This study investigates the infant's cognitive and motor development, mother's parenting knowledge, and father's participation of child-rearing according to demographic variables and child-care related variables. A total of 112 infants aged from 11.5 months to 12.5 months old were tested by Korean Bayley Scales of Infant Development II; in addition, their mothers participated in the survey. The major results were as follows: First, among five areas of parenting knowledge, mothers attained the highest score on socio-emotional development and the lowest on cognitive and language development. Second, fathers participation in child-rearing were related to their income and the time to start child-care center. Third, the development of infants were positively associated with the father's participation in child-rearing. The implications for designing child-care policy and parent education program were discussed.

Purpose: The purpose of this study was to trace the development of premature babies who had undergone neurodevelopmental treatment in the neonatal intensive care unit and to identify the effects of early neurodevelopmental treatment on the development of premature babies. Methods: Fifty-one premature babies, who had been hospitalized in the neonatal intensive care unit and received an infant motor performance test and Bayley scales-III evaluation of their developments during the six months of corrected age were included. They were divided into three groups: the intervention group (n=16), control group (n=23), and comparison group (n=12), depending on the risk of developmental delays and the existence of an intervention. The results of this study were analyzed using SPSS 22.0 for windows. The statistical significance level was set at ${\alpha}=0.05$. Results: Regarding the infant motor performance test scores for each group before the intervention, at two weeks after the start of intervention, and at post-conception of 40 weeks, the intervention group showed a significantly higher improvement than the control or comparison group (p<0.01). With respect to the Bayley scales-III at the corrected age of six months, the intervention group exhibited statistically significant differences from the control group in the domains of language and fine movements (p<0.01). Conclusion: The findings of this study could confirm that the early neurodevelopmental treatment of premature babies in the neonatal intensive care unit has continuous effects on the development of premature babies even after being discharged from the hospital.

Stability of the Korean Bayley Scale of Infant Development-II was tested in 305 infants by two measurements of varying intervals over a span of 5-36 months. Stability of K-BSID-II performance was r=.62(p<.01), r=.08(p<.18), r=.69(p<.01), r=.18(p<.01) for mental scale raw scores, mental scale index scores (MDI), psycho-motor scale raw scores and psycho-motor scale index scores(PDI), respectively. Stability was higher for the shorter test-retest interval group. Correlations between raw scores among infants with retest intervals of more than 2 years were stable on both mental and psycho-motor scales. MDI showed higher stability among high-risk infants than normal infants while PDI showed higher stability among normal infants. Testers and researchers should use both raw scores and index scores for better interpretations.

목 적 : 최근 신생아집중치료술의 발전으로 미숙아의 생존율이 증가하고 있다. 그러나 미숙아에서 저산소성 허혈성 손상의 주된 병변인 뇌실주위 백질연화증의 발생 위험성은 여전히 크며, 이는 뇌성마비 등의 심한 신경학적 합병증을 일으킬 수 있다는 점에서 임상적으로 지속적인 관심을 요하는 질환이다. 이에 본원에서 발생한 뇌실주위 백질연화증의 위험인자에 대하여 알아보고 뇌 자기공명영상 소견과 뇌초음파 분류에 따른 임상적 특징의 차이 및 예후에 대하여 알아보고자 이번 연구를 시행하였다. 방 법: 1999년 1월부터 2008년 12월까지 10년간 본원 신생아집중치료실에 입원한 36주 미만의 미숙아를 대상으로 하였고, 뇌 MRI나 뇌 초음파에서 뇌실주위 백질연화증소견을 보였던 25례를 환아군으로, 이들과 재태연령과 출생체중은 비슷하고 뇌실주위 백질연화증소견을 보이지 않았던 50례를 대조군으로 선정하여 두 군에서 뇌실주위 백질연화증의 위험인자로 예상되는 출산전, 주산기, 출산 후 요인과 Baley 발달 검사 결과 등을 후향적으로 비교 분석 하였다. 그리고 환아군에서 뇌MRI T2 강조 영상의 고신호 병변군과 저신호 병변군, 뇌초음파에서는 병변의 일측성, 양측성인 경우와 낭성, 비낭성 그리고, 국소성, 미만성을 구분하여 각각의 임상적 특징과 Baley 발달 검사 결과 등을 비교 분석하였다. 결 과:전체 374명의 대상 환자 중에서 뇌실주위 백질연화증이 25례(6.6%)에서 진단되었다. 환아군과 대조군의 비교에서 산모의 발열, 어린 산모의 나이, 장기간의 산소투여, 생후 1주 이내 발생한 저혈압, 생후 1주 이내 심수축제 사용과 호흡곤란 증후군이 뇌실주위 백질연화증 발생에 통계적으로 유의하게 관계가 있었다. 다중회귀 분석에서는 산모의 발열 및 장기간의 산소 투여가 독립적인 위험인자였다. Bayley 발달 검사 결과를 분석하였을 때 환아군은 정신 척도와 운동 척도가 각각 74.4$\pm$27.8과 58.0$\pm$17.7로 대조군의 103.5$\pm$8.9과 101.7$\pm$16.1 보다 통계적으로 의미있게 낮았다. 결 론 : 산모의 발열 및 장기간의 산소투여가 뇌실주위 백질연화증에 독립적으로 영향을 미치는 인자로 분석되었다. 그러므로, 이러한 위험 인자를 가진 미숙아들에 있어서 뇌 MRI 검사와 Bayley 발달 검사가 뇌실주위 백질연화증의 진단과 신경학적 합병증에 예후를 측정하는데 도움이 될 수 있다.

