Abstract

Quality of life (QOL) assessments are not standardized in atopic dermatitis (AD). We sought to determine the validity of Short-Form 12 (SF-12), a generic QOL assessment, in AD and compare its measurement properties with Dermatology Life Quality Index (DLQI). A cross-sectional, population-based study of 3495 adults was performed, including 602 that met a modified UK Working Party Criteria for AD. SF-12 mental component score (MCS) and SF-6D had a strong correlation with each other, and moderate inverse correlations with Patient-Oriented Eczema Measure, Patient Oriented-Scoring AD (PO-SCORAD), PO-SCORAD–itch, PO-SCORAD-sleep, and numerical rating scale of pain (Pearson correlations, P
