title: Prevalence of interpersonal trauma exposure and trauma-related disorders in severe mental illness.
abstract: BACKGROUND
  Interpersonal trauma exposure and trauma-related disorders in people with severe mental illness (SMI) are often not recognized in clinical practice.
  
  
  OBJECTIVE
  To substantiate the prevalence of interpersonal trauma exposure and trauma-related disorders in people with SMI.
  
  
  METHODS
  We conducted a systematic review of four databases (1980-2010) and then described and analysed 33 studies in terms of primary diagnosis and instruments used to measure trauma exposure and trauma-related disorders.
  
  
  RESULTS
  Population-weighted mean prevalence rates in SMI were physical abuse 47% (range 25-72%), sexual abuse 37% (range 24-49%), and posttraumatic stress disorder (PTSD) 30% (range 20-47%). Compared to men, women showed a higher prevalence of sexual abuse in schizophrenia spectrum disorder, bipolar disorder, and mixed diagnosis groups labelled as having SMI.
  
  
  CONCLUSIONS
  Prevalence rates of interpersonal trauma and trauma-related disorders were significantly higher in SMI than in the general population. Emotional abuse and neglect, physical neglect, complex PTSD, and dissociative disorders have been scarcely examined in SMI.
