Keywords Chronic venous disease CIVIQ Health Objective Construction of a stable and psychometrically Quality of life Well-being validated questionnaire from CIVIQ-20. Methods and major findings A prospective, international study was used to construct a stable CIVIQ scale and to Introduction validate its psychometric properties. An iterative process was implemented to eliminate the more unstable items Several disease-specific quality of life instruments have (six), and the social and physical dimensions were com- been developed for use in patients with chronic venous bined. The resulting instrument comprised 14 items, split disease (CVD), each with their own strengths and weak- into three dimensions (pain, physical, and psychological), nesses [ 1].
