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 (Créteil 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.

简短形式的白癜风影响患者量表（VIP）的跨文化验证。

背景技术缺乏根据皮肤照相类型评估白癜风负担的简短形式的问卷。目的开发并验证考虑到皮肤照相类型的12个项目的白癜风影响患者量表（VIP）的简短形式。方法在法国（克雷泰伊和波尔多）和美国（马萨诸塞州伍斯特和德克萨斯州达拉斯）进行的多中心，前瞻性，横断面研究。结果共有891例患者完成了问卷。其中，509名患者属于法国发展样本313，皮肤深色（DS）（IV型至VI型），196名皮肤白皙（FS）（I型至III型）。美国验证样本包括382名患者-113 DS和269 FS。在开发和验证样本中，VIPS-FS与它的12个项目的简短形式VIPs-12-FS之间的相关性非常高（分别是，rho = 0.96，P <.0001，rho = 0.98，P <.0001）。同样，在开发和验证样本中，VIPs-DS及其简短形式VIPs-12-DS之间的相关性都非常高（分别为rho = 0.95，P <.0001和rho = 0.96，P <.0001 ）。局限性应该确认12个项目的简短形式的响应能力。结论这些数据使得能够开发和验证针对白皙（VIPs-12-FS）和深色（VIPs-12-DS）皮肤的VIP问卷的12种简短形式。
