Early 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.
To investigate the age-related validity and reliability of the Dutch version of the Little Developmental Coordination Disorder Questionnaire (LDCDQ-NL).
Two 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.
Internal 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.
The 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.
早期识别发育性协调障碍（DCD）风险儿童很重要，但学龄前儿童运动发育的变异性会影响可靠检测 DCD 风险儿童的工具的有效性。
研究荷兰语版发育性协调障碍问卷（LDCDQ-NL）的年龄相关性有效性和可靠性。
在荷兰招募了 260 名 3 至 5 岁的儿童。家长填写 LDCDQ-NL，儿童接受儿童运动评估测试-2 版（MABC-2 Test）评估。LDCDQ-NL 的内部一致性通过 Cronbach's alpha 确定。通过因子分析研究结构有效性。通过计算 LDCDQ-NL 与 MABC-2 之间的相关性来测量同时效度。计算接收者操作特征（ROC）以评估判别有效性。
LDCDQ-NL 的内部一致性为 0.91。因子分析产生了三个因素（精细运动技能、移动技能、球技）。LDCDQ-NL 与 MABC-2 测试之间的相关性随年龄的增加而增加。敏感性为 80%，特异性随年龄增加而增加。
LDCDQ-NL 是一种可靠且有效的 4 至 5 岁荷兰儿童筛查工具；3 岁儿童的同时和判别有效性较低。
