  1. Psychopathy Chapter 4

  2. debate about the nature of psychopathy revealed in the various labels for it Antisocial personality disorder, dyssocial personality, sociopathy Cleckley (1941) criteria: superficial charm, absence of “nervousness”, unreliability, untruthfulness and insincerity, lack of remorse or shame, inadequately motivated , poor judgment and failure to learn by experience, general poverty in major affective reactions, specific loss of insight, unresponsiveness in interpersonal relations, and failure to follow any life plan Nature of the Psychopath

  3. Common Definition: the Psychopathy Checklist-Revised • 20 item symptoms rating scale • requires clinical/expert judgment • data obtained from 2 primary sources • review of collateral information (required) • interview/observation (recommended)

  4. PCL-R: Factor 1 • Glibness/superficial charm • Grandiose sense of self-worth • Pathological lying • Conning/manipulative • Lack of remorse or guilt • Shallow affect • Callous/lack of empathy • Failure to accept responsibility for own actions

  5. PCL-R: Factor 2 • Need for stimulation/proneness to boredom • Parasitic lifestyle • Poor behavioral controls • Early behavioral problems • Lack of realistic, long-term goals • Impulsivity • Irresponsible • Juvenile delinquency • Revocation of conditional release

  6. Additional PCL-R Items • Promiscuous sexual behavior • Many short-term marital relationships • Criminal versatility

  7. Types of psychopathy • Primary psychopathy • Prototypicalpsychopathy • Antisocial acts, irresponsible, lacking empathy, superficially charming • Secondary psychopathy • Not inherent, cause lies in factors such as low intelligence, some sort of social disadvantage, and impulsivity driven by anxiety

  8. Antisocial Personality Disorder (APD) and Psychopathy • APD is listed formally in the DSM-IV TR but the PCL-R items are listed under the associated features • APD diagnostic criteria are more behavioral while psychopathy criteria are behavioral and interpersonal/affective • Prevalence rates for APD are higher in correctional samples and the community than psychopathy

  9. Relationship of Criminal Behavior and Violence • General Violence and Criminal Behavior • Single biggest risk factor for violence • Commit more violent crimes • Commit proportionally more instrumental violence as compared to reactive • More likely to inflict serious harm but less likely to murder • Different motivations for violence • More likely to victimize strangers • Burnout not associated with later violence

  10. Sexual Violence • May have increased risk for sexual violence • Sexual promiscuity • Lack of responsiveness in relationships • Predictive of sexual recidivism • Higher PCL-R scores commit more frequent and more severe levels of violent sexual offenses • 10-15% of child molesters and 40-50% of rapists are psychopaths

  11. Violence in Civil Psychiatric Patients • Risk of violence much lower than general offenders • Importance of psychopathy civil psychiatric patients is less obvious • Psychopathy is a strong predictor of violence even in less violent samples

  12. Violence in Domestic Violence Perpetrators • Psychopathy of offenders with a history of domestic violence might be useful in predicting future violence • Studies differ in terms of domestic abusers or one who has committed domestic violence offenses • Relationship between psychopathy and domestic violence is not yet clear

  13. What else do we know about psychopathy? • Interpersonal/Affective • Cognition/Learning • Biological Basis • Treatment

  14. Interpersonal/Affective • Deficits in non verbal emotional processing • Language appears to be superficial • Seem to lack affective cognitions • Exhibit less fear and anxiety • Pseudo/sham emotions • Pathological deceit • Con and manipulate people

  15. Cognition/Learning • Passive-avoidance learning • failure to learn to from behaviors that punish • general cognitive impulsiveness and hypersensitivity to rewards • Narrowed attentional focus • specific deficit in automatic processing that results in unresponsiveness to contextual cues

  16. Biological basis • May demonstrate reduced fear in anticipation of unpleasant or painful stimuli • Do not exhibit global neuropsychological deficits • Exhibit functional brain deficits • Cerebral cortexes are less active • Fail to use certain parts while processing emotional stimuli

  17. Treatment of Psychopaths • May be less likely to form emotional attachments needed for effective psychotherapy • Stay in program for shorter periods of time • Less motivated • Violence for treated psychopaths (77%) is higher than untreated psychopaths (55%) • Gives them insight into the emotions of others, making them more “effective” criminals • Recent studies are challenging the beliefs that treatment is ineffective for psychopaths

  18. Special Groups • Women & Psychopathy • Probably valid as a construct • Prevalence 11-23% • Mean PCL-R score for incarcerated women = 13-18 • Factor structure appears to be different for women than men, may exhibit symptoms differently • Relationship to recidivism not shown to be as strong as with men, but may be related to rapid recidivism

  19. Ethnic and Cross Cultural Differences • Comparisons between Caucasian and African-American offenders • Preliminary evidence is not suggestive of dramatic differences • There are significant different cross-culturally • Lower prevalence rates and mean PCL-R scores outside of North America

  20. Children and Adolescents Need to be careful when extended the construct to children and adolescents PCL:YV is the comparison measure Appears to be a viable construct with similar properties as it does in adults Debate about appropriateness of diagnosis

  21. Legal and Ethical Implications • Significant increase in the admission of the PCL-R into courts • Discrepancy between legal and clinical definitions of psychopathy • Capital sentencing • Represents the most prevalent use of psychopathy • Only a small correlation between PCL-R score and institutional violence and • Profound impact on jurors
