Abstract
Dermatology-specific quality-of-life instruments such Dermatology Life Quality Index (DLQI), as well as vitiligo-specific instruments are available to study the quality of life of patients with vitiligo. Vitiligo Impact Scale (VIS)-22 is a validated vitiligo-specific instrument, and clinical meaning has been assigned to its absolute scores.1,2 The minimal important change (MIC) is the smallest difference in a score that is considered significant by the patient and/or physician. We conducted this study to determine the MIC scores of VIS-22 as well as DLQI scores in vitiligo.
