The purposes of this study were to look at the patterns of Korean preschoolers' cortisol levels at home and to examine the relations of cortisol pattern to the preschooler's internalizing behavioral tendency with focused on behavioral inhibition and internalizing problematic behavior. The subjects of the study were forty 4-year old preschoolers(27 boys and 13 girls). Saliva was collected at home during the weekends, and cortisol was analyzed by Radioimmunoassay procedure. "Strange Peer Situation Experiment" developed by Rubin, Coplan, Fox and Calkins(1995) and revised by Rubin, Burgess and Hastings(2002) was used to measure the preschooler's behavior inhibition. Problematic behavior was measured through a "Korean Children's Behavior Checklist" (Oh, K. J., Lee, H. R., Hong, K. E., & Ha, E. H., 1997). The results were as follows: First, on average for a 4-year old, the level of cortisol was 0.22 in the morning, and 0.14 in the afternoon. There was a pattern that cortisol levels had declined in the afternoon. There was no difference in cortisol levels between genders. Secondly, there was a tendency that children of higher inhibition level at the lab showed the higher cortisol levels in the morning. However, this difference was not statistically significant. Thirdly, the higher the cortisol levels at home, the more showed internalizing behavior. Externalizing behavior was not correlated with the cortisol levels. It was concluded that cortisol may be related to children's internalizing behavior tendency.

Objectives : The aim of this study was to investigate correlation of childhood trauma experience and parent-adolescents' assessment reports on problem behavior through comparison of delinquent and general adolescents. Methods : First, delinquent adolescents and general adolescents were asked to complete the Childhood Trauma Questionnaire (CTQ). Then, 71 pairs of delinquent adolescents and their parents and 133 pairs of general adolescents and their parents were asked to complete the Korean Youth Self-Report (K-YSR) and the Korean Child Behavior Checklist (K-CBCL). Finally, responses from 410 people were used for the analysis. Results : First, childhood trauma experience score was significantly higher for delinquent adolescents, compared to general adolescents. Second, t-test showed a greater difference between K-YRS and K-CBCL for general adolescents than for delinquent adolescents. Third, in the case of delinquent adolescents, the correlation analysis of K-YSR filled out by adolescents and K-CBCL filled out by parents showed significant correlation in certain areas, including social immaturity, delinquent behaviors, internalization issues, and externalization issues. On the other hand, the correlation analysis of K-YSR and K-CBCL of general adolescents showed significant correlation in all sub-categories. Fourth, the correlation analysis of delinquent adolescents' CTQ and K-YSR showed minimal yet significant correlation in social adaptation, withdrawing, depression/anxiety, and delinquent/aggressive behaviors, however, no correlation was observed between CTQ and K-CBCL. The correlation analysis of general adolescents' CTQ and K-YSR, and CTQ and K-CBCL showed significant correlation in all sub-categories, although the degree of correlation varied. Conclusion : Delinquent adolescents had more childhood traumatic experiences. However, general adolescents' childhood traumatic experiences showed minimal yet significant correlation with various adaptation indicators and their parents responded in a similar way, indicating that general adolescents with childhood traumatic experiences need close care and attention even if they have not shown prominent delinquent behaviors.

Purpose: We investigated behavioral problems, attention problems, and cognitive function in children and adolescents born small for gestational age (SGA). Methods: Forty-six SGA children born at term and 46 appropriate for gestational age (AGA) children born at term were compared. Psychiatric symptoms were examined with reference to the Korean-Child Behavior Checklist, Korean-Youth Self Report, and Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS). Cognitive function was estimated using the Wechsler Intelligence Scale. Sociodemographic data were recorded from interviews. Results: SGA children had high scores on delinquent behavior, aggressive behavior, and the externalizing scale, and they also showed a propensity for anxiety and depression. The SGA group had a higher mean ADHD-RS score than the AGA group ($10.52{\pm}8.10$ vs.$9.93{\pm}7.23$), but the difference was not significant. The SGA group had a significantly lower verbal intelligence quotient (IQ) than the AGA group, but the mean scores of both groups were within normal limits. Conclusion: This study indicates marked behavioral problems, such as delinquency, aggressiveness, and anxiety and depression, as well as low verbal IQ in the SGA group than in the AGA group. Even in cases in which these symptoms are not severe, early detection and proper treatment can help these children adapt to society.

