This study was to investigate the moderating effect of the protective factors in the relationship between impulsivity and suicide behavior of elementary school students. This study surveyed total 573 elementary school students located in Seoul. They completed survey questionnaires of impulsivity, suicide behavior and protective factors. Collected data was examined using correlation analyses and hierarchical multiple regression analyses. First, a total of 29(5.1%) students reported suicide plan, 17(3.0%) students reported suicide attempts and the rate of suicide behavior was 7.1%(n=41). Second, there was a negative relationship between impulsivity and protective factors and a positive relationship between impulsivity and suicide behavior. Also, it was found that the protective factors(individual factor, family factor, peer factor, school factor) moderated the relationship between impulsivity and suicide behavior of elementary school students. The implications and limitations of this study were discussed.

The purpose of this study was to identify the mediated moderating effect of explosive behavior through gender between negative emotion and suicidal ideation. It was conducted to measure depression, anxiety, explosive behavior and suicidal ideation from 644(322 male, 322 female) university students. The mediated moderating effect was analyzed through hierarchical regression analysis and path analysis. And the results of simple slope test were presented graphically. As a result of analysis, first, there were positive relationship among negative emotion, explosive behavior and suicidal ideation. Second, gender had significant moderating effect within the relationship of negative emotion and suicidal ideation. Third, explosive behavior had significant mediating effect within the relationship of negative emotion and suicidal ideation. Forth, gender had significant moderating effect within the relationship of explosive behavior and suicidal ideation. Implications of these results were explored in relation to the importance of negative emotion and explosive behavior that could be taken to improve suicidal ideation according to gender. In addition, this implication and suggestions for future research are provided.

Objectives: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. Methods: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. Results: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. Conclusions: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

There are less studies on the adult suicide even though it's steep increase and negative effect on person itself, family and society. The purpose of the present study was to investigate factors that influence on the adult suicide and to categorize it. Using a case-study approach, a total of 61 cases were analyzed. Specifically, on the basis of the stress-vulnerability model, I scrutinized vulnerability factors(classified personal, family-environment, and social-environment factors) and precipitating events(classified personal, interpersonal events) influencing on the adult suicide. As the results of this study, adult suicide classified into 3 types, that is, 'risk type suicide', 'event-response type suicide', 'complex type'. And then I discussed the characteristics of the suicidal types and the method for reduction of adult suicide.

The purpose of the study was to identify the factors on Gatekeeper behavior of adolescents for suicide prevention. The participants were five high school students from D metropolitan city. The collected data were analysed using t-test, ANOVA, Multiple regression with SPSS 21.0 program. In the results of the study, Gatekeeper behavior showed significant difference by gender(t=2.85, p=.005), type of school(t=-2.81, p=.006), experience of significant others' suicide(t=-2.09, p=.038). Gatekeeper behavior had a positive relationship with the perception toward suicide prevention(r=.23, p=.006) and the knowledge about suicide prevention(r=.42, p<.001). In regression analysis, significant influencing factors on Gatekeeper behavior were the perception toward suicide prevention (${\beta}=.20$, p=.006) and the knowledge about suicide prevention(${\beta}=.35$, p<.001), and these variables showed 24.3% of variance. Therefore, it need to develop the intervention for improving positive perception and active knowledge about suicide prevention in adolescents. In addition, future study to identify various predictable variables is needed.

The goals of the study were to examine if and how exposure to suicidal factors in social relationships affects suicidal ideation and behaviors and also analyze how family factors are associated with suicidal ideation and behavior. Data drawn from Korean General Social Survey(KGSS) collected in 2009 were analyzed. The findings show that exposure to the suicidal factors have statistically significant effects on suicidal ideation and behaviors. In the findings, respondents who have experiences of which socially close persons have suicidal ideation or completed suicide are more likely to have suicidal ideation and suicidal plan even in the models for which demographic factors and depressive symptoms are controlled. Also, family factors have significant effects on suicidal ideation and suicidal behaviors. Family stress increases suicidal ideation and behaviors whereas expectation on family support reduces the likelihood of having suicidal ideation and behaviors. This study shows that there might be possibility of behavioral contagion in terms of suicide through social connections and family has both positive and negative aspects on suicidal ideation and behaviors. Our study suggests policy implications for people who were exposure to suicide.

This study is to examine moderating effects of income and mediating effects of health related quality of life in the relationship between depression experience and suicidal behavior among menopausal middle-aged women in Korea. This study employed 1,182 middle-aged women aged 40 to 60 of the third year (2015) data from the 6th Korean National Health and Nutrition Examination Survey(KNHANES VI). The results are that first, depression experience were significantly associated with suicidal behavior. Secondly, health related quality of life appeared to mediate the relationship between depression experience and suicidal behavior. Thirdly, income was significantly moderated the relationship between depression experience and suicidal behavior in relatively low income group below average income after controlling for mediating effects of health related quality of life. These results showed that there is a need to enhance health policy for mental health care in middle-aged women and to expand intervention program for improvement of health related quality of life, and especially, intervention for improving mental health of low-income group.
