Psychopathy - Wikipedia
The Hare Psychopathy Checklist-Revised was devised by Canadian psychologist Dr. Hare in the s. A disclaimer before you dive in: you cannot diagnose yourself or someone you know with psychopathy right. The Hare Psychopathy Checklist-Revised (PCL-R) is a diagnostic tool used to rate a person's psychopathic or antisocial tendencies The Original Hare Psychopathy Checklist is a psychological assessment tool designed to assess the presence of psychopathy in individuals. It consists of a item checklist of perceived personality traits and observable behaviors. It is intended to be completed on the basis of a semi-structured interview along with a review of ancillary Psychopathy is most commonly assessed with the Psychopathy Checklist, Revised (PCL-R), created by Robert D. Hare based on Cleckley's criteria from the s, criminological concepts such as those of William and Joan McCord, and his own research on criminals and incarcerated offenders in Canada

Psychopathysometimes considered synonymous with sociopathyis traditionally a personality disorder characterized by persistent antisocial behaviorimpaired empathy and remorseand bolddisinhibitedand egotistical traits.
Hervey M. The creation of ASPD and DPD was driven hare psychopathy checklist .pdf download the fact that many of the classic traits of psychopathy were impossible to measure objectively. Hare later repopularized the construct of psychopathy in criminology with his Psychopathy Checklist. Although no psychiatric or psychological organization has sanctioned a diagnosis titled "psychopathy", assessments of psychopathic characteristics are widely used in criminal justice settings in some nations and may have important consequences for individuals.
The study of psychopathy is an active field of research, hare psychopathy checklist .pdf download the term is also used by the general public, popular press, and in fictional portrayals. A psychopath is a person suffering from a chronic mental disorder with abnormal or violent social behavior.
There are multiple conceptualizations of psychopathy, hare psychopathy checklist .pdf download, [4] including Cleckleyan psychopathy Hervey Cleckley's conception entailing bold, disinhibited behavior, and "feckless disregard" and criminal psychopathy a meaner, more aggressive and disinhibited conception explicitly entailing persistent and sometimes serious criminal behavior.
The latter conceptualization is typically used as the modern clinical concept and assessed by the Psychopathy Checklist. Efforts have therefore been made to clarify the meaning of the term. The triarchic model [1] suggests that different conceptions of psychopathy emphasize three observable characteristics to various degrees.
Analyses have been made with respect to the applicability of measurement tools such as the Psychopathy Checklist PCL, PCL-R and Psychopathic Personality Inventory PPI to this model. An early and influential analysis from Harris and colleagues indicated that a discrete category, or taxonmay underlie PCL-R psychopathy, allowing it to be measured and analyzed. However, this was only found for the behavioral Factor 2 items they identified, child problem behaviors; adult criminal behavior did not support the existence of a taxon.
Marcus et al. repeated the study on a larger sample of prisoners, using the PCL-R and seeking to rule out other experimental or statistical issues that may have produced the previously different findings.
They suggest that while for legal or other practical purposes an arbitrary cut-off point on trait scores might be used, there is actually no clear scientific evidence for an objective point of hare psychopathy checklist .pdf download by which to label some people "psychopaths"; in other words, a "psychopath" may be more accurately described as someone who is "relatively psychopathic", hare psychopathy checklist .pdf download. The PCL-R was developed for research, not clinical forensic diagnosis, and even for research purposes to improve understanding of the underlying issues, it is necessary to examine dimensions of personality in general rather than only a constellation of traits.
Studies have linked psychopathy to alternative dimensions such as antagonism highconscientiousness low and anxiousness low. Psychopathy has also been linked to high psychoticism —a theorized dimension referring to tough, aggressive or hostile tendencies. Aspects of this that appear associated with psychopathy are lack of socialization and responsibility, impulsivitysensation-seeking in some casesand aggression.
Otto Kernbergfrom a particular psychoanalytic perspective, believed psychopathy should be considered as part of a spectrum of pathological narcissismhare psychopathy checklist .pdf download, that would range from narcissistic personality on the low end, malignant narcissism in the middle, and psychopathy at the high end, hare psychopathy checklist .pdf download.
Psychopathy, narcissism and Machiavellianismthree personality traits that are together referred to as the dark triadhare psychopathy checklist .pdf download, share certain characteristics, such as a callous-manipulative interpersonal style. The current conceptions of psychopathy have been criticized for being poorly conceptualized, highly subjective, and encompassing a wide variety of underlying disorders.
Dorothy Otnow Lewis has written:. Just rummage through his records to determine what items seemed to fit. To this writer's mind, psychopathy and its synonyms e.
