This study aimed to identify demographic variables(gender, age group, occupation, living arrangement, economic level, respiratory and chronic diseases, previous medical history), COVID-19 variables(COVID-19 prevention behavior, frequent use of media to obtain COVID-19 information), and psychological behavioral variables(depression, anxiety, loneliness, and increased drinking). From February to March 2021, an online survey of adults was conducted, and a total of 1,434 data were used for analysis. 260 out of 1,434 people were confirmed to have suicide ideation, the prevalence of suicide ideation among adults during the COVID-19 was 18.1%. Logistic regression analyses indicated elevated odds of suicidal ideation among individuals in their 20s and 30s, those living alone, exhibiting fewer COVID-19 preventive behaviors, consuming COVID-19 information more frequently through media, and reporting higher levels of loneliness. Furthermore, within the group experiencing depression, anxiety, and increased drinking, greater levels of these factors correlated with higher odds of suicidal ideation. Based on the results, implications and significance of the study were discussed.

This study was conducted to understand the emotional and situational context where non-suicidal self-injury occurs in everyday life. Sixty adults(age 19-35) completed daily surveys assessing positive and negative emotions, stressful events, self-injury thoughts, and behaviors for two weeks. Using a total of 663 collected entries, we analyzed specific personal emotions and stressful events related to non-suicidal self-injurious thoughts and behaviors. As a result, high negative emotions, low positive emotions, and total stress event scores were significantly related to self-injury thoughts and behaviors. In the model in which both emotion and stress were inserted as predictors, the low level of positive emotion showed a significant related to non-suicidal self-injurious behavior. These results suggest that negative emotion management and overall positive emotion reinforcement are important in emotion regulation intervention for non-suicidal self-injurious patients. The meaning of this study is that it searched for risk factors of non-suicidal injury in everyday life using a short-term longitudinal method.

The purpose of this study was to measure repeated the process of non-suicidal self-injury individuals change in everyday life through the Ecological Momentary Assessment(EMA) daily diary. The study subjects of were 17 adults aged 19 to 29, accessed a link sent by text message on a cell phone and recorded a diary of the day's affects, interpersonal conflicts, self-injury thoughts, and behaviors once a day for two weeks. Using a total of 238 reported entries, the contextual factors of NSSI were examined, and the effects of affects and interpersonal conflicts on NSSI analyzed through a multi-level model. As a result, the negative affects of that day have a significant relation with within subject NSSI behavior and positive affects have a significant relation between subject NSSI behavior. These findings means that overall individuals with low positive affects have a higher risk of self-injury behavior compared to those with higher levles of positive emotions, and an increase in negative emotions on that day within an individual increases the risk of self-injury behavior on that day. In other words, it implies that it is important to manage negative emotions and strengthen overall positive affects for that day in the intervention of emotion-regulation of experienced self-injury individuals. It is meaningful that this study explored NSSI risk factors experienced in daily life through the short-term longitudinal study.

The purpose of this study was to investigate the mediating pathways of emotional regulators in relation to self-conscious negative emotions, including non-suicidal self-harm, guilt, shame, shyness, and internal hostility, further examining the gender difference in the mechanisms. The study subjects of were 652 college students from three universities in J district. Self-report questionnaires on self-harm, self-conscious negative emotions, and emotional control were administered to them. An analysis performed using model 4 of the process macro indicated that self-conscious negative emotions had a significant correlation with self-harming behavior and that this correlation was mediated by the emotional regulation of brooding. These results suggest that negative self-conscious emotions have a significant influence on self-harming behaviors, and brooding reinforces negative emotions then the risk of self-harming behaviors is amplified.

There are less studies on the elderly suicide even though it's steep increase. The purpose of the present study was to investigate factors that influence on the elderly suicide and to categorize them. For these purpose, A total of 23 cases were analyzed through qualitative contents analysis. Specifically, on the basis of the stress-vulnerability model, we scrutinized vulnerability factors(classified personal, family-environment factors) and precipitating events(classified interpersonal events) influencing on the elderly suicide. Personal factor was to be classified into personal mental health, physical health and problematic behavior. Family-environment factor was divided family relationship problem and economic problem. Interpersonal events belonging to the precipitating events was to be classified into interpersonal loss and interpersonal conflict. As the results of this study, elderly suicide classified into 3 types, that is, 'risk type suicide', 'event-response type suicide', 'complex type'. And then we discussed the characteristics of the suicidal types and suggestions for reduction of elderly suicide.

