Introduction: The chronic obstructive pulmonary disease assessment test (CAT) is a self-administered questionnaire that measures health-related quality of life. GOLD proposes using this questionnaire, since it provides thorough coverage of the impact of chronic obstructive pulmonary disease (COPD) on well-being. This questionnaire has been widely used in daily clinical practice in Portugal, but it lacks validation for European Portuguese. The aim of this study was to carry out the cultural adaptation and validation of the CAT questionnaire so that the most appropriate version can be made available to Portuguese researchers and clinicians.
Material and Methods: A cross-sectional descriptive study was performed involving 65 patients with COPD aged 40 years or older. CAT and the previously validated Portuguese-language version of the Clinical Questionnaire for COPD were applied between January 2019 and June 2019. The agreement between the two questionnaires was determined with Kappa agreement with a 95% confidence interval. Spearman correlation was used to find the correlation between two scores.
Results: The 65 patients included in the study were observed in a hospital-based pulmonology clinic [aged 68 ± 7 years; forced expiratory volume in 1 sec (FEV1) 49.86% ± 16.5% predicted]. CAT correlated significantly with all the domains and the overall score of the CCQ (0.47 < r < 0.75; p < 0.001). The bilingual patient interclass correlation coefficient was 0.922; Pearson’s r = 0.928; p < 0.001. The Cronbach’s alpha coefficient was 0.96 (p < 0.001).
Conclusion: The European Portuguese version of the COPD Assessment Test is a valid instrument for measurement of health-related quality of life in COPD patients. The use of validated questionnaires is of great importance since it generates reliable and reproducible evidence for use either in research or clinical practice.
