Abstract
ObjectiveTo translate and revise the Arteriovenous Fistula Assessment Scale (AVF-AS), test the reliability and validity of the Chinese version of AVF-AS.
MethodsThe modified Brislin translation model was used to translate, back translate and cross culture adjust AVF-AS, forming the Chinese version of AVF-AS. Using the convenient sampling method, 220 hemodialysis patients from the First Affiliated Hospital of Zhengzhou University were selected for investigation from July to September 2022. Two weeks later, 30 patients were randomly selected for retesting. The valid data were used for project analysis and reliability and validity evaluation.
ResultsThe Chinese version of AVF-AS consisted of 3 factors and 18 items. Consistency level between evaluators was 0.94, the item level content validity index was 0.83-1.00, average scale level content validity index was 0.94, and the calibration validity was 0.68.Three common factors(autogenous arteriovenous fistula blood flow, stenosis and ischemia, puncture location) were extracted from exploratory factors, and the cumulative variance contribution rate was 75.255%. The total scale's Cronbach α was 0.946, the half reliability of each dimension was 0.826 - 0.898, and the test-retest reliability was 0.907.
ConclusionsThe Chinese version of AVF-AS has good reliability and validity, and can be used as an effective tool to evaluate the autogenous arteriovenous fistula functional status of hemodialysis patients in China.
