The purpose of this study was to examine the effects of parental abuse and neglect, as well as that of children's peer attachment, on mobile phone dependency. Data were obtained from the Korean Child-Youth Panel Survey (KCYPS), and the participants were 1,892 (909 boys, 983 girls) elementary students (5th graders) who had a mobile phone. To measure the variables, this study used such scales as the parental abuse and neglect scale, peer attachment scale, and mobile phone dependency scale. The data were analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling analysis. The results of the study were as follows: First, parental abuse and neglect had direct negative effects on children's peer attachment; that is, the more parental abuse and neglect, the less children's peer attachment. Second, parental abuse and neglect had direct positive effects on mobile phone dependency; that is, the more parental abuse and neglect, the greater children's mobile phone dependency. However, children's peer attachment did not directly affect mobile phone dependency; that is, children's peer attachment did not have a mediating effect between parental abuse and neglect, and mobile phone dependency. In conclusion, parental abuse and neglect influence children's peer attachment and mobile phone dependency. Thus this study showed that parental abuse and neglect, rather than children's peer attachment, affect children's mobile phone dependency.

Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

This study aimed to demonstrate the complex and structural relationships between (a) the purposes of using mobile phones, and (b) the levels of mobile phone dependency and depressive symptoms among elementary school students. We analyzed data from the 3rd Korean Children and Youth Panel Survey using structural modeling. Results showed the level of mobile phone usage for contacting family members negatively affected the mobile phone dependency. However, the levels of mobile phone usage for contacting friends and personal entertainment positively influenced the mobile phone dependency. Mobile phone dependency positively affected depressive symptoms. Mobile phone dependency partially mediated the relationship between the level of mobile phone usage for contacting family members and depressive symptoms. Mobile phone dependency fully mediated two relationships: (1) between the level of mobile phone usage for contacting friends and depressive symptoms and (2) between the level of mobile phone usage for personal entertainment and depressive symptoms.

The purpose of the present study was to test the impact of depression on mobile phone dependency among elementary school students, to test the mediating effect of self-esteem between depression and mobile phone dependency, and to draw out theoretical and practical implications in terms of preventing or reducing mobile phone dependency. Based on previous studies, a longitudinal research model between the aforementioned three variables has been identified. The present study analyzed the 4th, 5th, and 6th wave data from Korea Children and Youth Panel Study 2010 (KCYPS 2010). The major results were as follows. First, depression could have a significant negative effect on self-esteem. Second, self-esteem could have a significant negative effect on mobile phone dependency. Third, the influence of depression on mobile phone dependency was not significant. Fourth, gender could be a significant moderating variable between depression and self-esteem. Finally, a number of implications of these findings were also discussed.

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 purpose of this study was to examine the longitudinal relationships between Korean adolescents'mobile phone dependency, trajectories of depression, and self-regulated learning abilities. To achieve these goals, structural equation modeling analysis was conducted, using the 3rd, 5th and 7th wave of the data on 4th graders taken from the Korean Children and Youth Panel Survey. The results can be summarized as follows. First, growth-curve longitudinal analysis indicates that depression in 6th through 10th grade has increased. Second, mobile phone dependency among adolescents at 6th grade has a significant effect on both the initial value and the rate of change in depression. Also, the initial value and the rate of change in depression have significant relationships with mobile phone dependency at 10th grade. Moreover, both increased levels of mobile phone dependency and the rate of change in depression significantly influence adolescents'self-regulated learning abilities at 10th grade. Based on a longitudinal data set, these findings demonstrate the causal relationships between Korean adolescents'trajectories of depression and their mobile phone dependency. The findings also provide a comprehensive framework with implications for adolescents'development through an understanding of the relationships between adolescents'depression and mobile phone dependency, which impact their self-regulated learning abilities.

Prevalent usage of mobile devices among consumers has been well recognized and this is especially imperative among young adult consumers. The mobile phone became the gateway of their communication, media consumption, retail transaction, education, and (virtual) social life. However, there is little empirical research explaining the dynamics behind the psychological underpinning of young adult consumers, specifically Generation Y, to understand their usages and dependency on mobile phones. This study, therefore, aims to unveil antecedents and consequences of Gen Y consumers' mobile phone dependency from a media psychological perspective. We developed a conceptual model based on theory of self-monitoring (Snyder 1974, 1987), extended self-concept (Belk, 1988), and media dependency theory (Ball-Rokeach & Defluer, 1976). Four hundred ninety-eight students in the U.S. provided usable responses to our pencil-and-paper survey. Causal modeling analysis results demonstrated that both ability to modify one's behavior and sensitivity to cues for social appropriate behavior dimensions of the self-monitoring tendency positively predicted one's level of fashion involvement, which in turn positively predicted his/her mobile phone dependency. Individual's mobile phone dependency, fashion involvement and self-monitoring's ability dimension exhibited positive and direct impact on one's perception of the salience of mobile phone case product attributes. Based on the findings, we provided pragmatic and theoretical implications for the industry and academia.

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 examined the role of after-school caregiver absence in the relationship between school adjustment and mobile phone dependency during early adolescence. Sixth grade students(N=1,863) from the nationally representative Korea Child and Youth Panel Study were analyzed using moderated multiple regression models. The results showed that higher school adjustment may be effective in reducing youth mobile phone dependency. There was also a significant interaction effect between school adjustment and high caregiver absence, indicating that the protective role of school adjustment concerning mobile phone dependency may be less effective among youth of highest risk. Policy implications of the results are also discussed.
