Purpose: Internet is one of the essential tools in South Korean adolescent life. Recently, researchers suggest that Internet use is positively associated with teens' mental health problems such as depression and suicide. Thus, this study explored a relationship between Internet use and suicide ideation among South Korean adolescents. Methods:　Secondary data, the three-wave Korean Youth Panel Survey, were analyzed. First, in terms of the levels of Internet use and suicidal ideation, t-test was used for examining a gender difference, and Analysis of Variance were used for examining differences across three points in time(waves 2 - 4). Second, logistic analysis was performed to examine the significant association between Internet use and suicide ideation after controlling for the other factors' effects. In this analysis, Fixed Effect Regression Method(FERM) was incorporated as well. FERM was useful in adjusting for the effects of time-invariant factors even without measuring them. As a result, it was possible to obtain more accurate findings. Results: Adolescent depression was an important factor influencing the association between Internet use and suicide ideation. After controlling for the effect of depression, the relationship between Internet use and suicide ideation was no longer statistically significant. Conclusion:　As a proxy to identify teens who are obsessed with suicide ideation, levels of Internet use do not seem useful. Instead, it is necessary to examine teens' access to websites related to suicide.

Objectives: This study investigated the relationship between adolescents' suicidal ideation and their physical health conditions to contribute to lower suicide rates among adolescents. Methods: Secondary analysis of 2108 high school students of $10^{th}$ grade was conducted using the Korean Child and Youth Panel survey in 2013. The association between suicidal ideation and socio-demographic and health characteristics were analyzed using Chi-square tests and regression models. Results: Adolescents' physical health conditions were significantly related to suicidal ideation. In particular, rhinitis and various symptoms such as feeling feverish, low appetite, feeling of nausea, stomachache while studying, and sleeping problem showed statistically significant relationships with suicidal ideation (P < .05). Furthermore, the higher frequency of diseases and body symptoms increases the rate of suicidal ideation. Considering socio-economic characteristics, family structure was also important. Conclusions: Physical health condition is a major contributor to adolescent's suicidal ideation. results suggest that improving social support system for adolescents' physical health conditions across family and school may be important in suicide prevention efforts.

Objective: The purpose of this study was to identify the longitudinal relationship between child maltreatment and adolescent suicidal ideation. Several studies suggest that child maltreatment is associated with adolescent suicidal ideation. However, these studies have not focused on the duration of child maltreatment. Methods: Participants were 420 adolescents (52.6% male; 47.4% female) involved in the Korea Welfare Panel Study. Data were collected via youth self-report in 2006, 2009, and 2012. A self-report assessment of children and youths' experiences of physical, emotional, or neglect had been surveyed longitudinally. Questionnaires on adolescent suicidal ideation were answered in 2012. A growth mixture model and multiple regression were conducted using Mplus 5.21. Results: The study results showed that 93.5% of the children had experienced no maltreatment; 6.5% had experienced increasing maltreatment longitudinally. The trajectory of increasing maltreatment was positively associated with adolescent suicidal ideation. Conclusion: These results show that children suffering from chronic maltreatment are subject to a high risk of suicide and therefore require continuous supervision and management.

Purpose: The purpose of the study is to examine the factors that influence Korean adolescents' depression and suicidal ideation from individual, social and environmental perspectives by gender. The study used the date of the 2015 Korea Youth Risk Behavior Web-based Survey and the subjects were 68,043 middle and high school students. The levels of depression and suicidal ideation were the dependent variables and the factors influencing the dependent variables included 11 individual factors, 3 social factors and 7 environmental factors. The data were analyzed using odds ratios (OR) from multi-variable logistic regression analysis. As a result, the most significant individual factors that influenced both depression and suicidal ideation were stress and subjective happiness both in boy and girls, the most significant social factor was participation in violence treatment programs, and the most significant environmental factors were economic status, father's educational level, and whether or not they lived with their family. Therefore, programs and policies to improve adolescents' mental health should be developed considering individual, social, and environmental factors.

Quantitative survey research was conducted with 1735 students attending primary, middle and high school to identify the following the key results. First, adolescent's academic stress directly influenced their suicidal ideation and its' effect was indirectly mediated by the subjects's self-esteem. Second, the relationship between the experience of school bullying victim and suicidal ideation was partly mediated by self-esteem. In other words, the severer academic stress in youth and the experience of bullying victim were, the higher suicidal ideation were; however, the adolescent's high self-esteem played a mediating role in lowering their suicidal ideation by increasing the ability of overcoming difficulties and risks.

Objective: The purpose of this study was to confirm if there are gender differences in influences of parental support, control, and school life adjustment on suicidal ideation of adolescents and to examine the mediating effect of depression on the influences of independent variables on their suicidal ideation. Methods: This study comprised a total of 671 students in seventh and eighth grades in Seoul and Gyeonggi-do. The data were analyzed for frequency, average, and standard deviation, using the t-test, Pearson's correlation analysis, stepwise regression analysis, hierarchical multiple regression analysis, and the Sobel test. Results and Conclusion: First, significant differences among adolescents' gender were shown in fathers' psychological control, mothers' behavior control, and suicidal ideation. Second, in the case of male adolescents, all independent variables were found to have a full mediating effect on their suicidal ideation. Meanwhile, in the case of female adolescents, independent variables except for mothers' psychological control were found to have a full mediating effect on their suicidal ideation. Mothers' psychological control was found to have a partial mediating effect on suicidal ideation of adolescents for both genders.

This study examined the influences of both peer and parent-child relationships on suicidal ideation in adolescents with a focus on interpersonal relationships in adolescence that can act as risks as well as protective factors for youth suicide. This study analyzed 5,440 middle and high school students drawn from data, the seventh Happy Planet Index of children-adolescent in Korea, and conducted a series of logistic regressions. The results are as follows. First, both direct and indirect involvement in the school violence affects suicidal ideation as a risk factor in peer relationships. However, the quality and quantity of close friends of adolescents do not represent a protective role against suicidal ideation insofar as they are exposed to school violence. Second, adolescents who live apart from one of their parents are vulnerable to suicidal ideation than those who live with two parents. Third, very poor parent-child relationships in adolescence are not necessarily associated with suicidal ideation in adolescents. Fourth, shared time or activities between parents and adolescents in terms of family meal times are more likely to reduce suicidal ideation in adolescents than the emotional characteristics (trustworthiness or a close relationship) of parents and adolescents. The findings provide implications that frequent contact and shared activities in terms of family dining may contribute to the prevention of adolescent suicide.
