BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing dermatosis. Previous studies have focused mostly on pediatric patients, and investigations emphasizing adult AD have been limited. OBJECTIVE: We set out to determine the 1-year prevalence and evaluate the validity of the International Study of Asthma and Allergies in Childhood (ISAAC) and United Kingdom Working Party (UKWP) AD questionnaires of adult AD in Taiwan. METHODS: We conducted a cross-sectional study among nursing staff at a university hospital. The 1-year prevalence of AD was assessed by ISAAC and UKWP questionnaires. Subsequently, the dermatologists' diagnosis based on Hanifin and Rajka criteria was used as a reference for validation. RESULTS: The overall response rate was 92.9%, equivalent to 1131 complete questionnaires. Ninety adult patients with AD (8%) were identified by dermatologists' diagnosis whereas ISAAC identified 107 (9.5%); sensitivity and specificity were 36.7% and 92.9%, respectively. UKWP identified 42 (3.7%) patients with AD; sensitivity and specificity were 42.2% and 99.6%, respectively. Using the receiver operating characteristic curve analysis, the UKWP criteria performed significantly better than its ISAAC counterpart. Further analysis indicated that modification of these criteria resulted in significant improvement in their diagnostic efficacy. More specifically, modified ISAAC showed 90.0% and 55.2% sensitivity and specificity, respectively, whereas modified UKWP demonstrated 82.2% and 94.2% sensitivity and specificity, respectively. LIMITATION: Most of the study subjects were female with a high educational background. CONCLUSION: Currently available questionnaire instruments do not perform well in the identification of adult patients with AD. Modification of the original questionnaires may allow for future large-scale epidemiologic studies.
