Objective The purpose of this study is to identify the demographic variables that are affecting performances on the Logical Memory (LM) subtest included in the Korean version of the Wechsler Memory Scale (WMS)-IV and to provide normative data on the LM subtest for the middle-age and elderly Korean people. Methods The participants were 435 non-demented adults aging from 50 to 90 and with the educational level ranging from 0 to 21 years. Results Age and education were found to be significantly associated with performance on the LM subtest, while gender effect was not statistically significant. Therefore, we stratified the norm blocks by age and education. Age was divided into three groups: 50–59, 60–74, and 75–90 years. Education was stratified into three groups: 0–8 years, 9–12 years, and 13 years or more. Conclusion The normative data provided in the current study are expected to be useful in clinical and research settings to detect or define subtle changes in episodic memory in Korean adults and elderly, and can also be used for cross-cultural comparison of verbal episodic memory performance among elderly populations using different languages.
Objective We aimed to investigate the influence of area-level factors on adolescent suicide and to determine which variables differ according to age and sex. Methods We selected variables that were available for collection through an online database from 2005 to 2015 in the Korean Statistical Information Service and the Korea Labor Institute. We used administrative districts of Korea in 2017 for geographical classification. We examined the relationships between regional suicide rates and area-level variables in male and female subjects aged 10–14 years and 15–19 years. In addition, we analyzed area-level variables in adolescents aged 15–19 years according to sex. Results Our findings indicated that several area-level variables affected adolescent suicide rates, varying according to age and sex. Economic problems were shown to be more associated with suicide in male adolescents than in female adolescents. On the other hand, social fragmentation and health services were shown to be more associated with suicide in females. Conclusion Suicide in adolescents was attributable to area-level factors such as economic status, social fragmentation, and community health services. By identifying area-level variables affecting adolescent suicide rates, we will be able to contribute to implement mental health policies related to adolescent suicide.
Objective The objective of this study was to examine the factor structures of the a priori alternative models of the 12-items General Health Questionnaire (GHQ-12), its psychometric characteristics and gender measurement invariance in a sample of non-clinical Nigerian adolescents (n=1326; Mage=15.16). Methods The sample consisted of 606 (45.7%) males, who completed the GHQ-12 in addition to the Hospital Anxiety and Depression Scale (HADS), the Rosenberg Self-Esteem Scale (RSES) and the Suicidal Behaviors Questionnaire-Revised (SBQ-R). We compared 21 models to identify which has the best fit indices applying confirmatory factor analysis. Gender measurement invariance was examined with nested multiple-group confirmatory factor analysis (MGCFA). Results The model that best captures psychological distress was a three-factor model that was initially described among the Australian general population (CFI=0.952, SRMR=0.0310, RMSEA=0.042) (90%CI=0.035–0.049). The internal consistencies (ω) of this model and its dimensions were modestly satisfactory. The criterion validity of this model was supported via significant correlations with the other study measures. MGCFA supported the configural, metric and scalar gender invariances of this model. Conclusion A three-factor GHQ-12 model (anhedonia/sleep disturbances; social performance and Loss of confidence) is useful as a psychological distress assessment tool among Nigerian adolescents.
Objective This study was conducted to validate a Perceived Competence Scale for Disaster Mental Health Workforce (PCS-DMHW) designed to measure the core competences of mental health workers in disaster response situations at individual and organizational levels. core competences essentially required in disaster response situations were defined on the basis of literature review, focus-group interview with disaster response professionals, and expert judgment. Methods The preliminary items of the PCS-DMHW thus generated were administered to 509 participants consisted of mental health professionals and semi-professionals. The data retrieved from questionnaires were equally divided by two halves. The final items were determined through the exploratory factor analysis of the half data (n=255), and the construct validity was tested by performing the confirmatory factor analysis and criterion-related validity test of the remaining half data (n=254). Results Three factors were derived from the individual competences scale; 1) perceived competence of knowledge and skill, 2) ethic, and 3) qualification. And three factors were derived from the organizational competence scale; 1) teamwork, 2) network, and 3) followship. Conclusion The PCS-DMHW demonstrated fairly high reliability and validity. Finally, the necessity of continuous validation study and the application modalities of this scale in education and training settings were discussed.

Objective The biological rhythm is closely related to mood symptoms. The purpose of this study was to assess the differences in biological rhythms among subjects with mood disorder [bipolar I disorder (BD I), bipolar II disorder (BD II), major depressive disorder (MDD)] and healthy control subjects. Methods A total of 462 early-onset mood disorder subjects were recruited from nine hospitals. The controls subjects were recruited from the general population of South Korea. Subject groups and control subject were evaluated for the Korean language version of Biological Rhythms Interview of Assessment in Neuropsychiatry (K-BRIAN) at the initial evaluation. Results The mean K-BRIAN scores were 35.59 [standard deviation (SD)=13.37] for BD I, 43.05 (SD=11.85) for BD II, 43.55 (SD=12.22) for MDD, and 29.1 (SD=8.15) for the control group. In the case of mood disorders, biological rhythm disturbances were greater than that in the control group (p<0.05). A significant difference existed between BD I and BD II (BD I<BD II, p<0.001) and between BD I and MDD (BD I<MDD, p< 0.001) but no difference was observed between BD II and MDD. Conclusion BD II and MDD are similar to each other but different from BD I in biological rhythm patterns in early-onset mood disorder cases. Biological rhythm disturbances are similar for early-onset major depression and BD II.
Objective The image of the wicked stepmother has created a prejudice against stepmothers, which makes it difficult for them to adjust to their stepfamilies. This study compared fairy tales from different cultures to reestablish the nature of stepmothers. Methods Grimms’ Fairy Tales (GFT) was used to represent Western culture, with stepmother characters appearing in 15 out of 210 tales. “The Collection of Korean Traditional Fairy Tales” (KFT) was used to represent Eastern culture, with stepmother characters featured in 14 out of 15,107 tales. We examined the relationships between stepmothers and stepchildren in GFT and KFT. Results Daughters were abused more often than sons in both genres. In GFT, jealousy spurred the abuse in 12 of 15 cases, while in KFT greed was predominant in 12 of 14 cases. Conclusion The fairy tale portrayals of wicked stepmothers may be associated with the stigma children place on their stepmothers, which needs to be overcome.

