An effective population-based screening tool is needed to identify possible cases of Developmental Coordination Disorder (DCD) among preschool children in mainland China. We examined the psychometric properties of the DCD questionnaire’07 (DCDQ’07) in Chinese children aged 4–6. A total of 3316 children from 10 nursery schools were involved in the study. Internal consistency and test–retest reliability of the DCDQ’07 were estimated using Cronbach's alpha, item-total correlation and intraclass correlation co-efficient (ICC). The construct validity was evaluated using the exploratory and confirmatory factor analysis. Receiver operating characteristic (ROC) analysis was used to measure the accuracy of the DCDQ’07. The results showed that both internal consistency (Cronbach's alpha value of all items were above 0.85) and test–retest reliability (ICCs of 13 items and subscales were above 0.9) were excellent. Confirmatory factor analysis showed that each goodness-of-fit indices of the 3-factor model was above 0.9, indicating a satisfactory fit of the data to the model. Area under the ROC curve was comparatively small (0.641). With the exception of construct validity in younger children (4 years old) and discriminative validity, the Chinese version of the DCDQ’07 achieves satisfactory reliability and construct validity in mainland China. Nevertheless, the questionnaire should be not used in younger children, and further studies are needed to explore the use of Little DCD-Q in Chinese preschool children.
