Abstrakt:	Vitiligo has a major impact on health-related quality of life. Although a few vitiligo-specific quality of life instruments exist, there is no specific vitiligo burden tool. We developed and validated a specific vitiligo burden tool according to skin phototype. In total, 301 patients completed 35 items of the Vitiligo Impact Patient scale, of whom 235 were of skin phototype I to III and 66 of phototype IV to VI. The dimensionality of the items was evaluated using factor analyses, with results suggesting three factors in fair- and dark-skinned patients ("Psychological effects on daily life," "Relationships and Sexuality," and "Economic Constraints, Care & Management of Disease"). Unidimensionality was confirmed by higher order factor analysis. Cronbach's α were high-and intradimensional coherences all demonstrated good reliability (α > 0.8). The final instrument consists of 29 items (19 items common to all patients, 3 specific to fair skin, and 7 to dark skin). The test-retest reliability demonstrated very good reproducibility. The intraclass correlation of each dimension was greater than 0.90 for each population. External validity was confirmed by the correlation coefficients and Bland and Altman plots of the Vitiligo Impact Patient scale-Fair Skin and Vitiligo Impact Patient scale-Dark Skin versus the Short-Form-12, PVC Metra, Body Image States Scale, and Daily Life Quality Index assessment tools.
