Outcome measures describing acoustic voice quality and self-perceived vocal handicap are commonly used in clinical voice practice. Previous reports of the relationship between acoustic and self-perceived measures have found only limited associations, but it is unclear if acoustic measures associated with voice quality and self-perceived voice handicap change in a similar manner over the course of voice treatment. The current study, therefore, considered the relationship between the degree of change in Acoustic Voice Quality Index (AVQI) and Voice Handicap Index (VHI-30 and VHI-10) in dysphonic patients receiving treatment in a private practice voice clinic.
Data were collected retrospectively from patient records of a private practice voice clinic over 80 consecutive months. For each patient, their voice disorder diagnosis, age, and biological sex were collected as well as pre-and post-treatment measures of the AVQI and VHI-30 or VHI-10 depending on which version was used. Correlations were calculated between the AVQI and VHI-30 and the AVQI and VHI-10 before and after treatment as well as for the percentage change of AVQI and VHI-30/VHI-10. Friedman and Kruskal-Wallis tests were used to determine the pre-and post-treatment effect and group differences respectively.
Seventy-eight patients were included in the analyses. The scores of the AVQI (χ²[1] = 24.01, P < 0.001), VHI-30 (χ²[1] = 18.00, P < 0.001), and VHI-10 (χ²[1] = 38.35, P < 0.001) all improved significantly after treatment. However, correlations between the AVQI and VHI-30, and the AVQI and VHI-10 were all non-significant, except for a moderate correlation between the AVQI and VHI-10 before treatment (r[43] = 0.31, P = 0.04). The percentage change of the AVQI and the VHI-30/VHI-10 did not correlate significantly.
Voice therapy significantly improved acoustic and self-perceived vocal outcome measures. However, there was no significant relationship between these measures before or after treatment, nor was there a relationship in their degree of change. Results support the notion that VHI and AVQI measure unique constructs and that voice therapy can have a positive impact on both.
描述声学语音质量和自我感知嗓音障碍的结果测量在临床语音实践中经常使用。先前关于声学和自我感知测量之间关系的报告发现只有有限的关联，但尚不清楚在语音治疗过程中，与语音质量和自我感知嗓音障碍相关的声学测量是否以相似的方式发生变化。因此，本研究考虑了在私人诊所接受治疗的嗓音障碍患者的声学语音质量指数（AVQI）和嗓音障碍指数（VHI-30 和 VHI-10）的变化程度之间的关系。
从 80 多个连续月的私人诊所患者记录中回顾性收集数据。为每位患者收集了他们的语音障碍诊断、年龄和生物学性别，以及 AVQI 和 VHI-30 或 VHI-10 的治疗前后测量值，具体取决于使用的版本。治疗前后以及 AVQI 和 VHI-30/VHI-10 的百分比变化之间计算了 AVQI 和 VHI-30 以及 AVQI 和 VHI-10 之间的相关性。使用 Friedman 和 Kruskal-Wallis 检验分别确定治疗前后的效果和组间差异。
78 名患者纳入分析。AVQI（χ²[1] = 24.01，P < 0.001）、VHI-30（χ²[1] = 18.00，P < 0.001）和 VHI-10（χ²[1] = 38.35，P < 0.001）的评分均显著改善。然而，AVQI 和 VHI-30 以及 AVQI 和 VHI-10 之间的相关性均无统计学意义，除了治疗前 AVQI 和 VHI-10 之间存在中度相关性（r[43] = 0.31，P = 0.04）。AVQI 和 VHI-30/VHI-10 的百分比变化无显著相关性。
嗓音治疗显著改善了声学和自我感知的嗓音结果测量。然而，在治疗前后，这些测量值之间没有显著的关系，也没有它们变化程度的关系。结果支持这样一种观点，即 VHI 和 AVQI 测量独特的结构，并且嗓音治疗可以对两者都产生积极的影响。
