Introduction

The Voice Handicap Index has been shown to be a valid instrument for assessing self-perceived handicap associated with dysphonia.

Objectives

To test the psychometric properties of the Spanish version of the VHI-30 (Voice Handicap Index) and its shortened version VHI-10.

Subjects and method

The original VHI-30 was translated into Spanish and was completed by 232 dysphonic patients and 38 non-dysphonic individuals. Prospective instrument validation was performed.

Results

Results showed high test-retest reliability, and high item-total correlation for both Spanish VHI-30 and VHI-10. Internal consistency demonstrated to Cronbach's alpha of .93 and .86 respectively, and a significant correlation was found between the VHI scores and the patients’ self-rated dysphonic severity.

Conclusions

The present study supports the use of Spanish versions of VHI-30 and VHI-10 because of their validity and reliability.

Introducción y objetivos

El índice de incapacidad vocal (Voice Handicap Index) es un instrumento válido para la valoración del menoscabo asociado a la disfonía que percibe el paciente. El objetivo es valorar las propiedades psicométricas de la versión castellana del VHI-30 y su versión abreviada VHI-10.

Sujetos y método

El VHI-30 original se tradujo al idioma español y lo contestaron 232 pacientes con disfonía y 38 sujetos sanos. Se realizó una validación prospectiva del instrumento.

Resultados

Se encuentra una alta fiabilidad test-retest y altas correlaciones ítem-total tanto para el VHI-30 como para el VHI-10. La coherencia interna demuestra valores alfa de Cronbach de 0,93 y 0,86 respectivamente, y se encontró una correlación significativa entre las puntuaciones del VHI y la valoración de los pacientes de la severidad de su disfonía.

Conclusiones

El presente estudio apoya el uso de las versiones en español del VHI-30 y del VHI-10 por su validez y fiabilidad.
