ABSTRACT
Objective@#This study aimed to examine how marital status, occupational status, and individual personality influence suicidal ideation and suicide attempts among Korean middle-aged adults, and explore the effects of their interaction. @*Methods@#A total of 2,464 middle-aged adults were surveyed about suicidality in the past year (1-year suicidality). Participants’ current marital and occupational status, including other demographic and clinical variables were investigated. Personality traits were assessed using the Big Five Inventory. The dependent variable was the presence of 1-year suicidality. Independent variables were current marital and occupational status. Generalized linear model (GLM) analysis was performed to adjust for other covariates. @*Results@#The group with 1-year suicidality had significantly lower income. It had a lower proportion of full-time employment, and higher percentages of part-time employment and unemployment. The GLM analysis results showed that marital and occupational status had no significant association with 1-year suicidality. Neuroticism and openness were positively associated with 1-year suicidality, whereas conscientiousness and extraversion had a negative association. Interactions between marital status and neuroticism, conscientiousness, and occupational status were significant. @*Conclusion@#Individualized social and psychological interventions for suicide prevention are required according to individual personality traits.
ABSTRACT
Objective@#The Patient Health Questionnaire–9 (PHQ-9) and PHQ-2 have not been validated in the general Korean population. This study aimed to validate and identify the optimal cutoff scores of the PHQ-9 and PHQ-2 in screening for major depression in the general Korean population. @*Methods@#We used data from 6,022 participants of the Korean Epidemiological Catchment Area Study for Psychiatric Disorders in 2011. Major depression was diagnosed according to the Korean Composite International Diagnostic Interview. Validity, reliability, and receiver operating characteristic curve analyses were performed using the results of the PHQ-9 and Euro Quality of life-5 dimension (EQ-5d). @*Results@#Of the 6,022 participants, 150 were diagnosed with major depression (2.5%). Both PHQ-9 and PHQ-2 demonstrated relatively high reliability and their scores were highly correlated with the “anxiety/depression” score of the EQ-5d. The optimal cutoff score of the PHQ-9 was 5, with a sensitivity of 89.9%, specificity of 84.1%, positive predictive value (PPV) of 12.6%, negative predictive value (NPV) of 99.7%, positive likelihood ratio (LR+) of 5.6, and negative likelihood ratio (LR-) of 0.12. The optimal cutoff score of the PHQ-2 was 2, with a sensitivity of 85.3%, specificity of 83.2%, PPV of 11.6%, NPV of 99.5%, LR+ of 5.1, and LR- of 0.18. @*Conclusion@#The PHQ-9 and PHQ-2 are valid tools for screening major depression in the general Korean population, with suggested cutoff values of 5 and 2 points, respectively.
ABSTRACT
Background@#Although it is known that a substantial proportion of the population experience loneliness, the consequence of loneliness remains unclear by countries and ages.Accordingly, this study aimed to assess the association between loneliness and suicidality in the general population of Korea.Method: A total of 5,511 Koreans aged 18–79 completed a tablet-assisted personal interview using the Korean version of the Composite International Diagnostic Interview and responded to questions about loneliness and lifetime suicidal ideation, plans, and attempts. A logistic regression analysis was used to examine the association between loneliness and suicidality. @*Results@#Approximately one-third of the Korean general population reported loneliness.Being older, never married, widowed, separated, or divorced, unemployed, and having a parttime job were all significantly related to loneliness. After adjusting for sociodemographic factors, individuals with loneliness were significantly associated with increased suicidal ideation (adjusted odd ratio [aOR], 4.05; 95% confidence interval [CI], 3.36–4.88), suicidal plans (aOR, 4.91; 95% CI, 3.34–7.21), and suicidal attempts (aOR, 4.82; 95% CI, 3.03–7.66). Even after adjusting for sociodemographic factors and mental disorders, suicidality remained statistically significant. Moreover, frequent, moderate-to-severe, and long-term loneliness were all associated with increased ORs for suicidality, regardless of sociodemographic factors and mental disorders. @*Conclusion@#Loneliness was associated with suicidal ideation, plans, and attempts. This study lays the foundation for public health policymakers to establish early intervention and mental health care support for lonely people.
