Adaptation and Validation of the Mandarin Chinese Version of the Pediatric Voice Handicap Index-10 (pVHI-10)

Objectives. The purpose of this study was to adapt and validate the Mandarin Chinese version of the pediatric Voice Handicap Index -10 (pVHI-10). Methods. A cross-sectional study was conducted from January 2018 to December 2019. A total of 422 parents completed the questionnaire, including 283 parents of children with voice disorders (dysphonic group) and 139 parents of children without voice disorders (control group). Internal consistency, test-retest reliability, clinical effectiveness, and cut -off value were evaluated. Results. In the dysphonic group, the internal consistency of the Mandarin Chinese version of pVHI-10 was excellent (Cronbach's a = 0.95). The test-retest reliability was excellent for the total score of the Mandarin Chinese version of pVHI-10 (interclass correlation coefficient = 0.916). The total scores as well as scores on individual items were significantly higher in the dyphonic group compared to those in the control group (P <0.001). In addition, the optimum cut -off value for the Mandarin Chinese version of pVHI-10 was 6.5 (87% sensitivity and 86.3% specificity, respectively). Conclusion. The Mandarin Chinese version of the pVHI-10 is a valid tool that evaluates the quality of life of children with voice disorders from the parents' perspective.
