    Abstract

    Background. Chronic urticaria (CU) is a common skin disorder that affects the well-being and quality of life (QOL) of patients. Recently, we developed and validated a questionnaire for measuring QOL in Korean patients with CU, called the Chronic Urticaria-Specific Quality of Life (CU-QOL) questionnaire. Aim. To evaluate the clinical significance of a computerized version of the CU-QOL, in adult patients with CU. Methods. This was a cross-sectional observational study that enrolled 249 Korean patients with CU from five university hospitals and measured computerized CU-QOL scores and Urticaria Activity Score (UAS) simultaneously. The internal consistency of the computerized CU-QOL was analysed using Cronbach α. To identify clinical correlations between the CU-QOL and patient characteristics, the atopic status and serum autoantibodies, including antinuclear, antithyroglobulin and antimicrosome antibodies, were measured. Multiple linear regression models were used to identify CU-QOL predictors. Results. Cronbach α was 0.94 for the overall computerized CU-QOL score. The CU-QOL scores correlated significantly with the UAS (r = -0.49, P < 0.001). Of the factors aggravating CU, delayed pressure, sunlight exposure and emotional stress significantly influenced the overall CU-QOL scores in the univariate analysis. Multivariate regression models indicated that UAS and emotional stress were significant predictors of the four domains and of the total CU-QOL scores. Conclusions. The computerized CU-QOL is a convenient and valid tool for measuring QOL in patients with CU. This study suggests that UAS, dermatographism and emotional stress are strong CU-QOL predictors in Korean patients with CU.