ABSTRACT
Background@#This longitudinal study examined risk factors for future suicidality among North Korean defectors (NKDs) living in South Korea. @*Methods@#The subjects were 300 NKDs registered with a regional adaptation center (the Hana Center) in South Korea. Face-to-face interviews were conducted using the North Korean version of the World Health Organization’s Composite International Diagnostic Interview to diagnose mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Subjects were also asked about sociodemographic and clinical factors at baseline. At follow-up after three years, the NKDs (n = 172 respondents) were asked to participate in an online survey, responding to self-questionnaires about suicidality. Logistic regression analyses were used to explore associations between baseline variables and future suicidality among NKDs. @*Results@#Thirty (17.4%) of the 172 survey respondents reported suicidality at follow-up. The presence of health problems over the past year, any prior suicidality at baseline, a higher score on a trauma-related scale, and a lower score on a resilience scale at baseline were associated with greater odds of suicidality at follow-up after adjusting for age, sex, and educational level. Of all mental disorder categories, major depressive disorder, dysthymia, agoraphobia, and social phobia were also associated with significantly increased odds of suicidality at follow-up after adjusting for age, sex, educational level, and prior suicidality at baseline. @*Conclusion@#Resilience, a previous history of suicidality, and the presence of lifetime depressive disorder and anxiety disorder should be given consideration in mental health support and suicide prevention in NKDs.
ABSTRACT
Objective@#Mental health is a global concern and needs to be studied more closely. We aimed to estimate the prevalence of mental disorders and their associated factors among the general population in Korea. @*Methods@#The National Mental Health Survey of Korea 2021 was conducted between June 19 and August 31, 2021 and included 13,530 households; 5,511 participants completed the interview (response rate: 40.7%). The lifetime and 12-month diagnosis rates of mental disorders were made using the Korean version of the Composite International Diagnostic Interview 2.1. Factors associated with alcohol use disorder (AUD), nicotine use disorder, depressive disorder, and anxiety disorder were analyzed, and mental health service utilization rates were estimated. @*Results@#The lifetime prevalence of mental disorders was 27.8%. The 12-month prevalence rates of alcohol use, nicotine use, depressive, and anxiety disorders were 2.6%, 2.7%, 1.7%, and 3.1%, respectively. The risk factors associated with 12-month diagnosis rates were as follows: AUD: sex and age; nicotine use disorder: sex; depressive disorder: marital status and job status; anxiety disorder: sex, marital status, and job status. The 12-month treatment and service utilization rates for 12-month AUD, nicotine use disorder, depressive disorder, and anxiety disorder were 2.6%, 1.1%, 28.2%, and 9.1%, respectively. @*Conclusion@#Approximately 25% of adults in the general population were diagnosed with mental disorders during their lifetime. The treatment rates were substantially low. Future studies on this topic and efforts to increase the mental health treatment rate at a national level are needed.
ABSTRACT
Objectives@#This study examined the stigma against social withdrawal syndrome (hikikomori) among mental health practitioners, and compared levels of stigma against social withdrawal syndrome versus mental illness. @*Methods@#The participants were 133 mental health practitioners (28 males, 105 females) with experience of social withdrawal syndrome that self-reported levels of stigma against social withdrawal syndrome and mental illness. @*Results@#Stigma against social withdrawal syndrome was generally significantly lower than stigma against mental illness. However, mental health practitioners tended to agree they would be reluctant to become personally involved with a person that had experienced social withdrawal syndrome (e.g., dating, hiring). Levels of stigma also differed across mental health occupations. @*Conclusion@#This study suggests although mental health practitioners may generally have less negative attitudes toward social withdrawal syndrome in the context of mental illness, that they may also have some reservations about personal interactions with individuals with social withdrawal syndrome.
