Abstract:
Background: Most developmental screening tools in Korea are adopted from foreign tests. To ensure efficient screening of infants and children in Korea, a nationwide screening tool with high reliability and validity is needed.Purpose: This study aimed to independently develop, standardize, and validate the Korean Developmental Screening Test for Infants and Children (K-DST) for screening infants and children for neurodevelopmental disorders in Korea.Methods: The standardization and validation conducted in 2012–2014 of 3,284 subjects (4–71 months of age) resulted in the first edition of the K-DST. The restandardization and revalidation performed in 2015–2016 of 3.06 million attendees of the National Health Screening Program for Infants and Children resulted in the revised K-DST. We analyzed inter-item consistency and test-retest reliability for the reliability analysis. Regarding the validation of K-DST, we examined the construct validity, sensitivity and specificity, receiver operating characteristic curve analysis, and a criterion-related validity analysis.Results: We ultimately selected 8 questions in 6 developmental domains. For most age groups and each domain, internal consistency was 0.73–0.93 and test-retest reliability was 0.77–0.88. The revised K-DST had high discriminatory ability with a sensitivity of 0.833 and specificity of 0.979. The test supported construct validity by distinguishing between normal and neurodevelopmentally delayed groups. The language and cognition domain of the revised K-DST was highly correlated with the K-Bayley Scales of Infant Development-II’s Mental Age Quotient ( 〈 i 〉 r 〈 /i 〉 =0.766, 0.739), while the gross and fine motor domains were highly correlated with Motor Age Quotient ( 〈 i 〉 r 〈 /i 〉 =0.695, 0.668), respectively. The Verbal Intelligence Quotient of Korean Wechsler Preschool and Primary Scales of Intelligence was highly correlated with the K-DST cognition and language domains ( 〈 i 〉 r 〈 /i 〉 =0.701, 0.770), as was the performance intelligence quotient with the fine motor domain ( 〈 i 〉 r 〈 /i 〉 =0.700).Conclusion: The K-DST is reliable and valid, suggesting its good potential as an effective screening tool for infants and children with neurodevelopmental disorders in Korea.
