This study aimed to assess the reliability and validity of the Persian version of the Pediatric Voice Handicap Index (pVHI).
The questionnaire was translated into Persian and then administrated to the parents of 45 dysphonic children and parents of 135 normal children. The content validity of the questionnaire was confirmed by eight speech-language pathologists. Internal consistency and test-retest reliability were measured via Cronbach's alpha and intra-class correlation coefficient, respectively. Independent-samples t-test was used to evaluate the discriminative and clinical validity of Persian pVHI.
Cronbach's coefficient values were excellent for the total score (α = 0.94) and physical subcomponent (α = 0.91). Moreover, these corresponding values were satisfactory for functional (α = 0.82) and emotional (α = 0.79) subcomponents. Test-retest reliability for the total score was high in both dysphonic and control groups (intra-class correlation coefficient> 0.92). There were significant differences between the control and dysphonic groups in terms of the total score and all subcomponents scores of Persian pVHI. However, no significant difference was observed in the mean total score of the Persian pVHI between the control and dysphonic group regarding gender (P < 0.001).
Persian version of pVHI is a valid and reliable tool to evaluate the severity of voice disorder and its negative effects on the daily life of Persian children with voice disorder from the Parents' viewpoint.
本研究旨在评估小儿嗓音障碍指数量表（pVHI）波斯语版本的信度和效度。
问卷被翻译为波斯语，然后由 45 名发音障碍儿童的家长和 135 名正常儿童的家长填写。问卷的内容效度由 8 名言语语言病理学家确认。内部一致性和重测信度分别通过 Cronbach's alpha 和组内相关系数进行测量。独立样本 t 检验用于评估波斯语 pVHI 的判别和临床有效性。
总分（α=0.94）和生理分量表（α=0.91）的 Cronbach's 系数值为优秀。此外，功能分量表（α=0.82）和情感分量表（α=0.79）的相应值也令人满意。在发音障碍组和对照组中，总分的重测信度均较高（组内相关系数>0.92）。在波斯语 pVHI 的总分和所有分量表得分方面，对照组和发音障碍组之间存在显著差异。然而，在发音障碍组和对照组中，波斯语 pVHI 的总分均值在性别方面无显著差异（P<0.001）。
波斯语版的 pVHI 是一种有效且可靠的工具，可从家长的角度评估有嗓音障碍的伊朗儿童的嗓音障碍严重程度及其对日常生活的负面影响。