Over the years the authors' team has seen scores of offenders who, prior to evaluation by the authors, were dismissed as psychopaths or the like. Half of the Hare Psychopathy Checklist consists of symptoms of mania, hypomaniaand frontal-lobe dysfunction, which frequently results in underlying disorders hare psychopathy checklist .pdf download dismissed.
Psychopathic individuals do not show regret and remorse. This was thought to be due to an inability to generate this emotion in response to negative outcomes. However, inpeople with antisocial personality disorder and dissocial personality disorder were found to experience regret, but did not use the regret to guide their choice in behavior.
There was no lack of regret but a problem to think through a range of potential actions and estimating the outcome values. In an experiment published in March at the University of Hare psychopathy checklist .pdf download California neuroscientist Antonio R.
Damasio and his colleagues showed that subjects with damage to the ventromedial prefrontal cortex lack the ability to empathically feel their way to moral answers, and that when confronted with moral dilemmas, these brain-damaged patients coldly came up with "end-justifies-the-means" answers, leading Damasio to conclude that the point was not that they reached immoral conclusions, but that when they were confronted by a difficult issue — in this case as whether hare psychopathy checklist .pdf download shoot down a passenger plane hijacked by terrorists before it hits a major city — these patients appear to reach decisions without the anguish that afflicts those with normally functioning brains.
According to Adrian Rainea clinical neuroscientist also at the University of Southern California, one of this study's implications is that society may have to rethink how it judges immoral people: "Psychopaths often feel no empathy or remorse. Without that awareness, people relying exclusively on reasoning seem to find it harder to sort their way through moral thickets.
Does that mean they should be held to different standards of accountability? Socially, psychopathy typically involves extensive callous and manipulative self-serving behaviors with no regard for others, and often is associated with repeated delinquency, crime and violence.
Mentally, impairments in processes related to affect and cognitionparticularly socially related mental processes, have been found in those with the disorder.
Developmentally, symptoms of psychopathy have been identified in young children with conduct disorderand suggests at least a partial constitutional factor that influences its development. In terms of simple correlations, hare psychopathy checklist .pdf download, the PCL-R manual states an average score of An analysis of prisoner samples from outside North America found a somewhat lower average value of Studies have found that psychopathy scores correlated with repeated imprisonment, detention in higher security, disciplinary infractions, and substance misuse.
Psychopathy, as measured with the PCL-R in institutional settings, shows in meta-analyses small to moderate effect sizes with institutional misbehavior, postrelease crime, or postrelease violent crime with similar effects for the three outcomes. Individual studies give similar results for adult offenders, forensic psychiatric samples, community samples, and youth.
The PCL-R is poorer at predicting sexual re-offending. This small to moderate effect appears to be due largely to the scale items that assess impulsive behaviors and past criminal history, which are well-established but very general risk factors. The aspects of core personality often held to be distinctively psychopathic generally show little or no predictive link to crime by themselves.
For example, Factor 1 of the PCL-R and Fearless dominance of the PPI-R have smaller or no relationship to crime, including violent crime. In contrast, Factor 2 and Impulsive antisociality of the PPI-R are associated more strongly with criminality. Factor 2 has a relationship of similar strength to that of the PCL-R as a whole.
The antisocial facet of the PCL-R is still predictive of future violence after controlling for past criminal behavior which, together with results regarding the PPI-R which by design does not include past criminal behavior, suggests that impulsive behaviors is an independent risk factor. Thus, the concept of psychopathy may perform poorly when attempted to be used as a general theory of crime. Studies have suggested a strong correlation between psychopathy scores and violenceand the PCL-R emphasizes features that are somewhat predictive of violent behavior.
Researchers, however, have noted that psychopathy is dissociable from and not synonymous with violence. It has been suggested that psychopathy is associated with "instrumental", also known as predatory, proactive, or "cold blooded" aggression, hare psychopathy checklist .pdf download, a form of aggression characterized by reduced emotion and conducted with a goal differing from but facilitated by the commission of harm. However, contrary to the equating of this to mean exclusively "in cold blood", more than a third of the homicides committed by psychopathic offenders involved some component of emotional reactivity as well.
One study has found more serious offending by non-psychopathic offenders on average than by offenders with psychopathy e. more homicides versus more armed robbery and property offenses and another that the Affective facet of the PCL-R predicted reduced offense seriousness. Furthermore, the commission of domestic violence is correlated with Factor 1 of the PCL-Rwhich describes the emotional deficits and the callous and exploitative interpersonal style found in psychopathy.
The prevalence of psychopathy among domestic abusers indicate that the core characteristics of psychopathy, such as callousness, remorselessness, and a lack of close interpersonal bonds, predispose those with psychopathy to committing domestic abuse, and suggest that the domestic abuses committed by these individuals are callously perpetrated i.
instrumentally aggressive rather than a case of emotional aggression and therefore may not be amenable to the types of psychosocial interventions commonly given to domestic abuse perpetrators. Some clinicians suggest that assessment of the construct of psychopathy does not necessarily add value to violence risk assessment. A large systematic review and meta-regression found that the PCL performed the poorest out of nine tools for predicting violence. In addition, studies conducted by the authors or translators of violence prediction measures, including the PCL, show on average more positive results than those conducted by more independent investigators.
