Background: There is a need for validated tools to assess health-related quality of life (HRQoL) in routine clinical practice. Objective: The aim of this study was to validate the Chronic Urticaria Patient Perspective (CUPP) for assessment of patients with chronic urticaria (CU) in clinical practice. Methods: A provisional CUPP was developed from candidate items identified by following an iterative process in a retrospective analysis of 249 Chronic Urticaria Quality of Life Questionnaire questionnaires. The psychometric properties of the CUPP were then tested on a sample of patients enrolled in 13 Italian centers. Results: The study population in the validation phase comprised 152 patients. The 10-item version of the CUPP showed satisfactory internal consistency (Cronbach's alpha values of 0.76 at visit 1 and 0.90 at visit 2), good criteria, and discriminative and convergent validity. Reliability was assessed in 34 patients with no changes in health (Global Rating Scale = 0 at visit 2) and was satisfactory (CCC [concordance correlation coefficient] = 0.9). Changes in CUPP scores were significantly associated with changes in Urticaria Activity Score (UAS)-Hive count (r = 0.36, P < .001), UAS-Itch severity (r = 0.48, P < .001), and UAS-Total score (r = 0.342, P < .001), all of which indicated good responsiveness. The minimal important difference was 1.5. Conclusions: CUPP is a simple 10-question tool with good psychometric properties that provides a valid, reliable, and standardized measurement of HRQoL in patients with CU.
