| Abstract: | BackgroundEarly recognition of children at risk of Developmental Coordination Disorder (DCD) is important, but variability in motor development in preschool children affects the validity of instruments to reliably detect children at risk of DCD.AimsTo investigate the age-related validity and reliability of the Dutch version of the Little Developmental Coordination Disorder Questionnaire (LDCDQ-NL).Methods and proceduresTwo hundred and sixty 3- to 5-year old children were recruited in the Netherlands. Parents filled out the LDCDQ-NL and children were assessed with the Movement Assessment Battery for Children-2 Test (MABC-2 Test). Internal consistency of the LDCDQ-NL was determined by Cronbach’s alpha. Construct validity was investigated using factor analysis. Concurrent validity was measured by calculating correlations between the LDCDQ-NL and MABC-2. Receiver Operating Characteristics (ROC) were calculated to assess discriminant validity.Outcomes and resultsInternal consistency of the LDCDQ-NL was 0.91. Factor analysis resulted in three factors (Fine motor skills, Locomotor skills, Ball skills). Correlation between the LDCDQ-NL and MABC-2 Test increased with increasing age. With a sensitivity of 80%, specificity increased with age.Conclusions and implicationsThe LDCDQ-NL is a reliable and valid screening instrument for 4- and 5-year old Dutch children; concurrent and discriminant validity are low for 3-year olds. |
