This study examined the mediating effect of depression on the relationship between over-control parenting styles and mobile phone dependency among children. The 5th-year longitudinal data from the Korean Children & Youth Panel Survey (KCYPS) were collected from 4th grade elementary school students. The data were analyzed by the structural equation modeling and bootstrapping. The results of this study were as follows. First, there is a positive path from over-control parenting styles to depression, from depression to mobile phone dependency, and from over-control parenting styles to mobile phone dependency. Second, depression had a mediating effect on the association between over-control parenting styles and mobile phone dependency. Based on these results, more study of elementary school students' reliance on cell phones is needed.

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 purpose of this study was to classify the elementary school students to latent groups according to the type of mobile phone usage and to verify the relationship with mobile phone dependency. The latent profile analysis was conducted using the first grade panel data of the elementary school in the Korea Children 's Youth Panel in 2016. The results found 3 latent classes of mobile phone usage: family and friend concentration (Type1), family concentration low level (Type2) and essential (Type3). The results of multiple regression analysis for verifying the relationship between mobile phone use type and mobile phone dependency showed a significant effect. The Type 2 showed more dependency than the Type 1, and the Type 1 showed more dependency than the Type 3. These findings provided basis for the guideline of mobile phones use and for proper intervention to prevent mobile phone dependency for elementary school students.

The purpose of the present study was to examine the causal relationship between aggression and mobile phone dependency among high school students and to test the mediating effect of self-esteem, and to draw out implications in order to encourage proper use of mobile phone. In this paper, we proposed a research model between aggression, self-esteem and mobile phone dependency. The present study analyzed the fourth, fifth, and sixth wave data from KCYPS 2010, using the structural equation modeling. The primary results were as follows. First, the effect of high school students' aggression on mobile phone dependency was not significant. Second, high school students' aggression had a significantly negative effect on self-esteem. Third, high school students' self-esteem had a significantly positive effect on mobile phone dependency. Fourth, high school students' self-esteem could be a significant mediator between aggression and mobile phone dependency. In conclusion, theoretical and practical suggestions were discussed in order to solve the problem of adolescents' mobile phone dependency.

This study aimed to discriminate the groups clustered by mobile phone dependency and use type and to explore the quality of parent child-rearing attitudes and peer relationships predicting the types of groups. The subjects were the 688 fourth-grade students participating in the Korea Child Youth Panel Surveys. The data were analyzed with descriptive statistics, cluster analysis, One-way ANOVA and multinominal logistic regressions. The main results of this study were as follows. Firstly, as the result of cluster analysis inputting the mobile phone dependency and use type, the four clustered groups were produced. Secondly, the quality of parent child-rearing attitudes and peer relationships discriminating the four groups were parents' supervision, over-involvement, love, senses of non-alienation from peers and communicating with them. Therefore, this study suggested the parent education and peer-relationship improving program to form children's good habits of mobile phone use.

A mobile phone usage survey was administered to a nationwide sample of 3,617 adolescents. Major motivations of mobile phone usage were mobility/real-time connection, show off, information acquisition, entertainment, dialogue, schedule management, and advice. Maintenance of social relationship with the peer group was most important in mobile phone use. Motivations influenced mobile phone dependency : show off had the strongest influence on anxiety/paranoia followed by dialogue, entertainment, mobility/real-time connection. Without their phones, fashion-oriented adolescents showed mobile phone dependency and anxiety. Stronger dialogue and entertainment motivations were associated with weaker real time connection motivation and stronger paranoia symptoms. Mobile phone dependent adolescents had lower grades, showed lack of attention, had little dialogue with their parents and showed withdrawal from the peer group.

The study explores how academic strain, unhappiness, and mobile phone dependency among adolescents have changed over time. And we conducted the longitudinal and complex analysis on the influence of academic strain on unhappiness and mobile phone dependency in order to search the ways to prevent a vicious circle among them. We used general strain theory as a conceptual research frame and analysed the data of 1,589 respondents of the 2nd~4th Korean Children and Youth Panel with latent growth modeling. It was found that the levels of academic strain, unhappiness, and mobile phone dependency among adolescents were linearly increased across time. Academic strain initial status positively affected unhappiness initial status and both the initial status and change rate of mobile phone dependency. The change rate of unhappiness positively affected that of mobile phone dependency. Academic strain change rate positively influenced that of mobile phone dependency mediated by unhappiness change rate. We provided useful implications to academic activities, negative emotions, and mobile phone dependency for adolescents and suggested future studies about reasons of the changes of those variables.

The purpose of this study was to examine the mediating effects of mobile phone dependency in the relationship between parenting attitude and juvenile delinquency. This study used the secondary data from the $1^{st}$, $2^{nd}$ and $3^{rd}$ waves of the Korean Children and Youth Panel Survey(2010, KCYPS). The data of 2,086 middle school students were analyzed by utilizing Structural Equation Model(SEM). The results are as follows. First, positive and negative parenting attitudes had no direct effects on juvenile delinquency, while positive parenting attitudes had significantly decreased adolescents' mobile phone dependency. In addition, negative parenting attitudes had positive effects on adolescents' mobile phone delinquency. Second, mobile phone dependency was fully mediated by parenting attitudes and juvenile delinquency. On the basis of these results of study, policy and practice implications were discussed to reduce juvenile delinquency by improving parenting attitudes.

The aim of this study is to search for a direction to reduce adolescents' mobile phone dependency. The fourth data for 4th graders who were 1,972 of 7th from the 2013 Korea Children & Youth Panel Survey were used. SPSS 21.0 was used. In addition, the mediating effects of ego-resiliency and gender-moderating effects between positive parenting attitude and mobile phone dependency were analyzed through descriptive statistics, data analysis, correlation analysis and multiple regression analysis. The results found the followings: Positive parenting attitude increased ego-resiliency while lowering mobile phone dependency. Ego-resiliency had a negative influence on mobile phone dependency and mediating effects between the two variables. Gender had a moderating effect between two variables. Based on the above results, this study suggested a direction to cope with the problems which can result from the excessive use of mobile phone for both parents and their children.
