Abstract:
Objective:To translate the Vascular Quality of Life Questionnaire-6 (VQ6) into a Chinese version and to test its reliability and validity in patients with peripheral arterial disease.Methods:The English version of VQ6 scale was sinicized following the Brislin translation guidelines, and the Delphi consultation was used for cultural debugging to form the Chinese version of the VQ6. Convenience sampling was used to select 146 patients with peripheral arterial disease who attended the Department of Interventional and Vascular Surgery and the Department of Endocrinology of Affiliated Hospital of Nantong University from May to June 2024 for the survey. Data were analyzed using SPSS 26.0 and Amos 26.0. Correlation analysis and critical ratio method were used for item analysis and content validity index was used to evaluate content validity. The Chinese version of the Patient-Reported Outcomes Measurement Information System 29 Profile V2.1 (PROMIS-29 Profile v2.1) was selected as a validity scale to evaluate the criterion-related validity. Exploratory factor analysis and confirmatory factor analysis were used to evaluate the structural validity of the scale, and transgender test was used for measurement equivalence. Reliability of the scale was evaluated with the Cronbach's α coefficient and retest reliability index.Results:The Chinese version of the VQ6 scale had six items. The scale-level content validity index was 0.972, and the item-level content validity index ranged from 0.833 to 1.000. One common factor was extracted with a cumulative variance contribution of 83.526%. Criterion-related validity showed that the correlation coefficient between the Chinese version of the VQ6 and the PROMIS-29 Profile v2.1 was 0.688 ( P<0.01) . The scale essentially satisfied Δ RMSEA < 0.015 and Δ CFI < 0.01 in the transgender equivalence test. The Cronbach's α coefficient for the scale was 0.968 and the retest reliability was 0.978. Conclusions:The Chinese version of the VQ6 has good reliability and validity and is suitable as an assessment tool for quality of life in patients with peripheral arterial disease in our cultural context.
