The Offender Personality Disorder Pathway

Multi-method Evaluation of the Management, Organisation and
Staffing (MEMOS) in high security treatment services for people with Dangerous and Severe Personality Disorder (DSPD) (October 2010)

Mental disorder and offending:

• Men with a diagnosis of schizophrenia are between 4 and 8 times
  more likely to commit a violent offence
• For women it is between 3 – 23x more likely
• The link between schizophrenia and sexual offending is unclear
• Some evidence that affective disorders are linked to violence
  particularly bipolar disorder; unclear for sexual offending
• People diagnosed with ‘personality disorder’ are more likely to
  reoffend after hospital discharge than people with mental illness
• People diagnosed with ‘personality disorder’ are more likely to
  commit violence, and the prevalence rate of ‘personality disorder’
  is higher in people who have committed sexual offences (causality
  not inferred)
• Anti-social, borderline and narcissistic and histrionic personality
  disorders are most prevalent….
