Abstract
To validate the Quality of Life-Rheumatoid Arthritis Scale II (QOL-RA II) in an Argentinean cohort of patients with rheumatoid arthritis (RA). Patients ≥ 18 years old, with a diagnosis of RA according to ACR-EULAR 2010 criteria, were included in a cross-sectional study. Sociodemographic data, comorbidities, RA characteristics, disease activity, and current treatment were registered. Questionnaires were administered, including EQ-5D-3 L, QOL-RA II, HAQ-A, and PHQ-9. The QOL-RA II was re-administered in 20 patients to evaluate reproducibility. Four hundred and thirty patients were included. Median QOL-RA was 6.6 (IQR 5.3–8). Mean time to complete it was 1.7 ± 0.57 min and to calculate it was 12 ± 1.7 s. It showed very good reliability (Cronbach’s alpha 0.97), reproducibility (ICC, 0.96), and good correlation between the different items and the total questionnaire, without evidence of redundancy. Besides, QOL-RA II presented good correlation with EQ-5D-3L (Rho, 0.6) and moderate with DAS28 (Rho, 0.38), and CDAI (Rho, 0.46). Worse quality of life was observed in patients not doing physical activity, unemployed, and current smokers. Patients with higher disease activity had a significant poorer quality of life. Adjusting by age, sex and disease duration, unemployment, higher disease activity, disability, and the presence of depression were independently associated to worse quality of life. QOL-RA II demonstrated good construct validity, reproducibility, and reliability. It was easy to complete and calculate and does not require a license for its use, thus making it the optimal tool for assessing the quality of life in Spanish-speaking patients with RA.
Key Points • The evaluation of quality of life is very important in patients with Rheumatoid Arthritis. • Most of the questionnaires used to assess the quality of life require a license to use. • QOL-RA II is a valid and simple questionnaire to evaluate the quality of life of patients with RA and does not require a license for its use. |
