The Early Intervention Mission study aims to improve the outcomes for people experiencing psychosis. We will try to do this by focusing on three key areas:

Better understanding of psychosis and related conditions, including what might cause them, better treatments for people with psychosis, and creating a group of people from across the UK who can join future studies.

You are invited to take part because you had an episode of psychosis or have been identified as at risk of psychosis. If you agree to take part in the study, you'll be asked to give your consent. You may be invited to an in-person study visit. During this visit, we will ask you some questions about yourself. We will take a sample and we will ask you to complete some questionnaires.

Over the course of the study, you'll be asked to complete further questionnaires either online or using an app. We will need to access your health records for the duration of the study, to see how you do over time. You can choose whether we access any other information about you, such as details about your education. The information you share during the study visits and follow-up questionnaires, as well as your medical records, will be stored safely and securely.

Researchers will be able to use your data only in a way that keeps your identity private. You can choose whether we keep this data and your sample after the study, and if you are happy to be contacted about other studies in the future.

This study does not include any treatment changes.

Taking part is voluntary and you can stop at any time without giving a reason. If you decide not to take part, you will continue to receive your usual care. As a thank you, you'll be compensated for your time after your initial visit and at various points through the study.

By taking part, you will help us to improve the understanding and treatment of psychosis in the future. If you would like more information, please talk to a member of the study team.