ABSTRACT
Objectives@#To develop a Loneliness and Social Isolation scale (LSIS) that can measure both social isolation and loneliness in order to understand the degree of social isolation in Korea. Exploratory and confirmatory factor analysis was used to examine the factorial validity of the scale. @*Methods@#The subjects of the study were 300 adults aged 19 or older who visited Samsung Medical Center and voluntarily expressed their willingness to participate in this research. Exploratory factor analysis (n=150) and confirmatory factor analysis (n=150) were conducted to construct the factorial structure model and to determine the model fit. @*Results@#Exploratory factor analysis showed a three-factor structure with a total variance of 65.8%; factor 1 consisted of social support, factor 2 of social networks, and factor 3 of items representing loneliness. After conducting confirmatory factor analysis on the three-factor models, a three-factor model consisting of 8 items (LSIS-8) and a three-factor model consisting of 6 items (LSIS-6) showed significant goodness-of-fit. Internal consistency for all items was good (Cronbach’s α=0.774), and correlations with existing social isolation and loneliness measures were significant. @*Conclusion@#This study is meaningful as provides a tool that comprehensively measures social support, social networks, and loneliness. We believe that the application of such tools that are relatively easy to apply in communities will aid understanding of the current state of social isolation and loneliness in Korea.
ABSTRACT
Objective@#This study aimed to introduce a 4-week long fully immersive virtual reality-based cognitive training (VRCT) program that could be applied for both a cognitively normal elderly population and patients with mild cognitive impairment (MCI). In addition, we attempted to investigate the neuropsychological effects of the VRCT program in each group. @*Methods@#A total of 56 participants, 31 in the MCI group and 25 in the cognitively normal elderly group, underwent eight sessions of VRCT for 4 weeks. In order to evaluate the effects of the VRCT, the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Packet was administered before and after the program. The program’ s safety was assessed using a simulator sickness questionnaire (SSQ), and availability was assessed using the presence questionnaire. @*Results@#After the eighth session of the VRCT program, cognitive improvement was observed in the ability to learn new information, visuospatial constructional ability, and frontal lobe function in both groups. At the baseline evaluation, based on the SSQ, the MCI group complained of disorientation and nausea significantly more than the cognitively normal elderly group did. However, both groups showed a reduction in discomfort as the VRCT program progressed. @*Conclusion@#We conclude that our VRCT program helps improve cognition in both the MCI group and cognitively normal elderly group. Therefore, the VRCT is expected to help improve cognitive function in elderly populations with and without MCI.
ABSTRACT
Objective@#This study aims to investigate the prevalence and psychological impact of social isolation and loneliness in South Korea. Loneliness and social isolation have been regarded as a risk to both physical and mental health. However, most studies have focused on the elderly; hence, there are limited studies on the characteristics of socially isolated or lonely people considering age. @*Methods@#A sample of 1,700 participants was selected from three major cities in South Korea. In-person interviews were conducted to evaluate loneliness, social isolation and mental health status. @*Results@#Among the participants, the prevalence of social isolation and loneliness was 17.8% and 4.1%, respectively. Males decreased the odds of loneliness (AOR 0.49, 95% CI=0.28–0.87), while increasing the odds of social isolation (AOR 1.44, 95% CI=1.12–1.86) after adjusting for age and sex. Greater depressive and social phobic symptoms were associated with increased odds of loneliness and social isolation. @*Conclusion@#Social isolation and loneliness are prevalent among Koreans and associated with depression, social phobic symptoms, and suicidality. This study provides a foundation for further research to investigate nationwide prevalence and a more in-depth analysis of loneliness and social isolation.
ABSTRACT
Background@#Although childhood maltreatment is a known risk factor for adulthood mental health, the impact of different types of childhood maltreatment on mental disorders is not yet clear. This study explored the association of each type of childhood maltreatment with adulthood mental disorders and suicidality in South Korea. @*Methods@#A total of 5,102 individuals from the general populations over the age of 18 responded to the Korean version of the Composite International Diagnostic Interview and questions about childhood maltreatment (emotional neglect, psychological abuse, physical abuse, and sexual abuse). To evaluate the odds ratio for mental disorders and suicidality associated with each type of childhood maltreatment, we used logistic regression analysis. @*Results@#About 17.0% of the respondents reported having experienced a type of maltreatment in childhood. According to the type, 9.4% reported physical abuse, 9.3% reported emotional neglect, 7.9% reported psychological abuse, and 3.8% reported sexual abuse. Exposure to each type of childhood maltreatment was associated with most types of mental disorders after adjusting for sociodemographic factors. Each type of childhood maltreatment victim was associated with suicidality (suicidal ideations, suicide plans, and suicide attempts).Dose-response patterns for suicide attempts were observed in all types of victims. Moreover, the respondents who experienced frequent childhood emotional neglect were 14 times more likely to have attempted suicide. @*Conclusion@#Childhood maltreatment was associated with mental health in adulthood.The findings show the need for early detection and intervention of victims of childhood maltreatment to minimize its negative impact on adult mental health.
