Purpose: This cross-sectional study was done to compare factors influencing young adolescents' aggression according to family structure. Methods: Participants were 680 young adolescents aged 11 to 15 years (113 in single father families, 136 in single mother families, 49 in grandparent families, and 382 in both-parent families). All measures were self-administered. Data were analyzed using SPSS 18.0 program and factors affecting young adolescents' aggression were analyzed by stepwise multiple regression. Results: Levels of young adolescents' aggression and all variables were significantly different among the four family structure groups. Factors influencing young adolescents' aggression were also different according to these 4 groups. For single father families, depression-anxiety and family hardiness significantly predicted the level of young adolescents' aggression (adjusted R square=.37, p<.001). For single mother families, depression-anxiety, gender, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For grandparent families, depression-anxiety and family support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For both-parent families, depression-anxiety, family hardiness, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.48, p<.001). Conclusion: Nurses working with young adolescents should consider family structure-specific factors influencing aggression in this population.

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.

The purpose of this study was to examine the relationships between aggression and moral emotion including guilt, shame, and empathy in early adolescence. In a sample of 359 early adolescents (187 boys, and 172 girls) in Daejeon city, data were analyzed by frequency, t-test, Pearson's correlations, and multiple regressions. The following study results were obtained: 1. Boys showed more linguistic and roundabout aggression, and girls showed more anger, guilt and empathy. Older adolescents showed more shame than younger adolescents did, whereas younger adolescents showed more guilt and empathy than did older adolescents. 2. Shame had significant relationships with all types of aggression, whereas guilt and empathy had significant relationships with different types of aggression. 3. Moral emotions - guilt, shame, and empathy - showed significant effects on aggression among early adolescents. The degree of the effectiveness of moral emotions on aggression depends on the types of aggression, gender, and age of participants.

Objective: The purpose of this study was to examine the effect of adolescents' callousness on reactive and proactive aggression through moral disengagement. Methods: The participants were 315 freshmen and sophomore high school student in Korea. The data were analyzed with Structural Equation Modeling(SEM). Results: First, adolescents' callousness did not show a significant influence on reactive aggression directly or indirectly through moral disengagement. Second, adolescents' callousness had a significant influence on proactive aggression directly and indirectly through moral disengagement. That is, adolescents' high level of callousness not only predicts a higher level of proactive aggression directly, but also influences moral disengagement which may result in a high level of proactive aggression. In addition, the gender difference in this model was confirmed. Conclusion/Implications: The results of this study indicated that adolescents' callousness could have different influences on aggression through moral disengagement by the types of aggression and gender. The results suggest that it is necessary to approach the emotional and cognitive process of adolescent aggression differently, depending on the type of aggression and gender.

Purpose: This study was conducted to develop a scale for measuring aggression in adolescents, based on Ajzen's Theory of Planned Behavior (TPB). Methods: The participants were 38 adolescents in an in-depth study conducted to develop items for indirect measurement, 13 adolescents in a pre-test, and 289 adolescents in the present survey. The collected data were analyzed using content validity, the correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability, and the Cronbach's ${\alpha}$. Results: In this study, the most important variable related to aggression was found to be aggression intention. This study included 4 factors of direct measurement and 6 factors of indirect measurement; therefore, 41 questions were developed. Increased levels of aggression were associated with higher scores for attitudes of aggression, subjective norms, perceived behavioral control, and aggression intention. Conclusion: We found that the questionnaire used in this study was valid and reliable as a measurement scale to explain aggression in adolescents based on TPB. Aggression intention should be included in aggression prevention programs because it was linked to aggressive behavior.

Purpose: This study examined the fitness of a path model on the relationship among stress, self-esteem, aggression, depression, suicidal ideation, and violent behavior for adolescents. Methods: The subjects consisted of 1,177 adolescents. Data was collected through self-report questionnaires. The data was analyzed by the SPSS and AMOS programs. Results: Stress, self-esteem, aggression, and depression showed a direct effect on suicidal ideation for adolescents, while stress, self-esteem, and aggression showed an indirect effect on suicidal ideation for adolescents. Stress, self-esteem, aggression, and suicidal ideation showed a direct effect on violent behavior for adolescents, while stress, self-esteem, aggression, and depression showed an indirect effect on violent behavior for adolescents. The modified path model of adolescent's suicidal ideation and violent behavior was proven correct. Conclusion: These results suggest that adolescent's suicidal ideation and violent behavior can be decreased by reducing stress, aggression, and depression and increasing self-esteem. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes reducing stress, aggression, and depression and increasing self-esteem in order to decrease adolescents' suicide ideation and violence.

