We aimed to compare the effectiveness of 2 developmental tests-Korean Infant and Child Development Test (KICDT) and Korean Bayley Scale of Infant Development-II (K-BSID-II)-in the assessment of children with developmental delay.

Twenty-eight children with suspected developmental delay, who visited the Department of Pediatrics in Asan Medical Center from February 2007 to June 2008 were enrolled. They were examined using both KICDT and K-BSID-II. The results of the tests were compared on the basis of 2 parameters: age group of the children and detection of organic brain lesion on magnetic resonance imaging (MRI). The correlation between the results of the 2 tests was analyzed using SPSS. Further, intraclass correlation coefficient was calculated using SAS to examine consistency between the results of the 2 tests.

The mental developmental index of K-BSID-II showed significant correlation with every KICDT score ( P <0.01). The psychomotor developmental index of K-BSID-II was also significantly correlated with every KICDT score except the fine motor score ( P <0.01). The mental developmental index of K-BSID-II showed significant correlation [Editor20] with the KICDT gross motor, fine motor, and language scores ( P <0.05). Further, there was significant correlation between the psychomotor developmental index of K-BSID-II and the KICDT gross motor score ( P <0.05).

There was significant [Editor21]correlation between the results of KICDT and K-BSID-II for infants and children with developmental delay. Although our results suggest that KICDT is useful in assessing developmental delay, further research would be needed to standardize this test.
