Cross-cultural Adaptation, Psychometric Validation and Reference Norms for the European Spanish DCD-Questionnaire University Universidade da Coruña Year of defence 2021 Keywords activities of daily living, motor skills disorders, surveys and questionnaires, cross-cultural comparison, child, and motor skills Summary in Spanish Developmental Coordination Disorder (DCD) affects 5-6% of school-aged children. Still, DCD is a highly underdiagnosed disorder in the Spanish context. Providing cross-culturally adapted, reliable and accessible diagnostic instruments is a necessary first step to improve the quickly identification of children at risk of DCD and to raise awareness of this disorder in the Spanish context. The aims of this thesis were (1) to translate and cross-culturally adapt the Developmental Coordination Disorder Questionnaire (DCDQ) into European Spanish, (2) to test its psychometric properties in the Spanish population, and (3) to develop country-adjusted reference norms of the DCDQ for Spanish children. The DCDQ was cross-culturally adapted into European Spanish following international guidelines (DCDQ-ES), and it was standardized using a sample of 570 Spanish children. After a multi-step process involving a multidisciplinary team, the DCDQ-ES achieved good cross-cultural equivalence. Internal consistency values were excellent, and construct, concurrent and discriminant validity of the DCDQ-ES were adequate. Finally, age-specific reference norms were developed for Spanish children. In conclusion, the DCDQ-ES shows cross-cultural equivalence with the original version, and it shows good psychometric properties in the Spanish context. The DDCDQ-ES is a reliable and valid instrument to assist in the quick identification of DCD in Spanish children. Summary in English
