Minimal clinical important difference (MCID) of the Thai Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL).
Chronic urticaria (CU) has negative impacts on patients' daily lives. The Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) evaluates quality of life impairment attitudes among chronic urticaria patients. Although the CU-Q2oL has been validated in several languages, the minimal clinical important difference (MCID) of the CU-Q2oL has never been determined. ⋯ The Thai CU-Q2oL is a valid and reliable instrument. We propose that a difference in the Thai CU-Q2oL score of 15 (MCID) is the smallest change patients perceive as a meaningful improvement.
