患者赋权量表在慢性病患者中应用的信效度研究

摘要

Objective To evaluate reliability and validity of the application of Client Empowerment Scale( CES, Chinese version)in patients with chronic disease. Methods The CES of English version was translated and back - translated and finally a Chinese version of CES was formed after culture adaptation. From July to September in 2015,300 hospitalized patients with chronic diseases in Nanfang Hospital,Southern Medical University were selected to conduct a questionnaire survey,the investigated contents included patients' general conditions and CES,and the effective response rate was 100. 0% . After one week,20 patients were randomly selected to retest,and the effective response rate was also 100. 0%. According to CES scores of two surveys,the reliability and validity of the scale was tested,including content consistency,test - retest reliability,content validity and construct validity. Results The Cronbach's α coefficient of the total scale was 0. 956,and the Cronbach's α of each dimension ranged from 0. 698 to 0. 900. Test - retest reliability of the total scale was 0. 991 and the reliability of each dimension was 0. 775 ~ 0. 985. Content validity index( CVI)of each dimension in the scale was 0. 821 ~ 0. 949 with an average CVI of 0. 870. Spearman rank correlation showed that among the scores of each dimension were positively correlated(rs value of 0. 412 ~0. 877,P < 0. 05),the scores of the total scale were positively correlated with the scores of each dimension(rs value of 0. 652 ~0. 943,P < 0. 05). Eight common factors were extracted by principal component analysis,and accumulative contribution rate was 59. 74%. Conclusion CES of Chinese version is of good reliability and validity,and can be used for evaluating the empowerment level of patients with chronic disease.%目的：评价中文版患者赋权量表（CES）在慢性病患者中应用的信效度。方法对英文版 CES 进行翻译和回译，文化调试后形成中文版 CES。于2015年7—9月，选取在南方医科大学南方医院接受住院治疗的慢性病患者300例进行问卷调查，内容包括患者的一般情况和 CES，问卷有效回收率为100.0%。1周后，随机抽取20例患者进行重测，问卷有效回收率亦为100.0%。根据两次调查的 CES 得分对量表进行信效度检验，包括内容一致性、重测信度、内容效度及结构效度。结果总量表的 Cronbach's α系数为0.956，各维度 Cronbach's α系数为0.698~0.900。总量表的重测信度为0.991，各维度重测信度为0.775~0.985。量表各维度内容效度指数（CVI）为0.821~0.949，平均CVI 为0.870。Spearman 秩相关结果显示，各维度得分间均呈正相关（rs 值为0.412~0.877，P <0.05），总量表得分与各维度得分间均呈正相关（rs 值为0.652~0.943，P <0.05）。经主成分因子分析共提取出8个公因子，累计贡献率为59.74%。结论中文版 CES 的信效度良好，可用于评估慢性病患者的赋权水平。
