The validity of ICD-11 PTSD and complex PTSD in North Korean defectors using the International Trauma Questionnaire.

Background: The International Trauma Questionnaire (ITQ) is a self-report assessment focused on the core features of Post-Traumatic Stress Disorder (PTSD) and complex Post-Traumatic Stress Disorder (CPTSD). It is consistent with the organizing principles of the 11th revision to the WHO's International Classification of Diseases (ICD-11). Since the 1990s, the number of North Korean defectors (NKD) entering South Korea to escape human rights violations has been increasing rapidly, with 33,815 NKD settled by 2021. The South Korean government faces an important challenge in supporting NKD to successfully adapt and settle in South Korean society. NKD experience various traumatic events during the process of defecting and repatriation. Therefore, it is essential to understand the psychological disorders of NKD, especially PTSD and CPTSD. Objective: This study aimed to test the validity of the ITQ assessment and explore the differences in symptoms and quality of life between PTSD and CPTSD. Method: The study sample comprised 503 trauma-exposed NKD. Confirmatory factor analysis (CFA) and latent class analysis (LCA) were used to evaluate the validity of ITQ. One-way analysis of variances and post-hoc analyses revealed the difference in the Depression and Somatic Symptoms Scale (DSSS) and WHOQOL-BREF results among PTSD and CPTSD symptom LCA classes. Results: The CFA and LCA results supported the ICD-11 conceptualization of PTSD and CPTSD in NKD. The CFA results confirmed that both the first- and second-order models were statistically fit, but for community-dwelling NKD the first-order model had better model fit than the second-order model. The LCA findings revealed a four-class model with 'PTSD', 'CPTSD', 'DSO', and 'low symptom' classes. Compared to the PTSD class, CPTSD class had higher levels of depression and somatic symptoms and a lower quality of life. Conclusion: This study provided evidence that ITQ is a valid tool to assess PTSD or CPTSD in community-dwelling NKD.

Antecedentes: El Cuestionario Internacional de Trauma (ITQ en su sigla en inglés) es una evaluación de autoreporte focalizado en las características principales del Trastorno de Estrés Postraumático (TEPT) y del Trastorno de Estrés Postraumático complejo (TEPT-C). Es consistente con los principios organizadores de la onceava revisión de la Clasificación International de las Enfermedades (CIE-11) de la OMS. Desde 1990, ha aumentado rápidamente el número de desertores de Corea del Norte (NKD en su sigla en inglés) que han entrado a Corea del Sur para escapar de las violaciones a los derechos humanos, con 33,815 NKD instalados hasta 2021. El gobierno de Corea del Sur enfrenta un desafío importante en apoyar a los NKD para adaptarse e instalarse en la sociedad de Corea del Sur. Los NKD experimentan varios eventos traumáticos durante el proceso de deserción y repatriación. Por lo tanto, es esencial entender los trastornos psicológicos de NKD, especialmente TEPT y TEPT-C.Objetivo: Este estudio busca evaluar la validez de la evaluación ITQ y explorar las diferencias en los síntomas y la calidad de vida entre TEPT y TEPT-C.Método: La muestra del estudio estuvo compuesta de 503 NKD expuesto a trauma. Se usaron el análisis factorial confirmatorio (CFA en su sigla en inglés) y análisis de clases latentes (LCA en su sigla en inglés) para evaluar la validez de ITQ. Los análisis de una vía de las varianzas y los análisis post-hoc revelaron la diferencia en los resultados de la Escala de los Síntomas somáticos y Depresión (DSSS en su sigla en inglés) y WHOQOL-BREF entre los síntomas TEPT y TEPT-C de las clases de los LCA.Resultados: Los resultados de CFA y LCA apoyan la conceptualización del TEPT y TEPT-C de la CIE-11 en NKD. Los resultados del CFA confirmaron que tanto los modelos de primer y de segundo orden fueron estadísticamente adecuados, pero para los NKD viviendo en residencias comunitarias, el modelo de primer orden tuvo un mejor ajuste que el modelo de segundo orden. Los hallazgos del LCA revelaron un modelo de cuatro clases con las clases 'TEPT', 'TEPT-C', 'DSO', y 'baja sintomatología'. En comparación con la clase TEPT, la clase TEPT-C tuvo niveles más altos de síntomas somáticos y depresión y una calidad de vida más baja.Conclusión: Este estudio proporciona evidencia que el ITQ es una herramienta válida para evaluar TEPT o TEPT-C en NKD viviendo en residencias comunitarias.

