Objectives@#:This study investigated the level of sexuality knowledge and gender sensitivity and factors influencing on them among Korean high school and college students. @*Methods@#:129 questionnaires from high school and college students with consent forms, collected from July to December of 2022, were analyzed. After identification of participants’ gender, age, major, their report of the practicality of sex education, and their experience of violence or sexual assaults, participants’ level of sexualityknowledge and gender sensitivity were compared. @*Results@#:Females showed higher gender sensitivity, regardless of age and group (p=0.004). The early adulthood group (≥19 years old) showed higher sexuality knowledge and gender sensitivity, compared to those adolescents (<19 years old). Among college students, those who majored in health science were identified with higher sexuality knowledge and gender sensitivity, compared to non-health science major students(p<0.001; p=0.005). @*Conclusions@#:This study revealed the significant differences in sexuality knowledge and gender sensitivity according to sex, age, and majors in adolescents and early adults. Therefore, it seems to be necessary to consider the differences in sexuality knowledge and gender sensitivity among age, sex, and majors when establishing publicpolicy or legislation for sex crimes, including digital sex crimes.

Objective@#Schizophrenia-spectrum disorders and posttraumatic stress disorder (PTSD) share common clinical manifestations, genetic vulnerability, and environmental risk factors. We aimed to conduct a systematic review and meta-analysis of the comorbid prevalence of PTSD among schizophrenia-spectrum disorders. @*Methods@#We performed a meta-analysis to identify possible contributing factors to the heterogeneity among these studies. We systematically searched electronic databases with no restrictions on language of articles. @*Results@#We extracted 24 samples (18 for current prevalence and 6 for lifetime prevalence) from 22 studies and used a random effects model to estimate the pooled prevalence of PTSD among schizophrenia-spectrum disorders. The current and life prevalence of comorbid PTSD was 10.6% (95% confidence interval [CI]=6.3%–17.3%) and 13.0% (95% CI=5.3%–28.6%), respectively. Studies assessing psychotic experiences/involuntary admission reported the highest prevalence of comorbid PTSD (57.1%, 95% CI=43.6%–59.7%), whereas those assessing various anxiety disorders reported the lowest prevalence (1.1%, 95% CI=1.0%–5.5%). Heterogeneities of the subgroup analysis by similar objectives were largely homogeneous (I2=7.1–34.1). In the qualitative assessment, only two studies (9.1%) were evaluated as having a low risk of bias. @*Conclusion@#Our results showed that a careful approach with particular attention to assessing PTSD is essential to reliably estimate the prevalence of PTSD comorbid with schizophrenia-spectrum disorders. The reason for the wide discrepancy in the prevalence of comorbid PTSD among the four groups of studies should be addressed in future research.

Objective@#The response to antipsychotics in patients with schizophrenia is still unsatisfactory. Therefore, augmentation with other antipsychotics is common in clinical situations. The purpose of this study was to evaluate the improvement of psychiatric symptoms and side effects after amisulpride add-on therapy. @*Methods@#Forty patients with schizophrenia or schizoaffective disorder without treatment response to second-generation antipsychotics were included in this study. Psychotic symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS) and the Korean version of Calgary Depression Scale for Schizophrenia (CDSS) at baseline, 4 weeks, and 8 weeks after the addition of amisulpride. @*Results@#Among the 29 subjects who completed the 8-week study, 34.5% were responders according to PANSS total score. At week 8, the mean positive (p < 0.001), negative (p < 0.001), general (p < 0.001), and total (p < 0.001) PANSS scores and CDSS scores (p = 0.002) showed significant improvement compared to baseline. There was no increase in extrapyramidal side effects according to Simpson Angus Scale (p = 0.379) and Barnes Akathisia Rating Scale (p = 0.070) and no weight gain (p = 0.308) after the add-on treatment. @*Conclusion@#The addition of amisulpride for schizophrenia patients without therapeutic response to second-generation antipsychotics is considered an effective and safe treatment. This study's results suggested that augmentation of second-generation antipsychotics with amisulpride could be a useful option for patients with schizophrenia unresponsive to second-generation antipsychotics. Further studies investigating the efficacy of amisulpride add-on therapy using placebo control are necessary to confirm these results.

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.

