Abstract: Background: There is a growing concern to measure the effect of swallowing problems on the quality of life. However, clinical measurement in this aspect was unavailable in Hong Kong. Having the Swallow Quality-of-Life Questionnaire (SWAL- QOL) which was originally developed for the English-speaking population translated into Chinese and validated in Hong Kong would help to fill in the gap and serve the aforementioned purpose. Aims: To translate the SWAL- QOL into Chinese and to validate the Chinese Swallow Quality-of-Life Questionnaire (CSWAL- QOL). Methods: A cross-cultural adaptation approach with five steps was used to translate the questionnaire from English into Chinese. With a convenience sampling, a cross-sectional survey was then launched to evaluate the validity and reliability of the CSWAL-QOL. One hundred subjects with swallowing problem were recruited to evaluate the construct validity and internal consistency and 20 subjects for the test-retest reliability. Construct validity was validated through factor analysis and a correlation study between the CSWAL-QOL and the World Health Organization Quality of Life Questionnaire- an abbreviated version [WHOQOL-BREF (HK)]. Reliability was estimated using tests of internal consistency and test-retest reliability. Results: Exploratory factor analysis of the CSWAL-QOL revealed a two-factor structure, namely the dysphagia-specific quality of life factor and the generic quality of life factor. This 2-factor model, similar to the model described by the original instrument, was confirmed by confirmatory factor analysis. The correlation between the CSWAL-QOL scores and the WHOQOL-BREF (HK) scores was fair (rs = .387 - .705, p < .05). The internal consistency of the ten scales of the CSWAL-QOL was high, except for the eating desire scale α = .75 to .95, p < .05). The test-retest reliability as estimated by the Spearman's rho was fair (rs = .57, p < .05) while the intra-rater reliability estimated by the intraclass correlation index was good (ICC= .78, p < .05). The results of this study were grossly similar to those of the English version of the SWAL-QOL, except for the result of the eating desire scale and the communication scale which showed insignificant results in the construct validity. Conclusion: The validated CSWAL-QOL is a clinically valid and reliable tool for use to assess the quality of life in dysphagic Chinese patients in Hong Kong regardless of the causes of dysphagia
