Abstract: Objective To construct the Chinese version of activity of daily living (ADL) scale for accurate assessment and provide long-term care services. Methods Convenient sampling method was used to evaluate 4590 elderly people in China with Chinese version of ADL scale and Barthel index at the same time. Descriptive analysis, exploratory factor analysis, Cronbach's α coefficients, clustering analysis, correlation analysis, paired chi square test were used to describe the scale and verify its reliability and validity. Results The Chinese version of ADL scale showed good reliability and validity, and the total score can be divided into 5 levels. The average score of ADL was 28.84±16.86. Compared with Barthel Index,The r value between corresponding items was -0.694--0.986 (P<0.01). The grade of very severe disability was used as the positive result of severe disability, and the kappa value was 0.875 (P<0.01) in paired chi square test. Conclusions The evaluation results of Chinese version of ADL scale and Barthel Index are consistent, and the accuracy of ADL scale in screening severe disability is higher, which can be widely used in the field of long-term care and pension.
