肺康复自我效能适应指数的汉化及信效度检验

Chineseization and reliability and validity test of Pulmonary Rehabilitation Adapted Index of Self⁃Efficacy

目的:汉化肺康复自我效能适应指数(PRAISE),并检验其在慢性阻塞性肺疾病(COPD)病人中的信效度。方法:采用Brislin翻译模式翻译,通过专家咨询和预调查对量表进行调适,采用便利抽样法对326例COPD病人进行调查,评价量表信效度。结果:中文版PRAISE条目水平的内容效度指数(I-CVI)为0.86~1.00,平均量表水平的内容效度指数(S-CVI/Ave)为0.96,探索性因子分析共提取3个公因子,累计方差贡献率为59.725%。修正模型的卡方自由度比(χ2/ν)为1.463,模拟拟合指数(NFI)为0.926,拟合优度指数(GFI)为0.941,递增拟合指数(IFI)为0.975,比较拟合优度指数(CFI)为0.975,近似误差均方根(RMSEA)为0.046。中文版PRAISE总体的Cronbach'sα系数为0.896。最终形成的中文版PRAISE包含13个条目。结论:中文版PRAISE在中国文化背景下具有良好的信度和效度,可作为COPD病人肺康复自我效能的评估工具。

Objective:To translate Pulmonary Rehabilitation Adapted Index of Self-Efficacy(PRAISE)into Chinese and to test its reliability and validity in chronic obstructive pulmonary disease(COPD)patients.Methods:The scale was translated according to the Brislin translation model.The scale was adjusted by expert consultation and pre-investigation.A total of 326 COPD patients were selected for investigation by convenient sampling method in order to test its reliability and validity.Results:The item-level content validity index(I-CVI)of the Chinese version of PRAISE were from 0.86 to 1.00,and the average scale-content validity index(S-CVI/Ave)was 0.96.Exploratory factor analysis extracted three common factors,and the cumulative variance contribution rate was 59.725%.The Chi-square degree of freedom ratio(χ2/ν)of the modified model was 1.463,the normal of fit index(NFI)was 0.926,the Goodness of Fit Index(GFI)was 0.941,the incremental fit index(IFI)was 0.975,the comparative fit index(CFI)was 0.975,and the root mean square error of approximation(RMSEA)was 0.046,the Cronbach'sαcoefficient of Chinese version of PRAISE was 0.896.The final Chinese version of PRAISE contained 13 indicators.Conclusions:The Chinese version of PRAISE has good reliability and validity in China,and can be used as a tool to evaluate self-efficacy of COPD patients in pulmonary rehabilitation.
