Factors underlying voice disorders can be categorized into three distinct domains: emotional, physical, and functional. The Voice Handicap Index (VHI) subjectively evaluates voice disorders in terms of these three factors. On the other hand, Voice Laboratory Measurements (VLM) use objective criteria to evaluate the severity of voice disorders. Use of these two different tests (VHI and VLM) on dysphonic patients has, however, tended to yield results that vary widely in their conclusions. This report reviewed 135 testing sessions on dysphonia patients. Seventy-nine of the tests were VHI, and 56 were VLM. All VHI and VLM parameters were entered into a statistical program and analyzed using a Pearson correlation. The results show that each VHI parameter provides a significant level of reliability (P < 0.01) when compared with other VHI parameters. Four VLM parameters also demonstrated significant reliability (P < 0.01) in comparison with other VLM parameters. However, when comparing across testing methods, VHI and VLM parameter reliability is shown to be poor (P > 0.05). With such a large discrepancy between the results of VHI and VLM testing, no objective parameter can yet be regarded as a definitive prognostic factor in a subjective evaluation of dysphonic patients.
情感、身体和功能。嗓音障碍指数（VHI）根据这三个因素对嗓音障碍进行主观评估。另一方面，嗓音实验室测量（VLM）使用客观标准来评估嗓音障碍的严重程度。然而，对嗓音障碍患者使用这两种不同的测试（VHI和VLM）往往会得出结论差异很大的结果。本报告回顾了135例嗓音障碍患者的测试情况。其中79项测试为VHI，56项为VLM。所有VHI和VLM参数都输入到一个统计程序中，并使用Pearson相关性进行分析。结果表明，与其他VHI参数相比，每个VHI参数都具有显著的可靠性水平（P < 0.01）。与其他VLM参数相比，四个VLM参数也显示出显著的可靠性（P < 0.01）。然而，在比较不同测试方法时，VHI和VLM参数的可靠性较差（P > 0.05）。由于VHI和VLM测试结果存在如此大的差异，在对嗓音障碍患者进行主观评估时，尚无客观参数可被视为明确的预后因素。
