The Project: <\/strong>This Medical Research Council-funded project aims to characterise the aetiology of psychotic experiences in adolescence. It is hoped that by understanding the causes of psychotic experiences in 15- to 18-year-olds this knowledge can inform the development of early interventions<\/p>\n
