Abstract: Background: The Vascular Quality of Life Questionnaire (VascuQoL-6) was proposed to evaluate specific quality of life of peripheral artery disease (PAD) patients. However, there is no Brazilian-Portuguese version available, blunting its use in Brazilian patients. The objective of the study was to analyze the psychometric properties of a translated Brazilian-Portuguese version of VascuQoL-6 in Brazilian patients with PAD with intermittent claudication symptoms. Methods: One hundred eleven patients with PAD participated in the study. After translation and retranslation, construct validity was analyzed by identifying correlation between VascuQoL-6 scores, general World Health Organization qualify of life (WHOQOL) score, and subjective and objective functional capacity tests. To determine the reliability, internal consistency and test-retest reliability with at least 7 days interval between 2 questionnaire applications were calculated. Results: Significant correlations between the VascuQoL-6 score and total WHOQOL score (r = 0.44; P < 0.05) were observed. Moreover, we observed negative correlations between the VascuQoL-6 score and 4-meter usual pace (r = -0.33; P < 0.05) and 4-meter fast pace (r = -0.34; P < 0.05) and positive correlation with onset claudication distance (r = 0.39; P < 0.05) and total walking distance (r = 0.29; P <= 0.05). Internal consistency was 0.84, whereas the intraclass coefficient correlation was 0.84, with no differences in VascuQoL-6 scores between the 2 applications days. Conclusions: The Brazilian-Portuguese version of the VascuQoL-6 presents adequate valid and reliability indicators, allowing its use in patients with PAD with intermittent claudication symptoms.
