This study attempted to derive high-risk groups of adolescent status delinquency(ASD) and to identify related factors. This study was conducted with 1,979 adolescents enrolled in the first year of high school, data from the 7th year of the 4th grade panel of the Korean Children and Youth Panel Survey. Classification and regression tree analysis method was used. The ASD group was 264, which was 13.3% of the total. The high-risk group for ASD is that is male who has a low perception of positive parenting style. Positive parenting style was found to be the most important influencing factor in ASD, followed by gender, emotional problems, relationship with teacher, and achievement value. In order to prevent ASD, it is necessary to develop a parenting education program and an intervention program specialized for male adolescents. In addition, interventions that comprehensively deal with emotional problems such as depression and social withdrawal are required, going beyond the previous interventions that focused on aggression. In particular, it has been found that relationship with teachers is the most important influencing factor in the school environment. Through education on the causes and consequences of ASD and training on counseling techniques, the promotion of relationships with teachers will act as a protective factor to prevent ASD.

This study compared a number of related variables according to children's stress types using the data mining method. The sample population was taken from the Korean Youth Panel Survey (KYPS) data (2688, sixth-grade elementary students). The results of the decision tree model revealed that : (1) Parental expectations in terms of study, life satisfaction, self-esteem, parental attachment, aggression, the spousal relationship, other cognition (one's own misdeeds), and study related worries were all related to parent stress. (2) Life satisfaction, study related worries, admitting one's own misdeeds, gender, other cognition (one's own misdeeds), aggression, the spousal relationship, and a sense of alienation in the school were all related to appearance stress. (3) Study related worries, parental expectations in terms of study, aggression, life satisfaction, self-esteem, parental attachment, satisfying parental expectations, parental attachment, and teacher attachment were all related to academic stress. (4) A sense of alienation in the school, mixing with peers in the school, aggression, self-esteem, other cognition (one's own misdeeds), study related worries, parental abuse, and life satisfaction were all significantly related to friend stress. These results suggested that children's diverse conditions should be considered according to the stress types if we are to understand and cope with these stress types more efficiently.

This study analyzed the structural relationship between peer communication experienced by ninth and twelfth graders who will undergo school transition, self-efficacy, depression, and life satisfaction. Through this, the study aimed to gain an understanding on ways to improve adolescents' life satisfaction from a life-span developmental perspective. It especially attempted to investigate whether a positive attitude toward oneself and negative emotions play a mediating role in the relationship between peer communication, which can provide environmental support for adolescents, and life satisfaction. To this end, the data of ninth grade (third year, 2012) and twelfth grade (sixth year, 2015) of the 7th Grade Panel of Korean Children and Youth Panel Survey (KCYPS) were used. The key results of study are as follows. First, peer communication, self-efficacy, and depression had a significant effect on life satisfaction directly and indirectly. Second, peer communication affected life satisfaction indirectly by the media of self-efficacy and depression. These findings suggested the importance of self-efficacy and depression in promoting adolescents' healthy and satisfactory lives that lead to adulthood. Also, the study suggested that the environmental background of adolescents in a transition can improve life satisfaction through training and counseling on cognitive and emotional factors.

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.

Objective: This study aimed to investigate the trajectories of mobile phone use with reference to its purposes, and to examine the effects of gender and interpersonal factors on the same in early adolescents. Methods: Latent growth modeling was used with a sample of 2,378 early adolescents from Grade 4 to 8. Data from the Korean Children and Youth Panel Survey conducted by the National Youth Policy Institute were used. Results: In boys and girls, overtime, the level of mobile phone use for communicating with family decreased, while that for communicating with friends increased. Level of mobile phone use for entertainment increased across time in boys; however, in girls, it increased from Grade 4 to 6 and decreased thereafter, until Grade 8. Gender was associated with the changes of mobile phone use according to the purpose of the same. Positive parenting, negative parenting, relationships with peers, and relationships with teachers predicted changes in mobile phone use for communicating with friends. Conclusion: These findings suggest that the processes involved in the trajectories of mobile phone use in early adolescence operate differently based on the purposes of the same.

Purpose: The purpose of this study was to find the factors influencing adolescents' adult media engagement. The study is based on Agnew's General Strain Theory (GST) and a micro-systemic perspective. Methods: The study examined 479 middle school freshmen who participated in the fourth wave of the Korean Children & Youth Panel Survey (KCYPS) conducted by National Youth Policy Institute. Data were analyzed through descriptive statistics, factor analysis, and reliability analysis using SPSS 22.0 Ver. Also, hypothesis testing was performed via covariance-based structure equation modeling (CB-SEM) using Amos 21.0 Ver. Results: Strain factors had positive effects on adolescent depression, and depression had a positive effect on adult media engagement. Also, cell-phone dependency had a positive mediation effect between depression and adult media engagement. Conclusion: The study's result identified the factors affecting adult media engagement. Therefore, we suggest intervention programs considering adolescents' strains, depression and cell-phone dependency to improve their health.

This study examines the effect of satisfaction with adolescent extracurricular activities on social withdrawal with a focus on the mediating effect of self-esteem and sense of community. We used data from the 3rd wave (2012) of the Korean Children and Youth Panel Survey (KCYPS) collected by the National Youth Policy Institute for path analysis. Participants were 1,139 first year middle school students who participated in adolescent extracurricular activities. First, the degree of satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem. Second, satisfaction with the adolescent extracurricular activities had an indirect effect on social withdrawal via a sense of community. Lastly, satisfaction with adolescent extracurricular activities had an indirect effect on social withdrawal via self-esteem and a sense of community. The research findings indicate that the level of social withdrawal is less when adolescents are satisfied with adolescent extracurricular activities and have a high level of self-esteem and sense of community. The results demonstrate that a satisfactory level of adolescent extracurricular activity would help adolescents decrease their social withdrawal by increasing the level of self-esteem and sense of community.
