The purpose of this research was to analyze the trajectory of child's academic attainment and the effect of family socioeconomic background on the trajectory. Data were part of the Korea Youth Panel Survey 2003-2005(Middle School 2) and were analyzed by Latent Growth Curve Modeling(LGM). The degree of child's academic attainment decreased over 3 years. Socioeconomic status variables that influenced academic trajectory were family poverty, parent's attainments in scholarship, and family structure. Findings from this study suggest that societal support for low socioeconomic status families is needed for improvement of academic attainment of their children.

Objective: The purpose of this study was to investigate trajectories of child peer interaction and to compare the causal effects of their predictors, including child individual variables (i.e., gender, language ability, and cognitive ability) and teacher variables (i.e., teacher efficacy and teacher-child interaction). Methods: The participants of this study were 263 children and their teachers from the forth to sixth waves of longitudinal data from the Korean Children and Youth Panel Survey by the Korea Institute of Child Care and Education. The data was analyzed using Pearson's correlation and latent growth modeling. Results and Conclusion: The findings of this study are as follows: First, there was a linear decrease in child negative peer interaction over the course of 3 years, and significant individual differences were found in the trajectories (intercept and slope). Second, the predictors had significant casual effects on the trajectories of child negative peer interaction. The trajectories of child negative peer interaction involving girls, higher cognitive ability, and greater teacher-child interaction showed lower degree of intercept and a quicker decrease. Finally, the implications of findings are discussed.

The purpose of this study was social withdrawal, depression, and self - esteem affect adolescents' mobile phone dependency. For this study, I used data from the first grade of junior high school during the 7th (2016) Korean child and youth panel survey provided by Korea Youth Policy Institute. A total of 1,937 people were selected as the final target except those who do not have a mobile phone. The analysis method was SPSS 23.0 and AMOS 20.0. As a result of the study, First, the higher the depression of adolescents, the higher the dependence on mobile phones. Second, the social withdrawal and depression of adolescents have a significant impact on mobile phone dependence through self-esteem. In conclusion, I would like to provide policy data so that youths can develop and implement preventive programs that can prevent personality education and erroneous mobile phone dependency that can develop healthy and positive growth.

This study examined the effects of parental attachment and peer attachment in elementary school children upon early adolescent delinquency. The participants were 2,844 taken from data from the Korean Youth Panel Survey (KYPS). Data from secondary questionnaires data on parent and peer attachment, problem behavior, delinquent peers, and delinquency were used for this study. Data were analyzed by means of a Structural Equation Model using AMOS 5.0. Our results indicated that, firstly, parental attachment was negatively related to problem behavior for both male and female adolescents, whereas peer attachment was positively related to problem behavior only for males, but not for females. Secondly, problem behavior in childhood has a direct effect on adolescent delinquency, which also can be indirectly mediated by contact with delinquent peers. In conclusion, the path model from parental and peer attachment in early childhood to adolescent delinquency was supported only in the case of males.

This study examined the effects of negative parenting attitudes on adolescents' academic helplessness through the mediating effects of social withdrawal and smartphone dependency. Data from the panel study of Korean Children and Youth Panel Survey 2018 (KCYPS 2018) collected by the National Youth Policy Institute (NYPI) was used to examine the research model. The subjects of the study consisted of 2,541 first grade middle school students (1,375 boys and 1,166 girls). Confirmatory factor analysis [CFA], structural equation modeling [SEM], and bootstrapping analysis were conducted by means of SPSS 25.0, AMOS 25.0, and Hayes's PROCESS programs to examine the serial multiple mediating effects. The study results were as follows. First, negative parenting attitude had a direct effect on adolescents' academic helplessness. This implies that adolescents who perceive their parents' attitudes to be high in coercive, rejective, and chaotic levels indicate that they can easily get exhausted in academic settings. Second, negative parenting attitudes had an indirect effect on adolescents' academic helplessness through social withdrawal and smartphone dependency. The results suggest that a high level of negative parenting attitude leads to higher social withdrawal and smartphone dependency that influences adolescents' academic helplessness.

