Peripheral Arterial Disease (PAD) is a prevalent condition that predisposes the patients to major cardiovascular events. The majority of patients are asymptomatic, however PAD has a great impact in the patients' lifestyle due to its chronic nature. The Peripheral Arterial Questionnaire (PAQ) is a validated tool to quantify the patients' subjective experience of the disease. The aim of this work is to validate the Portuguese version of PAQ. A retrospective study of 59 patients with aortoiliac disease Trans-Atlantic Inter Society Consensus (TASC) type D from two centers in Portugal was conducted. Only 36 patients were able to answer the PAQ and two Portuguese validated questionnaires - a disease-specific (Walk Impairment Questionnaire - WIQ) and a generic one (EuroQol 5 dimensions - 5 level EQ5D-5L). Con- vergent validity of the PAQ was evaluated by correlating the extracted PAQ subscales and Summary score with the WIQ subscales and summary score, as with EQ5D-5L Summary score and EQ5D-5L index by calculating the covariance. The Portuguese version of the peripheral artery questionnaire presented a Cronbach's α for the Summary scale of 0.913. Mean inter-item correlation for the Physical Function domain was 0.471, 0.551 for the Perceived Disability, and 0.464 for Treat- ment Satisfaction. In summary, the Portuguese version of PAQ demonstrated a good level of discrimination between patients with or without symptomatic PAD and its severity and was sensitive to the presence of risk-factors relevant for PAD.
