DSM‐5 and the ‘Psychosis Risk Syndrome’: no different than any other diagnostictest
The ?Psychosis Risk Syndrome? is essentially a diagnostic prediction, and hence subject to the normal standards for evaluating a diagnostic test. We describe four key standards for evaluating a diagnostic test and demonstrate that none are currently met by our state?of?the?art techniques for assessing the risk of psychosis. Under these circumstances, the adoption of the ?Psychosis Risk Syndrome? by DSM?5 would probably lead to unintended, but adverse, consequences.