The purpose of this study was (1) to examine the impact of chronic diseases on adolescent's peer relationships, and (2) to investigate the mediating effect of self-perceived health status and resilience on the relationship between their physical health states and peer relationships. The authors used the first-wave panel data from 'the Korean Children-Youth Panel Survey'. The sample included 2,351 first-grade of middle school students(boys 50.1%, girls 49.9%). Among the subjects examined 48.11% had chronic diseases. Using maximum likelihood estimation with Amos18(Arbuckle, 2009), SEM software, structural equation modeling was tested. The major findings were as follows : 1. Adolescents' chronic diseases had a negative impact on peer relationships. 2. Self-perceived health status and resilience had a mediating effect. This suggests that self-perceived health status and resilience could be protective factors when it comes to perceive peer relationships more positively for adolescents with chronic diseases. 3. Resilience was directly affected by self-perceived health status. This indicates that positive self-perception about their health status encourages adolescents with chronic diseases to be more resilient and to more positively affect their perception of their relationships with peers.

The purposes of this study is to analyze gender difference in predictors of mobile phone dependency in youth. The analysis is performed with third-year panel survey data of middle school 1st grade students from Korean Child-Youth Panel Survey. The results are as follows. First, the female students' mobile phone dependency is more serious than the male students' mobile phone dependency. Second, while the identified male gender predictors are aggression, parental abuse, aprosexia, study activity and social withdrawal, the identified female gender predictors are depression, aprosexia, aggression, study activity and social withdrawal. Based on these results, theoretical and practical implications in planning of prevention or intervention of mobile phone dependency are proposed.

The aim of this study is to verify whether mediated effect on classmates and teachers occurs while child abuse and neglect have an effect on community sense. For the purpose of this study, among the Korean Children and Youth Panel, data of freshmen from elementary school are gathered through a follow-up survey for 7 years(2010-2017) and data of about 2,001 children are investigated. Also, The research issue -'will there be mediated effect in the relationship between child abuse and neglect and community sense'- is verified by the structural method and presented as follows. First, child abuse and neglect have no significant effect on community sense directly. Second, child abuse and neglect(β=-.663) are found to have a negative influence meaningfully on relationship with classmates and teachers. Third, relationships with classmates and teachers(β=.664) are shown to have a significant positive effect on community sense. Fourth, When child abuse and neglect have an influence on community sense, mediated effect on classmates and teachers(β=-.440) has a meaningful negative effect, Based on these findings, the recommendations for implementing youth welfare are described.

Objectives: The purpose of this study is to develop programs that help students adjust to school and provide basic data for the students who have difficulty adjusting to school by analyzing the influence of elementary school students' stress and their relationship with parents on school adjustment. Methods: The study surveyed fourth graders in 3 elementary schools in G district. The researcher used convenience sampling to select the 3 elementary schools. The combined 158 students were selected for the analysis, and the survey was conducted for a month in September 2011. The stress monitoring tool used in the 5th year of Korean Youth Panel Survey was mobilized to measure levels of stress among the participants. To measure the parent-child relationship, the Korean Parent-Child Relationships Scale was used. For the measurement of school adjustment, a tool designed to identify the school adjustment of elementary school students was used. The SPSS 21 software and a two-sided test under the significance level of ${\alpha}=0.05$ were used to analyze data. The regression analysis was also used to identify the relative influence of the stress and parent-child relationship on children's adjustment to school. Results: The regression analysis has found the following: the higher peer stress (B=-0.175) and parental strictness (B=-0.159) grow, the lower the level of school adjustment gets; the higher the level of intimacy between parent and child gets, the higher the level of school adjustment grows; and intimacy between parent and child (${\beta}=0.400$) has the largest influence on the child's school adjustment. Conclusions: For elementary school students to be well adjusted to school, their stress and relationships with their parents should be managed. In particular, using the programs that can reduce stress from peers and increase parent-child intimacy will be effective in helping students adjust to school.
