Cross-Cultural Adaptation and Validation of the Persian Version of the Children's Voice Handicap Index-10 for Parents.

Objectives: This study aimed to translate and evaluate the psychometric properties of the Children's Voice Handicap Index-10 for Parents (CVHI-10-P) in Persian for assessing voice-related quality of life in Persian-speaking children.

Methods: The CVHI-10-P was translated into Persian and assessed for face and content validity by a panel of speech-language pathologists. The questionnaire was administered to 141 children aged 6-11 years, including 35 with voice disorders and 106 without. Reliability was measured using Cronbach's alpha, Spearman-Brown, and Guttman coefficients. Validity was evaluated through sensitivity, specificity, accuracy, precision, F-score metrics, and correlations with the Persian version of the Pediatric Voice Handicap Index (PVHI).

Results: The translated CVHI-10-P demonstrated high reliability, with a Cronbach's alpha of 0.944 for the total score. Significant differences in CVHI scores between children with and without voice disorders confirmed the questionnaire's ability to distinguish between these groups. Receiver operating characteristic (ROC) curve analysis revealed an area under the curve (AUC) of 0.974, indicating excellent diagnostic accuracy. Pearson's correlation showed strong associations between CVHI and PVHI scores across all dimensions.

Conclusion: The Persian version of the CVHI-10-P is a reliable and valid tool for assessing the impact of voice disorders on the quality of life in Persian-speaking children. It offers a concise and effective means for parents to report their children's voice-related challenges.
