嗓音障碍指数量表中文版信度和效度评价

目的 探讨自行翻译的中文版嗓音障碍指数(voice handicap index,VHI)量表信度和效度特征.方法 采用健康相关生活质量评价跨文化翻译法对VHI量表进行系统翻译.546例嗓音障碍患者及80例健康对照者共626例完成了中文版量表评估,其中30例患者及20例健康对照者还同时应用香港中文版量表进行评估.结果 VHI量表中文版总量表和3个分量表内部的一致性为0.8657～0.9517;重测信度为r=0.992(P＜0.001);总量表、分量表及3个分量表各自内部的r值为0.643～0.904(P＜0.01);与香港中文版比较,两者之间差异无统计学意义(Z=0.397,P=0.691),并且有很强的相关性(r=0.995,P＜0.001);因素分析特征根大于1的公因子6个,累计贡献率77.24%,各条目负荷大于0.4;不同嗓音疾病患者总量表及功能、生理、情感3个分量表评分均明显高于对照组,差异有统计学意义(Z值分别为17.69、14.14、17.68和15.50,P值均为0.000).结论 VHI量表中文版有很好的信度和效度,可以作为发音障碍自我评估工具应用.

Analysis of reliability And validity of the Chinese version of voice handicap index (VHI)

Objective To investigate the reliability and validity of the Chinese version of voice handicap index (VHI).Methods The cross-cultural adaptation of health-related quality of life (HRQOL) measures was used to evaluate the Chinese version of VHI.Five hundred forty six dysphonic patients and 80 control subjects were included,30 of patients and 20 of control subjects also had Hong Kong version VHI test simultaneously.Results The intemal consistency reliability of overall VHI scores and three subscale scores of the Chinese version of VHI were 0.8657-0.9517.The reliability coefficients (test to retest,2-week interval) was 0.992(P＜0.001).The correlation coefficiency of overall VHI scores and three subseale scores and internal subscale scores were 0.643-0.904(P＜0.01).There were no significant difference between the Chiness version and Hong Kong Chinese version (Z=0.397,P=0.691) with high dependability(r=0.995,P＜0.001).The factor analysis of construct validity shows that the eigenvalue of 6 factors is above 1.The cumulative proportion was 77.24%.The loading was higher than 0.4 among every item.VHI total scores were significantly higher in dysphonic patients than in control subjects(Z=17.69,P=0.000).,This is also true for all VHI subscores in the functional(Z=14.14.P=0.000),physical(Z=17.68,P=0.000) and emotional domains(Z=15.50,P=0.000).Condusions The Chinese version of VHI had a good reliability and validity.It can be used to evaluate dysphonic patients.
