导论.语音障碍指数（VHI）被认为是一种有用的主观评估方法的发音障碍。最初的VHI已被翻译成许多其他语言，包括日语（J-VHI）。虽然J-VHI的信度和效度已经建立，但截止点尚未确定。本研究的目的是探讨J-VHI与其他嗓音实验室测量值之间的关系，并确定分界点。这项研究包括167名发声障碍患者和55名健康志愿者。所有患者和志愿者在首次访视时完成J-VHI，并确定以下结果：发声障碍患者和健康志愿者的VHI评分，根据疾病的VHI评分，截止点，以及VHI评分与其他语音实验室测量值之间的相关性。与健康志愿者组相比，发声障碍组的总VHI（VHI-T）和个体领域（功能领域[VHI-F]、情感领域[VHI-E]、身体领域[VHI-P]）评分均显著较高。良性粘膜病变亚组的VHI-T、VHI-F和VHI-E评分显著低于其他疾病亚组。等级-粗糙-呼吸-无力-紧张量表的G量表和B量表显示与VHI-T、VHI-F和VHI-P评分显著相关。同样，A量表显示与VHI-T、VHI-F和VHI-E评分显著相关。从受试者工作特征曲线中选择VHI-T的截止点（12），以最大限度地提高灵敏度和特异性。同样，还获得了VHI-F（5）、VHI-P（5）和VHI-E（3）的临界点。VHI-T阴性（VHI 13）组的最大发声时间、音高范围、G量表和B量表存在显著性差异。这些研究结果表明，使用VHI的自我评估可以作为一个独立的评估和筛查工具，为患者发声障碍。
Introduction. The Voice Handicap Index (VHI) is recognized as a useful subjective assessment method for dysphonia. The original VHI has been translated into numerous other languages, including Japanese (J-VHI). Although the reliability and validity of the J-VHI have already been established, the cutoff point has not been determined. The aims of this study were to investigate the relationship between the J-VHI and other voice laboratory measurements, and determine the cutoff point.Method. This study included 167 dysphonic patients and 55 healthy volunteers. All patients and volunteers completed the J-VHI at the initial visit, and the following outcomes were determined: VHI scores of patients with dysphonia and healthy volunteers, VHI scores according to disease, cutoff point, and correlations between VHI scores and other voice laboratory measurements.Results. Both the total VHI (VHI-T) and individual domain (functional domain [VHI-F], emotional domain [VHI-E], physical domain [VHI-P]) scores were significantly higher in the dysphonia group compared to the healthy volunteer group. VHI-T, VHI-F, and VHI-E scores were significantly lower in the benign mucosal lesion subgroup, compared to the other disease subgroups. The G scale and B scale of the grade-roughness-breathiness-asthenia-strain scale showed a significant association with VHI-T, VHI-F, and VHI-P scores. Similarly, the A scale showed a significant association with VHI-T, VHI-F, and VHI-E scores. The cutoff point (12) for VHI-T was chosen from the receiver operating characteristic curve to maximize sensitivity and specificity. Similarly, the cutoff points for VHI-F (5), VHI-P (5), and VHI-E (3) were also obtained. Significant differences in maximum phonation time, pitch range, G scale, and B scale were observed between the VHI-T negative (VHI 13) groups.Conclusion. These findings suggest that self-evaluation using the VHI could serve as an independent assessment and screening tool for patients with dysphonia.
