This study was designed to explore developmental evaluation in healthy full-term, at risk preterm and full-term infants. Specifically the purposes of the study were to investigate Psychomotor Developmental Index(PDI) and Mental Developmental Index(MDI) based on Bayley Scales of Infant Development(1993). The subjects were 72 infants, 24 each for healthy full-term infants, 24 each for at risk preterm infants and 24 each for at risk full-term infants such as having neonatal asphyxia, hypoxic ischemic brain damage, respiratory distress syndrome. The data were analyzed through Kruskal-Wallis test and correlations to examine healthy full-term, at risk pre-term and at risk full-term infants. Results showed that there were significant differences among healthy full-term, at risk pre-term and at risk full-term infants in PDI and MDI. On the correlation with PDI and MDI, infants showed significant correlations. Early interventions for developmental improvement are required for functional outcome in these infants.

This study examined risk and protective variables related with the continuity of developmental risks among 136 infants, aged 4-10 months. Using the Denver Developmental Screening Test, 136 infants among 2978 infants in the first wave of the Korea Child Panel were classified into the developmental risk group. Among the 136 risk group infants, 45 infants stayed in the risk group (continuing risk group) and the other 91 infants moved into the normal group (recovering risk group) after 1 year. Group differences were tested in the levels of infant, mother and father variables to examine which variables were associated with the continuity of developmental risks for a year. Variables indicating parents' marital relationships such as the mothers' marital satisfaction and conflict of the first wave and the fathers' marital satisfaction of the second wave significantly distinguished the continuing from the recovering risk group. In addition, there were significant group differences in the levels of mothers' self-efficacy in the first wave. The findings suggest that the exposure to marital conflict during infancy is associated with the continuity of developmental risks.

Objectives: This study aims to examine the positive effects of developmental assets on the prevention of health risk behaviors among Korean adolescents. The framework of developmental assets was introduced as building blocks for healthy child and adolescent development by Benson and his colleagues. These assets represent positive external environmental factors and internal personal qualities which strongly influence the quality of life of adolescents. Methods: In 2001, we administered self-reported questionnaires to 3,739 girls and boys in grade 9 at eight schools in two cities, Chinju and Suwon in South Korea. The data was compiled into a 'Korean Youth Health Related Behaviors and Developmental Assets Survey' and then analyzed Youth health risk behaviors, which we measured in terms of their frequency, included tobacco, alcohol, and substance use, sexual intercourse, anti-social behaviors, violence, feelings of social isolation at school, depression or attempted suicide, absenteeism from school, gambling. Results: Overall, with respect to developmental assets, the Korean adolescents surveyed only 12.6 of the 40 assets, and 88 percent of adolescents had 20 or fewer of the assets. Based on their number of developmental assets(DA), adolescents were categorized into four groups: Group I(DA 0-10): Group II(DA 11-20): Group III(DA 21-30): Group IV(DA 31-40). We examined the differences in the frequency of each health risk behavior across the four groups, Group I-IV, and found that the frequency of most health risk behaviors decreased as the number of developmental assets increased. Conclusion: We therefore concluded that in order to make effective approaches for the prevention of health risk behaviors among adolescents, we should consider and develop more comprehensive and adolescents-based policy and programs to promote various aspects of adolescents' health and quality of life.

Purpose: This study was conducted to estimate the prevalence of questionable development according to developmental screening testing for children, and to explore biological and environmental risk factors of developmental delays. Method: The study participants were 153 children under two years of age. A questionnaire and Home Observation for measurement of the Environment (HOME) inventory were used to collect data, and Korean Denver II was administered. Results: The overall prevalence of questionable development was 11.1%. Significant differences in biological factors between the normal development group and questionable development group were the rate of prematurity, twins, the educational level of mother and father's and the presence of an illness in the mother (p<.10). Maternal acceptance in HOME was significantly different between the two groups. The factors related to questionable development that were significant in the logistic regression analysis were prematurity (OR=3.56, p=.026), and maternal acceptance in HOME score (OR=.629, p=.028). Conclusion: Early developmental screening tests seem necessary for all children, especially for prematurely born children. Also, child rearing environments were identified as significant factors in the development of all children. These findings suggest that the HOME scores might be useful in identifying children at risk for developmental delays, and that interventions for these children will probably be more effective if their mothers are helped to provide a more appropriate social environment.

