Previous literature has shown inconsistency in the prevalence of developmental coordination disorder (DCD). The Movement Assessment Battery for Children, Second Edition (MABC-2) is often used for DCD prevalence studies, although the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) recommends four criteria.
The purpose of this study was to compare the prevalence of DCD in Korean children using the DSM-5 and MABC-2.
A total of 548 Korean elementary school students (mean age: 8.5 years ± 4.5 months) completed this study procedure. All four criteria defined by the DSM-5 were used to classify children with DCD. MABC-2 test scores were used to classify students into four subgroups: high-risk DCD, mild-risk DCD, probable DCD and typical development.
Cohen's kappa revealed that the estimates of DCD prevalence were not significantly different between MABC-2 and DSM-5. When DSM-5 criteria were applied, 60 children out of 548 were classified as probable DCD (10.94%) compared to 70 children with probable DCD (12.77%) when MABC-2 was used.
DCD prevalence based on DSM-5 is not significantly different from MABC-2, though it tends to estimate less than MABC-2. Future studies should consider our findings when selecting an assessment tool.
先前的文献表明，发育性协调障碍（DCD）的患病率存在不一致性。儿童运动评估电池第二版（MABC-2）常用于 DCD 患病率研究，尽管《精神障碍诊断与统计手册》第五版（DSM-5）建议使用四个标准。
本研究旨在使用 DSM-5 和 MABC-2 比较韩国儿童 DCD 的患病率。
共有 548 名韩国小学生（平均年龄：8.5 岁±4.5 个月）完成了本研究程序。使用 DSM-5 定义的所有四个标准来对患有 DCD 的儿童进行分类。MABC-2 测试分数用于将学生分为四个亚组：高风险 DCD、轻度风险 DCD、可能 DCD 和典型发育。
Cohen's kappa 表明，MABC-2 和 DSM-5 之间 DCD 患病率的估计值没有显著差异。当应用 DSM-5 标准时，548 名儿童中有 60 名被归类为可能 DCD（10.94%），而使用 MABC-2 时则有 70 名儿童被归类为可能 DCD（12.77%）。
基于 DSM-5 的 DCD 患病率与 MABC-2 没有显著差异，尽管它的估计值往往低于 MABC-2。未来的研究在选择评估工具时应考虑到我们的发现。
