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 ( = 0.00). Internal consistency for all the nine domains of KSWAL-QOL measured using Cronbach's α ranged from 0.89 to 0.92, demonstrating excellent reliability. Test-retest measures were exceptional, with Intraclass Correlation Coefficient (ICC) ranging between 0.92 and 0.98 and Spearman's rho values between 0.91 and 0.97. A very strong negative correlation was obtained between KSWAL-QOL and DHI-K, and a strong positive correlation was seen between KSWAL-QOL and LISAT. The KSWAL-QOL is a reliable and valid tool with excellent psychometric properties to evaluate the quality of life associated with swallowing in individuals with oropharyngeal dysphagia.

吞咽生活质量（SWAL-QOL）问卷是评估吞咽困难对生活质量影响的常用工具。SWAL-QOL已被翻译成多种语言并经过验证。在印度语言中，尚无有效的吞咽困难特异性生活质量工具。因此，本研究旨在对SWAL-QOL进行文化调适、翻译并验证其在印度南部达罗毗荼语系的卡纳达语中的版本（KSWAL-QOL）。采用标准翻译程序将原始的SWAL-QOL翻译成卡纳达语。本研究招募了55名口咽吞咽困难患者（临床组）和55名吞咽能力正常的参与者（对照组），以评估KSWAL-QOL的有效性和可靠性。使用吞咽障碍 handicap指数 - 卡纳达语版本（DHI-K）和生活满意度问卷（LISAT）来检验KSWAL-QOL的收敛效度。KSWAL-QOL在所有领域均表现出出色的判别效度，能够区分临床组和对照组（= 0.00）。使用Cronbach's α测量的KSWAL-QOL九个领域的内部一致性范围为0.89至0.92，显示出出色的可靠性。重测结果优异，组内相关系数（ICC）在0.92至0.98之间，Spearman's rho值在0.91至0.97之间。KSWAL-QOL与DHI-K之间存在非常强的负相关，与LISAT之间存在强正相关。KSWAL-QOL是一种可靠且有效的工具，具有出色的心理测量特性，可用于评估口咽吞咽困难个体的吞咽相关生活质量。