The purposes of the study is to examine the relationship between developmental assets, stress and risk behaviors of university students. The subject of the study is 1023 university students. Questionnaire organized by scales of developmental assets, stress and risk behaviors was used. The major findings were as follows; First, internal assets made direct effects on stress and risk behaviors. External assets made direct effects on stress. Second, mediating effects of stress were statistically significant in relations between developmental assets and risk behaviors. External assets were complete mediating effects by making effects indirectly on risk behaviors through the stress. Internal assets showed partial mediating effects.

The purpose of this study was to employ the Latent Growth Curve Model to investigate the developmental trajectories of maternal depressive symptoms and to identify predictors that might have an effect on change and the level of developmental trajectories. The results of this study indicated that the maternal depressive levels of a high risk group had increased significantly over the past 5 years. The predictors for these developmental trajectories of maternal depressive symptoms were as follows; birth order, maternal prenatal depressive levels, self-esteem, marital satisfaction, parenting stress and the level of family crisis experienced by the high risk group.

Objectives : The purpose of this study was to examine the prenatal, perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD), compared to unaffected siblings (SIB), and typically developing children (TC). Methods : Subjects with ADHD, their SIB, and TC were recruited from the child psychiatry outpatient clinic of the Asan Medical Center Children's Hospital. The parents of the children completed questionnaires on perinatal and developmental risk factors. Results : Fifty-eight subjects with ADHD (41 boys, $7.7{\pm}1.3years$), 21 SIB (8 boys, $8.2{\pm}1.8years$), and 22 TC (8 boys, $8.5{\pm}2.1years$) were included. The ADHD group showed higher rates of maternal stress during pregnancy than the SIB group (p=.002), and the ADHD group showed higher rates of familial psychiatric history than the TC (odds ratio, 8.76 ; 95% confidence interval, 1.69 to 45.45). Conclusion : These findings suggest that among perinatal and developmental factors, maternal stress during pregnancy contribute to the development of ADHD. Future prospective studies will be needed in order to determine the causal relationship between perinatal risk factors and development of ADHD.

Objectives:The objective of this study was to examine the perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD) diagnosed with a structured interview among Korean children. Methods:The current study included 924 children (6-15 years) recruited from schools in five Korean cities or a child psychiatry outpatient clinic of Seoul National University Children's Hospital. The parents of the children completed the structured diagnostic interview for attention-deficit hyperactivity disorder, as well as questionnaires on perinatal and developmental risk factors. Results:Preterm delivery, severe maternal stress during pregnancy, change in primary care taker during the first three years, postpartum depression, and delayed first sentence showed a significant association with ADHD diagnosis. Conclusion:These findings suggest that perinatal and developmental factors contribute to development of ADHD in Korean children. Conduct of future research using a prospective design is needed in order to identify the causal relationship between observed risk factors and development of ADHD.

Purpose: Developmental disabilities (DDs) are a global childhood problem whose prevalence is rising, with a disproportionate impact on individuals in low-and middle-income countries. However, data on the prevalence of DDs in the Arab world are limited. This review highlights what is currently known about the prevalence and risk factors of DDs in preschool children in the Arab world. Methods: PubMed, Cochrane Library, Scopus, CINAHL, Science Direct, and Google Scholar were searched for publications on DDs among preschool children in the Arab world. Only 14 studies were identified in the literature, from 12 Arab countries. Results: The overall estimated prevalence of DDs among preschool children in the Arab world is 27.5%. An analysis of risk factors for DDs showed that child-related, maternal, and family-related factors account for a significant cumulative risk of developing DDs in preschool children. Maternal factors, such as antenatal and perinatal complications, were the most common risk factors. Conclusion: The prevalence of DDs among preschoolers is significantly high in the Arab world, which emphasizes the importance of the early detection and diagnosis of DD, as well as its associated risk factors.

Purpose: This study was done to evaluate the validity of Korean Denver ll 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 $x^2$ 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 ll and the result 0.7 Korean Denver ll. 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.
