Insights
The Little Developmental Coordination Disorder Questionnaire-Taiwan (LDCDQ-TW) shows good reliability and validity for early identification of young children at risk of developmental coordination disorder (DCD) in Taiwan.
Area of Science:
- Pediatric developmental assessment
- Child psychology and development
- Motor skill disorders
Background:
- Early identification of developmental coordination disorder (DCD) is crucial for timely intervention.
- Preventing secondary sequelae associated with DCD requires effective screening tools.
- The Little Developmental Coordination Disorder Questionnaire (LDCDQ) is a parent-reported measure for DCD risk.
Purpose of the Study:
- To evaluate the psychometric properties of the Little Developmental Coordination Disorder Questionnaire-Taiwan (LDCDQ-TW).
- To establish the reliability and validity of the LDCDQ-TW for use in Taiwan.
- To determine the LDCDQ-TW's utility in identifying young children at risk for DCD.
Main Methods:
- A prospective study involving 1,124 parents of typically developing children (36-71 months) in Taiwan.
- The LDCDQ-TW, a 15-item parent questionnaire, and the Movement Assessment Battery for Children (MABC-2) were administered.
- Psychometric properties including test-retest reliability and concurrent validity were assessed.
Main Results:
- The LDCDQ-TW demonstrated excellent test-retest reliability (ICC = .97).
- Concurrent validity was supported, with LDCDQ-TW scores differentiating between DCD risk groups based on MABC-2.
- Sensitivity was .96 and specificity was .68 when using the 15th percentile cutoff.
Conclusions:
- The LDCDQ-TW is a reliable and valid tool for the early identification of children at risk for DCD in Taiwan.
- While not a diagnostic tool, the LDCDQ-TW supports early intervention efforts.
- Successful cross-cultural adaptation and validation of the LDCDQ-TW can improve outcomes for children with DCD.
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.
