Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

Purpose: This study aimed to identify the reciprocal relationship between parenting attitudes (positive and negative) and adolescent emotional problems as indicated by aggression, social withdrawal, and depression. Methods: This study analyzed longitudinal data from 2,325 parents and their children from the Korea Children and Youth Panel Survey 2018 at three time points over a three-year period (the first to third grade of middle school). Autoregressive cross-lagged modeling was conducted using AMOS 26.0. Results: The results indicated that both parenting attitudes and adolescents' emotional problems were relatively stable over time. In other words, the parenting attitude at a previous point affects the parenting attitude at a later point, and the emotional problem at the previous point continues to affect the emotional problem at the later point. There were no significant cross-lagged effects from both positive and negative parenting attitudes to adolescents' emotional problems. In contrast, adolescents' emotional problems at previous time points positively predicted negative parenting attitudes at later time points. In other words, if there were many emotional problems of aggression, social withdrawal, and depression in adolescents at a previous time, negative parenting attitudes such as rejection, force, and inconsistency at a later time increased. Conclusion: This study can reflect the characteristics of the development of independence in adolescence. Parents should deal with their children's emotional problems based on their understanding of the developmental characteristics of adolescence, and this study provides a strategy for parents to establish appropriate parenting attitudes for adolescents with emotional problems.

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.

This study examined the effect of parental achievement-oriented expectation on high school students' depression and verified the mediating effect of peer relations on relations. Data were derived from the 7th wave (2016) of Korean Children and Youth Panel Survey (KCYPS), and 1,979 high school students were included. Descriptive statistics analysis, correlation analysis, multiple regression analysis, and a Sobel test were conducted using STATA. The main results were as follows. First, male adolescents perceived higher parental achievement-oriented expectation, lower peer relations, but lower depression than female adolescents. Second, parental achievement-oriented expectation was negatively related to adolescent peer relations but positively related to adolescent depression. This implies that adolescents whose parents have a higher level of achievement-oriented expectation have lower level of peer relations and higher level of depression. Third, adolescents' peer relations significantly mediated the relation between parental achievement-oriented expectation and high school students' depression. The result of Sobel test supported the significance of the mediating effect. The results highlighted a negative impact of parental achievement-oriented expectation on adolescents' mental health, and addressed how parental achievement-oriented expectation affects adolescents' depression by showing an important mechanism of peer relations, which was missed in previous research.

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.

This study examined the effects of parenting behavior perceived by children and ego-resilience on school adjustment according to child gender. The participants were 2,119 first grade students(1,093 boys, 1,026 girls) in the fourth Korea Youth Panel Survey. The results of this study were as follows : First, boys perceived parenting behavior more positively than girls. Girls perceived more difficulty in ego-resilience and school adjustment than boys. Second, school adjustment of the boys and girls showed a positive correlation with parenting behavior perceived by children and ego-resilience. Third, the more perceived positive parenting behavior and the better perceived ego-resilience, the better the boys and girls could make adjustment in school. The results of this study offers a fundamental data about parenting behavior and ego-resilience which can improve the school adjustment of a first grade student.

This study aims to examine developmental trajectories and predictor variables of problem behaviors and school adjustment trajectories among children from low-income families using latent growth modeling. The data was collected from the 2nd year to the 4th year (2012-2014) of a community child center child panel survey conducted by the National Youth Policy Institute. The major findings are as follows. First, as the grade went up, the problem behaviors of children from low-income families increased while school adjustment decreased. Second, multi-level domains, such as individual, school, and family variables influenced school adjustment trajectory, while only individual variables, such as depression, isolation, and motivation for achievement influenced problem behavior trajectory. Third, common protective factors between problem behaviors and school adjustment trajectories were motivation for achievement in and satisfaction of the community child center. Common risk factors between problem behaviors and school adjustment trajectories were isolation and aggression. Based on the results, the implications for child welfare practices were discussed.

This study examined the effect of private educational expenditure on adolescent depression and somatic symptoms. The sample comprised 2,589 first-grade middle-school students who completed the 2018 Korea Children and Youth Panel Survey. Data were analyzed using ANOVA (the generalized linear model), multiple regression, and quantile regression analysis. The principal results were as follows. First, 15.15% of adolescents reported depression symptoms, and 15.57% reported somatic symptoms. Second, levels of depression were significantly different among classes with a different level of private educational expenditure. Third, depression level was significantly negatively associated with private educational expenditure, in that the higher the private educational expenditure, the lower the depression level. Fourth, the effect of private educational expenditure on adolescent depression was significant at the 70~90th quantile regression, suggesting that private educational expenditure was associated with a higher level of depression symptoms. The results indicate that private education was viewed as a consumption commodity rather than a complementary educational practice or investment in human capital. Private education as a commodity might induce the highly developed and costly private education market. In turn, there is an increased financial burden for education at one end of the social-economic continuum and depression caused by relative deprivation at the other end.

This study aimed to investigate the effect of adolescent development environment including parenting attitude, peer relationship, and school environment on delinquent behavior, and between these relationships, the mediate effect of media environment such as computer and mobile devices. The $6^{th}$ year data from Korean Children & Youth Panel Survey (KCYPS) was used and the subjects were limited to 518 students of $7^{th}$ grade who are in their early adolescence. The result shows that adolescents under more affectionate, over involvement, and abusive parenting attitude will commit delinquent behaviors more frequently, and so does alienated youth from their friends. Parenting inconsistency and communication with friends make them use computer and cell phone more often, and excessive media usage increases adolescent's delinquent behavior. In conclusion, family environment and peer relation have influence on adolescents' delinquent behavior. Therefore, there is necessity to build development environment that prevent adolescents' delinquencies like parent education program or peer communication program for example. Also, proper education program for using computer or cell phone usage can reduce adolescents' delinquent behaviors, especially when its addictive aspect was recently issued.
