AbstractThe Children's Dermatology Quality Index was developed as a tool to evaluate the quality-of-life in children with skin diseases. While a useful, self-administered scale, it has not been validated in Spanish for Mexican children. The aim of this study was to validate a Mexican version. Direct English-Spanish translation of the Children's Dermatology Quality Index was performed by two translators, and a single version was produced by a consensus of experts. Clarity was tested in a cohort of 60 healthy children. A reverse English-Spanish translation was performed. In a second stage, the quality-of-life was evaluated in a cohort of 64 pediatric patients with atopic dermatitis using the SCOring Atopic Dermatitis Index and COOP-Dartmouth questionnaires, and its severity evaluated with SCOring Atopic Dermatitis Index. Sixty-four patients (32 males), aged 11.8 +/- 2.9 years, with atopic dermatitis of 1 to 3 years of evolution were evaluated. The Mexican Spanish version of the Children's Dermatology Quality Index showed a high internal consistency (Cronbach's Alpha = 0.83; (CI(95%) = 0.76-0.88) and a high test-retest reliability (gamma(s) = 0.97, p < 0.001). A high correlation was observed between Children's Dermatology Quality Index and COOP-Dartmouth (gamma(s) = 0.97, p < 0.001) and moderate correlation with SCOring Atopic Dermatitis Index (gamma(s) = 0.53, p < 0.001). The Children's Dermatology Quality Index questionnaire in its Mexican Spanish version is valid and reliable for evaluating quality-of-life in Mexican pediatric patients with atopic dermatitis.
