OBJECTIVES/HYPOTHESIS: Recent developments in voice assessment propose the use of quality of life measurements. The Voice Handicap Index (VHI) is one of the most psychometrically robust and well-studied instruments among the various instruments for measuring quality of life. Two versions of VHI (VHI-30 and VHI-10) have been shown to be valid instruments for distinguishing dysphonic from nondysphonic individuals and also for documenting treatment effect for dysphonic patients. The VHI has been used worldwide; however, the psychometric properties of the Chinese version of VHI remains untested. This study aimed to investigate such properties of the Chinese VHI-30 and VHI-10 in the Hong Kong Chinese population.
Psychometric analysis of the Chinese VHI-30 and VHI-10 in dysphonic patients and control subjects.
The original VHI-30 was translated into Chinese and was completed by 131 dysphonic patients and 54 nondysphonic individuals. The dysphonic patients also self-rated their dysphonic severity.
Results showed high test-retest reliability and high item-total correlation for both Chinese VHI-30 and VHI-10. Both Chinese versions could be used to distinguish different dysphonic groups and between dysphonic and nondysphonic groups. Significant correlation was found between the VHI scores and the patients' self-rated dysphonic severity.
The present study supported the original three-factorial structures of the VHI-30 and the use of the VHI for the Chinese population. It is shown that the Chinese VHI-10 is a strong representation of VHI-30 and is recommended for use in clinics because of its validity and ease of use by patients.
目的/假设：语音评估的最新进展建议使用生活质量测量方法。嗓音障碍指数（VHI）是各种生活质量测量工具中，在心理测量方面最稳健且研究充分的工具之一。已证明VHI的两个版本（VHI - 30和VHI - 10）是区分发声障碍者与非发声障碍者的有效工具，也可用于记录发声障碍患者的治疗效果。VHI已在全球范围内使用；然而，中文版VHI的心理测量特性尚未经过测试。本研究旨在调查中文版VHI - 30和VHI - 10在香港华人中的此类特性。
对发声障碍患者和对照受试者的中文版VHI - 30和VHI - 10进行心理测量分析。
将原始的VHI - 30翻译成中文，由131名发声障碍患者和54名非发声障碍个体完成。发声障碍患者还对自己的发声障碍严重程度进行了自评。
结果显示，中文版VHI - 30和VHI - 10均具有较高的重测信度和项目 - 总分相关性。两个中文版均可用于区分不同的发声障碍组以及发声障碍组与非发声障碍组。发现VHI评分与患者自评的发声障碍严重程度之间存在显著相关性。
本研究支持VHI - 30原有的三因素结构以及VHI在华人中的应用。结果表明，中文版VHI - 10是VHI - 30的有力代表，因其有效性和患者使用的便利性，推荐在临床中使用。
