The purpose of this study was to interpret relational aggression strategies in 4 year old young children's interactions in 'Sansae class' in terms of two-fold dimensions of proactivity and reactivity. Following an ethnographical approach, participative observation on young children and in-depth interviews with the teacher were employed, over the course of 30 sessions of 3 hours duration. The results are as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatening their friend' and 'withdrawal of friendship'.

The present study aims to examine the relations between emotion regulation, aggression and school adjustment of boys and girls. A total of 321 5th-6th grades students were selected for the study. The data was collected via questionnaires. As results, there were some significant differences between boys and girls in overt aggression and peer adjustment. It was also found that emotion regulation, aggression and school adjustment were significantly correlated. And school adjustment was influenced by emotion regulation as well as overt and relational aggressions. Finally, only for boys, the relations between children's emotion regulation and school adjustment were mediated by their aggression.

This study investigated age and sex differences in aggression by quality of peer relationships in 331 adolescents, 11 or 14 years of age in 6 public schools in Seoul. They completed 2 self-reported questionnaires. All subjects were divided into 3 groups by level of aggression. Highly aggressive adolescents had significant vulnerability in peer relationships as contrasted with mid- and low- aggressive groups. They reported more egocentricity, conflict, rejection, and less emotional support from peers. Fourteen-year-old reported more intimacy, more emotional support, and less physical aggression than 11-year-olds. Boys showed much more egocentricity and perceived more rejection than girls. Boys displayed more physical aggression to persons and girls showed more angry expressions. The findings suggest that various intervention programs should be provided for peer relationships of high aggressive adolescents.

The aims of this study were to investigate the effects of self-efficacy on adolescents' school adjustments and to identify mediating effects of depression and aggression. To this end, we conducted descriptive analysis, correlation analysis, and path analysis, using data from the 2008 Korean Youth Panel Survey undertaken by the National Youth Policy Institute. Our analysis shows that self-efficacy has positive effects on adolescents' school adjustments, while both depression and aggression have negative effects on adolescents' school adjustments. Moreover, both depression and aggression have a mediating effect when it comes to self-efficacy and school adjustments. These results imply that schools should consider developing a service delivery system by providing students with professional services that enhance self-efficacy. Moreover, such services will be more effective when they are combined with a program that reduces students' depression and aggression.

The purpose of this study was to determine the differences of aggression and its predictors among Korean, Korean-Chinese and Chinese adolescents. The subjects were 529(176 Korean, 168 Korean-Chinese, 185 Chinese) 9th graders from Yanji in China and Korea. Data on aggression, self-concept, attachment to mother, relationship with teachers, and victimization from peers were collected with questionnaires and analyzed by t-test, ANOVA, and multiple regression. The results showed that Korean adolescents reported the highest and Chinese adolescents the lowest on aggression. There were gender differences in proactive aggression among Chinese adolescents, and on reactive aggression among Korean adolescents. Among Korean adolescents, no gender difference was revealed. The influences of self-concept, attachment to mother, relationship with teachers, and victimization from peers differed among the groups: While attachment to mother was a significant predictor for Chinese adolescents' aggression, relationship with teachers was a significant predictor for that of Korean-Chinese adolescents', and victimization from peer was a significant predictor for that of Korean adolescents'. The differential influence of race and culture to adolescents' aggression was discussed.

Data were collected by peer nomination and sociometric nomination when children were in 4th grade and again two years later, Concurrent results of peer nominations were that prosocial children were more accepted while overtly/relationally aggressive children were more rejected by peers. Peer acceptance of males at Time 1 affected peer acceptance at Time 2. Peer rejection of females at Time 2 wasn't affected by overt aggression at Time 1. Cross-sectional results of social status were that rejected and controversial children showed higher levels of overt aggression than any other group. Popular children were most prosocial; rejected children were least prosocial. In the prospective view, aggressive males remained more rejected than any other group. Rejected children remained least prosocial.

Loneliness in adolescence was examined in relation to peer aggression /victimization and to parental attachment with sample of 426 eighth graders in a suburban city. The subjects rated themselves on questionnaires regarding attachment to parents, peer experiences, and loneliness. Peer aggression and victimization was also rated by peers. In both boys and girls, the more they were attached to parents, the less loneliness they experienced. The more aggression and victimization they experienced from peers, the more loneliness they experienced. Lonely adolescent girls had lower attachment to parents and higher self-rated victimization by peers.

This study examined the influence of bullying victimization on reactive aggression among upper elementary school students, and the mediating effect of victim justice sensitivity on the relationship between such victimization and aggression. It also investigated whether negative urgency moderates the influence of bullying victimization on reactive aggression. The participants were a group of 262 children (114 boys and 148 girls) who were fourth to sixth-grade students from 10 elementary schools located in Seoul, Gyeong-gi, and Daegu. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and SPSS Process Macro Model 5. The results were as follows: First, victim justice sensitivity mediated the influence of bullying victimization on reactive aggression among upper elementary school students. Second, negative urgency moderated the effect of bullying victimization on reactive aggression, whereas the impact of this was greater when the level of negative urgency was high. The results suggest that reactive aggression among upper elementary school students could be effectively decreased by preventing bullying victimization, and reducing the level of victim justice sensitivity and negative urgency.

This study examined relationships between children's aggression and the variables such as individual, family, and school adjustment. For this study, individual variables included age, self-esteem, and game-addiction tendency. Family variables included mother's controlling parenting, child-abuse, parents' marital conflict. As for school adjustment, teacher relations, peer relations, classroom and rule adjustment in school were examined. The sample consisted of 642 children of the fifth and sixth grade in Busan. Statistics and methods used for data analysis included frequency, percentage, Cronbach's alpha, factor analysis, two-way Anova, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis: First, boys' aggression was higher than girls'. But no age difference was found in children's aggression. Second, game-addiction tendency had a positive correlation with children's aggression. In addition, self-esteem had a negative correlation with boys' aggression. Third, mother's controlling parenting had a positive correlation with children's aggression. Child abuse had a positive correlation with boys' aggression, and parents' marital conflict with girls' aggression. Fourth, teacher relations, peer relations, classroom and rule adjustment in school had a negative correlation with boys' aggression. In addition, rule adjustment in school had a negative correlation with girls' aggression. Fifth, game-addiction tendency, rule adjustment in school, self-esteem, mother's controlling parenting and teacher relations in school were important variables predicting boys' aggression. On the other hand, game-addiction tendency and rule adjustment in school were important variables predicting girls' aggression.
