The effect of early trauma on North Korean refugee youths' mental health: Moderating effect of emotional regulation strategies.

Research shows that North Korean refugee youths are exposed to early traumatic events and are, therefore, vulnerable to mental health problems. We investigated the relationship between early trauma and emotion regulation strategies with symptoms of depression and attention-deficit hyperactivity disorder (ADHD) among North Korean refugee youths. In 2017-2018, we surveyed youths attending alternative schools for North Korean refugees in Seoul. One hundred and fifty-seven students (54 boys, 103 girls; 18.66 ± 2.82 years) completed questionnaires assessing early trauma experiences, emotion regulation strategies, depressive symptoms, and ADHD symptoms. Descriptive, correlation, and moderation analyses were conducted. Early trauma experience directly and negatively affected both the depressive and ADHD symptoms of North Korean refugee youths. The use of expressive suppression strategy significantly aggravated these effects of early trauma on both depressive and ADHD symptoms, indicating that it might be a risk factor for mental health problems among them. Contrarily, cognitive reappraisal seemed to buffer the effect of the expressive suppression strategy on depressive symptoms. A tailored intervention promoting emotion regulation strategies to prevent depressive and ADHD symptoms among this group is necessary.
