Lecture 24: Psychopaths Thursday, March 31, 2011 - Hare Psychopathy Checklist- Revised (PCL-R) - Hare started research in about 1967 - Initially started research for people with anxiety disorders - Between his masters and PhD, he needed a job o Wife had a baby, needed to provide o He was in BC, worked in BC penitentiary (most serious offenders) o He came in there with a social cognitive degree, had no idea o Book “Without a Conscience”, first guy he met was Ray (psychopath), made his life miserable o Got his PhD, decided he wanted to look at anxiety, but wanted control group—psychopaths (Ray had no anxiety) o Got more interested in psychopaths o Developed the PCL-R, publised in 1991, could be called the gold standard —used across the world - Semi-structured interview o But you can’t believe what psychopaths tell you—they’re charming, persuasive, much better at lying (impression management) - File information o Collateral information o Get as much information as possible first, then interview and know when he/she is emitting, denying, exaggerating, etc. - Rate 20 items on 3-point scale (0 doesn’t apply, 1 to some extent, 2 definitely) o Can range from 0 to 40 o **Score of 30 or greater is the cut-off  Paul Bernardo got 35  Clifford Olsen got 38 - Male offenders on average: 22. - Female offenders on average: 19 o Also in general community, females would score slightly lower o Maybe due to the items captured in these measures o It was developed in correctional sample of all-male members - General population average: 4 - **Recent research on corporate psychopaths o Hare and Paul Babiek o Hare wrote another book, “Snakes in Suits” o Paper, “Walking the walk: psychopaths that work”—went into companies, got CEOs, individuals being fast-tracked for positions in company, assessed with PCL-R, but got a 4% base rate in terms of being psychopathic (not 1% like community)—those who score higher are more problematic (taking credit)—the boss thought they were great, but the people below them thought they were problematic - Psychopathy: Motives for Murder o Two prisons, out west and out east o 1 individual evaluated for psychopathy o Another person go in, read the information about the homicide, separate from the person who did the coding, and coded the homicides as being instrumental or reactive o Blind ratings (separate people doing ratings)—useful o Instrumental doesn’t have to be for money, could be for power, control, sexual purposes o Most homicide offenders score low on psychopathy, most likely reactive murder (72% of murders committed by non-psychopaths)  Some were still instrumental (28%) o High on psychopathy (30 or greater), most of them instrumental murder (93%)  Only 7% committed reactive murder o Major implications for how we treat individuals  Typically the kind of intervention for homicide is one-size-fits-all  Assumption that they need anger management, control impulses  Certainly that’s true for low PCL-R  But for the psychopaths who planned the murder, they don’t have issues with impulses and emotion. - David Krueger clip o Age 17: had history of sexually assaulting kids around 14 years o Had 200 victims up to 17—escalated to sexual homicide—killed 3 children o Documentary—he talks about what motivated him o Cold, unemotional, callous o Serial killer with psychopathic traits o Found not guilty by reason of insanity, put into maximum-security forensic psychiatric institution at the age of 17 o Self-obsessed, gave no thought to his victim o In Brockville, was fond of another patient (Dennis Kur), who had rebuffed his advances—he was angry, and planned to kill him (this was a bit more on the reactive side) o Psychopathic traits  No remorse  Early onset of the behaviours  Manipulation (Bruce, the staff, to let him out on a day pass— typically supervised by a staff member)  Very instrumental o *The combination of psychopathic traits and sexual deviance: deadly combination—predicts sexual recidivism o He’s been through many treatment programs, but learned not to tell about the deviant fantasies he still has, learned to manipulative better o Many of these individuals don’t see anything wrong with themselves—not amenable to treatment. They’re extrinsically motivated to change (want to get out), but not intrinsically motivated o Was one of the treated patients in the Rice et al. study - Psychopathy and treatment o Treated and untreated patients, psychopathic and non-psychopathic o Therapeutic community program, ran at max-security psychiatric hospital that ran from ‘60s to ‘70s o Had 10 year follow-up o Minimum 2 years treatment o Foster responsibility and empathy (would inhibit from violence) o Limited professional contact (patients ran the program) o Entry to program nonvoluntary o Failure following treatment  Those with 25 or below were non-psychopaths, using PCL-R  Above 25 were psychopaths  Not even extreme groups  *Found a 50% decrease in recidivism among non-psychopaths • This is fabulous  BUT for the untreated psychopathic group, recidivism was 55%. • **MAIN ISSUE: treated psychopaths had recidivism rate of 77% (Krueger) • It increased!! • This has been used to say things like the treatment makes psychopaths worse • Adele would rather conclude that the wrong type of treatment makes psychopaths worse • They were not changing their negative attitudes, grandiosity, substance abuse, arrogance, sense of entitlement—they just taught extra skills that they used to manipulate others - Porter study o Knew Porter—was intrigued—did psychopaths get out on early release or not?