Objective@#This study investigated the treatment response and cognitive enhancement effects of buspirone augmentation of escitalopram in patients with major depressive disorder (MDD), according to atypical feature subtypes of MDD. @*Methods@#An 8 week, randomized, parallel-controlled, open-label study was conducted. The Columbia Atypical Depression Diagnostic Scale was administered to evaluate atypical features. Patients were assigned randomly to the buspirone augmentation or non-buspirone groups. Symptom severity and cognitive function were evaluated using the 17-item Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Beck Depression Inventory, Beck Anxiety Inventory, digit span test, word fluency test, and Trail Making Tests A and B. @*Results@#A total of 89 patients were recruited. There were no significant differences in the measures between the groups; however, among the MDD patients without atypical features, the digit span and word fluency tests were improved by treatment. In the MDD patients without atypical features, the buspirone augmentation group showed a significant improvement on the digit span test compared to the non-buspirone group. @*Conclusion@#Buspirone augmentation did not demonstrate significant benefits in MDD patients; however, buspirone augmentation showed greater efficacy for the improvement of cognitive function in MDD patients without atypical features. Our study suggests that atypical features are an important factor for cognitive enhancement in buspirone augmentation treatment in patients with MDD.
Résumé
Objective@#Suicide is a huge nationwide problem that incurs a lot of socio-economic costs. Suicide also inflicts severe distress on the people left behind. The government of the Republic of Korea has been making many policy efforts to reduce suicide rate. The gatekeeper program, ‘Suicide CARE’, is one of the meaningful modalities for preventing suicide. @*Methods@#Multidisciplinary research team collaborated to update the ‘Suicide CARE’ to version 2.0. @*Results@#In the ‘Introductory part’, the authors have the time to think about the necessity and significance of the program before conducting full-scale gatekeeper training. In the ‘Careful observation’ part, trainees learn how to understand and recognize the various linguistic, behavioral, and situational signals that a person shows before committing suicide. In the ‘Active listening’ part, trainees learn how to ask suicide with a value-neutral attitude as well listening empathetically. In the ‘Risk evaluation and Expert referral’ part, trainees learn intervening strategies to identify a person’s suicidal intention, plan, and past suicide attempts, and connect the person to appropriate institutes or services. @*Conclusion@#Subsequent studies should be conducted to verify the efficacy of the gatekeeper program.
Résumé
Objective@#In 2011, “Suicide CARE” (Standardized Suicide Prevention Program for Gatekeeper Intervention in Korea) was originally developed for the early detection of warning signs of suicide completion, since there is a tendency to regard emotional suppression as a virtue of Korean traditional culture. A total of 1.2 million individuals completed the training program of “Suicide CARE” in Korea. @*Methods@#More sophisticated suicide prevention approaches according to age, sex, and occupation have been proposed, demanding for a more detailed revision of “Suicide CARE.” Thus, during the period from August 2019 to February 2020, “Suicide CARE” has been updated to version 2.0. The assessments on domestic gatekeeper training programs for suicide prevention, international gatekeeper training programs for suicide prevention, psychological autopsy interview reports between 2015 and 2018, and the evaluation of feedback from people who completed “Suicide CARE” version 1.6 training were performed. @*Results@#We describe the revision process of “Suicide CARE,” revealing that “Suicide CARE” version 2.0 has been developed using an evidence-based methodology. @*Conclusion@#It is expected that “Suicide CARE” version 2.0 be positioned as the basic framework for many developing gatekeeper training programs for suicide prevention in Korea in the near future.

OBJECTIVES: Chronic insomnia disorder is a common and one of the most distressing sleep disorders. This pilot study was conducted to compare the spatial function between insomnia disorder patients and good sleeping control. METHODS: We enrolled the 22 patients with chronic insomnia during over one year who met the DSM-5 diagnostic criteria of insomnia disorder and 27 normal sleeping controls. The Cambridge Neuropsychological Test Automated Battery (CANTAB) has been performed to compare the spatial cognitive function between insomnia disorder patients and good sleeping controls. RESULTS: The CANTAB results showed significant differences in the problems solved in minimum moves of Stockings of Cambridge test (t = −2.499, p = 0.017). The significant difference between two groups remained after controlling age, sex, and Beck Depression Index non-sleep scores (F = 5.631, p = 0.022). CONCLUSION: This study suggests that the patients with insomnia disorder have poor spatial planning function.

