Systematic review identifies emotion regulation and family factors influencing non-suicidal self-injury in adolescents, suggesting new intervention approaches.
Adolescent mental health issues have garnered increasing social concern, among which non-suicidal self-injury (NSSI) has become a global public health problem due to its high prevalence and potential harm. Understanding the influencing factors and mechanisms of NSSI is essential for providing new perspectives on its early prevention and intervention. Through a systematic review and evaluation of theoretical models related to NSSI, this paper highlights that impaired emotion regulation serves as a core mechanism underlying the development of NSSI behavior. Future research should be grounded in China’s cultural context, strengthen longitudinal designs and multidimensional data collection, pay particular attention to the role of protective factors, and develop localized theoretical models to provide a theoretical basis for the prevention and intervention of NSSI among adolescents.
