Abstract

Abstract: 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.

摘要： 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。
