Although self-harm is often conceptualised as a way of regulating difficult emotions [11], in this study only half of those who self-harmed without suicidal intent and just over one third of those who self-harmed and wanted to die felt better as a result, suggesting that for many the action has not brought relief, or has replaced one distressing feeling for another. Knowledge such as this may be a useful starting point for entering discussion with teenagers as to which strategies for regulating difficult emotions might be more effective. Once greater understanding is reached regarding the causes, functions, outcomes and long-term risks of self-harm for teenagers, community-based interventions can be developed to reduce its prevalence and support those who engage in such behaviours.
