This project corresponds to the data generated throughout the translation, cultural adaptation, and validation process of 'The Developmental Coordination Disorder Questionnaire' to European Portuguese from English. This questionnaire was developed to collect parents' perceptions of motor coordination performance in children aged between 5 and 15 years old. It is intended to be completed by parents or caregivers and can be utilized in educational, clinical, therapeutic, or research contexts. The data will be presented in three different parts, each corresponding to a specific phase: translation process, pilot study, and validation. The methodological steps followed are those recommended by Brenda Wilson, the author of the original questionnaire, who has provided written authorization for this research project.
