函询问卷回收率、有效率均为100%,专家权威程度系数分别为0.896和0.882。探索性因子分析提取5个公因子,累计方差贡献率为70.179%。验证性因子分析结果显示,卡方自由度比为1.176,近似误差均方根为0.040,比较拟合指数为0.979,增量拟合指数为0.980,Tucker⁃Lewis指数为0.974,各因子的平均方差萃取量均>0.5,组合信度均>0.7,各因子间相关系数为0.099~0.257,均小于对应平均方差萃取量的平方根,量表水平内容效度指数为0.988,条目水平内容效度指数为0.833~1.000,量表总体的Cronbach'sα系数为0.874,分半信度为0.803。结论:MMA患儿饮食治疗依从性评估量表具有良好的信效度,可用于评估MMA患儿的饮食治疗依从性。
Objective:To develop test of diet treatment compliance evaluation scale for children with methylmalonic acidemia(MMA)and to test its reliability and validity.Methods:The initial version of diet treatment compliance evaluation scale for children with MMA was constructed through literature retrieval,qualitative interviews,expert correspondence and research group discussion based on the mature theory of planned behavior.218 caregivers of children with MMA were selected for investigation at the convenience in the National Association of Patients with Rare Diseases(Home of MMA and propionic acidemia)to analysis Item and to test reliability and validity of the scale from June,2022 to July,2022.Results:The diet treatment compliance evaluation scale for children with MMA included five dimensions(dietary behavior intention,dietary treatment behavior,dietary behavior attitude,subjective norms and dietary perception behavior control)with a total of 17 items.The recovery rate and effectiveness rate of the two rounds of correspondence questionnaires all were 100%.The authority coefficient of experts were 0.896 and 0.882,respectively.Five common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 70.179%.The confirmatory factor analysis results showed that the chi⁃square degree of freedom ratio was 1.176,the root mean square residual was 0.040,the comparative goodness of fit index was 0.979,the incremental fit index was 0.980,the Tucker⁃Lewis index was 0.974.The average variance extraction amount of each factor was>0.5.The combined reliability of each factor was>0.7.The correlation coefficient among each factor were from 0.099 to 0.257,which was less than the square root of the corresponding average variance extraction amount.The scale⁃level average content validity index was 0.988,the item⁃level content validity index ranged from 0.833 to 1.000.The coefficient of Cronbach'sαwas 0.874,and the split⁃half reliability was 0.803.Conclusions:The diet treatment complianc