Is accreditation in medical education in Korea an opportunity or a burden?

The accreditation process is both an opportunity and a burden for medical schools in Korea. The line that separates the two is based on how medical schools recognize and utilize the accreditation process. In other words, accreditation is a burden for medical schools if they view the accreditation process as merely a formal procedure or a means to maintain accreditation status for medical education. However, if medical schools acknowledge the positive value of the accreditation process, accreditation can be both an opportunity and a tool for developing medical education. The accreditation process has educational value by catalyzing improvements in the quality, equity, and efficiency of medical education and by increasing the available options. For the accreditation process to contribute to medical education development, accrediting agencies and medical schools must first be recognized as partners of an educational alliance working together towards common goals. Secondly, clear guidelines on accreditation standards should be periodically reviewed and shared. Finally, a formative self-evaluation process must be introduced for institutions to utilize the accreditation process as an opportunity to develop medical education. This evaluation system could be developed through collaboration among medical schools, academic societies for medical education, and the accrediting authority.

Research output on mental health problems in North Korea between 2006 and 2017: A bibliographic analysis of North Korean medical journal articles.

Despite the continuing interests in political, economic, and public health issues of North Korea, little is known about mental health problems in North Korea. To gain a glimpse into this area of interest, we aimed to explore the characteristics of mental health research in North Korea and to identify the emphasis therein. In this context, four North Korean medical journals were selected from the Information Center on North Korea, with publication dates 2006-2017 (inclusive). For this bibliographic study's scope, we targeted studies on psychiatric problems in humans. We first selected articles based on their titles, and then finalized the study sample after reviewing the full text of primary sample articles. For main outcome measures, we used the absolute number and proportion of mental health research articles relative to total publications and the distribution of papers by research themes as defined by ICD-10 categories. Collectively, four journals published 162 mental health research articles from 2006 to 2017. The yearly volume and proportion varied between two and twenty-four and between 0.3 % and 2.7 %, respectively. The most frequently addressed ICD-10 category was F40-48, namely 'Neurotic, stress-related and somatoform disorders,' and the most frequently investigated condition was somatoform disorders. In conclusion, there has been a slow but steady increase in the research volume of psychiatry and mental health problems since 2011. The finding that the highest amount of research was conducted on somatoform disorders may suggest that mental disorder symptoms may be represented differently under the influence of socialism in North Korea.

National Health Priorities under the Kim Jong Un regime in Democratic People's Republic of Korea (DPRK), 2012-2018.

The National Health Priorities (NHP) 2016-2020 is the healthcare policy which was most recently announced to the international community by the Democratic People's Republic of Korea (DPRK). However, understanding DPRK's internal and practical perspectives and priorities in the healthcare sector is difficult. Hence, there is a need to analyse domestic documents. One such document is the Sa-seol-a kind of editorial in the first issue of the each quarterly medical journal published in DPRK. We analyse the content of 56 Sa-seol published in eight medical journals during the Kim Jong Un regime (2012-2018), and then classified them in terms of their relevance to each of 12 items presented in NHP 2016-2020. Sa-seol mentioned a total of 612 medical and health issues which could be classified into 12 items based on NHP 2016-2020. We divided the items into three categories of concern in the NHP by summarising the total number of mentions: the areas of the most, medium and least concern. The areas of most concern (development of medical science and technology) are not directly related to the present improvement of health and rather, seem to focus on more future development. The areas of medium concern focused on disease control, health systems and social determinants of health. The areas of the least concern were emergency or disaster response and reproductive health services. This study suggests a two-track approach for healthcare cooperation with DPRK:, a well-balanced approach between 'present' and 'future' needs.

Copycat Suicide Induced by Entertainment Celebrity Suicides in South Korea.

