Purpose: The purpose of this study was to investigate the mediating effects of self-esteem and self-resilience while identifying the relationship between bullying victimization (being bullied) and depression based on a longitudinal study design. Methods: Participants were adolescent cohort of 1,971 middle school students participating in 2013 and 2014 Korean Children and Youth Panel Survey conducted by National Youth Policy Institute. Data were analyzed by Pearson's Correlation and regression. Results: The major findings are as follows. First, self-esteem and self-resilience were positively related to each other and negatively related to depression and bullying victimization. Second, bullying victimization effected the level of depression of adolescents and self-esteem played a mediating role between bullying victimization and depression while self-resilience did not. Conclusion: The results suggest that emotional factors continue to play an important role in promoting psychological adjustment of victims of bullying. Therefore, interventions are more likely to be successful if they focus on emotional skills development of adolescents.

This study tested the possibility of applying the integrated social cognitive career theory for workers with disabilities to explore ways of predicting and enhancing their subjective well-being. It analyzed 952 adults who were employed for three years, among the workers who had participated in the Panel Survey of Employment for the Disabled from 2016 to 2018. The results showed that disability acceptance was positively related to occupational self-efficacy, job satisfaction, and life satisfaction with statistical significance, and that occupational self-efficacy had a partial mediating effect on the relationship between job satisfaction and disability acceptance. Moreover, both auto-regressive and cross-lagged effects between disability acceptance and job satisfaction were found to be statistically significant. These findings imply that disability acceptance and occupational self-efficacy can be regarded as important factors to increase the subjective well-being of workers with disabilities.

This study examined the longitudinal relationship between paternal depressive symptoms and maternal depressive symptoms simultaneously. This study also identified the interplay of paternal and maternal depressive symptoms for predicting elementary children's language development, their problem behaviors and their school adjustment. Using the data from the Panel Study on Korean Children for the 4th-8th years (2011~2015 year), this study used the Latent Growth Curve Model, which is helpful for examining longitudinal relationship differences among variables. The sample subjects were 1,754 parents and children. The results are as follows. The initial level of paternal depressive symptoms had a positive impact on the rate of change in maternal depressive symptoms. The initial level of maternal depressive symptoms had a negative impact on the rate of change in maternal depressive symptoms. Mothers' depressive symptoms showed not only the mothers' own depression problem. but also the self-effect and counterpart effect of depression on the fathers' depression problem. The rate of change in maternal depressive symptom mediated the relation between the initial level of parental depressive symptoms and children's receptive language, internalizing/externalizing problems, and school adjustment. Therefore, depression prevention and intervention programs for both fathers and mothers are needed for the healthy development and school adaptation of school-age children.

This study examined the longitudinal effects of media usage by early school-age children and of maternal parenting stress on children's school adjustment. The study focused on the mediating effect of executive function difficulty. Longitudinal data to examine the hypothetical model were drawn from the eighth (2015) through tenth (2017) waves of the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE). A total of 581 children (293 boys and 288 girls) and their mothers were included. Confirmatory factor analysis, structural equation model, and bootstrapping analysis were applied using SPSS 25.0 and Amos 26.0. The results are as follows. First, no significant correlation was found between early school-age children's media usage and maternal parenting stress. Second, neither media usage by early school-age children nor maternal parenting stress were found to directly affect children's school adjustment. Third, media usage by early school-age children and maternal parenting stress were shown to indirectly affect children's school adjustment via executive function difficulties. In other words, higher levels of media usage by early school-age children and maternal parenting stress during the first grade lead to greater executive function difficulties after a year, which, in turn, lead to a lower level of school adjustment in the third grade. This study indicates the need to develop practical support for the psychological wellbeing of mothers while they are performing their role as a parent and for children in maintaining suitable levels of media usage during early childhood.

