Background:
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.
Aims:
The purpose of this study was to compare the prevalence of DCD in Korean children using the DSM-5 and MABC-2.
Methods:
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.
Results:
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.
Conclusions:
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.

05:44Metacognitive Development: How Children Estimate Their Memory
Human memory is fallible, and people often cannot accurately recall what they have seen or heard. Adults are aware of their limited memory capacity, so they use strategies, such as rehearsal and mnemonic devices, to improve their recall of important information. Because adults understand the limits of memory, they know it makes more sense to write down the items on their shopping list rather than to try...
