Validation of "prodromal" criteria to detect individuals at ultra high risk of psychosis: 2 year follow up

TL;DR: Although young help-seekers meeting certain UHR criteria are at greater risk of psychotic disorder than those who do not meet them, caution is needed in their management, since a high transition rate can no longer be assumed.
