title: Trauma and psychosis: an analysis of the National Comorbidity Survey.
abstract: OBJECTIVE
  The authors hypothesized that the likelihood of psychosis classification would increase with traumatic experiences.
  
  
  METHODS
  Data from the National Comorbidity Survey were used to estimate the relationship between interpersonal trauma and the likelihood of a classification of psychosis.
  
  
  RESULTS
  Childhood physical abuse predicted psychosis, and there was a significant cumulative relationship between trauma and psychosis, with number of trauma types experienced increasing the probability of psychosis.
  
  
  CONCLUSIONS
  Overall, physical abuse predicted psychosis. In addition, a significant gender-by-rape interaction was observed, with rape having higher predictive value for psychosis in male subjects.
