Difficulties in the performance of activities of daily living (ADL) are a key feature of developmental coordination disorder (DCD). The DCDDaily-Q was developed to address children's motor performance in a comprehensive range ADL The aim of this study was to investigate the psychometric properties of this parental questionnaire. Parents of 218 five to eight year-old children (DCD group: N = 25; reference group: N = 193) completed the research version of the new DCDDaily-Q and the Movement Assessment Battery for Children-2 (MABC2) Checklist and Developmental Coordination Disorder Questionnaire (DCDQ). Children were assessed with the MABC2 and DCDDaily. Item reduction analyses were performed and reliability (internal consistency and factor structure) and concurrent, discriminant, and incremental validity of the DCDDaily-Q were investigated. The final version of the DCDDaily-Q comprises 23 items that cover three underlying factors and shows good internal consistency (Cronbach's alpha > .80). Moderate correlations were found between the DCDDaily-Q and the other instruments used (p <.001 for the reference group; p > .05 for the DCD group). Discriminant validity of the DCDDaily-Q was good for DCDDaily-Q total scores (p <.001) and all 23 item scores (p <.01), indicating poorer performance in the DCD group. Sensitivity (88%) and specificity (92%) were good. The DCDDaily-Q better predicted DCD than currently used questionnaires (R-2 = .88). In conclusion, the DCDDaily-Q is a valid and reliable questionnaire to address children's ADL performance. (C) 2014 Elsevier Ltd. All rights reserved.
