Prevalence of DSM-IV Major Psychiatric Disorders among North Korean Defectors in South Korea.

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.

Perceived Trajectories of Past, Present, and Future Life Satisfaction of North Korean Defectors.

This study compared perceived trajectories of life satisfaction (LS) between North Korean defectors' (NKDs') and the general South Korean population and examined psychosocial factors associated with future LS. Data were obtained from 300 NKDs residing in South Korea and 5089 South Koreans using self-questionnaires and face-to-face interviews. LS values from 5 years ago (3.46 vs. 6.18) and at present (5.30 vs. 5.91) were lower in NKDs than the control group, but the inverse was true for expected LS score in 5 years (7.82 vs. 6.87). NKDs' LS trajectory showed a more statistically positive trend than that of the control group. Among NKDs, subjective sense of loneliness and satisfaction with one's sense of autonomy were associated with expected future LS. NKDs experience higher life satisfaction and expect an optimistic future relative to the control group. Social policies and therapeutic approaches to loneliness and improving a sense of autonomy may be beneficial.

Prevalence and Correlates of Suicidal Thoughts and Behaviors among North Korean Defectors.

OBJECTIVE: Despite the increasing number of North Korean defectors, research on their mental health conditions and suicidal thoughts and behaviors has not been conducted systematically. We examined the prevalence and risk factors of suicidal thoughts and behaviors in North Korean defectors. METHODS: This study focused on 300 North Korean defectors recruited from regional resettlement centers in South Korea. In-person interviews based on the North Korean version of the Composite International Diagnostic Interview were conducted to diagnose mental disorders and assess suicidal thoughts and behaviors. Logistic regression analyses were performed to evaluate the association between suicidal thoughts and behaviors and socio-demographic variables, and DSM-IV mental disorders. RESULTS: Lifetime prevalence of suicidal ideation, plans, and attempts were 28.3, 13.3, and 17.3%, respectively. Female sex (OR: 2.0, 95% CI: 1.0-3.9), presence of health problems in the past year (2.6, 95% CI: 1.4-4.6), and absence of both South Korean acquaintances (1.9, 95% CI: 1.0-3.4) and North Korean family (1.7, 95% CI: 1.0-2.9) were associated with higher odds of suicidal thoughts and behaviors, after adjusting for participant age, sex, and education. Presence of a mental disorder was associated with a significantly increased odd of suicide ideation, plan, and attempt. Of all mental disorder categories, agoraphobia had the strongest association with suicidal ideation (6.5, 95% CI: 2.0-21.6), plans (7.7, 95% CI: 2.5-23.2) and attempts (12.0, 95% CI: 3.5-40.8). CONCLUSION: Suicidal thoughts and behaviors among North Korean defectors are higher than the general population in South Korea, especially show high rates in transit countries. Further study should focus on the changes in suicidal thoughts and behaviors according to the settlement process and early prevention.
