Purpose: This study was conducted to explore the relationship between aggression, self-esteem, and social withdrawal. Methods: This research is a cross-sectional survey. This study used the 5th-year data of the Korean Children & Youth Panel Survey (KCYPS) including 218 middle school students having delinquent behavior. The collected data was analyzed through $x^2$ test, t-test, ANOVA, Pearson's correlation, and hierarchical multiple regression, using SPSS/Win (ver. 23.0). Results: Significant positive correlations were found between aggression and social withdrawal and between aggression and self-esteem. Higher aggression was associated with higher social withdrawal and lower self-esteem. The results of the 2-step regression are as follows. Aggression was negatively correlated with self-esteem, whereas self-esteem was positively correlated with social withdrawals. The hierarchical multiple regression showed that 21% of the variance of aggression was significantly accounted for by self-esteem and social withdrawal. The most significant factor influencing aggression was social withdrawal. Conclusion: These results suggest that earlier screening and intervention programs to increase self-esteem and decrease social withdrawal for early adolescents should be developed to prevent aggression.

The purpose of this study was to investigate the longitudinal relationship between Korean youth's social withdrawal, depression and community sense mediated by achievement values. For this purpose, we analyzed three years of the longitudinal panel data (2011-2013) of the Korean Children and Youth Panel Survey (KCYPS). Data were collected from 2,351 first year middle school students using the latent growth model using SPSS 18.0 and AMOS 22.0. The main analysis results were as follows. First, social withdrawal and depression decreased and community sense increased as time passed. These results supported the linear change model. Second, the initial status of social withdrawal and depression had effects on the initial status and change rates of community sense. Achievement values, the partial mediator, had a positive influence on initial community sense but had a negative influence on change rates of community sense. We discussed how to improve Korean youth's community sense based on these results.

This study investigated social determinants and their interaction effects on the health of school-aged children in diverse environmental factors pertaining to the individual, family, and peers from an ecological systematic perspective. Data were drawn from the first wave of the Korean Children and Youth Panel Survey (KCYPS) developed by the National Youth Policy Institute and conducted in 2010. Data were analyzed by descriptive statistics, Cronbach ${\alpha}$, correlation, and hierarchical regression analysis using SPSS ver. 18. The results from this study showed that sex and age were related to the health of school-aged children, as social determinants. Self-rated levels of the health of boys and younger children were more positive than girls and older children; in addition, levels of self-resilience, satisfaction of peer relation, and parenting rearing attitude were found to have a positive impact on self-rated levels of the health of school-aged children as protective factors. Especially, according to the result of interaction analysis between factors, self-resilience, and parenting rearing attitude were moderators of the effects on between sex and household income and self-rated level of the health of school-aged children respectively. The findings from this study suggested the need to expand the social intervention range to improve school-aged children's health.

The purpose of this study was to examine the effects of parental abuse and neglect, as well as that of children's peer attachment, on mobile phone dependency. Data were obtained from the Korean Child-Youth Panel Survey (KCYPS), and the participants were 1,892 (909 boys, 983 girls) elementary students (5th graders) who had a mobile phone. To measure the variables, this study used such scales as the parental abuse and neglect scale, peer attachment scale, and mobile phone dependency scale. The data were analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling analysis. The results of the study were as follows: First, parental abuse and neglect had direct negative effects on children's peer attachment; that is, the more parental abuse and neglect, the less children's peer attachment. Second, parental abuse and neglect had direct positive effects on mobile phone dependency; that is, the more parental abuse and neglect, the greater children's mobile phone dependency. However, children's peer attachment did not directly affect mobile phone dependency; that is, children's peer attachment did not have a mediating effect between parental abuse and neglect, and mobile phone dependency. In conclusion, parental abuse and neglect influence children's peer attachment and mobile phone dependency. Thus this study showed that parental abuse and neglect, rather than children's peer attachment, affect children's mobile phone dependency.

In order to analyze the prediction of the computer entertainment behavior, this study investigated the variables' interdependencies and their causal relations to the computer entertainment behavior using Bayesian inference with the Korean Children and Youth Panel Survey data. For the study, Markov blanket was extracted through General Bayesian Network and the degree of influences was investigated by changing the variables' probabilities. Results showed that the computer entertainment behavior was significantly changed depending on adjusting the values of the related variables; school learning act, smoking, taunting, fandom, and school rule. The results suggested that the Bayesian inference could be used in educational filed for predicting and adjusting the adolescents' computer entertainment behavior.

