The purpose of this study was to explore the relationship between children's playfulness, the degree of preschool adjustment and behavior problems. The subjects were 118 children from 3 child care centers and 5 kindergartens in Kyungbuk province. Children's playfulness was measured through the children's playfulness scale (CPS) and the level of preschool adjustment was measured through the preschool adjustment questionnaire (PAQ). The modified version of Kim's (2000) Preschool Behavior Questionnaire (PBQ), created by Behar and Stringfield (1974) was used to measure the acceptability of children's behaviors. The regression and correlation analysis was performed through the use of SPSS 12, and the findings are as follows. First, there exists a meaningful correlation between the children's playfulness, the degree of preschool adjustment, and the acceptability of behavior problems. Second, the degree of preschool adjustment appears to be a reliable predictor of children's playfulness.

This study investigates the moderating effects of the teacher-child relationship on the relationship between young children's self-control and behavior problems. 150 young children aged 3, 4, and 5 and their 40 classroom teachers participated in this study. The results of this investigation reveal the following: (1) Young children's self-control is significantly related to behavior problems. (2) The teacher-child relationship (conflict, dependence, intimacy) is significantly related to young children's behavior problems. (3) The effects of self-control on young children's anxiety and withdrawal behavior are significantly moderated by conflict driven teacher-child relationships. (4) The effects of self-control on young children's aggression and impulsive behavior are significantly moderated by dependent teacher-child relationships.

This study investigated institutionalized children's behavior problems depending on their cognitive abilities. Subjects were 185 institutionalized children in 15 child-welfare facilities in Seoul (132 preschooler and 153 primary schoolers; 106 boys and 79 girls). Institutionalized children's cognitive abilities were measured using the Comprehension and Picture Completion Assessment, two subsets of K-WPPSI (Park et al., 1996) Comprehension and Picture Completion Assessment belong to verbal and performance scale, respectively. Measures of behavior problems included anxiety, immaturity, social withdrawal, physical symptom, hyperactivity, and aggression. Data were analyzed with mean, standard deviation, and t-test. Results showed that institutionalized children had higher scores in Picture Completion Assessment than Comprehension Assessment. Furthermore, institutionalized children with low scores in Comprehension Assessment were higher in anxiety and social withdrawal than children with high scores in Comprehension Assessment.

This study explored moderating effects of parental attachment andparental monitoring in the relationship between stress and problem behavior among Korean adolescents. The Korean Youth Panel Study (KYPS) was used as sample data with a total of 2,503 11th grade students involved in this study. Results of hierarchical regression analyses showed that parental attachment (for both male and female adolescents) and parental monitoring (for male adolescents) played the role of moderators in the relationship between stress and problem behavior. That is, good parental attachment and monitoring reduced stress inducing problem behavior for male adolescents but only parental attachment reduced stress inducing problem behavior for female adolescents. Conclusions highlighted the importance of parents' role in the prevention of adolescent problem behavior.

This study investigated the behavior problems of children, both institutionalized and home-reared, depending on their sex, age, and entry to institution. The subjects included 621 children (274 institutionalized, 347 home-reared; 298 boys and 323 girls; 209 preschoolers, 223 first to third graders, 189 fourth to sixth). The data collected were analyzed with t-test, 3-way ANOVA, Scheffe test, and Pearson's correlation. Children's emotionality had two sides: Positive (happiness) and negative (sadness, anger, and fear). Measures of behavior problems included internalization (anxiety, immaturity, withdrawal, physical symptom) and externalization (hyperactivity, aggression). The results of this study indicated that the institutionalized were higher in negative emotionality than their counterparts, whereas the home-reared higher in positive emotionality. The institutionalized children also had higher externalizing problems than the home-reared. Furthermore, children's negative emotionality was positively related to their internalizing and externalizing behavior problems, while their positive emotionality was negatively related to the internalizing behavior problems.

The purpose of this study was to identify developmental trajectories of externalizing problems in preschoolers and to investigate dimensions of temperament and parental behaviors associated with trajectory groups. Subjects were 180 3- to 5-year-old preschoolers (96 males, 84 females) in the metropolitan area of Seoul. They were assessed three times at 5 month intervals over a one year period. Teachers reported on children's behavior problems, and parents reported on children's temperaments. Latent Growth Curve Modeling Analysis with cohort sequential design revealed externalizing behaviors gradually decreased between 3 and 6. At the 6-year-old level externalizing behaviors were associated with high novelty seeking temperament. The results were discussed in terms of the importance of longitudinal research in developmental psychopathology.

The purpose of this research was to study the effects of children's temperament, social competence, emotional intelligence, morality and parent's child rearing attitudes on young children's internalizing and externalizing problem behavior. Subjects were l34 five-year-old children attending day-care centers and kindergartens in Seoul, Korea. Analysis of the relationships among these variables was by correlation and stepwise multiple regressions. There were statistically significant correlations among the variables of temperament, social competence and parents' child rearing attitudes and young children's behavior problems. Variables influencing young children's internalizing behavior problems were children's temperament and parents' child-rearing attitudes; variables influencing children's externalizing behavior problems were children's temperament, their social competence, and parents' child-rearing attitudes.

This study investigated institutionalized children's behavior problems depending on their family networks. Subjects were 250 institutionalized children in 15 child-welfare facilities in Seoul(132 preschooler, 55 first and 63 second grade children; 144 boys and 106 girls). Data were analyzed with t-test, ANOVA, and Duncan test. Measures of behavior problems included internalizing (anxiety, immaturity, withdrawal, physical symptom) and externalizing behavior problems (hyperactivity, aggression). Results showed that institutionalized children having parents were higher in internalizing problems than children not having parents, while children living with siblings in the facilities were lower in externalizing problems than children living without siblings. Furthermore, institutionalized children having parents and living without siblings were higher in both internalizing and externalizing problems than children not having parents and living with siblings.

The subjects in this study of parenting attitudes, children's behavior problems and attention ability were 111 5-year-old children and their parents. Data was analyzed by mean, frequency, percent, three-way ANOVA, and Pearson's correlation. Results showed that behavior problems and attention ability of children varied by the parenting attitude of mothers and fathers. Behavior problems of boys were higher than girls, and boys' attention abilities were lower than girls.' Interaction effects were found between parenting attitudes and gender in children's behavior problems and attention ability : fathers' autonomy correlated negatively with boys' behavior problems (r=-.47), task processing speed (r=-.37), and attention inconsistency (r=-.36). Children's behavioral problems correlated positively with attention inconsistency (r=.28).

This study examined the relationships between children's perceptions of mother's psychological control, and children's behavior problems(depression, anxiety, withdrawal, and aggression). In order to expand the study on the relationships, special attention was given to the possible mediator effects of children's emotional autonomy on the relationships. The subjects were 293 6th graders residing in Cheonan. It was found that children's perceptions of mother's psychological control was significantly related with the level of children's depression, anxiety, withdrawal, and aggression. Children's emotional autonomy were found to be a significant mediator of the relationship between mother's psychological control and children's depression and aggression. No significant mediator effect of emotional autonomy was found in the relationship between mother's psychological control and children's withdrawal and anxiety.
