N2 - The dermatology life questionnaire index (DLQI) and the Skindex are the most commonly used dermatology-specific health-related quality of life (HRQOL) instruments. Although these tools are used in international surveys and clinical trials, the cross-cultural equivalence of their items has not been documented. We used differential item functioning (DIF), which is part of the Rasch model, to assess the impact of cultural background on the items of the DLQI and Skindex-29 and-17. The data of the 450 psoriasis patients, who attended in- and outpatient dermatology centers, was collected retrospectively from five European and one US center. The DLQI and Skindex-29 scales did not fit the Rasch model (P