OBJECTIVE: This study investigated the proposed association between restless legs syndrome (RLS) and the prevalence of hypertension. METHODS: A meta-analysis was conducted based on searches of the PUBMED, EMBASE, Cochrane Library, and Korean electronic databases. Cohort and cross-sectional studies reporting the incidence of hypertension in individuals with RLS were included. Dichotomous data were pooled to obtain an odds ratio (OR) and 95% confidence interval (CI) for the prevalence of hypertension in individuals with RLS. The main outcome measure of the study was prevalence of hypertension in patients with RLS compared with a control group. RESULTS: One cohort study and eight cross-sectional studies were included in the meta-analysis. Individuals with RLS had an increased prevalence of hypertension (all studies: OR=1.13, 95% CI=1.04–1.23; cross-sectional studies: OR=1.12, 95% CI=1.01–1.24). However, in subgroup analyses controlling for cardiovascular risk factors, such as diabetes mellitus and dyslipidemia, the differences in the prevalence of hypertension between RLS and control patients were no longer significant. CONCLUSION: Patients with RLS may have a higher prevalence of hypertension, according to a pooled analysis, but the results remain to be confirmed in well-designed prospective studies.

OBJECTIVE: The purpose of this study was to determine the key components of Korean disaster psychiatric assistant teams (K-DPATs), to set up new mental health service providing system for the disaster victims. METHODS: We conducted an analytic hierarchy process (AHP) involving disaster mental health experts, using a pairwise comparison questionnaire to compare the relative importance of the key components of the Korean disaster mental health response system. In total, 41 experts completed the first online survey; of these, 36 completed the second survey. Ten experts participated in panel meetings and discussed the results of the survey and AHP process. RESULTS: It was agreed that K-DPATs should be independent of the existing mental health system (70.1%), funding for K-DPATs should be provided by the Ministry of Public Safety, and the system should be managed by the Ministry of Health (65.8%). Experts shared the view that K-DPAT leaders would be suitable key decision makers for all types of disaster, with the exception of those involving infectious diseases. CONCLUSION: K-DPAT, a new model for disaster mental health response systems could improve the insufficiency of the current system, address problems such as fragmentation, and fulfill disaster victims’ unmet need for early professional intervention.

OBJECTIVE: The provision of care for elderly people with dementia by healthy elderly caregivers is one of the new health-care paradigms in South Korea. The aim of this study was to determine whether this type of care, which includes cognitive stimulation, would improve the cognitive function of dementia patients and the quality of life of the healthy elderly caregiver. METHODS: Totals of 132 dementia patients and 197 healthy elderly caregivers participated in this study. We evaluated the cognitive function of the dementia patients at baseline and after providing the program for 6 months using the Korean version of the Consortium to Establish a Registry for Alzheimer's disease, 1st Edition (CERAD-K). We also evaluated the quality of life of the healthy elderly caregivers using the World Health Organization Quality of Life-Short Version (WHOQOL-BREF) at baseline and after 6 months. RESULTS: The word-list memory results of CERAD-K for the included dementia patients improved after 6 months (Z=-2.855, p=0.004). The WHOQOL-BREF score among the elderly caregiver also improved significantly (Z=-2.354, p=0.019). CONCLUSION: These data suggest that dementia care is associated with improvements in both the cognitive function of dementia patients and the quality of life of the healthy elderly caregivers.

Schizophrenia is a chronic and debilitating mental disorder. The persisting negative and cognitive symptoms that are unresponsive to pharmacotherapy reveal the impairment of neuroprotective aspects of schizophrenia. In this review, of the several neuroprotective factors, we mainly focused on neuroinflammation, neurogenesis, and oxidative stress. We conducted a narrative and selective review. Neuroinflammation is mainly mediated by pro-inflammatory cytokines and microglia. Unlike peripheral inflammatory responses, neuroinflammation has a role in various neuronal activities such as neurotransmission neurogenesis. The cross-talk between neuroinflammation and neurogenesis usually has beneficial effects in the CNS under physiological conditions. However, uncontrolled and chronic neuroinflammation exert detrimental effects such as neuronal loss, inhibited neurogenesis, and excessive oxidative stress. Neurogenesis is also a major component of neuroprotection. Adult neurogenesis mainly occurs in the hippocampal region, which has an important role in memory formation and processing. Impaired neurogenesis and an ineffective response to antipsychotics may be thought to indicate a deteriorating course of schizophrenia. Oxidative stress and excessive dopaminergic neurotransmission may create a vicious cycle and consequently disturb NMDA receptor-mediated glutamatergic neurotransmission. Based on the current evidences, several neuroprotective therapeutic approaches have been reported to be efficacious for improving psychopathology, but further longitudinal and large-sample based studies are needed.

