This study attempted to test the path model that can predict Korean adult suicidal ideation. The subjects were 459 adults aged between 19 and 64 who agreed to this study among quota sampled by the population, sex, and region of the metropolitan city. The path model of collected data was estimated using SPSS 24.0 program and AMOS 22.0. The results of the bias-corrected percentile method for verifying the significance of the mediator effect of the final model showed that suicidal attitude, depression, and stress were found to be mediating effects of health status on suicidal ideation. Suicide attitude and stress were found to mediate the effects of health status on depression. And the effect of drinking on depression was mediated by stress. This result is expected to be used as a practical basis for the development of suicide prevention and intervention programs for adults in the future.

Purpose: This study was conducted to investigate the correlation between health status, health-promoting behavior, self-esteem and suicidal ideation among the elderly. Method: Subjects consisted of 115 elderly persons. Data were collected from January to March 2013, and were analyzed using descriptive statistics, a t-test, ANOVA, Pearson's correlation analysis. Results: The mean scores for health status ($2.41{\pm}.68$), health-promoting behavior ($2.38{\pm}.43$), and self-esteem ($2.87{\pm}.69$) among the elderly fell in the average range, whereas scores for suicidal ideation ($.48{\pm}.36$) among the elderly fell in the below average range. Health status differed significantly according to age, educational level and economic status. Health-promoting behavior did not differ significantly based on these general characteristics. Self-esteem differed significantly according to age, job, and number of people living in the household. Suicidal ideation differed significantly based on age, educational level, and economic status. Significant correlations were found between health status, health-promoting behavior, self-esteem, and suicidal ideation. Conclusion: These findings indicate that perceived health status, health-promoting behavior, and self-esteem may be factors that need to be considered in order to decrease the prevalence of suicidal ideation among the elderly. These results can be used to develop a suicide prevention program for the elderly.

Purpose The purpose of this study is to develop a prediction model and decision rules for the elderly's suicidal ideation based on the Korean Welfare Panel survey data. By utilizing this data, we obtained many decision rules to predict the elderly's suicide ideation. Design/methodology/approach This study used classification analysis to derive decision rules to predict on the basis of decision tree technique. Weka 3.8 is used as the data mining tool in this study. The decision tree algorithm uses J48, also known as C4.5. In addition, 66.6% of the total data was divided into learning data and verification data. We considered all possible variables based on previous studies in predicting suicidal ideation of the elderly. Finally, 99 variables including the target variable were used. Classification analysis was performed by introducing sampling technique through backward elimination and data balancing. Findings As a result, there were significant differences between the data sets. The selected data sets have different, various decision tree and several rules. Based on the decision tree method, we derived the rules for suicide prevention. The decision tree derives not only the rules for the suicidal ideation of the depressed group, but also the rules for the suicidal ideation of the non-depressed group. In addition, in developing the predictive model, the problem of over-fitting due to the data imbalance phenomenon was directly identified through the application of data balancing. We could conclude that it is necessary to balance the data on the target variables in order to perform the correct classification analysis without over-fitting. In addition, although data balancing is applied, it is shown that performance is not inferior in prediction rate when compared with a biased prediction model.

Objectives The aim of this study is to investigate the association between secondhand smoke (SHS) exposure and depressive symptoms among Korean adults. This study also explored the mediating role of self-rated health (SRH) and perceived usual stress (PUS) in the association between depressive symptoms, suicidal ideation and SHS exposure. Methods Data from the Korea National Health and Nutrition Examination Surveys (KNHANES) in 2014 and 2016 was analyzed for 10539 participants aged 19 years or older. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in the logistic regression analysis with adjustment for the potential confounding factors. We also adopted the mediation analysis method by Hayes and Preacher. Results After adjusting for the potential confounding factors, SHS at home and at public places were associated with depressive symptoms and suicidal ideation among non-smokers. After adjusting for the potential confounding factors, SHS at home and at public places was associated with depressive symptoms and suicidal ideation among non-smokers. Meanwhile SHS at workplaces was associated with depressive symptoms among former smokers and with suicidal ideation among current smokers. There was an additive effect of SHS on depressive symptoms only among non-smokers. SRH mediated the association between SHS and depressive symptoms and suicidal ideation among non-smokers. We did not observe any significant mediating effect of SRH nor PUS on the association between SHS and depressive symptoms among former and current smokers. Conclusions SHS may be associated with depressive symptoms and suicidal ideation in Korean adults. Our study elucidated how SHS interacted with depressive symptoms among non-smokers through the mediation by SRH.

This study was conducted to identify and compare the stressors and coping behaviors of high school students who experienced suicidal ideation vs those who do not. Method: The data were collected from 1,441 high school students living in the middle region of Korea. Researchers collected the data using Adolescent Stress Inventory and Adolescent Coping questionnare from February to May of 1999. Data were analyzed using X2, T-test. Result: A significant proportion (31.9%) of subjects had thought about suicide during the past 6 months, 297 girls (35.3%) and 163 boys (27.2%). Major stressors of subjects who experienced suicidal ideation were academic problems, conflicts between family members, and changes in sleeping or eating patterns. Conflicts with family members contributed to have suicidal ideation. There was no significant difference in helpful coping behaviors between the two groups. The group who experienced suicidal ideation had lower scores and fewer coping behaviors. Boys perceived more stressors and had fewer helpful coping behaviors than girls. Conclusion: It is necessary to develope school-based suicide prevention programs. Our findings suggest that the program should focus on problems related to studying and conflicts within the family.

Purpose: This study compares differences in stress, depression and suicidal ideation between nursing and students of other academic disciplines. Method: Nursing students (n=105) and students of other majors (n=148) were surveyed on the degree of personal stress, depression and suicidal ideation. Participants were recruited from three universities in cities S and C in Korea. Data were collected from May 1 to 20, 2013. Measurement tools were the Revised Life Stress Scale for College Students, Center for Epidemiological Studies-Depression Scale(CES-D), and Scale for Suicide Ideation(SSI). PASW Statistics 18 was used for descriptive analysis, homogeneity test(chi-square distribution) and ANCOVA. Results: The level of stress among nursing students was lower than that of students in other majors. Among the subcategories of stress, however, stress among nursing students arising from the student-faculty relationship was higher than that of their non-nursing counterparts. Conversely, differences in the prevalence of depression were notsignificant between nursing students and non-nursing students. Ultimately, it was revealed that there exists a strong correlation among stress, depression and suicidal idea for nursing students. Conclusion: Developing stress and depression management programs for nursing students is highly recommended.

Purpose: This study was done to identify the relationship of perceived health, coping strategies, dependency, suicidal ideation and depression widowed elders, and to identify predictors of depression in this population. Method: The research design for this study was a descriptive survey design using a convenience sampling. Data collection was done using self-questionnaire with 162 elders from welfare centers for senior citizens located in 3 cities, Seoul, Gangneung and Seosan. Pearson correlation coefficients and stepwise multiple regression with the SPSS Win 12.0 Program were used to analyze the data. Results: Depression had significant negative correlations with perceived health (r=-.525, p<.001), and coping strategies (r=-.253, p=.005) and positive correlations with dependency (r=.430, p<.001), and suicidal ideation (r=.473, p<.001). The explained variance for depression was 47.5%. Of the variables, perceived health (${\beta}=-.237$, p=.003), suicidal ideation (${\beta}=.398$, p<.001) and dependency (${\beta}=.341$, p<.001) significantly predicted the degree of depression. Conclusion: Findings from this study provide a comprehensive understanding of depression and related factors for widowed elders in Korea. However, further study with a larger random sample and more a detailed research design is necessary.
