Abstract

Background: The Developmental Coordination Disorder Daily Questionnaire (DCDDailyQ) was developed as an instrument for identification of children with Developmental Coordination Disorder (DCD). With this parental questionnaire, differences in performance of activities of daily living (ADL) between children with DCD and typically developing {TD) children can be measured. Aim: To examine the psychometric properties of the DCDDailyQ including its relevance as an instrument for identification of children with DCD. Methods: 58 children, 5 to 8 years old, participated in this pilot study. It was investigated whether the DCDDailyQ discriminates between ADL performance of children with DCD and TD children. Internal consistency was determined to examine whether the 35 items measure the same construct. Factor analysis were performed to investigate the structure of the DCDDailyQ. Concurrent validity was examined by comparing the DCDDailyQ scores to the Movement Assessment Battery for Children 2 (Movement ABC-2), the Checklist of the Movement ABC-2 and the Developmental Coordination Disorders Questionnaire (DCDQ). Finally, specificity and sensitivity of the DCDDailyQ were determined. Results: The DCDDailyQ discriminates between children with DCD and TD children. Internal consistency was high (0.91), indicating that the items of the DCDDailyQ measure the same construct. It was not possible to make a proper classification of factors and items loading on these factors. Significant correlations between DCDDailyQ scores and other instruments support concurrent validity. A high specificity value was found, although the sensitivity was slightly too low. Conclusion: Results of this pilot study show that the DCDDailyQ meet standards for reliability and most aspects of validity, although it needs more development before it can be used in practice.
