Results: Respondents with any traumatic events had three times the odds of other respondents of subsequently developing psychotic experiences (OR = 3.1, 95% CI 2.7-3.7), with variability in strength of association across traumatic event types. These associations persisted after adjustment for mental disorders.ConclusionsExposure to traumatic events predicts subsequent onset of psychotic experiences even after adjusting for comorbid mental disorders.application/pdfeng© Royal College of Psychiatrists (This is an author-produced electronic version of an article accepted for publication in the British Journal of Psychiatry.
