PDs & Crime Flashcards
PERSONALITY & CRIME
- evidence does link some PDs w/criminal beh
- psychopathy linked to Eysenck’s “psychoticism”
- anti-social PD (APD)
PSYCHOTICISM-PSYCHOPATHY CONTINUUM
EYSENCK & EYSENCK (1976)
- psychopathy = extreme psychoticism
- continuity hypothesis = psychopathological disorders represent extreme normal personality
- psychoticism = criminality/psychopathy/schizophrenia predisposition
- ^ P = impersonal/emotionally indifferent/lack empathy -> impulsiveness/recklessness/anti-sociality
EYSENCK’S PERSONALITY THEORY & CRIME
- acknowledged limitations:
1. inapplicable to all crime
2. classical/operant conditioning emphasis doesn’t include all learning
3. other personality traits may be important - BUT theory = important; emphasis on hereditary/bio/environmental interaction on kid development
PD & CRIME
LEWIS & APPLEBY (1988)
- mere mention of personality disorder diagnosis has powerful effect on clinicians’ views
- stigma/discrimination from PD diagnosis shows evidence based diagnosis importance
- evidence suggests relation between PD/criminal beh
ARE PEOPLE W/PERSONALITY DISORDER DANGEROUS?
- majority ARE NOT dangerous/violent
- occasions when violence does occur involve APD
- psychopathy = rated w/APD; people w/diagnosis = ^ likely violent
- childhood trauma may lead to difficulties w/emotional regulation/impulsivity/empathy -> violence/anti-social beh
APD X PD: DIAGNOSTIC CRITERIA
- DSM-5 retains original 10 personality disorders BUT incl. hybrid dimensional-categorial model in appendix
- psychopathy ISN’T listed BUT measure incl. in hybrid alongside APD criteria
- APD diagnostic incl. psychopathy
APD X PSYCHOPATHY
- definitions = related
- dyssocial personality disorder (DPD) = listed w/APD in DSM-5
- dangerous/severe personality disorder (DSPD) = another psychopathy term
- overlap between categories suggests APD/DPD/psychopathy might be used interchangeably -> justice perception implications
FILONE ET AL (2014)
- potential stigma associated w/diagnostic labels = of particular courtroom importance
- label juror perceptions could have substantial impact on defendant sentencing recommendations
- pps read vignettes w/antisocial/dyssocial/psychopathy labels x crime type (white collar/violent crime)
FILONE ET AL (2014): RESULTS
- labels DIDN’T consistently impact sentencing recommendations/defendant perceptions
- ^ influenced by crime type > diagnosis
- white collar = ^ negative > violent offenders
- diagnostic label most influential on recidivism ratings/pps perceptions of violent offenders across all conditions
- psychopathy labels perceived at ^ risk > APD/DPD
EDENS & COX (2012)
- examined psychopathy/sociopathy/APD label prevalence/impact in capital murder cases
- surveyed defence team members at law conference
- when asked to estimate effects of any label on trial outcome respondents most frequently said considerable/extensive
BAKER ET AL (2021)
- examined BPD diagnosis/stigma
- methodology = experimental mock-jury w/2 dif scenarios to assess BPD impact on jury decision-making
- when defendant = “complex mental health”/severe personality disorder/borderline pattern -> ^ dangerous/segregation/coercive treatment rating > controls
