The aim of this study was to investigate differences and correlations between the pediatric Voice Handicap Index (pVHI) and the pediatric Voice-Related Quality-of-life (pVRQOL) questionnaires in children with and without voice disorders. This was a cross-sectional study.A total of 418 parents with children aged 2 to 14 years participated in this study from May 2016 to July 2017. This included 221 parents of children with voice disorders (dysphonic group) and 197 parents of children without voice disorders (control group). The scores for the pVHI and the pVRQOL were compared, and correlation analysis was performed.Compared with the control group, the dysphonic group had a significantly higher total score and subscale scores for the pVHI (P < .001), and significantly lower pVRQOL scores (P < .001). The pVHI showed greater differences in subscale scores among the three dysphonic subgroups than the pVRQOL. The Spearman correlation coefficient between the pVHI and pVRQOL was -0.844 (P < .001). The total scores for the pVHI and pVRQOL also correlated significantly for each diagnostic category (P < .001).Voice-related quality of life was poorer in children with voice disorders than in those without voice disorders. The pVHI and pVRQOL scores were moderately- to strongly correlated. These may be useful tools for assessing the voice-related quality of life in children. The pVHI may provide more useful details about the effects of different types of voice disorders on the voice-related quality of life than the pVRQOL.
本研究旨在调查有嗓音障碍和无嗓音障碍儿童的儿童嗓音障碍指数（pVHI）与儿童嗓音相关生活质量（pVRQOL）问卷之间的差异及相关性。这是一项横断面研究。2016年5月至2017年7月，共有418名2至14岁儿童的家长参与了本研究。其中包括221名嗓音障碍儿童的家长（嗓音障碍组）和197名无嗓音障碍儿童的家长（对照组）。比较了pVHI和pVRQOL的得分，并进行了相关性分析。与对照组相比，嗓音障碍组的pVHI总分及各子量表得分显著更高（P<0.001），而pVRQOL得分显著更低（P<0.001）。与pVRQOL相比，pVHI在三个嗓音障碍亚组的子量表得分上差异更大。pVHI与pVRQOL之间的Spearman相关系数为-0.844（P<0.001）。每个诊断类别的pVHI和pVRQOL总分也显著相关（P<0.001）。有嗓音障碍儿童的嗓音相关生活质量比无嗓音障碍儿童更差。pVHI和pVRQOL得分呈中度至高度相关。这些可能是评估儿童嗓音相关生活质量的有用工具。与pVRQOL相比，pVHI可能能提供更多关于不同类型嗓音障碍对嗓音相关生活质量影响的有用细节。