OBJECTIVE: We aimed to identify depressive symptom profiles that indicated the presence of depressive disorder and present optimal cut-off sub-scores for depressive symptom profiles for detecting depressive disorder in elderly subjects with chronic physical diseases including diabetes, chronic obstructive pulmonary disease/asthma, and coronary artery disease, using the Patient Health Questionnaire-9 (PHQ-9). METHODS: Two hundred and thirty-one elderly patients with chronic physical diseases were recruited consecutively from a university-affiliated general hospital in South Korea. RESULTS: Greater severities of all 9 depressive symptoms in the PHQ-9 were presented in those with depressive disorder rather than those without depressive disorder. A binary logistic regression modeling presented that little interest [adjusted odds ratio (aOR)=4.648, p<0.001], reduced/increased sleep (aOR=3.269, p<0.001), psychomotor retardation/agitation (aOR=2.243, p=0.004), and concentration problem (aOR=16.116, p<0.001) were independently associated with increased likelihood of having depressive disorder. Receiver operating characteristics (ROC) curve analysis presented that the optimal cut-off value of score on the items for little interest, reduced/increased sleep, psychomotor retardation/agitation and concentration problem (PHQ-9) for detecting depressive disorder was 4 with 61.9% of sensitivity and 91.5% of specificity [area under curve (AUC)=0.937, p<0.001]. CONCLUSION: Our findings suggested that the diagnostic weighting of little interest, reduced/increased sleep, psychomotor retardation/agitation, and concentration problem is needed to detect depressive disorder among the elderly patients with chronic physical diseases.

PURPOSE: This study was conducted to compare the characteristics of first suicide attempt patients with self-poisoning with those of self-injured patients. METHODS: In this retrospective data analysis, data were collected from emergency department patients who made a first suicide attempt between October 2013 and January 2017. Data included demographic, socioeconomic, physical and mental health status, method of suicide attempt, and authenticity of suicide intent. Patients were classified into a self-poisoning and self-injury group. RESULTS: Among 2,252 patients, 788 patients were making their first suicide attempt. Of these patients, 443 were self-poisoning patients. Males were less common among the self-poisoning group. Cohabitants (303 [89.4%] vs. 193 [81.4%]; p=0.010), married state (214 [57.4%] vs. 108 [41.2%]; p<0.001), and asking for help after suicide attempt (136 [86.1%] vs. 103 [73.6%]; p=0.009) was more common in the self-poisoning group than the self-injury group. However, planned suicide attempt was more frequent in the self-injury group (26 [16.0%] vs. 9 [4.7%]; p=0.001). Moreover, authenticity of suicide intent was higher in the self-injury group (12 [11.3%] vs. 42 [40.4%]; p<0.001). CONCLUSION: In the self-poisoning group, there was a higher rate of females, married people, existing cohabitants, and tendency to ask for help after suicide attempt. There were also more impulsive suicide attempts in this group. The results presented herein will help prevent self-poisoning suicide attempts among high risk patients.

OBJECTIVE: There are conflicting reports about whether individual anxiety disorders are independently associated with suicidal ideation and suicide attempts. We examined whether anxiety disorders are related to suicidal ideation and suicide attempts in a community sample of South Korean adults. METHODS: In-person interviews based on the South Korean version of the Composite International Diagnostic Interview were conducted to diagnose mental disorders. Multivariate logistic regression analysis was performed to examine whether anxiety disorders were associated with suicidal ideation and suicide attempts. Each regression model treated lifetime diagnosis of anxiety disorders as independent variables. Sociodemographic characteristics, cohabitation status, lifetime history of mood disorders, alcohol use disorders, and psychotic disorders were included as covariates. RESULTS: Nationally representative sample of 6,510 South Korean adults aged 18–64 years was recruited. Multivariate analysis adjusted for psychiatric comorbidity and sociodemographic variables revealed that generalized anxiety disorder (GAD) [2.34, 95% confidence interval (CI) (1.27, 4.33)], post-traumatic stress disorder (PTSD) (3.50, 95% CI: 2.16, 5.68), specific phobia (1.55, 95% CI: 1.14, 2.11), social phobia (2.97, 95% CI: 1.27, 6.94), and obsessive-compulsive disorder (OCD) (5.58, 95% CI: 2.70, 11.6) were associated with suicidal ideation, whereas only social phobia (3.78, 95% CI: 1.41, 10.1) and PTSD (5.13, 95% CI: 2.81, 9.37) were associated with suicide attempts. CONCLUSION: Individual anxiety disorders are independently associated with suicidal ideation and/or suicide attempts. The importance of the early detection of anxiety disorders and of assessing the suicide risk in individuals with anxiety disorders is emphasized.

