25
What do the results mean?
  • More men are psychopathic?
  • Or are we just less able to recognise the
    disorder
  • in women?
  • Assessor gender bias?
  • Men are aggressive, women are emotionally
  • unstable
  • Real gender differences in psychopathy?

26
Conclusions
  • CAPP promising tool for assessing
  • psychopathy across gender
  • More marked gender differences in
  • manifestation of symptoms?
  • Gender awareness in assessment of
  • psychopathy is essential!

27
Practical implications for assessing psychopathy
in women
  • Do not expect to see the same presentation
  • of psychopathy in women as in men
  • Be aware of your own potential male
  • psychopathy prototype bias
  • For now, use assessment tools to aid
  • formulation not diagnose!

28
Questions and discussion
29
Questions
  • What mechanisms might operate to create gender
    differences in psychopathy? (or in PD generally)
  • Why would psychopathy be different from other PDs
    in terms of gender differences? (Hare says it is!)
