Prevalence of and Gender Differences in Psychiatric Disorders among Juvenile Detainees in South Korea: A Comparative Study

Abstract

Background and Objectives: High rates of psychiatric disorders and comorbidities have been reported in juvenile detainees, which have been associated with repeat offenses. However, research into this topic has been limited to Asian countries. This study aimed to examine the prevalence of psychiatric disorders and sexual differences among juvenile detainees in a detention center in South Korea. Materials and Methods: The participants comprised 54 males and 46 females, with a minimum intelligence score of 80. Psychiatric diagnosis was determined using the Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). The Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2) was used to investigate gender differences. Results: Using the MINI-KID, the most frequent diseases were conduct disorder (CD), alcohol dependence, suicidal tendency, and attention-deficit/hyperactivity disorder (ADHD), with statistically significant differences between men and women. Only alcohol abuse was higher in males, while the rest were higher in females. The items with a statistically significant gender difference in MAYSI-2 were alcohol/drug use, feeling depressed/anxious, somatic complaints, suicidal ideation, and traumatic experiences. All items for which gender difference was statistically significant were higher in the proportion of women. Conclusions: Juvenile detainees exhibit high rates of psychiatric disorders and comorbidities. CDs, alcohol dependence, and ADHD are the most common psychiatric disorders among juvenile detainees in South Korea. Assessment of and intervention in psychiatric disorders may help prevent further offenses. These findings highlight the importance of diagnosing and intervening in psychiatric disorders within juvenile detention systems.
