Researchers in the U.K. (lead by Richard Bentall) found that specific childhood adversities were significantly associated with specific forms of psychosis in adulthood in a review of the 2007 adult psychiatric morbidity survey. Those exposed to childhood rape were 9 times more likely to experience hallucinations, 3 times more likely to receive a diagnosis of schizophrenia, and being brought up in institutional care was associated with an 11 times greater risk of paranoia. There was a dose-response relationship observed between the number of childhood traumas and the risk of the symptom. Results will appear in Schizophrenia Bulletin.