This study examines different individual, family, and school environmental variables that affect victimization by peer aggression among adolescents. The sample consists of 868 seventh and eighth graders. Statistics and method for data analysis include Cronbach's alpha, percentage, means, standard deviation, Pearson correlation, multiple regression, and hierarchical regression. The major findings of this study are as follows: First, adolescents, both withdrawn and aggressive, have lower achievement in school work. Boys experience more direct victimization by peer aggression. Adolescents, especially boys, often experience indirect victimization by peer aggression, when they become withdrawn, own lower self-esteem, and have lower achievement in school work. Second, adolescents have more direct victimization by peer aggression when their parents are negligent of them. Also, adolescents seem exposed to indirect victimization by peer aggression when they receive more physical and emotional abuse and negligence from their parents. Third, adolescents experience more victimization by peer aggression-whether it's direct or indirect, when they cannot get adjusted to peer relations and get teachers' supervision. Fourth, as to direct victimization by peer aggression, withdrawal, one of the individual variables, is the most reliable prediction followed by gender, negligence, adaptability in peer relations, aggression, and teacher's supervision in sequence. For indirect victimization by peer aggression, withdrawal is the most reliable prediction followed by adaptability in peer relations, gender, physical and emotional abuse, and negligence in sequence.

The purpose of this study was to investigate the relation of social support and aggression of early adolescents. The subject were 220 adolescents aged 11 & 14 years, who were enrolled 11 child welfare facilities or 6 public schools(3 elementary & 3 middle schools) in Seoul. That is, 110 institutionalized(IA) & 110 middle class home-reared adolescent (HA)s were examined. They subjects were asked to complete the questionnaire on social support and aggression. According to the results, 1)IAs perceived less support from peers or adults and showed more aggressive behaviors than HAs. 2)Significant sex difference was observed in aggression. Girls showed lower level of aggression than boys. 3)Adolescents' aggression was significantly correlated with social support. The more support from friends, classmates, and parents HAs perceive, the less aggression they reported. Though support from peers was correlated significantly only with anger expression, support from parents was correlated significantly with all the components of aggression. And the more support from friends and classmates HAs perceive, the less aggression they reported. These findings implicate that social support is a important factor in preventing aggressive behaviors of early adolescents.

The purpose of this study was to investigate the structural relationships among adolescents' internet addiction, self-esteem, self-control, and aggression. The participants were 300 students in their first year of middle school. The questionnaire consisted of measures of internet addiction, self-esteem, self-control, and aggression. The major findings were as follows: 1) self-control had a direct effect on aggression; 2) internet addiction had a direct effect on self-esteem and self-control; 3) self-esteem had a direct effect on self-control; 4) internet addiction had an indirect effect on aggression and self-control; and self-esteem had an indirect effect on aggression. This study implied that self-related variables could mediate the relationship between the possibility of internet addiction and adolescents' aggression. This study also suggested that research on various mediator variables could reduce adolescents' psychosocial problems.

This study aims to identify the relationship between adolescents' smart phone dependency, parenting method and aggression, and further to validate the mediating effect of parenting style between adolescents' smart phone dependency and aggression. First, adolescents' smart phone dependency has shown to have positive and negative relationships with the parenting style and aggression. Second, adolescents' smart phone dependency negatively affected their aggression through the positive parenting style, while it had a positive impact on their aggression through the negative parenting style. That is, the results demonstrated that adolescents' smart phone dependency increased their aggression, but at that time the positive parenting style such as warmth, support of autonomy, and provision of aid decreased their aggression as a mediator, whereas the negative parenting style such as refusal, compulsion, and inconsistency increased their aggression.