Objectives: This study aimed to evaluate the mental health status of the children of psychiatric patients in order to plan for the resources that may be necessary to help these children achieve their full potential. Methods: Forty-eight children (age 9-18) whose parents were registered in 5 community mental health centers located in Seoul were recruited. Tests assessing 3 psychological domains were conducted: 1) cognition: Korean version of Learning Disability Evaluation Scale, Comprehensive Attention Test, 2) parent reported emotion and behavior: Korean Child Behavior Checklist, Korean attention-deficit hyperactivity disorder Rating Scale, and 3) self-reported emotion and behavior: Korean Beck's Depression Inventory-II/Children's Depression Inventory-II, Korean Youth Self Report). We defined the children as having a high risk of developing mental health problems if their test scores were over the cut-off levels in 2 or more of the 3 domains assessed. Results: Twelve (25%) children were classified as having a high risk of developing mental health issues. 20 (41.6%) children scored above the cut-off in only one of the domains. Conclusion: Our results suggest that the children of psychiatric patients might be vulnerable to mental illness and need early prevention or interven-tions for the sake of their mental health.

Objectives: The aim of this study was to examine the association between current suicidal or violent behavior and deficits of specific neurocognitive variables in child and adolescent inpatient samples diagnosed with mood disorder. Methods: A retrospective review of the charts of mood disorder patients hospitalized at Samsung Medical Center between April 2004 and April 2015 was conducted. Child and adolescent patients aged between 10 and 18 years old and those who finished neurocognitive function testing during their hospitalization were included. Among them patients whose full scale IQ was between 85 and 115 were selected (N=111). Participants were first divided into two age-groups-group Y ($10{\leq}age{\leq}15$, N=54) and group O ($16{\leq}age{\leq}18$, N=57)-because neurocognitive function test tools were different according to age [Wechsler Intelligence Scale for Children (WISC) for 10 to 15-year-old patients, Wechsler Adult Intelligence Scale (WAIS) for 16 to 18-year-old patients]. They were then divided according to their suicidal or violent behavior-non suicidal/violent group (NG), suicidal group (SG), violent group (VG), and both suicidal/violent group (BG). The Child Behavior Checklist (CBCL) was checked for measurement of participants' behavior and the Gordon Diagnostic System was checked for measurement of their attention efficiency. Kruskal-Wallis Test and Tukey test was used to determine the differences in neurocognitive function between groups. Results: O-SG patients showed lower scores on the comprehension subscale of WAIS-III than O-NG patients (${\chi}^2=8.454$, p=.015). O-VG patients showed lower scores on the block design subscales of WAIS than O-SG patients (${\chi}^2=7.496$, p=.024). Y-VG patients showed higher scores in aggressive behavior, externalizing problems, and total problems scores of CBCL. Conclusion: This study showed relationship between specific neurocognitive deficits and suicidal or violent behavior. These relationships were significant in relatively older adolescents.

본 연구에서는 국내 학령기 아동을 대상으로 아동·청소년행동평가척도 조절곤란프로파일(Child Behavior Checklist Dysregulation Profile; CBCL-DP)의 요인구조를 조사하고, CBCL-DP특성을 보이는 집단(임상군)과 그렇지 않은 집단(정상군)간 부적응 및 문제행동 수준에 차이가 있는지 확인하고자 하였다. CBCL-DP의 가장 적합한 요인구조를 확인하기 위해 선행연구에서 제시한 3가지 경쟁모형에서 확인적 요인분석을 실시하였으며, 그 결과 단일요인모형(One-factor)과 2차요인모형(Second order)보다 Bifactor모형이 가장 좋은 적합도를 보였다. 가장 적합한 요인구조의 타당성을 확인하기 위해 관련 변인들과의 회귀경로를 계산한 결과 Bifactor모형에서 CBCL-DP는 부모가 보고한 집행기능곤란과 담임교사가 보고한 학교적응 및 강점난점의 모든 하위요인들과 관련되어 있었으며, 불안/우울, 공격행동, 주의집중문제의 3가지 요인들은 차별화된 연관성을 보였다. CBCL-DP의 특성을 나타내는 집단의 부적응 및 문제행동 수준을 CBCL-DP 특성을 보이지 않는 정상군과 비교한 결과, CBCL-DP 특성을 보이는 아동은 정상군 아동보다 집행기능 곤란 정도가 더 높았으며, 학교생활 적응을 잘 하지 못하고 바람직한 행동을 할 가능성이 낮은 것으로 나타났다. 결과적으로 CBCL-DP는 특정 증후군(AAA)보다 여러 가지 다양한 측면에서 부정적 결과와 관련이 있었으며, 선행연구들의 요인구조와 본 연구 표본이 부합하고 있다는 점은 광범위한 조절곤란 증후군으로 CBCL-DP를 개념화하는데 일관되고 통합적인 연구결과를 제시했음을 시사한다. 또한 CBCL-DP는 정서·행동문제가 결합된 고위험군 아동을 조기발견하고 중재함에 있어 학교 및 상담 장면에서 심층적이고 전문적인 진단도구로서 유용하게 사용될 수 있을 것으로 기대된다. 이러한 연구결과를 바탕으로 본 연구의 의의, 한계점 및 향후 연구 방향에 대해 논의하였다.

