Non‐Suicidal Self‐Injury in Adolescents: A Systematic Review on Prevention and Intervention Programmes

The findings from this study offer guidance to enhance nursing competencies in the early identification, risk assessment, and therapeutic management of non-suicidal self-injury among adolescents. Specifically, the results support the integration of evidence-based interventions such as emotional regulation training, mindfulness techniques, and psychoeducation into nursing practice. Moreover, this knowledge can inform the development of school-based prevention programmes led by community nurses and targeted interventions by mental health nurses, aimed at reducing the incidence and recurrence of non-suicidal self-injury behaviours.
