Abstract
Non-suicidal self-injury (NSSI) is a prevalent and concerning issue in adolescent mental health, often intertwined with depressive symptoms. Despite extensive research on NSSI, a comprehensive understanding of its multifaceted nature and the intricate interplay of risk and resilience factors remains crucial. This Letter to the Editor examines a novel study by Yang et al, which utilized latent profile analysis and network analysis to delineate distinct NSSI subtypes within a Chinese adolescent population and investigate the underlying dynamics of associated factors. The study identifies three distinct NSSI subtypes: NSSI with depression, NSSI without depression, and neither, underscoring bullying as a prominent risk factor. Concurrently, the findings emphasized the pivotal role of emotional regulation and family support as protective factors. The focus of this article is to contextualize these findings within the broader framework of adolescent mental health and to highlight their implications for developing targeted interventions. These insights not only advance our understanding of adolescent NSSI but also provide a foundation for the development of targeted interventions that address the identified risk and protective factors. By focusing on these critical areas, mental health professionals can implement more effective strategies to mitigate NSSI behaviors and cultivate resilience in this vulnerable population.
