To evaluate the correlation between the Voice Handicap Index (VHI) and objective voice measurements in patients with dysphonia of different origin.
Cross-sectional survey.
Otolaryngology department in a university hospital.
One hundred fifteen patients consulting for voice disorders were enrolled in the study: 32 presented with functional dysphonia (Group 1), 24 with unilateral vocal fold paralysis (Group 2), 30 with structural dysphonia (Group 3), and 29 with nodules (Group 4). From each patient, the maximum phonation time (MPT) and a voice spectrogram were obtained: patients with type 1 signal underwent perturbation analysis. Each patient completed the VHI.
No significant difference across the four groups, in the VHI scores and voice measurements, was found. The correlation between the different voice measurements was good, while those between the VHI domains were very good. Considering the patients with type 1 signal (n = 80) all together, the correlations between VHI and voice laboratory measurements ranged between poor and good. Analyzing each patient group separately, good correlations were found between MPT and functional and physical VHI domain in Group 1 (r = 0.58 and 0.68), jitter and functional VHI domain in Group 2 (r = 0.61), MPT and functional VHI domain in Group 3 (r = 0.52), and physical VHI domain and jitter, shimmer, and noise-to-harmonic ratio in Group 4 (r = 0.58, 0.77, 0.76).
The VHI and the voice laboratory measurements give independent information. However, the correlation between VHI and some laboratory measurements increases in populations with voice disorder of the same origin.
评估不同病因性发声障碍患者的嗓音障碍指数（VHI）与客观嗓音测量值之间的相关性。
横断面调查。
大学医院耳鼻喉科。
共纳入 115 例因嗓音障碍就诊的患者：32 例为功能性发声障碍（第 1 组），24 例为单侧声带麻痹（第 2 组），30 例为结构性发声障碍（第 3 组），29 例为声带小结（第 4 组）。从每位患者中获得最长发声时间（MPT）和嗓音频谱图：具有 1 型信号的患者进行声扰分析。每位患者均完成 VHI 量表评估。
四组患者的 VHI 量表评分和嗓音测量值均无显著差异。不同嗓音测量值之间的相关性较好，而 VHI 各领域之间的相关性则非常好。考虑到所有具有 1 型信号的患者（n = 80），VHI 与嗓音实验室测量值之间的相关性范围为差至好。分别分析各患者组，发现第 1 组中 MPT 与功能和生理 VHI 领域之间、第 2 组中声扰与功能 VHI 领域之间、第 3 组中 MPT 与功能 VHI 领域之间、第 4 组中生理 VHI 领域与声扰、颤动和噪声与谐噪比之间存在良好相关性（r = 0.58 和 0.68、r = 0.61、r = 0.52、r = 0.58、0.77、0.76）。
VHI 和嗓音实验室测量值提供了独立的信息。然而，在具有相同来源的嗓音障碍患者群体中，VHI 与某些实验室测量值之间的相关性增加。
