Background: vitiligo,although asymptomatic,highly compromises patients´ quality of life (qol). therefore,an adequate evaluation of qol is essential. objectives: translation,cultural adaptation and validation of vitiqol (vitiligo-specifi c health-related quality of life instrument) into brazilian portuguese. methods: the study was conducted in two stages; the fi rst stage was the translation and cultural/linguistic adaptation of the instrument; the second stage was the instrument´s validation. results: the translated vitiqol showed high internal consistency (cronbach alpha = 0.944) and high test-retest reliability and intraclass correlation coeffi cient=0.95 (ci 95% 0.86 - 0.98),p<0.001. there was no statistically sig-nifi cant difference between the means of the fi rst completion of the vitiqol questionnaire and the retest,p = 0.661. there was a signifi cant correlation between vitiqol and dlqi (r = 0.776,p <0.001) and also between vitiqol-pb and subjects’ assessment of the severity of their disease (r = 0.702,p <0.001). conclusions: the impact of vitiligo on the qol of brazilian patients can be assessed by a specific questionnaire. © 2015,by anais brasileiros de dermatologia.