There are several other risk assessment instruments which can predict further crime with an accuracy similar to the Hare psychopathy checklist .pdf download and some of these are considerably easier, quicker, and less expensive to administer.
This may even be done automatically by a computer simply based on data such as age, gender, number of previous convictions and age of first conviction. Some of these assessments may also identify treatment change and goals, identify quick changes that may help short-term management, identify more specific kinds of violence that may be at risk, and may have established specific probabilities of offending for specific scores.
Nonetheless, the PCL-R may continue to be popular for risk assessment because of its pioneering role and the large amount of research done using it. The Federal Bureau of Investigation reports that psychopathic behavior is consistent with traits common to some serial killersincluding sensation seeking, a lack of remorse or guiltimpulsivitythe need for controland predatory behavior.
Psychopathy has been associated with commission of sexual crimewith some researchers arguing that it is correlated with a preference for violent sexual behavior. A study of conditional releases for Canadian male federal offenders found that psychopathy was related to more violent and non-violent offences but not more sexual offences.
Hildebrand and colleagues have uncovered an interaction between psychopathy and deviant sexual interestswherein those high in psychopathy who also endorsed deviant sexual interests were more likely to recidivate sexually. In considering the issue of possible reunification of some sex offenders into homes with a non-offending parent and children, it has been advised that any sex offender with a significant criminal history should be assessed on the PCL-R, and if they score 18 or higher, then they should be excluded from any consideration of being placed in a home with children under any circumstances.
The possibility of psychopathy has been associated with organized crimeeconomic crime and war crimes. Terrorists are sometimes considered psychopathic, and comparisons may be hare psychopathy checklist .pdf download with traits such as antisocial violence, a selfish world view that precludes the welfare of others, a lack of remorse or guilt, and blame externalization. Coordinated terrorist activity requires organization, loyalty and ideological fanaticism often to the extreme of sacrificing oneself for an ideological cause.
Traits such as a self-centered disposition, unreliability, poor behavioral controls, and unusual behaviors may disadvantage or preclude psychopathic individuals in conducting organized terrorism. It may be that a significant portion of people with the disorder are socially successful and tend to express their antisocial behavior through more covert avenues such as social manipulation or white collar crime.
Such individuals are sometimes referred to as "successful psychopaths", and may not necessarily always have extensive histories of traditional antisocial behavior as characteristic of traditional psychopathy. The PCL:YV is an adaptation of the PCL-R for individuals aged 13—18 years. It is, hare psychopathy checklist .pdf download, like the PCL-R, done by a trained rater based on an interview hare psychopathy checklist .pdf download an examination of criminal and other records.
The "Antisocial Process Screening Device" APSD is also an adaptation of the PCL-R. It can be administered by parents or teachers for individuals aged 6—13 years. High psychopathy scores for both juveniles, as measured with these instruments, and adults, as measured with the PCL-R and other measurement tools, have similar associations with other variables, including similar ability in predicting violence and hare psychopathy checklist .pdf download. There is positive correlation between early negative life events of the ages 0—4 and the emotion-based aspects of psychopathy.
The correlations are considerably lower from early- or mid-adolescence to adulthood. In one study most of the similarities were on the Impulsive- and Antisocial-Behavior scales. Some recent studies have also found poorer ability at predicting long-term, adult offending.
Some researchers have speculated that there are two subtypes of conduct disorder which mark dual developmental pathways to adult psychopathy. Childhood onset is argued to be more due to a personality disorder caused by neurological deficits hare psychopathy checklist .pdf download with an adverse environment. For many, but not all, childhood onset is associated with what is in Terrie Moffitt's developmental theory of crime referred to as "life-course- persistent" antisocial behavior as well as poorer health and economic status.
Adolescent onset is argued to more typically be associated with short-term antisocial behavior. It has been suggested that the combination of early-onset conduct disorder and ADHD may be associated with life-course-persistent antisocial behaviors as well as psychopathy. There is evidence that this combination is more aggressive and antisocial than those with conduct disorder alone.
However, it is not a particularly distinct group since the vast majority of young children with conduct disorder also have ADHD, hare psychopathy checklist .pdf download.
Some evidence indicates that this group has deficits in behavioral inhibition, similar to that of adults with psychopathy. The DSM-5 includes a specifier for those with conduct disorder who also display a callous, unemotional interpersonal style across multiple settings and relationships, hare psychopathy checklist .pdf download.
