title: [Validation and reliability of Turkish Singing Voice Handicap index].
abstract: OBJECTIVE
  This study aims to constitute a valid and reliable Turkish version of the original Singing Voice Handicap Index.
  
  
  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).
  
  
  CONCLUSIONS
  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.