Objectives: In assessing behavioral/emotional problems in school-aged children, the importance of multi-informant reporting has been well documented. However, in clinical settings obtaining multiple informants' opinions has proven difficult. For that reason, we researched the agreement and predictive validity of the Child Problem-Behavior Screening Questionnaire (CPSQ) in order to reveal how accurate parents' assessments reflected teachers'opinions. Methods: We conducted the first screening for second- and third-grade children from 3 elementary schools in Seoul from 2003 to 2007 using the CPSQ. There were 1178 children included in the analysis. We then administered the Korean version of the Child Behavior Checklist (K-CBCL) as a second screening tool and subsequently, the ADHD Diagnostic System (ADS) and the Korean Educational Development Institute version of the Wechsler Intelligence Scale for Children (KEDI-WISC) was administered by a psychiatrist. We examined each item on the CPSQ and the subscale's agreement between parent and teacher as well as the predictive validity of the CPSQ in children diagnosed with emotional/behavioral problems. Results: The agreement rates between parents and teachers appeared high for questions 18 (0.433), 1 (0.385), and 2 (0.325). Among the subscales, a relatively high correlation was found for externalizing problems, attention deficit hyperactivity disorder, and cognitive problems. For all diagnosed children, their parents revealed a higher sensitivity and lower specificity than teachers. Conclusion: From these results, we confirmed that the CPSQ can be useful for sorting out externalizing and cognitive problems. There is a need for further study, however, with a larger sample size.

Objectives : Attention-deficit hyperactivity disorder (ADHD) and Asperger's disorder (AD) in children are associated with attentional problems, impulsivity, hyperactivity, and difficulties with social interactions. Pharmacological treatment may alleviate symptoms of ADHD, but seldom solves difficulties with social interactions. Social skills training (SST) may assist in improving their social interactions. We examined the effects of SST on children's social competences, general behavior, and ADHD symptoms. Methods : Thirty four children, aged 7 to 12 years, participated in the cognitive behavioral SST program once a week at the outpatient division of child-adolescent psychiatry. SST was composed of 24 sessions (ninety minutes) for 6 months. Twenty-five children were diagnosed with ADHD, and 9 children were diagnosed with AD. Parents of the children rated Korea-Child Behavior Checklist (K-CBCL), Conner's rating scales, Korean-ADHD Rating Scale (K-ARS), Social Skill Rating System (SSRS), and Matson's Social Skill Rating Scale as an evaluation of the treatment effect, before the first session and after the final session of the training. Results : The ADHD group showed significantly increased scores of social and social competence of CBCL and SSRS. Further, scores of externalizing problems of CBCL, CRS, and ARS were significantly decreased. The Asperger's group showed significantly increased scores of social competence of CBCL, SSRS, and MESS. There was a significant difference of the improvement in CBCL's school and total behavior problem score, CRS between drug change group and no drug change group. Conclusion : The result of this study suggests that SST is effective in improving social skills for children with ADHD and AD. In addition, SST has shown its effectiveness in treating attentional problems for children with ADHD. To prove objective usefulness of SST, further studies with a more structured design and long-term duration along with a sufficient number of AD participants will be necessary.

This study examined the relationships between parenting styles, academic achievement, and behavioral adjustment of adolescents in Korea. Using a sample of 181 parents and their children (13-15 years old), parents completed the Parental Authority Questionnaire and adolescents filled out the Youth Behavior Checklist (CBCL) and provided their school grades. Factor analysis was conducted on the PAQ to confirm the psychometric properties. Hierarchical regression analysis was computed to determine the relationship between maternal and paternal parenting styles, academic performance, and children's internalizing and externalizing behaviors. Regression analysis revealed that mother's authoritative parenting style was positively related with adolescents' grades in English. However, father's permissive was negatively related with adolescents' grades in English, Mathematics, and Science. Mother's permissive parenting styles showed negative effects of internalizing and externalizing behavior problems whereas father's permissive parenting styles showed positive effects of internalizing and externalizing behavior problems.

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, $X^2$ 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.
