Psychopathy Checklist Wikipedia. This article is about the psychological assessment. For the statistical test, see p value. The Psychopathy Checklist or Hare Psychopathy Checklist Revised, now the Psychopathy Checklistrevised PCL R, is a psychological assessment tool most commonly used to assess the presence of psychopathy in individuals. It is a 2. The PCL was originally developed in the 1. Canadian psychologist Robert D. Hare for use in psychology experiments, based partly on Hares work with male offenders and forensic inmates in Vancouver, and partly on an influential clinical profile by American psychiatrist Hervey M. Cleckley first published in 1. An individuals score may have important consequences for his or her future, and because the potential for harm if the test is used or administered incorrectly is considerable, Hare argues that the test should be considered valid only if administered by a suitably qualified and experienced clinician under scientifically controlled and licensed, standardized conditions. Hare receives royalties on licensed use of the test. In psychometric terms, the current version of the checklist has two factors sets of related scores that correlate about 0. Factor One closer to Cleckleys original personality concept than Factor Two. Astronomy Logbook Software. Hares checklist does not incorporate the positive adjustment features that Cleckley did. PCL R model of psychopathyeditThe PCL R is used for indicating a dimensional score, or a categorical diagnosis, of psychopathy for clinical, legal or research purposes. It is rated by a mental health professional such as a psychologist or other professional trained in the field of mental health, psychology, or psychiatry, using 2. Each of the items in the PCL R is scored on a three point scale according to specific criteria through file information and a semi structured interview. The scores are used to predict risk for criminal re offense and probability of rehabilitation. The current edition of the PCL R officially lists three factors 1. The previous edition of the PCL R8 listed two factors. Factor 1 is labelled selfish, callous and remorseless use of others.

Factor 2 is labelled as chronically unstable, antisocial and socially deviant lifestyle. There is a high risk of recidivism and mostly small likelihood of rehabilitation for those who are labelled as having psychopathy on the basis of the PCL R ratings in the manual for the test, although treatment research is ongoing. PCL R Factors 1a and 1b are correlated with narcissistic personality disorder. They are associated with extraversion and positive affect. Factor 1, the so called core personality traits of psychopathy, may even be beneficial for the psychopath in terms of nondeviant social functioning. PCL R Factors 2a and 2b are particularly strongly correlated to antisocial personality disorder and borderline personality disorder and are associated with reactive anger, criminality, and impulsive violence. The target group for the PCL R in prisons in some countries is criminals convicted of delict andor felony. The quality of ratings may depend on how much background information is available and whether the person rated is honest and forthright. Each of the 2. 0 items in the PCL R is scored on a three point scale, with a rating of 0 if it does not apply at all, 1 if there is a partial match or mixed information, and 2 if there is a reasonably good match to the offender. This is said2 to be ideally done through a face to face interview together with supporting information on lifetime behavior e. It can take up to three hours to collect and review the information.

High PCL R scores are positively associated with measures of impulsivity and aggression, Machiavellianism, persistent criminal behavior, and negatively associated with measures of empathy and affiliation. Early factor analysis of the PCL R indicated it consisted of two factors. Factor 1 captures traits dealing with the interpersonal and affective deficits of psychopathy e. The two factors have been found by those following this theory to display different correlates. Factor 1 has been correlated with narcissistic personality disorder,1. In addition, the use of item response theory analysis of female offender PCL R scores indicates factor 1 items are more important in measuring and generalizing the construct of psychopathy in women than factor 2 items. In contrast, factor 2 was found to be related to antisocial personality disorder,1. The two factors are nonetheless highly correlated1. Research, however, has failed to replicate the two factor model in female samples. Researchers Cooke and Michie suggested, using statistical analysis involving confirmatory factor analysis,1. The remaining items would be divided into three factors arrogant and deceitful interpersonal style, deficient affective experience and impulsive and irresponsible behavioral style. Hare and colleagues have published detailed critiques of the three factor model and argue that there are statistical and conceptual problems.

Again, these models are presumed to be hierarchical with a single, unified psychopathy disorder underlying the distinct but correlated factors. The Cooke Michie hierarchical three factor model has severe statistical problemsi. Hare and colleagues have published detailed critiques of the Cooke Michie model. New evidence, across a range of samples and diverse measures, now supports a four factor model of the psychopathy construct,2. The PCL R is widely used to assess individuals in high security psychiatric units, prisons and other settings. This may be of help in deciding who should be detained or released, or who should undergo what kind of treatment. It is also used for its original purpose to carry out basic psychology studies of psychopathy. The PCL R also has some wide use as a risk assessment tool that attempts to predict who will offend or reoffend. It has been touted as unparalleled in its ability in this regard, and there have been some positive studies, especially early on. However, several recent studies and very large scale meta analysis have cast serious doubt on whether it performs as well as other instruments, or better than chance, and to the extent that it does, whether this is largely due its inclusion of past offending history, rather than the personality trait scores that make it unique. In addition although in controlled research environments the inter rater reliability of the PCL R may be satisfactory, in real world settings it has been found to have rather poor agreement between different raters, especially on the personality trait scores. Further, a review which pooled together various risk assessment instruments including the PCL, found that peer reviewed studies on which the developer or translator of the instrument was an author which in no case was disclosed in the journal article were twice as likely to report positive predictive findings.
