Voice handicap in singers.

The study aimed to determine the differences in responses to the Voice Handicap Index (VHI-10) between singers and nonsingers and to evaluate the ranked order differences of the VHI-10 statements for both groups. The VHI-10 was modified to include statements related to the singing voice for comparison to the original VHI-10. Thirty-five nonsingers with documented voice disorders responded to the VHI-10. A second group, consisting of 35 singers with voice complaints, responded to the VHI-10 with three statements added specifically addressing the singing voice. Data from both groups were analyzed in terms of overall subject self-rating of voice handicap and the rank order of statements from least to most important. The difference between the mean VHI-10 for the singers and nonsingers was not statistically significant, thus, supporting the validity of the VHI-10. However, the 10 statements were ranked differently in terms of their importance by both groups. In addition, when three statements related specifically to the singing voice were substituted in the original VHI-10, the singers judged their voice problem to be more severe than when using the original VHI-10. The type of statements used to assess self-perception of voice handicap may be related to the subject population. Singers with voice problems do not rate their voices to be more handicapped than nonsingers unless statements related specifically to singing are included.