OBJECTIVE: Throughout the past several years, there have been a number of entertainment celebrity suicides in South Korea. The aim of this study was to investigate the clustering of suicides following celebrities' suicides in South Korea from 2005 to 2008, particularly according to certain characteristics. METHODS: Seven celebrity suicides were examined and defined using the Korean Integrated Newspaper Database System (KINDS) and from these, we considered four affected periods occurring 28 days after each celebrity's suicide. A Poisson time-series autoregression model was used to estimate the relative risk of the total suicide number for each affected period from 2005 to 2008. Logistic regression analysis was performed to investigate whether there were specific increases in the numbers of suicides in subgroups matching each celebrity. RESULTS: There were significant increases in the risk of suicide during the affected periods. Remarkable increases were found in the subgroups matching each celebrity, especially in the group in which all factors (sex, age, and method) were similar. CONCLUSION: This study provides confirmation that a significant copycat effect was induced by these celebrities' suicides, especially among people who identified more with the celebrities. This implies that countermeasures for upright media coverage of celebrity suicides should be discussed and practiced properly in South Korea.

[The relationship between academic self-efficacy and academic burnout in medical students].

PURPOSE: The purpose of this study was to examine the correlation between academic burnout and academic self-efficacy in medical students. METHODS: The study group comprised 446 students in years 1 to 4 of medical school. They were asked to rate their academic burnout and academic self-efficacy on a scale. The data were analyzed by multivariate analysis of variance and regression analysis. RESULTS: Academic self-efficacy was correlated negatively with academic burnout explaining 37% of academic burnout. CONCLUSION: Academic self-efficacy (especially self-confidence) had the greatest effect on academic burnout. The implications of these results are discussed in terms of an evaluation and support system for students.

A 7-year follow-up study on the mental health of North Korean defectors in South Korea.

This study was conducted to describe the relationship of past trauma and current stress on the mental health of North Korean (NK) defectors living in South Korea 7 years after a baseline assessment. Of the 200 who participated in the initial study, 106 participated in follow-up. Previous data regarding past traumatic events experienced in North Korea and during defection, past posttraumatic stress disorder (PTSD), and their current stress levels were correlated with the participants' current mental health status including depression, anxiety, and PTSD. The rate of PTSD in the sample and the scores on the PTSD symptom scale decreased significantly from the baseline. The participants' current mental health was negatively related to previous traumatic experiences in North Korea and past symptoms of PTSD, but unrelated to previous trauma experienced during defection. In addition, although current mental health was negatively related to only current culture-related stress, it was unrelated to the level of current ordinary life stress. The results of this study suggest that PTSD symptoms decreased during the 7 years between assessments, and that current culture-related stress is the most important variable related to the mental health of NK defectors living in South Korea.

The factors affecting the development of national identity as South korean in north korean refugees living in South Korea.

OBJECTIVE: This study aims to observe the factors that influence the development of national identity of North Korean refugees who have resettled in South Korea. METHODS: The study population was comprised of 500 North Korean refugees who immigrated to South Korea in 2007. The variables measured national identity as South Korean, a scale for discrimination perceived during daily life, a social for supporting social network, a for childhood trauma experience, traumatic experiences in North Korea, and traumatic experiences during the escape process. Factor analysis was conducted on the result from the scale for national identity as South Korean which produced 4 factors including national consciousness, positive emotions, positive values, and negative values. Multiple regression was done to identify how variables such as demographic data, discrimination, social network, and past trauma had influenced each of 4 factors. RESULTS: National identity was negatively related by traumatic experience during childhood, perceived discrimination, and positively influenced by social networks. Positive emotion was related negatively to education level in North Korea and perceived discrimination, but positively related to traumatic experiences in North Korea. Negative value was related positively age and perceived discrimination but negatively related to supporting social network. CONCLUSION: The results of this study suggests that promoting social networks, decreasing discrimination and healing past traumas were important factors for North Korean refugees in South Korea to facilitate a new national identity as a South Korean.

Analysis of the Characteristics of Discussion Materials that Promote Group Discussion in the Medical Humanities.

