Responsiveness of the CCVUQ-Br quality of life questionnaire in chronic venous ulcer patients.

Background: Responsiveness is a measure of an instrument's ability to reflect in its score the variability that has occurred in a patient's life as a result of an intervention. The CCVUQ-Br has been validated in Portuguese, but its responsiveness still needs to be tested. When this study has been completed, the CCVUQ-Br will be available for use as an instrument capable of detecting and reflecting in its score the changes that take place in the quality of life of people with venous ulcers.

Determination of the longitudinal sensitivity of the AVVQ-Brazil Quality of Life Questionnaire to non-surgical treatment of chronic venous disease.

Background: Sensitivity determines the efficiency and quality of construction of an assessment measure, but studies of the subject are scarce in the literature.

Objective: To evaluate the longitudinal sensitivity of the AVVQ-Brazil to clinical changes after treatment for chronic venous disease (CVD).

Methods: A longitudinal intervention study, with 112 chronic venous patients receiving elective treatment, assessed with CEAP, VAPS, AVVQ-Brazil, and VEINES-QOL/Sym at pre-treatment (baseline) and post-treatment (4 weeks).