ABSTRACT
Background@#This study investigated trends in the prevalence of major depressive disorder (MDD) by sociodemographic factors in South Korea. @*Methods@#National samples of the general population aged 18 years or older collected from the nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001 (n = 6,206), 2006 (n = 6,466), and 2011 (n = 5,986) were used. For MDD diagnosis, we conducted face-to-face interviews using the Korean version of the Composite International Diagnostic Interview. We performed logistic regression analyses stratified by gender, after adjusting for other sociodemographic variables, to calculate the 2006-to-2001 odds ratio (OR) and 2011-to-2001 OR by subgroups of sociodemographic factors to explore the association of MDD prevalence with sociodemographic factors over time. @*Results@#The prevalence of MDD in the general population of South Korea increased steadily from 2001, to 2006, and to 2011 (1.6%, 2.5%, and 3.1%, respectively). Among the men, the prevalence of MDD continued to increase significantly in 18–29 years of age group (2006: adjusted OR [AOR], 3.32; 2011: AOR, 7.42), at-risk drinking group (2006: AOR, 3.56; 2011: AOR, 4.77), and not living with a partner group (2006: AOR, 3.24; 2011: AOR, 3.25).Meanwhile, among the women, the prevalence of MDD continued to significantly increase in the below-average household income group (2006: AOR, 2.58; 2011: AOR, 2.59), at-risk drinking group (2006: AOR, 2.02; 2011: AOR, 2.47), and unemployed group (2006: AOR, 1.48; 2011: AOR, 2.04). @*Conclusion@#This study may provide significant information for public policymakers to allocate sufficient health resources on MDD to vulnerable groups, particularly, men aged 18–29 years and women living in households with below-average income, and for clinicians to develop appropriate screening and treatment modalities for MDD.

ABSTRACT
Objective@#The aim of this study was to estimate the prevalence of major psychiatric disorders among North Korean defectors (NKD) settled in South Korea. @*Methods@#The study population consisted of 294 North Korean defectors, aged 18 to 64 years settled in South Korea for 3 years or less. Between June 1, 2016 and October 31, 2016, face-to-face interviews were conducted using the North Korean version of the WHO-Composite International Diagnostic Interview (NK-CIDI) to diagnose DSM-IV psychiatric disorders. @*Results@#The lifetime prevalence of any DSM-IV psychiatric disorders was 62.2% in NKD and 25.0% in the general Korean population. The prevalence of specific disorders in NKD and general Korean population was as follows: 22.3% and 4.9% for major depressive disorder (MDD), 12.2% and 1.4% for post-traumatic stress disorder (PTSD), 18.0% and 4.8% for nicotine dependence, and 14.5% and 11.2% for alcohol abuse. The incidence of every single psychiatric disorder varied in each country. For instance, the generalized anxiety disorder, specific phobia, and alcohol use disorder occurred more frequently in North Korea whereas PTSD was more prevalent in other countries. @*Conclusion@#The prevalence of psychiatric disorders among NKD was quite higher than in the general population of South Korea.