This study aimed to propose implications for mental health and cultural arts education, in which certain factors can contribute to acquiring and improving creativity in adolescents to cultivate the creative human resources required in future society. The study used panel data from the Korean Education Longitudinal Study provided by the Korea Educational Development Institute. First, we analyzed the correlation between mental health and creativity and then examined mediation and serial mediation effects of the frequency of participation in cultural activities and the experience of them between two factors. The results showed that mental health was significantly positively correlated with creativity. Additionally, the frequency of participation in cultural activities and their experience were confirmed to have partial mediating effects. In other words, sound mental health factors such as comfort, enjoyment and happiness, cultural education, and cultural activities were found to have positive effects on creativity in adolescents. To develop creativity in adolescents, this study suggests the following challenges: (1) enhancing positive mental health, (2) increasing participation in cultural and artistic activities, (3) actively developing education programs for the cultural arts on community and educational sites, and (4) using and promoting local cultural and artistic education programs. These are expected to make an important contribution to fostering talented adolescents with creativity and convergence.

This study examined the longitudinal effect of preschool children's media exposure and maternal depression on first-grade children's school adjustment and the mediating effect of attention problem. Longitudinal data from the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE) was used to examine this hypothetical model. The subjects of the study included 2,150 children (1,091 boys and 1,059 girls) and their mothers across 2013 (5 yrs.) through 2015 (7 yrs.). The Structural Equation Model (SEM) was estimated using SPSS 25.0 and Amos 25. The results of this study were as follows. First, higher level of preschool children's media exposure and maternal depression were related to higher attention problems after a year and lower level of children's school adjustment during first-grade. Second, preschool children's media exposure and maternal depression had an indirect effect on first-grade children's school adjustment via attention problem. The results of this study will provide supporting evidence to many educators and parents for the implementation of effective practices for first-grade children to enhance their school adjustment. Furthermore, this study emphasizes the importance of maternal psychological wellbeing and the risk of indiscriminate media exposure during early childhood on first-grade's school adjustment.

This study examined the longitudinal effects of appearance satisfaction and Korean language skills on the self-esteem and school adjustment of multicultural adolescents. The study used data from 1,151 multicultural adolescents from the $3^{rd}$, $4^{th}$, and $5^{th}$ waves of the Multicultural Adolescents Panel Study (MAPS). Data were analyzed by means of descriptive statistics, Cronbach's alpha, correlation, and structural equation modeling. The results are as follows. First, appearance satisfaction and Korean language skills at grade 6 significantly predicted higher self-esteem at grade 7. Second, there was a significant influence of high levels of self-esteem at grade 7 on positive school adjustment of grade 8. Last, the self-esteem at grade 7 had a significant mediating effect in the relationship between appearance satisfaction and Korean language skills at grade 6 and school adjustment at grade 8. The results of this study highlighted the importance of self-esteem as a mediating factor in the connection between appearance satisfaction and Korean language skills as well as the level of school adjustment. This provides supporting evidence to many educators and parents for the implementation of effective support practices for multicultural adolescents to enhance their school adjustment. Other related implications of these findings and suggestions for future research are also discussed.

The primary goal of the current study was to investigate the longitudinal relationship between household income, main caregiver depression, and youth aggression from the interactionist perspective. The data were derived by combining the 2006, 2009 and 2012 survey waves from the Korean Welfare Panel Study. This data set covered the full span of adolescence from elementary to high school. The study utilized 561 families as the final sample and conducted autoregressive cross-lagged analysis. As a result, the early income status, main caregiver depression and youth aggression were likely maintained over time. Second, the results provided support for a reciprocal relationship between income and main caregiver depression. On the other hand, the reciprocal relationship between main caregiver depression and youth aggression was not found in the current study. Finally, the mediating effect of main caregiver depression between income and youth aggression was not found in the present study. In conclusion, the results of this study support the interactionist model in that the association between family income and main caregiver depression involves reciprocity and mutual influence across time. These findings have major implications for policy and interventions in regards to low-income families.

The aim of this study is to examine the relationships between social support and child behavior problems and cognitive development in low income female-headed families. Informed by the stress-coping theory, family process model, and theoretical perspectives related to social support, this study estimates both direct and indirect effects of social support on child behavior problems and cognitive development. In particular, we focus on how the relationship between child outcomes and social support is mediated by mothers' parenting stress. The first three waves of longitudinal data from a subsample of 1,315 single and non-cohabiting low-income mothers in the Fragile Families and Child Wellbeing Study were utilized in this study. Results suggest that social support is directly associated with child behavior problems and also indirectly associated with child behavior problems mediated by mothers' parenting stress. Social support did not have a direct effect on children's cognitive development but rather had an indirect effect, which was mediated by mothers' parenting stress. The policy and practice implications of these findings are discussed.
