Objectives:We analyzed the usefulness of intelligence test in assessing attention-deficit hyperactivity disorder (ADHD). Methods:The medical records of 312 patients with ADHD who visited the child psychiatry department in one university hospital in Seoul, Korea, were reviewed. Demographic data and scores on the Korean Wechsler Intelligence Scale for Children-III (K-WISC-III) and Korean-Conners' Parent Rating Scale (K-CPRS) were analyzed. To assess the relationship with comorbidities, AD-HD subjects were classified as; externalizing disorders, internalizing disorders, tic disorders, and no comorbidities. Results:Verbal intelligence quotient (VIQ) was significantly higher than performance IQ (PIQ)($102.6{\pm}14.44$, $99.2{\pm}14.48$, p<.001). Using mean scatter method, subtest scores such as 'information, similarities, digit span and coding' were significantly lower than mean scores of sum of subtests of VIQ or PIQ (p<.05). Regarding comorbidities, children with externalizing disorders exhibited. Lower scores on 'information and vocabulary' than other groups (p=.008). Children with no comorbidities exhibited higher scores on 'similarities and object assembly' than children with externalizing/internalizing disorders (p=.001) and also on 'comprehension' than children with externalizing disorders (p=.006). For subtypes of ADHD, children with hyperactive-impulsive type had higher scores on 'comprehension' than children with inattentive and combined type (p=.004). Conclusion:These results suggested that intelligence test might provide useful information for assessing ADHD.

Objectives: The purpose of this study was to verify the validity and clinical cutoff score of the Child Behavior Checklist for ages 1.5-5 (CBCL 1.5-5) for diagnosis of autism spectrum disorder (ASD). Methods: 44 ASD infants and 100 normal infants participated. T-test, discriminant analysis, receiver operating characteristic (ROC) curve analysis, and odds ratio analysis were performed on the data. Results: Discriminant validity was confirmed by mean differences and discriminant analysis on the subscales of Withdrawn, Attention problems, Internalizing problems, Externalizing problems, Total problems, and all Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales between the two groups. ROC curve analysis showed that Withdrawn, Attention problems, Internalizing problems, Externalizing problems, Total problems, DSM pervasive developmental problems, DSM attention deficit/hyperactivity problems, and DSM oppositional defiant problems significantly predicted ASD infants compared to normal infants. In addition, the clinical cutoff score criteria adopted in the Korean CBCL 1.5-5 for subscales of Withdrawn, Attention problems, Internalizing problems, Externalizing problems, Total problems, DSM pervasive developmental problems, DSM attention deficit/hyperactivity problems, and DSM oppositional defiant problems were shown to be valid. Conclusion: The subscales of Withdrawn, Attention problems, Internalizing problems, Externalizing problems, Total problems, DSM pervasive developmental problems, DSM attention deficit/hyperactivity problems, and DSM oppositional defiant problems significantly discriminated for the diagnosis of ASD.

The purpose of this study was to compare the difference between the adaptive and internalizing/externalizing maladaptive behaviors of the sensory processing problemtic group classified from non-disabled preschoolers and to confirms the effects of sensory processing sub-factors on adaptive and maladaptive behaviors. This study participated in 335, 3-6 years typical preschoolers, carried out Short sensory profile, Vineland-II adaptive behavior scales. The study result in the sensory processing showed a significant positive correlation with the adaptive behavior, and a significant negative correlations were found in the internalizing/externalizing maladaptive behaviors. In the t-test, the problemtic group had lower adaptive behavior scores than the typical group. This study confirmed that atypical sensory processing affected not only adaptive behavior, but also internalizing/externalizing maladaptive problems, that sensory processing difficulties were more related to emotional and behavioral issues.

This study was conducted to investigate the food behavior during the childhood, the influence of food behavior on internalizing and externalizing behavior problems, and the pattern of influence of food behavior on behavior problem depending on children's age and gender. A total of 171 children aged 5 and 6 years were selected who attended 3 nurseries and 1 kindergarten in Seoul, and the survey data responded by teachers were analyzed. The results were as follows. First, children with higher levels of food behavior showed less internalizing behavior problems compared to those with lower levels of food behavior. The main effects and interaction of gender and age were not significant. Second, children with higher levels of food behavior showed less externalizing behavior problems compared to those with lower levels of food behavior. For hyperactivity, interaction of age and food behavior was significant, and age and the interaction of age and food behavior affected children's agression. Food behavior of children affects behavior problem and, therefore, children with better food behavior showed less behavior problems in the same circumstances.

