Open access. Early Intervention in Psychosis (EIP) services have been implemented with the dual aims of preventing harmful outcomes associated with early-onset psychosis and improving prognosis. However, concerns have been raised regarding the ethical implications of involving young people in EIP services. One way to ensure high ethical standards and promote good practice in EIP delivery is through governance of clinical practice. This study aimed to investigate the normative dimensions of good practice in EIP through examination of clinical guideline documents published in England over the past 15 years.
