Objective The aims of this study were to explore the prevalence of and identify predictors of anxiety and depression related to coronavirus disease of 2019 (COVID-19) in South Korea.Methods The analysis is based on a quota survey design and a sampling frame that permitted recruitment of a national sample of 1,014 individuals between March 17–31, 2020. Several standardized measurements were used, including GAD-7, PHQ-9, COVID-19 related fear, restrictions in deaily life, as well as sociodemographic information and physical and psychosocial needs during the pandemic. Multiple logistic regression was conducted to analyze the influence of sociodemographic factors, fear, and physical/psychosocial needs on anxiety and depression.Results Significant numbers of the respondents were identifiable anxiety (19.0%) and depression group (17.5%), respectively. This indicates that the depression and anxiety prevalence rate after the COVID-19 is substantially high compared to the depression rate of 2.6% in 2020 and 2.8% in 2018 both reported in the Korea Community Health Survey and the anxiety rate of 5.7% reported in 2016 Survey of Mental Disorders in Korea. Multiple logistic regression results showed age, COVID-19 related fear, and the level of restrictions in daily as significant factors in understanding and predicting the anxiety group. Likfewise, the COVID-19 related fear, restrictions in daily life, and need for economic support were important predictors in predicting the depression group.Conclusion Findings on predictors for greater vulnerability to anxiety and depression has important implications for public mental health in the context of the COVID-19 pandemic.

We examined factors affecting the depressive symptoms and the relationship between depression and quality of life among 131 North Korean adolescent refugees aged 12–24 years. We compared sociodemographic, social, and individual characteristics and perceived the quality of life between participants with and without depression. Thirty-seven refugees (28.2%) had clinically significant depressive symptoms. The refugees with depression were younger (t = 2.67; p = 0.009), more likely to be male (χ² = 6.98; p = 0.009), and more likely to have a Chinese father (χ² = 9.05; p = 0.003) than those without depression. The refugees with depression had lower levels of psychological social support (t = 2.96; p = 0.004) and resilience (t = 4.24; p < 0.001) and higher levels of alcohol problems (t = −2.08; p = 0.043), aggression (t = −3.15; p = 0.003), and post-traumatic stress disorder (PTSD; t = −2.89; p = 0.004). They also reported lower levels of life satisfaction (t = 3.31; p = 0.001) and had a more negative view of their future (t = 2.68; p = 0.010). Interventions to increase resilience, to decrease the impact of traumatic events, and to provide psychological support may be helpful for North Korean adolescent refugees at risk of depression.

North Korean refugees experience adaptation difficulties, along with a wide range of psychological problems. Accordingly, this study examined the associations between early traumatic experiences, negative automatic thoughts, and depression among young North Korean refugees living in South Korea. Specifically, we examined how different factors of negative automatic thoughts would mediate the relationship between early trauma and depressive symptoms. A total of 109 North Korean refugees aged 13–29 years were recruited from two alternative schools. Our path analysis indicated that early trauma was positively linked with thoughts of personal failure, physical threat, and hostility, but not with thoughts of social threat. The link with depressive symptoms was only significant for thoughts of personal failure. After removing all non-significant pathways, the model revealed that early traumatic experiences were positively associated with depressive symptoms (ß = 0.61, 95% CI = 0.48–0.73) via thoughts of personal failure (ß = 0.17, 95% CI = 0.08–0.28), as well as directly (ß = 0.44, 95% CI = 0.27–0.59). Interventions that target negative cognitions of personal failure may be helpful for North Korean refugees at risk of depression.

This study investigated the factors associated with suicidal ideation among 174 North Korean refugees (aged 13–27 years) residing in South Korea. Specifically, we compared sociodemographic, familial, social, and psychological characteristics between participants with and without suicidal ideation. Twenty-nine refugees (16.7%) had exhibited suicidal ideation in the past 12 months. These refugees had significantly lower levels of familial cohesion (U = 1459.0; p < 0.001), self-esteem (U = 1032.0; p < 0.001), and resilience (U = 1190.0; p < 0.001), as well as higher levels of expressional suppression (U = 1202.5; p < 0.001) and post-traumatic stress disorder symptoms (U = 1303.0; p = 0.001), (with Cohen’s d > 0.5), compared to those without suicidal ideation. A multiple logistic regression analysis showed that the level of emotional suppression and familial cohesion were significantly associated with suicidal ideation, after controlling for the other variables. Familial and individual interventions, particularly those focused on encouraging emotional expression and familial cohesion, will be useful for North Korean refugee youth, who have a high risk of suicide.
