Development and standardization of voice handicap index (VHI) in the Indian language Kannada
Background: Voice is defined as the laryngeal modulation of pulmonary airstream further modified by the vocal tract. Voice Handicap Inventory (VHI) is one of the most commonly used scales to measure the impact of voice related disorders on the emotional, functional and physical well being of an individual. Objectives: India being a multilingual country needs to develop such scales in the native languages. So the current study focused on developing and standardizing VHI to a native Indian language (Kannada). Materials & Methods: The English version of VHI was translated to Kannada by a well qualified Kannada professor. The translated questionnaire was then given to 30 native Kannada speakers for content validity. The final version of VHI-K was administered on 50 subjects who had some kind of voice problem. The data was then taken for statistical analysis. Results: After the statistical analysis, it was observed that the VHI-K has a Cronbach’s alpha score of 0.972 on standardized item which is presumed to have an excellent internal consistency. Cronbach’s alpha score for emotional, functional and physical subscales was 0.929, 0.931 and 0.925 respectively. Conclusion: Scores of Cronbach’s alpha score shows that, VHI-K has got an excellent internal consistency. The questionnaire could efficiently measure the impact of voice related disorders on the emotional, functional and physical well being of an individual.
