The validation of the Chinese version of the Swallow Quality-of-Life Questionnaire (SWAL-QOL) using exploratory and confirmatory factor analysis.
The aim of this work was to study the psychometric properties of the Chinese version of the Swallow Quality-of-Life Questionnaire (CSWAL-QOL) validated in the Hong Kong Chinese-speaking population. With convenience sampling, a cross-sectional survey was launched to evaluate the validity and reliability of the CSWAL-QOL. One hundred subjects with swallowing problems were recruited to evaluate the construct validity and internal consistency, and 20 subjects were recruited for the test-retest reliability. Construct validity was validated through factor analysis (both exploratory and confirmatory) and a correlation study between the CSWAL-QOL and the World Health Organization Quality-of-Life Questionnaire-abbreviated version [WHOQOL-BREF (HK)]. Reliability was estimated using tests of internal consistency and test-retest reliability. The psychometric properties of the CSWAL-QOL were found to be largely similar to those of the SWAL-QOL, except the three-item eating desire scale of the CSWAL-QOL, which showed insignificant results in the validity and reliability tests. The CSWAL-QOL is the first validated Chinese version of the SWAL-QOL in Hong Kong. It is a clinically valid and reliable tool for assessing the quality of life in dysphagic Chinese patients in Hong Kong, regardless of the causes of dysphagia.
