PURPOSE
This study was done to evaluate the validity of the Korean - Child Development Review in screening children with developmental risks.
METHOD
The participants in the study were 172 children aged 6-75 months old and their parents. Data were collected by questionnaire or interview. Korean Denver II and Bayley test were administered with K-CDR for validation of children who were referred for developmental assessment at D University Hospital or public health center. The data were analyzed using correlation, chi-square test, and cross tab analysis.
RESULTS
There was a significant relationship between the K-CDR and Korean Denver II. The correlation coefficients were .42 to .61 by developmental sector. The sensitivity and specificity of K-CDR were .84 and .66 respectively when "abnormal" with MDI of Bayley test defined as lower than 85 the score which was used as a diagnosis of developmental delay. The responses to 6 questions for parents showed significant differences according to 3 groups by developmental state. Parents of children in the developmental disability group more frequently checked problems from the 26 problem checklist about their children's development and behavior.
CONCLUSION
The results show that K-CDR is valid and has good sensitivity and moderate specificity in screening developmental delay.

PURPOSE
This study was done to evaluate the validity of Korean Denver II developmental screening test in screening children with developmental risk. METHOD: The participants in the study were 113 children referred for developmental assessment in the department of rehabilitation of D University hospital. They were examined with the BSID (Bayley Scales of Infant Development) II and Korean Denver II by one occupational therapist. The data was analyzed by Chi square test and discriminant analysis. RESULTS: There was a significant relationship between the Mental Developmental Index (MDI) of the BSID II and the result of the Korean Denver II. The sensitivity and specificity of Korean Denver II were 0.87 and 0.62 when abnormal MDI was defined as lower than 85 was used as a diagnosis of developmental delay. There was a significant relationship between the Psychomotor Developmental Index (PDI) of the BSID II and the result of Korean Denver II. The sensitivity and specificity of Korean Denver II were 0.83 and 0.51. The over-all hit ratio was 79.6%. CONCLUSION: The result showed that the Korean Denver II was valid and has good sensitivity and moderate specificity in screening developmental delay.
