ABSTRACT

Purpose: This study aimed to identify factors influencing non-suicidal self-injury (NSSI) among out-of-school youth in Korea, using the integrated theoretical model of self-injury development and maintenance. Methods: This cross-sectional study involved secondary data analysis from the 2021 Korean Teenagers' Mental Health Status Survey. The sample included 752 out-of-school youths. Data were analyzed using descriptive statistics, the χ²-test, independent t-test, and hierarchical logistic regression. Results: This study found that 321 out-of-school youths (42.7%) experienced NSSI. Factors associated with NSSI included higher levels of childhood abuse, increased depressive symptoms, lower self-esteem, higher perceived stress, and being boys. Conclusion: Mental health services should be provided to out-of-school youth who have experienced childhood abuse, exhibit high levels of depressive symptoms and perceived stress, and have low levels of self-esteem. Additionally, there is need to carefully identify and address NSSI in this population. Moreover, it is necessary to provide evidence-based, comprehensive, and tailored interventions to protect out-of-school youth from NSSI, considering sex.
