Effectiveness Using of the Developmental Delay Screening Test in a Community, Korea

The purpose of this study is to examine the utility of developmental screening tests. I measured of developmental screening tests and compared with each test’s validity. This study was conducted to investigate their developmental delay by four developmental screening tests K-DIAL3, K-DDSTII, K-CDI and K-ASQ. When a child was included in the developmental delay class through a latent class analysis, probability of being detected as developmental delay child was 82%, 70%, 67% and 56% in K-DIAL3, K-ASQ, K-CDI and K-DDSTII respectively. Positive predictive values were 86%, 59%, 58% and 54% in K-DIAL3, K-ASQ, K-DDSTII and K-CDI respectively and those of combination of two of them were 95%~78% respectively. As Developmental delay positive rates of screening tests were high, more active measures such as exact diagnosis and appropriate management were needed and it was suggested that to improve efficacy of developmental screening tests of detecting developmental delay children two or more than one be used.
