Validation of a Mexican Spanish Version of the Children’s Dermatology Life Quality Index

Abstract: The 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 (γ_s = 0.97, p < 0.001). A high correlation was observed between Children’s Dermatology Quality Index and COOP‐Dartmouth (γ_s = 0.97, p < 0.001) and moderate correlation with SCOring Atopic Dermatitis Index (γ_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.
