발달문제 위험 아동 선별을 위한 한국형 Denver II 검사의 타당성에 관한 연구

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 x² 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.
