Abstract

OBJECTIVES: This study aims to constitute a valid and reliable Turkish version of the original Singing Voice Handicap Index.PATIENTS AND METHODS: An authorized committee assessed the reliability and validity of the content, scope, and language of the original Singing Voice Handicap Index which underwent a back translation process. The Turkish version of the questionnaire was answered twice with a 7 to 10-day interval by two singing voice groups with or without singing voice problems. The reliability and validity analyses were performed based on these answers.RESULTS: Of a total of 123 individuals (64 females, 59 males; mean age 26.2±7.3 years), 81 were without a voice pathology and 42 were with a voice pathology. The total Cronbach's alpha coefficient was 0.917. The item-total correlations ranged between 0.51 and 0.89. The weighted kappa values of test-retest correlation values of the items were 0.82-0.91. The Cronbach's alpha values of two part of the questionnaire based on the split-half method were 0.89 and 0.84. The mean total scale scores were 21.8±18.5 and 53.6±28.9 in normal and pathology groups, respectively and there was a statistically significant difference in scores between these two groups (p=0.000).CONCLUSION: The Turkish version of the Singing Voice Handicap Index is a valid and reliable scale which can be used in the evaluation of voice problems of Turkish-speaking singing voice users.
