Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) is the only available and validated disease specific questionnaire in the assessment of QoL in CU patients originally developed in Italian language. The aim of the current study was to develop the Persian version of the CU-Q2oL with an acceptable reliability and validity.Using the standard methods provided by guidelines, CU-Q2oL was translated into Persian. A total number of 110 patients with confirmed diagnosis of CU were asked to fill the questionnaire.