OBJECTIVES: Disasters exert substantial effects on the mental health of victims and bereaved populations. Thus, a systematic framework for preparing and providing psychosocial and mental health services is necessary. The current attitudes toward and knowledge of disaster mental health-related factors among the general population provides one component for development of the disaster mental health services framework. METHODS: The authors analyzed a web-based survey for disaster mental health-related factors among the general population. Responses for the knowledge and perception for the disaster mental health services were compared between people who experienced and did not experience disaster. RESULTS: One thousand and three people completed the questionnaire. One hundred and seventy (16.9%) people experienced more than one disaster. People who experienced a disaster were more disturbed by disaster broadcasting or reporting than people who had not. People who experienced a disaster gave disaster mental health services an average score 63.5. People who experienced a disaster perceived group psychotherapy and self-help meetings as less important than those who had not. The recognition of both community mental health center and disaster mental health center was higher in the experienced group than non-experienced. CONCLUSION: This study revealed that general satisfaction with the current disaster mental health service is low, particularly among people who have used disaster mental health services. A national mental health system for disaster victims should be established with consideration for efficiency, effectiveness and accessibility.

Our study aimed to examine the knowledge and attitude of nursing personnel toward depression in general hospitals of Korea. A total of 851 nursing personnel enrolled at four university-affiliated general hospitals completed self-report questionnaires. Chi-square tests were used to compare the knowledge and attitude of registered or assistant nurses toward depression. In addition, binary logistic regression analysis was used to adjust for the following confounders: age-group and workplace. Registered and assistant nurses differed in their knowledge and attitude toward depression. The proportion of rational and/or correct responses were higher in registered nurses than assistant nurses for the following: constellation of depressive symptoms defined by DSM-IV (adjusted odds ratio [aOR], 3.876; P<0.001); suicide risk in depression recovery (aOR, 3.223; P=0.001) and psychological stress as a cause of depression (aOR, 4.370; P<0.001); the relationship between chronic physical disease and depression (aOR, 8.984; P<0.001); and other items. Our results suggest that in terms of the biological model of depression, the understanding of registered nurses is greater than that of assistant nurses. Moreover, specific psychiatric education programs for nursing personnel need to be developed in Korea. Our findings can contribute to the development of a general hospital-based model for early detection of depression in patients with chronic medical diseases.

OBJECTIVE: The abacus, first used in Asian countries more than 800 years ago, enables efficient arithmetic calculation via visuo-spatial configuration. We investigated whether abacus-trained children performed better on cognitive tasks and demonstrated higher levels of arithmetic abilities compared to those without such training. METHODS: We recruited 75 elementary school children (43 abacus-trained and 32 not so trained). Attention, memory, and arithmetic abilities were measured, and we compared the abacus with the control group. RESULTS: Children who had learned to use an abacus committed fewer commission errors and showed better arithmetic ability than did controls. We found no significant differences between children with and without abacus training in other areas of attention. CONCLUSION: We speculate that abacus training improves response inhibition via neuroanatomical alterations of the areas that regulate such functions. Further studies are needed to confirm the association between abacus training and better response inhibition.

Psychological autopsy is a systematic methodology for comprehensive investigation of psychiatric and behavioral factors assumed to be causative or related to death of the deceased. In many countries, psychological autopsy is considered the most direct and valuable tool for determining the relationship between risk factors and suicide. The case of Finland revealed that successful psychological autopsy studies could greatly contribute to the national suicide prevention strategy, which consequently reduced the national suicide rate. Despite the strengths of psychological autopsy for identifying risk factors of suicide and consequently preventing suicide, it has not been successful in Korea. Implementation of psychological autopsy has been inconsistent and sporadic across the provinces. In addition, standardization of psychological autopsy protocol and qualification of interviewers are needed. With all of these methodological issues in mind, conduct of as many psychological autopsies as possible is important in order to build an evidence-based suicide prevention strategy. For successful implementation of psychological autopsy in Korea, it is necessary to improve attitudes toward suicide and psychiatric conditions. Legal, administrative, and institutional support are also important. Finally, multidisciplinary approach based on the financial and legal support should be employed.
