Motivations for Self-Harm in Young People and Their Correlates: A Systematic Review
Abstract
Self-harm in young people is associated with increased risk of suicide and other negative long-term outcomes. Understanding the motivations driving self-harm behaviours among young people can help to inform the development of preventative and treatment interventions. Self-harm rates have been rising, but reviews of the recent quantitative literature have not been undertaken. PsycInfo, Embase and Medline were systematically searched in September 2024 for studies published in the past ten years. Quantitative studies that examined motivations for self-harm (including prevalence and/or correlates) among young people (aged 10 to 24 years) with a history of self-harm were included in the review. The review was conducted in accordance with PRISMA guidelines and registered with PROSPERO (CRD42023429568). One hundred and seventeen studies met inclusion criteria. Intrapersonal motivations for self-harm (particularly emotion regulation, anti-dissociation and self-punishment) were more common than interpersonal motivations (e.g. peer bonding, communication). Intrapersonal motivations correlated with female gender, higher self-harm severity, current, repetitive and persistent self-harm, suicidality, poorer mental health and poorer emotion regulation. There was evidence to suggest that interpersonal motives are associated with younger age and some mental health difficulties (e.g. anxiety). Young people predominantly self-harm for intrapersonal reasons. Given that self-harm for…
