Background: The Dysphagia Handicap Index (DHI) is a 25-item questionnaire that assesses the quality of life among individuals with dysphagia. The aim of this study was to translate and validate the Kannada version of DHI (DHI-K). Method: Eighty-eight individuals with dysphagia and an equal number of healthy individuals filled out the DHI-K. Internal consistency and test–retest reproducibility were used for reliability testing. Validity was established by comparing DHI-K scores of patients with dysphagia and healthy controls. Results: The overall Cronbach’s α for DHI-K was .81, indicating good internal consistency. Cohen’s κ agreement for test–retest reliability of self-perceived severity was found to be .9. Correlation between subscales of DHI and self-perceived severity was analyzedusingSpearman correlation coefficient and was found to very high. The control group has significantly lower scores for all scales when compared to the dysphagia group (physical: t(174) = 31.74, p < .001; functional: t(174) = 32.65, p < .001; emotional: t(174) = 36.3, p < .001; total: t(174) = 34.08, p < .001). Conclusions: This study demonstrates that DHI-K has good internal consistency, test–retest reliability, and concurrent validity. The results of the study also reveal that it is a reliable and valid tool for assessment of handicap in Kannadaspeaking dysphagia population.
