This study investigates: (1) children's proactive aggression according to age and the emotional condition of the counterpart child, (2) if children's intention attribution, emotional attribution (victim and perpetrator) and language ability influences proactive aggression according to age and the emotional condition of the counterpart child. The subjects were 68 3-year-old and 70 5-year-old children. Each child was individually interviewed with picture cards. Collected data were coded and analyzed in SPSS with frequencies, percentiles, means, standard deviations, repeated measures analysis of variance (ANOVA), t -tests, Pearson correlations and multiple linear regression. The results showed that 3-year-old children showed more proactive aggression and physical aggression than 5-year-old children. They showed more proactive aggression when counterpart child was in a happy condition than in a fear condition. Intention attribution, emotional attribution, and language ability partially affected a children's proactive aggression according to age and the emotional condition of the counterpart child. This study has practical implications for teachers in regards to children's proactive aggressive behavior at child care centers. Teachers use specific to develop advantages as the basis for developing aggression prevention programs that consider emotional and cognitive factors.

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.

Purpose: This study was done to explore the relationship between aggression and internet over-use, depression-anxiety, self-esteem, all of which are known to be behavior and psychological characteristics linked to "at-risk" children for aggression. Methods: Korean-Child Behavior Check List (K-CBCL), Korean-Internet Addiction Self-Test Scale, and Self-Esteem Scale by Rosenberg (1965) were used as measurement tools with a sample of 743, 5th-6th grade students from 3 elementary schools in Jecheon city. Chi-square, t-test, ANOVA, Pearson's correlation and stepwise multiple regression with SPSS/Win 13.0 version were used to analyze the collected data. Results: Aggression for the elementary school students was positively correlated with internet over-use and depression-anxiety, whereas self-esteem was negatively correlated with aggression. Stepwise multiple regression analysis showed that 68.4% of the variance for aggression was significantly accounted for by internet over-use, depression-anxiety, and self-esteem. The most significant factor influencing aggression was depression-anxiety. Conclusion: These results suggest that earlier screening and intervention programs for depression-anxiety and internet over-use for elementary student will be helpful in preventing aggression.

The present study examined the effects of child maltreatment and self-control on reactive aggression amongst middle-school students and investigated whether students' self-control had any form of moderating effect on the relationship between child maltreatment and reactive aggression. The participants of this study consisted of 482 students (204 boys and 278 girls) from four middle schools located in Seoul and Gyoung-gi province. The Peer Conflict Scale (Marsee, Kimonis, & Frick, 2004) was used to measure the level of reactive aggression. The level of child maltreatment was assessed by means of the Child Trauma Questionnaire (Bernstein & Fink, 1998). Self-control was measured by the Self-Control Scale (Nam, 1999). Statistical analyses of data used for this study comprised the following methods; frequency, mean, standard deviation, and hierarchical regression. The moderating effect of self-control was analyzed by using the procedures proposed by Baron and Kenny (1986). The results indicated that the level of child maltreatment increased the level of reactive aggression whereas the level of self-control decreased the level of reactive aggression. In addition, self-control moderated the influence of child maltreatment on student's reactive aggression. As a result, the influence of child maltreatment upon reactive aggression was greater when the level of self-control was low, compared to when it was high.

This study examined the effects of children's negative emotionality, emotional regulation, and maternal parenting behaviors on their relational and overt aggression. The participants were 355 children(174 boys, 181 girls; aged 4-5 years old) and their mothers. The teachers completed rating scales to measure the children's aggression and emotion regulation. The children's negative emotionality and maternal parenting behaviors were assessed by a mother reported questionnaire. The collected data was analyzed using descriptive statistics, t-tests, correlations, and hierarchical multiple regressions. Results showed that Children's negative emotionality was positively related to their relational and overt aggression. Children's emotional regulation had a negative relation to their relational and overt aggression. Mother's limit-setting and rejection-neglect was significantly related to children's relational aggression, whereas mother's warmth-encouragement and rejection-neglect was negatively related to children's overt aggression. Hierarchical regression analysis indicated that the interaction of children's negative emotionality and mother's overprotection-permission predicted children's overt aggression. Children's negative emotionality, whose mothers demonstrated middle and high level of overprotection-permission, was associated significantly with overt aggression. In addition, the association between mother's parenting behaviors and children's aggressions were mediated by their emotion regulation. The findings point to similarities and differences between relational and overt aggression in relation to children's negative emotionality, emotional regulation and maternal parenting behaviors.

This study explored the relationship between children's emotional competence, aggression and peer relationships. Participants were 164 third and 134 fourth grade children from five elementary schools in Seoul and Chenan. Emotional competence, aggression and peer relationships were assessed by means of a questionnaire, interview and observation. Results indicated that emotional understanding of self and others, sex, age, emotional expression and passive regulation strategies were significant variables in predicting children's aggression. Emotional understanding was the most predictable variable in relation to peer relationships. Emotional understanding, emotional regulation and emotional expression made independent contributions to aggression and peer relationships. Mediation analyses revealed that the significant connections between children's emotional competence and negative peer relationships were mostly mediated by aggression.
