The VHI-10 and VHI Item Reduction Translations—Are we all Speaking the Same Language?

The Vocal Handicap Index-10 (VHI-10) was designed as an item reduction of the original VHI to provide a quick, reliable, and quantifiable measure of patients' own vocal handicap perception. Many translations of the VHI-10 have been produced, but methodologies of translation vary between articles and do not always mirror that of the English VHI-10. This discrepancy leads to confusion about normative values and the applicability of published data in non–English-speaking cultures. This article examines the various item reductions of the VHI-10 from the VHI and the differing methodologies of translation of the VHI-10.
