Outline
Swallowing disorders have a high incidence among patients with cognitive dysfunction and significantly impact their quality of life. The Swallowing Quality of Life questionnaire (SWAL−QOL), a widely used tool for assessing swallowing function and related quality of life, has previously excluded individuals with Mild to moderate cognitive dysfunction from its applicable population in prior studies. This study is the first to systematically validate the applicability of the Chinese version of SWAL−QOL in patients with cognitive dysfunction. The research included 122 patients with Mild to moderate cognitive dysfunction, and explored the inter−rater reliability, internal consistency reliability, content validity and construct validity of the results among the participants. The results demonstrated that the inter−rater reliability coefficients for each dimension (except for the food choice dimension) were all above 0.8, and the overall internal consistency Cronbach's α value reached 0.971. The construct validity analysis showed that the scale was significantly correlated with swallowing function assessment tools such as the Kubota Water Swallowing Test and the EAT−10 scale. Three common factors were extracted: psychosocial function, nutritional intake patterns, and physiological function regulation (cumulative variance contribution rate of 72.742%), revealing the multidimensional impact of dysphagia on patients' psychological, physiological, and social functions. Research indicates that the Chinese version of the SWAL−QOL scale can serve as a reliable assessment tool for swallowing−related quality of life in patients with Mild to moderate cognitive dysfunction, providing theoretical support for the development of individualized intervention strategies and the enhancement of patients' quality of life.
