Non-Suicidal Self-Injurious Behaviour

Non-suicidal self-injury (NSSI) is relatively common among adolescents, with prevalence estimates ranging from 13-45% in community samples. NSSI is associated with various mental health disorders, including depression, anxiety, and borderline personality traits. Evidence-based treatments for NSSI in youth include dialectical behaviour therapy (DBT) and mentalisation-based treatment, focusing on emotion regulation and interpersonal effectiveness skills.
