With evidence about the association of trauma, physical, and emotional abuse with the etiology of psychotic disorders, British researchers investigated the validity of retrospective reporting. How reliable was it, and were the incidents described the result of psychosis or disordered thoughts? To answer this, they tested of answers given to questionnaires with the consistency of case records for 84 people. They report a high degree of confidence in retrospective reporting in an article appearing on-line in the Advance Access Schizophrenia Bulletin. Somewhat to their surprise, they say that people are "more likely to under report instances of abuse rather than overexaggerate their occurrence."