This study develops normative scores of the Infant/Toddler version of the Home Observation for Measurement of the Environment (IT-HOME) inventory for Korean infants and toddlers. We selected 482 0- to 36-month-old infants and families by a stratified sampling procedure that considered residency, age, and gender of children. The pass rate, discrimination rate, and internal consistency were analyzed for the item analysis. Statistical validity included intercorrelation among the IT-HOME subscales, correlation between IT-HOME scores and environmental status variables, and correlation between IT-HOME and Korean Bayley Scales of Infant Development second edition (K-BSID-II) scores. Normative scores were prepared by percentile ranks. The results of this study were as follows: First, 45 items were acceptable for Korean subjects with few exceptions. IT-HOME was developed to screen unfavorable environmental factors during infancy; therefore, items such as 12, 17, 23, 39, 44 need to be retained even though they had low discriminating power. Second, IT-HOME subscales were correlated, and IT-HOME was significantly related to parents' education level, household income level, and infant' developmental levels. Third, percentile scores and the median of each IT-HOME subscales were suggested as normative scores. We discussed the normative scores of the IT-HOME to screen the quality of home environments for children aged 0-36 months in Korea, and provide the intervention basis for the at-risk population.

Purpose: This study aimed to assess early development in very low birth weight (VLBW) infants with mild intraventricular hemorrhage (IVH) or those without IVH and to identify the perinatal morbidities affecting early neurodevelopmental outcome. Methods: Bayley Scales of Infant Development-II was used for assessing neurological development in 49 infants with a birth weight <1,500 g and with low grade IVH (${\leq}$grade II) or those without IVH at a corrected age of 12 months. Results: Among the 49 infants, 19 infants (38.8%) showed normal development and 14 (28.6%) showed abnormal mental and psychomotor development. Infants with abnormal mental development (n=14) were mostly male and had a longer hospitalization, a higher prevalence of patent ductus arteriosus (PDA) and bronchopulmonary dysplasia (BPD), and were under more frequent postnatal systemic steroid treatment compared with infants with normal mental development (n=35, P<0.05). Infants with abnormal psychomotor development (n=29) had a longer hospitalization and more associated PDA compared to infants with normal psychomotor development (n=20, P<0.05). Infants with abnormal mental and psychomotor development were mostly male and had a longer hospitalization and a higher prevalence of PDA and BPD compared to infants with normal mental and psychomotor development (n=19, P<0.05). Using multiple logistic regression analysis, a longer duration of hospitalization and male gender were found to be significant risk factors. Conclusion: Approximately 62% of VLBW infants with low grade IVH or those without IVH had impaired early development.

Purpose: This study examines changes in developmental profiles of children with language delay over time and the clinical significance of assessment conducted at age 2-3 years. Methods: We retrospectively reviewed the medical records of 70 children (62 male, 8 female), who had visited the hospital because of delayed language development at 2-3 years, and were reassessed at ages 5-6. Language and cognitive abilities were assessed using multiple scales at the initial and follow-up visits. Results: At the initial test, 62 of the 70 children had mental development index (MDI) below 70 of Bayley Scales of Infant Development Test II. Of the 62 children in the follow-up assessment, 30 children (48.4%) remained within the same cognitive range (full-scale intelligence quotient, FSIQ<70 of Wechsler preschool and primary scale of intelligence), 12 had borderline intellectual functioning (FSIQ, 70-85), 6 improved to average intellectual functioning (FSIQ>85), and 5 had specific language impairment, 9 had autism spectrum disorders. At the initial test, 38 of the 70 children had cognitive developmental quotients (C-DQ) below 70. Of the 38 children in the follow-up assessment, 23 children (60.5%) remained within the same cognitive range (FSIQ<70). The correlation coefficient for MDI and FSIQ was 0.530 (P<0.0001) and that for C-DQ and FSIQ was 0.727 (P<0.0001). There was a strong correlation between C-DQ and FSIQ, and a moderate correlation between MDI and FSIQ. Conclusion: Low MDI scores reflect a specific delay in cognitive abilities, communication skills, or both. The C-DQ, receptive language development quotient, and social maturity quotient also help to distinguish between children with isolated language delay and children with cooccurring cognitive impairment. Moreover, changes in the developmental profile during preschool years are not unusual in children with language delay. Follow-up reassessments prior to the start of school are required for a more accurate diagnosis and intervention.

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 (r=0.766, 0.739), while the gross and fine motor domains were highly correlated with Motor Age Quotient (r=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 (r=0.701, 0.770), as was the performance intelligence quotient with the fine motor domain (r=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.
