The Canadian Little Developmental Coordination Disorder Questionnaire (Little DCDQ-CA) is a parent-report screening instrument that identifies 3- to 4-year-old children who may be at risk for Developmental Coordination Disorder (DCD). We tested the factor structure and criterion validity of the Little DCDQ-CA in a sample of preschool-aged children in the United States ( = 233). Factor analysis indicated that the DCDQ-CA was best represented by one factor. Using cutoff scores that were proposed by the developer, 45% of the sample was identified as at-risk for DCD. Although a much larger percentage of children was identified as at-risk than would be expected based on the prevalence of formal DCD diagnoses in the population, the Little DCDQ-CA demonstrated good criterion validity. Specifically, compared with their peers, children who exceeded the at-risk criterion demonstrated worse motor competence, executive functioning skills, and early numeracy skills and were rated as having greater ADHD behaviors by their teachers, all consistent with expectations for children who are at risk for DCD. Results are discussed as they relate to future use of the Little DCDQ-CA.
加拿大儿童发育协调障碍问卷(Little DCDQ - CA)是一种由家长报告的筛查工具,用于识别可能有发育协调障碍(DCD)风险的3至4岁儿童。我们在美国学龄前儿童样本(n = 233)中测试了Little DCDQ - CA的因子结构和效标效度。因子分析表明,DCDQ - CA最好由一个因子来表示。使用开发者提出的临界分数,45%的样本被确定为有DCD风险。尽管被确定为有风险的儿童比例比根据该人群中正式DCD诊断的患病率预期的要高得多,但Little DCDQ - CA表现出良好的效标效度。具体而言,与同龄人相比,超过风险标准的儿童表现出更差的运动能力、执行功能技能和早期算术技能,并且教师对他们的多动症行为评分更高,所有这些都与对有DCD风险儿童的预期一致。讨论了这些结果与Little DCDQ - CA未来使用的相关性。
