To investigate the characteristics and clinical application of Mandarin Chinese version of the Voice Handicap Index (VHI).
A cross-culture adaptation was used to develop the Mandarin Chinese version of the VHI. The translated version was then administered to 1766 dysphonic patients and 120 control subjects; 210 of the patients were treated with phonosurgery or BOTOX injection. Disorders were chronic laryngitis, benign vocal fold disorders, pathologic sulcus vocalis, benign or malignant tumors of vocal fold, spasmodic dysphonia (SD) and unilateral vocal fold paralysis (UVFP), and functional dysphonia.
The Cronbach's α score for the overall VHI was 0.956; the functional, physical, and emotional subscales had values of 0.922, 0.872, and 0.933, respectively. The test-retest reliability coefficient was 0.991 (P<0.01). Correlations between the subscales and the overall VHI as well as among the subscales were all significant (P<0.01) Principal-component analysis revealed six-factor eigenvalues exceeding 1, explaining 75.39% of the total variance. The total VHI scores and subscale scores were statistically higher for dysphonic groups (P<0.001). The order of disease classification from highest score to lowest score was: SD, functional dysphonia, UVFP, sulcus vocalis, benign and malignant tumor, benign vocal fold disorders, and chronic laryngitis. The emotional scores were the highest in SD, and followed by functional dysphonia; the physical scores were the highest in the other groups. Treatment leads to statistically improvement in VHI scores (P<0.05).
The Mandarin Chinese version of VHI appears to be a reliable and valid tool in assessing dysphonia in Mandarin Chinese speakers.
研究汉语嗓音障碍指数（VHI）中文版的特点和临床应用。
采用跨文化适应法制定汉语嗓音障碍指数（VHI）中文版。对 1766 例嗓音障碍患者和 120 例对照组进行了翻译版本的评估；其中 210 例患者接受了语音手术或肉毒毒素注射治疗。疾病包括慢性喉炎、良性声带疾病、病理性沟状声带、声带良恶性肿瘤、痉挛性发声障碍（SD）和单侧声带麻痹（UVFP）以及功能性发声障碍。
VHI 总分的 Cronbach's α 评分为 0.956；功能、生理和情感分量表的评分为 0.922、0.872 和 0.933。测试-重测信度系数为 0.991（P<0.01）。分量表与总分以及分量表之间的相关性均具有统计学意义（P<0.01）。主成分分析显示，六个特征值大于 1，解释了总方差的 75.39%。嗓音障碍组的总 VHI 评分和分量表评分均显著高于对照组（P<0.001）。疾病分类的总分从高到低的顺序为：SD、功能性发声障碍、UVFP、沟状声带、声带良恶性肿瘤、良性声带疾病和慢性喉炎。SD 组的情感评分最高，其次是功能性发声障碍组；其他组的生理评分最高。治疗后 VHI 评分有统计学意义的改善（P<0.05）。
汉语嗓音障碍指数（VHI）中文版似乎是一种可靠有效的评估汉语发声障碍的工具。