Objective: The purpose of this study was to explore the structural relationships among duration of media use, behavior problems, and school adjustment, while accounting for gender differences. Methods: The study used 4th-wave panel data from the Korean Children and Youth Panel Study, and 2,119 first graders in elementary school were analyzed. The data were analyzed using Structural Equation Modeling. Results: The results can be summarized as follows. First, the duration of media use had a direct effect on school adjustment. Secondly, the duration of media use had an indirect effect on school adjustment through internalizing and externalizing problems. According to multigroup analysis, gender differences were found in the structural relations among variables. Conclusion: This study emphasizes the needs for media usage education to improve children's school adjustment. Furthermore, it suggests that different intervention strategies for internalizing/externalizing behavior problems are needed depending on gender.

This study investigated the effects of Korean parents' family-of-origin experiences, marital conflict, open or dysfunctional communication with their children, children's coping behaviors on their behavior problems as a function of a child's sex. Theoretical models for both sexes were constructed based on the results. Two hundred and nine boys and one hundred and ninety six girls of 4th and 5th grades from two elementary schools filled out the questionnaires to assess their communication with the parents, their problem-focused coping behaviors, and their internalizing and externalizing behavior problems. Four hundred five parents of these children answered the questionnaires to assess differentiation for the family-of-origin and the marital conflict. The results were as follows. Boys' path pattern showed that the fathers' differentiation from the family-of-origin effected their sons' internalizing and externalizing behavior problems through parent-child dysfunctional communication. Girls' path exhibited two different patterns. One is that the mothers' differentiation from the family-of-origin effected their daughters' internalizing and externalizing behavior problems through parent-child dysfunctional communication. Another one is that the mothers' differentiation from the family-of-origin influenced children's internalizing behavior problems through daughters' problem-focused coping behaviors as well as parent-child dysfunctional communication.

The relationship between children's behavior problems and perceptions of their parents' childrearing behaviors was studied in 359 fourth graders. Children reported on perceptions of their parents' childrearing behaviors with the Childrearing Behavior Questionnaire (Park, 1995) and on their own behavior with the Korean Youth Self-Report (K-YSR; Oh, Lee, Hong, & Hah, 1997). Data were analyzed with descriptive statistics, t-test, and hierarchical multiple regression. Results showed that girls viewed their fathers and mothers as more warm/accepting and their fathers as less rejecting/restricting than boys. Boys had more externalizing (aggressive/delinquent) behavior problems than girls. Children's internalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and permissive/non-interfering. The relationship was differed as a function of child's sex. Children's externalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and paternal permissive/non-interfering. The relationship was differed as a function of child's sex.

Participants in this study were 1.245 4th and 5th graders and their parents from 8 elementary schools in Seoul, Daejeon, and Pusan. Using the Korean Youth Self-Report (K-YSR), children's behavior problems were measured and assigned to either clinical or normal groups. Between group differences were that the educational level of mothers of internalizing girls was lower than that of normal girls. Girls with internalizing problems had more siblings than normal girls. Parents of both boys and girls with either internalizing or externalizing problems were more rejecting and/or permissive than parents of children without behavior problems. Fathers of children with behavior problems perceived more marital conflicts, while mothers whose children have behavior problems had more negative family-of-origin experiences compared to parents of normal children.

This study focused on the links between emotionality, interpersonal and intrapersonal intelligence, and behavior problems in a sample of 185 four- to five-year-old children in kindergarten and daycare centers in Seoul. All variables were measured by the teachers of surveyed children. Collected data were analyzed by Simple Regression and Hierarchical Multiple Regression. The main results of this study were as follows: Firstly, children's positive and negative emotionality each exerted negative and positive effects on their interpersonal and intrapersonal intelligence. Secondly, children's positive emotionality had a negative influence on internalizing behavior problems. On the other hand, children's negative emotionality had a positive influence on internalizing and externalizing behavior problems. Finally, effect of children's positive emotionality on their internalizing behavior problems was totally mediated by interpersonal and intrapersonal intelligence. On the other hand, effect of children's negative emotionality on their internalizing and externalizing behavior problems was partially mediated by their interpersonal and intrapersonal intelligence.

Objectives: The aim of this study was to examine the relationship between personality of parent and offspring, and offspring's psychological adaptation. Methods: We examined temperament and character of 65 parents and their offspring (measured using the Junior Temperament and Character Inventory and Temperament and Character Inventory) and offspring's internalizing (anxiety, depression) and externalizing (delinquency, hyperactivity) problems. Results: The internalizing problems of offspring were positively associated with harm avoidance (HA) of offspring and parent, and negatively associated with self-directedness (SD) of offspring and parent. The externalizing problems of offspring were positively associated with novelty seeking of offspring, and were predicted by SD of parent. The interaction between parent's HA and offspring's HA predicted higher levels of anxiety of offspring. Conclusion: The association between the offspring's personality and internalizing and externalizing problems can depend on the personality of the parent.
