痛风患者治疗依从性量表的编制及信效度检验

Development and validation of the Gout Treatment Adherence Scale

目的研制痛风患者治疗依从性量表并检验其信效度,为痛风患者治疗依从性评估提供可靠工具。方法采用文献回顾和专家咨询法形成痛风患者治疗依从性初量表,选取三甲医院门诊就诊的痛风患者193例进行问卷调查,运用项目分析、探索性因子分析等方法检验初量表的信效度并形成终量表。结果形成的量表包括服药依从性、饮食依从性、运动保暖依从性及戒烟限酒依从性4个维度共14个条目,量表Cronbach′sα系数为0.863,重测信度为0.820,量表水平的内容效度指数为0.944,累积方差贡献率为70.390%。结论痛风患者治疗依从性量表具有良好的信效度,可作为痛风患者治疗依从性测量工具。

Objective To develop the Gout Treatment Adherence Scale and test its reliability and validity,so as to provide a reliable tool assessing treatment adherence for gout patients.Methods The preliminary Gout Treatment Adherence Scale was formed through literature review and expert consultation,then it was used to investigate 193 gout outpatients from a 3A hospital,and the item analysis and exploratory factor analysis were conducted to examine its reliability and validity and eventually formed the final scale.Results The final scale consisted of 4 dimensions(medication adherence,diet adherence,exercise and warm-keeping adhe-rence,and smoking cessation and alcohol restriction adherence)and 14 items,its Cronbach′sαcoefficient was 0.863,test-retest reliability was 0.820,the content validity index of the scale was 0.944,and the four factors of the scale explained 70.390%of the total variance.Conclusion The Gout Treatment Adherence Scale has good reliability and validity,so it can be used to assess treatment adherence for gout patients.
