Psychometric Properties of the Little Developmental Coordination Disorder Questionnaire–Taiwan.

Importance: Early identification of young children at risk of developmental coordination disorder (DCD) can support early intervention and prevent secondary sequelae. Objective: To examine the psychometric properties of a translated and cross-culturally adapted version of the Little Developmental Coordination Disorder Questionnaire–Taiwan (LDCDQ–TW). Design: Prospective study. Setting: Kindergartens and preschools in north, central, and south Taiwan. Participants: In Phase 1 the participants were 1,124 parents of typically developing children ages 36–71 mo. Children with confirmed developmental diagnoses were excluded. Participants in Phase 3 were 162 children who had been recruited in Phase 2. Outcomes and Measures: The LDCDQ–TW, a 15-item parent questionnaire for identifying children at risk for DCD, and the Movement Assessment Battery for Children (2nd ed.; MABC–2), were administered. Results: The findings revealed excellent test–retest reliability (intraclass correlation coefficient [ICC] =.97) and poor interrater reliability (ICC =.47). On the basis of MABC–2 scores, the non-DCD group (≥15th percentile) scored significantly higher than the DCD and suspect-DCD groups on the LDCDQ–TW, but the latter two groups did not differ from one another. Using the 15th percentile as a cutoff for both the MABC–2 and the LDCDQ–TW, sensitivity was.96 and specificity was.68. Conclusions and Relevance: Although standardized performance-based assessments are required to confirm a diagnosis of DCD (typically after age 5 yr), the LDCDQ–TW demonstrated sound reliability and validity and can support the early identification of young children at risk of DCD in Taiwan. What This Article Adds: The LDCDQ–TW can facilitate early intervention for DCD and prevent secondary sequelae, improving outcomes for children with DCD. The LDCDQ–TW demonstrated sound reliability and validity and can support the early identification of young children at risk of developmental coordination disorder in Taiwan. [ABSTRACT FROM AUTHOR]
