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 (N = 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.

加拿大小发育协调障碍问卷 (Little DCDQ-CA) 是一种家长报告筛查工具，用于识别可能处于发育协调障碍 (DCD) 风险中的 3 至 4 岁儿童。我们在美国学龄前儿童样本中检验了 Little DCDQ-CA 的因子结构和效标效度（N= 233)。因子分析表明 DCDQ-CA 最好用一个因子表示。使用开发人员提出的截止分数，45% 的样本被确定为存在 DCD 风险。尽管根据人群中正式 DCD 诊断的流行率，确定有风险的儿童比例要高得多，但 Little DCDQ-CA 显示出良好的标准效度。具体来说，与同龄人相比，超过高危标准的儿童表现出更差的运动能力、执行功能技能和早期计算能力，并且被老师评为有更多的多动症行为，所有这些都符合对高危儿童的期望为 DCD。讨论结果，因为它们与 Little DCDQ-CA 的未来使用有关。
