Evaluation of the degree of adherence to self-care among Spanish type 1 diabetes (T1DM) pediatric population lacks of a validated tool. To cross-culturally adapt and determine the psychometric properties of the Spanish version of the Diabetes Management Questionnaire to assess the degree of adherence to self-care among children with T1DM. Translation, back-translation, and patient suggestions, were considered to obtain the Spanish version (DMQ-Sp). A cross-sectional study was conducted with 323 children (aged 8–18 years) with T1DM and their parents to determine internal reliability, structural validity, and external validity. Responsiveness to change was analyzed through a prospective longitudinal study involving 102 newly diagnosed T1DM patients. Psychometrics were evaluated for the entire sample and stratified by age (8–12 and 13–18 years). A total of 323 children with T1DM [49.8% female; age 13.3 ± 2.8 years; 155 aged 8–12; glycated hemoglobin (HbA1c) value 7.7 ± 1.0%] answered the Spanish final version. The internal consistency Cronbach's alpha was 0.76 and intraclass correlation coefficient 0.84. Test-retest reliability was r = 0.84 (p 0.7. External validity correlated inversely with HbA1c (r = −0.39; p
