Purpose. The purposes of this study were 1) to examine the differences in suicidal ideation and psychological variables by gender, 2) compare the contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation, and 3) identify the most important predictors of suicidal ideation for male adolescents and female adolescents. Methods. The subjects consisted of 271 male adolescents and 230 female adolescents. Data were collected through self-report questionnaires, which were constructed to include SSI-C, DEP subscale of the SCL-90-R, PACI, and SWLS. The data were analyzed by the SPSS/WIN program. Results. Suicidal ideation differed by gender. Depression and family communication differed by gender. The unique contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation differed between male adolescents and female adolescents. The significant predictors of suicidal ideation for male adolescents were life satisfaction, depression, and family communication, explaining $28\%$ of the variance in suicidal ideation. The significant predictors of suicidal ideation for female adolescents were depression, smoking, and life satisfaction, explaining $38\%$ of the variance in suicidal ideation. Conclusion. The findings of this study suggest that the approach to effective suicide prevention program for adolescents should consider gender differences.

The purpose of this study was to identify the moderating effect of self-control in the relationship between online game addiction and depression among adolescents exposed to the online game environment. A total of 378 respondents who are high school students in K Metropolitan City were selected for the current study. The process macro program developed by Andrew F. Hayes was used to analyze for the moderating effect and the SPSS 25.0 program was used for frequency, descriptive statistics, and correlation analysis. The results showed that online game addiction in adolescents had a significant positive effect on depression and self-control had a negative effect on depression, and self-control had a moderating effect on the relationship between online game addiction and depression in adolescents. The higher the online game addiction among adolescents, the higher the depression, and the influence depends on the level of self-control.

Objectives : This study aimed to identify factors of adolescents' cell-phone dependency using Agnew's General Strain Theory (GST) and the perspective of adolescents' micro-systems. A second aim was to verify the moderating effect of self-esteem. Methods : In total, 2,046 students who participated in a study on KCTPS mid. 1 panel 3 Wave by the National Youth Policy Institute were examined in this research. Data were analyzed through descriptive statistics, factor analysis, reliability tests, and hierarchical linear regression using SPSS Ver. 22.0. Results : The strain factors had a positive effect on adolescents' depression, and depression had a positive effect on cell-phone dependency. In addition, self-esteem had a negative moderating effect between depression and cell-phone dependency. Conclusions : Factors of cell-phone dependency were identified. The findings of the study indicate that an intervention is required to lower strain and depression and to enhance self-esteem among adolescents.

This study examines the relationships between dietary self-efficacy, social support, depression, and weight-control behavior of children and adolescents. A total of 593 students (280 children and 313 adolescents) from schools in Seoul, Gyeonggi-do, Jeollabuk-do, and Daegu were surveyed using scales for dietary self-efficacy, social support, depression, and weight-control behavior. The data were analyzed through a frequency analysis, means and standard deviations, a t-test, a one-way ANOVA, the Tukey test, the Pearson's correlation, and a stepwise multiple regression analysis. According to the results, weight-control behavior was more likely in girls than boys, high-school students than elementary-school students, and obese/overweight students than normal/underweight students. The factors influencing children's weight-control behavior were general eating habits, the BMI, depression, food choice, and family support, in that order, and those influencing adolescents' weight-control behavior were general eating habits, gender, and the BMI, in that order. These results are expected to be useful as basic data for developing weight-control programs for children and adolescents.

Purpose: The purpose of this study was to examine the relationship between sleep duration, quality of sleep and depression, and to identify the factors associated with depression in middle school students. Methods: This study used a cross-sectional design with secondary data, middle school student panel data from the Korean Children and Youth Panel Survey (2018), and data from a total of 2,590 students was used for analysis. For the statistical analysis, t-test, ANOVA, and hierarchical multiple regression were performed using SPSS ver. 26. Results: The mean depression score in adolescents was 17.99±6.38. Depression had significant differences according to sleep duration and quality. Adolescents with less than eight hours of sleep showed the highest depression, and poor sleepers showed higher depression scores than good sleepers. Gender, school achievement, school satisfaction, economic status, and exercise time were found to significantly relate to depression. After controlling for general characteristics, depression explained 17.2% of the variance in quality of sleep (β=-.15, p<.001) and sleep duration (β=-.04, p=.022). Conclusion: These findings indicate that it is necessary to develop intervention strategies to enhance the quality of sleep and appropriate sleep duration for preventing depression in adolescents.

The purpose of the present study was to develop a structural model, of which the effect of parents' psychological control, depressive dispositions, and depression upon the self-esteem of adolescents. The participants were 458 adolescents recruited from high schools and universities (M age = 17.4 yrs; SD = 1.75) in Seoul and its vicinity. Data were collected through self-reporting questionnaires for adolescents. Firstly, we estimated the hypothesized meditation model which includes paths from parents' psychological to self-esteem through adolescents' depressive experiences and depression. Structural Equation Modeling analysis using AMOS revealed that the hypothesized mediation model yielded an acceptable model fit and all hypothesized path coefficients were found to be significant. Specifically, it indicated that the more parents try to exert psychological control over their children, the more depressive experiences adolescents have and in turn, they had a greater tendency towards becoming depressed and having lower self esteem. It was also found that neither gender difference nor age difference existed in the structural model.
