About

VascuQol (VQ) is a specific questionnaire to assess the quality of life of patients with critical limb ischemia which is also used as an index in vascular registries. The original version has 25 items (VQ-25), divided into 5 subscales or domains: pain, symptoms, activity, social and emotional. The shortened version, VascuQol-6 (VQ-6) is made up of 6 questions and 4 possible answers, which score from 1 (worst quality of life perceived by the patient) to 4 (best quality of life perceived by the patient). The total score is between 6 and 24, and a higher value is related to better health.

While the VQ-25 questionnaire has been translated and validated in 21 languages, the shortened version VQ-6 has been translated and validated in some languages, not including Spanish. As it is a fast and easy-to-use tool iwhich has demonstrated statistical validation to measure PAD in other versions of the same questionnaire (other languages), a cross-cultural adaptation and statistical validation of the questionnaire from English to Spanish will be carried out.
