【 摘 要 】

Background: There is a lack of short-form questionnaires evaluating the burden of vitiligo according to skin phototype. Objective: To develop and validate a 12-item short-form of the Vitiligo Impact Patient scale (VIPs) that takes into account skin phototype. Methods: Multicenter, prospective, cross-sectional study conducted in France (Creteil and Bordeaux) and the US (Worcester, Massachusetts, and Dallas, Texas). Results: In total, 891 patients completed the questionnaire. Of these, 509 patients belonged to the French Development sample-313 with dark skin (DS) (phototypes IV to VI) and 196 with fair skin (FS) (phototypes I to III). The US validation sample comprised 382 patients-113 DS and 269 FS. There was a very high correlation between VIPs-FS and its 12-item short-form, VIPs-12-FS, in both the development and validation samples (respectively, rho = 0.96, P < .0001 and rho = 0.98, P < .0001). Similarly, the correlations between VIPs-DS and its short-form, VIPs-12-DS, in both the development and validation samples were very high (respectively, rho = 0.95, P < .0001 and rho = 0.96, P < .0001). Limitations: Responsiveness of the 12-item short-forms should be confirmed. Conclusions: These data enabled the development and validation of 12-item short-forms of the VIPs questionnaires for fair (VIPs-12-FS) and dark (VIPs-12-DS) skin.
