<p>Self-harm amongst young people has risen significantly in recent years, yet existing models fail to fully explain its underlying mechanisms. This paper applies René Girard’s theory of mimetic rivalry and escalation to self-harm, proposing that competition for social status and identity within peer groups and families may contribute to its development. In this framework, self-harm operates as a form of self-punishment, mirroring Girard’s concept of scapegoating; a ritualised resolution to the tensions produced by mimetic escalation. The study explores how social media amplifies these dynamics by intensifying social comparison and reinforcing cycles of imitation and rivalry. Current treatments may be limited in their efficacy as they primarily focus on precipitating factors and crisis resolution without addressing the mimetic mechanisms driving self-harm. Integrating mimetic theory into clinical practice could offer a new framework for intervention, helping young people recognise and disengage from destructive social dynamics. Additionally, the paper highlights the potential for systemic and group-based interventions that target mimetic escalation within peer and family relationships. By understanding self-harm as a product of mimetic processes, this perspective offers novel insights for research, clinical practice, and public health strategies aimed at addressing the rise in self-harm amongst adolescents.</p>
