Abstract
The purpose of this study was to validate the Chinese version of the Nottingham Eczema Severity Score (NESS) in determining the severity of atopic dermatitis (AD). Each parent or patient filled out a questionnaire in Chinese based on the NESS. A physician then repeated the NESS independently. Finally, the severity of AD was evaluated according to the Scoring Atopic Dermatitis (SCORAD) scale. The NESSs, severity grades, and SCORAD were analyzed for agreement and correlation. The severity grading agreed with the physician's grading in 38 of 52 parents (73%) and in 16 of 18 children (89%) who self‐evaluated the severity of their AD. The weighted kappa (95% confidence interval [CI]) for parents with children less than 10 years old, parents with children ≥10 years old, and patients who self‐evaluated their AD were 0.79 (0.66–0.91), 0.85 (0.69–1.00), and 0.74 (0.36–1.00), respectively. The R2 for the NESS by parents, the NESS by patients, and the SCORAD scores was 42.1%, 47.5%, and 49.8%, respectively. When compared with the parents, the older children who self‐evaluated their AD showed a better correlation of the NESS with the SCORAD index. The self‐administered questionnaire appears to be useful in assessing AD severity in Chinese children.
