Background: The Cardiff Acne Disability Index (CADI) is a specific tool for measuring the impact on the quality of life of patients with acne, and has been translated and validated into multiple languages. Objective: We present the definitive Uruguayan Spanish version of the CADI questionnaire, and its validation process. Material and methods: The translation from its original version in English was carried out following international recommendations, including translation by several professionals, a back-translation into English, and a subsequent comprehensibility test carried out on individuals with acne. Then an observational, prospective, and multicenter validation study was conducted, including 54 individuals with acne who completed the questionnaire twice within a 14-day interval. Results: The cross-cultural translation and adaptation process identified, and resolved compatibility difficulties. Likewise, its clarity and understandability were demonstrated. The questionnaire showed good internal consistency, with a Cronbach’s alpha coefficient of 0.81, and good test-retest reliability, with a Pearson coefficient of 0.86, and an intraclass correlation coefficient of 0.84. Conclusions: The CADI, a valuable tool for assessing the impact of acne on our patients, is available to be used in Uruguay.
