Fifteen years on - early intervention for a new generation

Early intervention for psychosis (EIP) is a model of service delivery that aims to support young people with first-episode psychosis by providing the best available treatments, supporting recovery and preventing relapse. In this editorial, we review the evidence for EIP, how the model has developed since its inclusion in the NHS policy implementation guideline for mental health in 2001, challenges and areas of ongoing debate, and future development.
