[Creation and validation of the Ukrainian version of the Cardiff Acne Disability Index].

Original version of the Cardiff Acne Disability Index was translated into Ukrainian by two independent forward translators and then back-translated into English by two other independent translators. The probe technique for pre-testing was used. Retest reliability, discriminant and convergent validity and over time sensitivity were checked. The results of the Cardiff Acne Disability Index confirmed negative impact of acne on quality of life of Ukrainian patients.
