Participants completed a comprehensive follow-up assessment battery, which included the Childhood Trauma Questionnaire (CTQ), a self-report questionnaire that assesses experience of several types of childhood trauma, including sexual trauma. Data were available on 233 individuals; the main outcome measure was conversion to psychosis. Total CTQ trauma score was not associated with transition to psychosis, but sexual abuse was associated with transition to psychosis. Those with high sexual abuse scores were estimated to have a transition risk 2–4 times that of those with low scores.
Clinicians “should be routinely assessing previous sexual trauma in the `at-risk' population, because it may pose an increased risk for transition to a psychotic disorder,” the researchers said.