PURPOSE: This study aims to analyze the characteristics of discussion materials that promote student participation in discussions, satisfaction with student instruction, and tutor intervention in the medical humanities. METHODS: We surveyed 117 premedical students and 7 tutors who attended 4-week group discussions in the medical humanities in 2010. We described the discussion materials using the following 4 characteristics as independent variables: material type, level of understanding, interest, and quantity. Dependent variables were: student participation in the discussion, student instruction satisfaction, and tutor intervention. Correlation analysis, multiple regression analysis, and crosstab were performed using SPSS 15.0. RESULTS: The correlation between the characteristics of the discussion materials differed by grade. When the books were chosen as the discussion material in the instruction of first-year premedical students, the correlation between level of understanding, interest, and quantity was negative. Higher levels of understanding of the material and interest in the material led to an increase in discussion participation among both first- and second-year premedical students. Higher levels of understanding and interest of the discussion material also increased student satisfaction with the instruction, regardless of grade. Finally, levels of understanding of the material affected the degree of tutor intervention. Tutors intervened more often in discussions with first-year premedical students than with second-year premedical students. CONCLUSION: Differences in grades and the understanding of the discussion material should be considered when choosing discussion materials. Further study is required to continue the development of the discussion model and improve methods of facilitate discussion among students in the medical humanities.

"I'm Not Happy, But I Don't Care": Help-Seeking Behavior, Academic Difficulties, and Happiness.

PURPOSE: Medical education is perceived as being very stressful, which leads to declines in subjective well-being in medical students. Therefore, student counseling is becoming an exigent issue. The goal of this study was to investigate the academic difficulties and subjective well-being of medical students to identify their needs with regard to counseling. In addition, we analyzed help-seeking behaviors of students to develop an effective counseling program. METHODS: We performed a survey (n=205) to determine the extent to which medical students encounter academic difficulties in their lives in medical school and how they attempt to resolve their problems. In addition, we used the Oxford Happiness Scale to examine the relationships between academic performance, previous help-seeking behavior, and happiness in medical students. RESULTS: Of various types of problems, 62% of medical students perceived learning difficulties to be the most serious issue in medical school. Despite encountering difficulties, more than 67% of students failed to seek help from faculty or their fellow students. There was a significant relationship between happiness score and previous help-seeking behavior. A lack of perceived seriousness was identified as the most significant barrier to seeking help. CONCLUSION: Access to counseling programs must be improved for students with apparent academic difficulties who do not seek counseling. Through such programs, students can learn and practice methods of coping with their difficulties and develop medical and professional competence.

Mental health and quality of life of North Korean defectors living in Japan.

The aim of this study was to clarify the effect of migration of North Korean defectors to different host countries on the mental health and quality of life of the migrants by comparing three subject groups: North Korean defectors living in Japan, a group of Japanese workers living in Japan (for comparison), and North Korean defectors living in South Korea. The North Korean defectors living in Japan scored significantly higher on the Beck Depression Inventory, and also scored lower across all domains of the World Health Organization Quality of Life Assessment than the other two groups. However, no significant difference in the overall quality of life score was observed between the North Korean defectors living in Japan and the Japanese workers, while the North Korean defectors living in South Korea scored significantly higher as compared to both. These findings suggest that the insecurity of social factors because of poor fluency in the language of the host country, unemployment and unclear nationality, and the limited support system may contribute to the poor mental health and low quality of life of North Korean defectors living in Japan. Migration may promote a sense of achievement and improve the overall quality of life, but attention must be paid to the pervasive depression in these migrants.

Reliability and validity of the Korean version of Obsessive-Compulsive Inventory-Revised in a non-clinical sample.

PURPOSE: The reliability and validity of a Korean version of the Obsessive-Compulsive-Inventory-Revised (OCI-R) was examined in non-clinical student samples. MATERIALS AND METHODS: The Korean version of OCI-R was administered to a total of 228 Korean college students. The Maudsley Obsessive Compulsive Inventory (MOCI), Beck's Depression Inventory (BDI), and Beck's Anxiety Inventory (BAI) were administered to 228 students. RESULTS: The total and each of subscale of the Korean OCI-R demonstrated excellent internal consistency, good test-retest reliability, moderate convergent validity and good divergent validity. CONCLUSION: It was concluded that the Korean version of the OCI-R has strong psychometric properties as the original version.