This study investigated the association between OCS and the long-term prognosis of ACS in tandem with depression comorbidity and treatment. Methods A cross-sectional baseline study and a nested 24-week double-blind escitalopram-placebo controlled trial were carried out between May 2007 and March 2013, and then a 5–12-year follow-up for major adverse cardiac events (MACE) was conducted. A total of 1,152 patients with ACS were stratified by baseline depression comorbidity and treatment allocation into four groups: no depression (706 patients), depression and taking escitalopram (149 patients), depression and taking a placebo (151 patients), and depression and receiving medical care as usual (CAU; 146 patients). OCS were evaluated using the Symptom Checklist-90-Revised Obsessive-Compulsive symptom domain. During the follow-up, Kaplan-Meier event rates for MACE outcomes were calculated, and hazard ratios were estimated using Cox regression models after adjusting for a range of covariates. Results A higher OCS score at baseline was associated with a worse ACS prognosis after adjusting for relevant covariates and across MACE outcomes. This association varied according to the depression comorbidity. The association was significant in patients without depression and depressive patients receiving placebos and CAU, but not in depressive patients on escitalopram. Conclusion Evaluating OCS and depression is recommended during the early phase of ACS. Treatment for OCS may improve the longterm cardiac outcomes of patients with ACS.

Objective This study evaluated the outcomes of ischemic stroke patients according to delirium motor subtype. Methods This study included patients who were admitted to the stroke unit between August 2017 and March 2019 and met the DSM-5 diagnostic criteria for delirium. Patients were assessed twice weekly throughout their delirium episodes using the Korean version of the Delirium Motor Subtype Scale (K-DMSS) and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-98). The clinical characteristics and short-term outcomes of the patients were also assessed. Results A total of 943 stroke patients were included; the rate of incident delirium was 10.18%. Of the 95 delirium patients, 34 were classified as the hyperactive subtype, 30 as the mixed subtype, 25 as the hypoactive and six as no subtype. Among the subtype groups, the hypoactive subtype had the highest initial scores on the National Institutes of Health Stroke Scale (NIHSS; 6.72±4.75, p=0.02) and the modified Rankin Scale (mRS; 3.96±1.24, p<0.01). Additionally, the mixed and hypoactive subtypes had longer durations (p<0.01) and more severe symptoms of delirium (p=0.03) than the other motor subtypes, and the hypoactive subtype group had a significantly longer hospital stay (36.88±27.71 days, p<0.01) than the other subtype groups. After adjusting for baseline covariates in a multiple linear regression analysis, these differences remained significant. Conclusion The present results suggest that the motor subtype of delirium is associated with different characteristics and outcomes in ischemic stroke patients.
Objective Symptomatic remission have substantial effects in long-term schizophrenia outcome, but exact determinants of the employment. In this study, the relationship between employment and symptomatic remission in chronic schizophrenia patients and other factors related to employment were investigated. Methods 100 patients interviewed were evaluated by the Positive and Negative Syndrome Scale (PANSS), Functional Recovery Scale in Schizophrenia (FROGS), Global Assessment of Functioning (GAF), Quality of Life Scale (QoL) and Subjective Recovery Assessment Scale (SubRAS). Sociodemographic variables, clinical features, antipsychotic dose and past working history obtained from patient interviews were investigated. Results The patients of 40% who participate in the study were symptomatic remission, but only 53.5% of these patients weren’t employed. Young age, especially, -regardless of the onset of illness- working a job in the past, low and moderate use CPED (equivalent doses according to chlorpromazine), shorter disease duration, symptomatic remission was found to be closely related to employment. While QoL, FROGS, GAF, and SubRAS total scores of employment group were higher than the unemployment group, PANSS total scores in the unemployment group were higher than that of the employment group. There was a high correlation between the scales and employment status. Conclusion Employment status was closely related with the remission status. This study supports that symptomatic remission alone is not decisive for employment. It was found that younger age, past working history (before or after the disease), low and intermediate CPED antipsychotic use and shorter duration of disease were closely related to employment with symptomatic remission.
The purpose of this study was to develop a brief rating scale of post-traumatic stress disorder (PTSD) symptoms among sexual violence victims. We analyzed the data from 195 victims and 220 non-victims to select meaningful items from the original PTSD rating scales. We also examined the validity of the brief scale by assessing internal consistency and ROC curves. The optimal cutoff scores for each brief scales were obtained. The results showed that a different approach may be required for early intervention in different age groups.
