Cross-Cultural Adaptation, Translation and Validation of Kannada Version of the Swallowing Quality of Life Questionnaire (KSWAL-QOL).

The swallowing quality of life (SWAL-QOL) questionnaire is a commonly used tool to assess the impact of dysphagia on quality of life. SWAL-QOL has been translated and validated in many languages. There is no valid dysphagia-specific quality of life tool in Indian languages. Hence, the current study aimed at cultural adaptation, translation, and validation of SWAL-QOL in Kannada (KSWAL-QOL), a south Indian Dravidian language. The original SWAL-QOL was translated into Kannada using the standard translation procedure. A group of 55 participants with oro-pharyngeal dysphagia (clinical group) and 55 participants with normal swallowing abilities (control group) were recruited for the current study to assess the validity and reliability of KSWAL-QOL. Dysphagia Handicap Index- Kannada version (DHI-K) and Life Satisfaction Questionnaire (LISAT) were used to check for the convergent validity of the KSWAL-QOL. The KSWAL-QOL demonstrated excellent discriminant validity and distinguished clinical from the control group across all domains ( The online version contains supplementary material available at 10.1007/s12070-023-04162-w.
