Voice Handicap Index-18 as an Instrument for Assessing Subjective Voice Impairment Between Voice Pre- and Post-treatment.

The Voice Handicap Index (VHI) is today regarded as the gold standard for measuring the subjective impairment of a voice disorder. The aim of our study is to present how the VHI in our version with 18 questions (VHI-18) can be evaluated with other patient collectives (practice visitors or everyday patients). The previous publications have shown that most patient groups were stationary or clinical. A total of 100 adult patients (72 female, 28 male) in our medical practice KOPFZENTRUM were examined. The reliability of the VHI-18 results from a Cronbach's Alpha (0.92). The VHI-18 is suitable as a diagnostic instrument for medical practices or logopaedic practices.