Objectives: This study was conducted to analyze the mediating effect of self-identity on the relationship between aggression and school life adaptation of early adolescents. Methods: This study used the 5th-year data of the Korean Children & Youth Panel Survey (KCYPS) including 159 middle school 2nd students from single-parent families. The data was analyzed with open source statistics program R 3.5.0 to determine whether self-identity had a mediating effect on school life adaptation as an independent variable. Results: A moderate correlation was found among aggression, self-identity, and school life adaptation. As a result of the Sobel test, self-identity of early adolescents demonstrated a significant mediating effect on the relationship between aggression and school life adaptation. Conclusions: Given the significant mediating factor of self-identity, the strategies for early adolescents to boost their overall school life adaptation should be considered through intervention programs that help to enhance their self-identity.

Although longitudinal studies mainly produce multivariate longitudinal data, most of existing statistical models analyze univariate longitudinal data and there is a limitation to explain complex correlations properly. Therefore, this paper describes various methods of modeling the covariance matrix to explain the complex correlations. Among them, modified Cholesky decomposition, modified Cholesky block decomposition, and hypersphere decomposition are reviewed. In this paper, we review these methods and analyze Korean children and youth panel (KCYP) data are analyzed using the Bayesian method. The KCYP data are multivariate longitudinal data that have response variables: School adaptation, academic achievement, and dependence on mobile phones. Assuming that the correlation structure and the innovation standard deviation structure are different, several models are compared. For the most suitable model, all explanatory variables are significant for school adaptation, and academic achievement and only household income appears as insignificant variables when cell phone dependence is a response variable.

This study investigated the influence of life satisfaction, accomplishment value, peer attachment, and relationship with teachers on the self-esteem of adolescents in three time points. The study population consisted of a nationally representative sample of middle school 1st grade students who completed the Korean Children and Youth Panel Survey(KCYPS) of the National Youth Policy Institute in 2010, 2012, and 2014. Descriptive statistics used included frequency, percentage, average, and standard deviation; in addition, reliability, repeated measure ANOVA, and regression results were reported using SPSS statistics. The results were as follows. First, this study showed that the longitudinal changes of self-esteem, life satisfaction, accomplishment value, peer attachment, and relationship with teachers were significantly different across three time points. Second, longitudinal changes in adolescents' self-esteem, life satisfaction, peer attachment, and relationship with teachers differed by gender, but accomplishment value did not. Third, life satisfaction was the most influential to self-esteem and peer attachment was the second most influential in the three data sets after controlling for gender, parents' academic attainment, and residential area. The influence of life satisfaction on self-esteem decreased across the three time points, but that of peer attachment increased over time. Instruction on life satisfaction and peer attachment needs to be more highlighted in Home Economics classes to enhance the self-esteem of adolescents.

The purpose of the present study was to investigate the effect of child neglect and abuse by parents on school adjustment of school-aged children focusing on mediating effect of school-aged children's self-awareness and peer attachment. For this purpose, we analyzed the data of fourth wave Korean Child-Youth Panel Survey(KCYPS) including parents' child neglect and abuse, school-aged children's school adjustment, self-awareness and peer attachment. A total of 2,378 children and their parents using structural equation model of mediating effects responded to the survey. Measurement model and structure model had favorable goodness of fit and the results of structure models on each path were as follows. First, school-aged children's school adaption had negative correlations with parent's child neglect and abuse, but positive correlations with their self-awareness and peer attachment. Second, parent's child neglect and abuse influenced on school-aged children's school adjustment by partial mediators, their self-awareness and peer attachment. These findings showed practical way to increase school-aged children's self-awareness and positive peer attachment.

This study analyzes the moderating effects of the self-esteem on the life satisfaction of 2,040 middle school senior students using the Korean Children and Youth Panel Survey 2012 Data (KCYPS 2012) provided by the National Youth Policy Institute. The path analysis of how environmental characteristics, such as parents, friends, and school, affect life satisfaction, is based on four groups of self-esteem, categorized by positive and negative self-evaluation levels. The analysis suggests that groups with higher levels of positive self-evaluation have closer relevance in more paths than other groups. Furthermore, in groups with higher levels of negative self-evaluation, negative effects on life satisfaction are offset by positive self-evaluation. These results suggest research associated with the mental health of adolescents and their self-esteem should be performed according to two separate levels of self-esteem: positive self-evaluation and negative self-evaluation. Since low levels of negative self-evaluation doesn't necessarily guarantee high levels of positive self-evaluation, counseling for adolescents needs to have different tracks, addressing positive and negative self-evaluation levels.