ABSTRACT
Background@#This study investigated the impact of getting older than the mean marriage age on mental disorders and suicidality among never-married people. @*Methods@#We performed an epidemiological survey, a nationwide study of mental disorders, in 2016. In this study, a multi-stage cluster sampling was adopted. The Korean version of the Composite International Diagnostic Interview was conducted with 5,102 respondents aged 18 years or above. The associations between never-married status, mental disorders, and suicidality were explored according to whether the mean age of first marriage (men = 32.8 years; women = 30.1 years) had passed. @*Results@#Never-married status over the mean marriage age was associated with agoraphobia, obsessive–compulsive disorder, mood disorders, and major depressive disorder after adjusting for sociodemographic factors. Respondents with never-married status above the mean marriage age were associated with suicide attempts (adjusted odds ratio [aOR], 3.21;95% confidence interval [CI], 1.36–7.60) after controlling for sociodemographic factors and lifetime prevalence of mental disorders, while respondents with never-married status under the mean marriage age were not. Moreover, in respondents with never-married status, getting older than the mean marriage age was associated with suicidal ideations (aOR, 1.49;95% CI, 1.04–2.15) and suicide attempts (aOR, 3.38; 95% CI, 1.46–7.84) after controlling for sociodemographic factors and lifetime prevalence of mental disorders. @*Conclusion@#Never-married status above the mean first marriage age was associated with mental disorders and suicidality. These findings suggest the need for a national strategy to develop an environment where people with never-married status do not suffer even if their marriage is delayed.
ABSTRACT
Objectives@#Adult attention-deficit/hyperactivity disorder (ADHD) is an important mental health problem that needs resolution, especially considering the high rates of ADHD continuation from childhood to adolescence/adulthood and the high prevalence of ADHD in adults. Adults with ADHD have lifelong negative impacts and require close monitoring with long-term follow-up. Hence, the establishment of a Korean practice parameter for adult ADHD is necessary to minimize discontinuation of treatment and enable information sharing among Korean mental health professionals. @*Methods@#The Korean practice parameter was developed using an evidence-based approach consisting of expert consensus survey coupled with literature review. @*Results@#According to the expert consensus survey, the most commonly used diagnostic methods were clinical psychiatric interview (20.66%) and self-report scales (19.25%) followed by attention (14.71%) and psychological tests (14.24%). Key evaluation instruments currently available in Korea are the World Health Organization Adult ADHD Self-Report Rating Scale, Korean Adult ADHD Rating Scale, Diagnostic Interview for ADHD in Adults, Barkley Deficits in Executive Functioning Scale for adults, Comprehensive Attention Test, Conners’ Continuous Performance Test, and the subtests of Wechsler Adult Intelligence Scale, Digit Span and Letter-Number Sequencing. Although pharmacotherapy is recommended as the first-line of treatment for adult ADHD, we recommend that it be followed by a multimodal and multidisciplinary approach including psychoeducation, pharmacotherapy, cognitive behavior therapy and coaching. @*Conclusion@#The Korean practice parameter introduces not only general information for the diagnosis and treatment of adult ADHD on a global scale, but also the process of diagnosis and treatment options tailored to the Korean population.

ABSTRACT
OBJECTIVES@#The purpose of this study was to investigate the distinctive features of bodily panic symptoms and the predisposing conditions in Korean patients with panic disorder.@*METHODS@#This was a retrospective chart review study and the data were collected from twelve university-affiliated hospitals in Korea. The patients selected met the diagnostic criteria for panic disorder, were older than 20 years of age, and had initially visited a psychiatry department. The assessments included the chief complaints related to bodily panic symptoms, recent stressors, recent history of alcohol and sleep problems, and time to visit an outpatient clinic.@*RESULTS@#A total of 814 participants were included in the study. The most commonly experienced symptoms were cardiovascular and respiratory symptoms, which were observed in 63.9% and 55.4% of participants, respectively. Just before the onset of a panic attack, 25.6% of participants experienced sleep-related problems. Episodic binge drinking was also frequently observed (13.2%) and was more prevalent in men than in women (22.6% vs. 4.9%, p<0.001). About 75% of participants experienced stressful life events just before panic onset. Work-related issues were more prevalent in men than in women (22.0% vs. 13.4%, p=0.001). Family-related issues (4.8% vs. 14.1%, p<0.001) and conflict with a spouse or partner (4.0% vs.11.7%, p<0.001) were more prominent in women than in men.@*CONCLUSION@#Our results suggest that cardiovascular symptoms are the most common bodily panic symptoms in Korean patients. Our results suggest that a substantial portion of the Korean patients experienced stressful life events, sleep problems, and/or episodic binge drinking just before the onset of panic disorder.
