Index of pediatric voice handicap: Translation, transculturalization and validation to Argentinian Spanish

Objective: Voice disorders are very common in the pediatric population, with 6% and 23% of all children presenting with some form of dysphonia [1,2]. For many years, these patients have been underdiagnosed. There has been increasing awareness and interest in the study of voice alterations in children, and, most importantly, their impact in their quality of life. To do this, an instrument capable of measuring the quality of life in pediatric patients with vocal pathology is required, which can be used extensively in the scientific community. The objective of our study is to carry out the translation, transculturalization and validation of pVHI (Pediatric Voice Handicap Index) to Argentinian Spanish-speakers. Material and methods: A study was carried out in the Hospital de Pediatria Dr. JP Garrahan in the city of Buenos Aires, Argentina. It included patients between 3 and 18 years old. The pVHI was translated and transculturalized for said population and for its validation, a survey was carried out in two groups of patients: one group being children with a background of both reconstructive larynx surgery, and dysphonia (n = 35) and the other group being control patients, without any voice pathology (n = 35). The survey was conducted among either parents or caregivers of the children in question. Results: A significant difference was found between both groups, for both overall pVHI score and survey subgroups score (p < 0.001) with an optimal internal confidence and a good Alpha Cronbach for each of the subgroups (functional 0,92; organic 0,87 and emotional 0,88). Test-retest for reliability revealed "p-values" without any significant difference (p > 0.05) for each of all subgroups (functional 0,68; organic 0,32 and emotional 0,72). Conclusion: The validation and transculturalization of the rate of pediatric vocal impairment to Argentinian Spanish population presented an adequate validity and reliability. The rate of pediatric vocal impairment was identified through this simple and practical survey, offering additional information on the child's own vocal perception by part of the caregiver. We recommend this survey being included as a valuable tool in the evaluation of pediatric dysphonia in Spanish-speaking families.