The purpose of this study was to compare the predictive accuracy of traditional prediction models (methods) and machine learning algorithms in predicting suicidal behaviors. The research aimed to go beyond a systematic review level and scientifically examine the predictive capabilities of these two techniques through meta-analysis, analyzing variables identified through domestic research, particularly at the regional level. In order to achieve this, a total of 124 studies, including 50 studies utilizing machine learning and 74 studies employing traditional methods, were included in the meta-analysis. The results of the study revealed that the integrated area under the curve (AUC) for studies using traditional methods was .770, which was lower than the integrated AUC value of .853 for studies using machine learning. Particularly, studies conducted in Asia (AUC = .944) demonstrated higher accuracy compared to studies in Western countries (AUC = .820) and Korea (AUC = .864). Additional analysis of the moderating effects in domestic research indicated that a higher proportion of males and the prediction of suicide attempts were associated with higher prediction accuracy. On the other hand, prediction accuracy was lower when the prediction target was suicide deaths and when studies utilized neural network analysis. This study synthesized various research findings on the prediction of suicidal behaviors, verified the effectiveness of prediction using machine learning, and holds significance in exploring variables applicable in the context of South Korea.

In this paper, we reviewed the community-based approaches to suicide prevention and national strategies for the decrement of suicide rate, and made some suggestions to decrease the suicide rate in South Korea. Until now, efforts to understand and prevent suicide have been pursued singularly by specialized interest groups such as psychiatrists, psychologists, mental health practitioners, and private organizations with little interaction between them, resulting in narrow approaches toward suicide that existed in relative isolation to one another and that have been largely ineffective. To decline the suicide rate in South Korea, the people lived in Korea community ought to have enough knowledge related to suicide and have to cooperate with other people. Through these efforts, Korea community would have established social safety networks to improve the community 's mental health. The most important factor in suicide prevention and declining the suicide rate is reducing the stigma and increase the self-help seeking behaviors associated with suicide and mental health. Therefore, suicide is not an individual problem solved by suicidal patient, but a community's problem solved by community in recognizing, managing and preventing suicide.

Recently, rates of depression and suicide of adolescents in industrialized countries, including Korea, were rapidly increasing. Adolescent depression was often associated with anxiety disorder, eating disorder, attention deficits hyperactivity/disruptive behavior disorder. and suicidal attempts. Epidemiological data about depression and suicide of adolescents are reviewed. Psychological theories of depression and suicide are integrated in terms of a control theory interpretation. Issues about 'relationships between depression and anxiety' 'relationships between depression and suicide' 'the reason why rates of depression and suicide are rapidly increasing at adolescence' 'the reason why the different prevalence of depression between female and male is conspicuous at adolescence' and 'Korean culture associated with depression and suicide of adolescents' are discussed in terms of the revised control theory interpretation.

This study analyzed the data from Korea National Health and Nutrition Examination Survey to examine factors associated with help-seeking among Korean adults with suicidal ideation. The results from binary logistic regression analysis showed that being currently married, low family income, and absence of diagnosed clinical depression were negatively associated with seeking help. Gender, age, education, the PHQ total score, and health insurance did not significantly change the probability of seeking help. The future suicide help-seeking intervention should focus on those who are less likely to seek help.

This study aimed to evaluate the relationship of ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life as well as burnout of kindergarten teachers for the first time in Korea. Also, it examined the odds ratio with ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life between burnout group and the comparison group through logistic regression analysis. A set of questionnaires was provided to a total of 310 participants (80 with higher burnout risk and 230 without burnout risk) from April 2015 to July 2015. All of participants were evaluated using the Korean Adult Attention Deficit Hyperactivity Disorder Scales, Beck's Depression Inventory, Beck's Anxiety Inventory, Baratte' Impulsivity Scale, Rosenberg's Self-esteem Inventory and Qulity of Life Scale. The results of this study indicated that burnout risk group is related to ADHD and anxiety and impulsivity. For the treatment of burnout in kindergarten teachers, effective evaluation and treatment of ADHD and impulsivity, as well as anxiety, seem to be necessary.
