Cholinergic Urticaria Quality of Life Questionnaire (CholU-QoL)
The Quality of Life Questionnaire for Patients with Cholinergic Urticaria (CholU-QoL) is the first and only available quality of life questionnaire specifically designed for patients with cholinergic urticaria. CholU-QoL is easy to use and has been validated specifically for patients with cholinergic urticaria.
The CholU-QoL was developed at the Charité by a team headed by Dr. Sabine Altrichter, PD Dr. Karsten Weller and Prof. Marcus Maurer. Initially, 96 questions were created using established procedures and in accordance with international recommendations. Using impact and factor analyses as well as visual validity testing, 28 of these questions were selected for the final CholU-QoL instrument. This instrument was then checked for validity and reliability and examined with regard to possible influencing factors.
