The aim of present study is to translate and validate a Chinese version of the WIQ in patients with PAD and T2DM. A cross-sectional survey was conducted. After translation, a convenience sample of 59 patients with PAD and T2DM completed the Chinese WIQ, the Chinese SF-36 and the 6MWT. The ICC and Cronbach’s alpha were calculated to determine the reliability and internal consistency, respectively.Validity was evaluated by correlation coefficients between WIQ, SF-36 and 6MWD. The internal consistency determined by Cronbach’s alpha was 0.93. Test—retest reliability expressed by ICC was 0.93. Significant correlations were observed between WIQ, SF-36 and 6MWD (ρ s =0.27 ∼0.88, p < 0.01).The Chinese version of the WIQ has satisfactory reliability and validity and can be used to assess walking ability in type 2 diabetic PAD patients.
