Summary Background and Objectives Skin diseases can greatly impair quality of life (QoL) of pediatric patients and their families. The Infants and Toddlers Dermatology Quality of Life questionnaire (InToDermQoL) is the first skin‐generic instrument assessing QoL in children ≤ 4 years, as reported by their caregiver. This study aimed to psychometrically validate the German version of the InToDermQoL. Patients and Methods The psychometric properties of the InToDermQoL were examined in a sample of 148 children with various skin diseases (age groups n: < 1 44; 1–2 68; 3–4 36). Results Exploratory factor analysis suggested a unidimensional structure of the version for children < 1 year, and a two‐ and three‐factor structure for the two older age groups, respectively. Internal consistency was excellent (Cronbach's alpha, 0.904–0.922). Two‐week test–retest reliability was good, except in children aged 1–2 years (intraclass correlation coefficient ICC, 0.430). The InToDermQoL demonstrated good convergent validity with other QoL questionnaires. Conclusions The German InToDermQoL is a valid and reliable QoL measure in children ≤ 4 years with any skin disease. Application of the tool in research and clinical practice will contribute to a better understanding of the impact of pediatric dermatoses, and optimize care and support for affected families.
