Related Factors of Suicidal Ideation among North Korean Refugee Youth in South Korea.

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.
