The Hare Psychopathy Checklist Revised Pdf Download
and in the criminal justice system is the Psychopathy Checklist– Revised (PCL-R; Hare, , ). Its psychometric properties, structure, and correlates are well-known. In this article I present new findings in which the 4 first-order factors of the PCL-R (Interpersonal, Affective, Lifestyle, Antisocial) can be used toFile Size: KB The Hare Psychopathy Checklist-Revised (PCL-R) is a diagnostic tool used to rate a person's psychopathic or antisocial tendencies. It was developed in the ’s by Dr. Robert Hare, a Canadian professor and researcher renowned in criminal psychology, who has spent three decades studying the concept known as the psychopath and based partly on Hare’s work with prison inmates in Vancouver Keywords: psychopathy, PCL–R, expert testimony, legal decision making, death penalty The Psychopathy Checklist–Revised (PCL–R) (Hare, , ) is consid- ered to be the most valid and reliable instrument for measuring the construct of psychopathy in correctional and forensic psychiatric populations (Fulero, ; Hare, ; Rice, ; Salekin, Rogers, & Sewell, ).Estimated Reading Time: 9 mins

Devised By: The Psychopathy Checklist PCL; Hare, consists of 22 items. The Psychopathy Checklist Revised was developed by Hare, R. inand was formally published in The 20item revision of the Psychopathy Checklist PCL-R is a rating scale designed to measure traits of psychopathic personality disorder. The PCL was derived from a factor analysis of characteristics e.
Qualifications and training: The PCL-R manual Hare, outlines the recommended qualifications for clinical use of the instrument.
They include: possession of an advanced degree in the social, medical, or behavioral hare psychopathy checklist .pdf download, such as a Ph. Registration with a state or provincial body that regulates the assessment and diagnosis of mental disorder as well as experience in working with forensic populations is required.
Adequate training and supervised experience in the use of the PCL-R is also required. Type of Instrument and Scoring Method: The PCLR is a item clinical rating scale, each item reflects a different symptom or characteristic of psychopathy.
The items are summed to yield total scores, hare psychopathy checklist .pdf download, ranging from 0 to 40, that reflects the degree to which an individual resembles the prototypical psychopath. Scoring PCL-R items requires. clinical judgement and inference, as well as the ability to carry out the task in an objective, professional manner Hare, A cutoff score of 30 or greater in some studies 25 is used to diagnose psychopathy. The PCL-R items are scored on the basis of an individuals functioning over most of the life span.
This means that a clinician or researcher who wants to measure change in psychopathic symptomatology during incarceration cannot use the PCL-R. The standard error of measurement for the PCL-R is approximately three points Hare, The PCL-R: Standard Errors of Measurement Reliability Estimate Alpha GC Mean SEM1 2. Source: Hare, In research on psychopathy, it is often necessary to identify groups of inmates with high, hare psychopathy checklist .pdf download, medium, and low levels of psychopathy hare psychopathy checklist .pdf download specific cut off scores Wong, The items can also be summed to yield scores on two distinct, yet moderately correlated.
Factor 1 of the PCLR reflects the affective and interpersonal features of psychopathy. Factor 1 has been labeled the Selfish, Callous, and Remorseless Use of Others. The items in this factor are concerned with impressions and inferences about interpersonal processes and are typically scored using both file information and impressions formed during the interview.
In particular, this factor reflects the psychopaths verbal and interpersonal hare psychopathy checklist .pdf download. The items that define the factor predominately depend on identifying the occurrence of specific behaviors, most often using the inmates file.
Criminal versatility Note: A dash indicates the item does not load on either factor. The PCLR is completed on the basis of a semi-structured interview of 90 to mins duration. The PCL-R can be scored on the basis of file information alone, provided that the material contained in the files is extensive and detailed.
It is important to note, that the PCL-R cannot be scored on the basis of an interview alone Hare, The PCL-R is costly to administer in terms of time and effort, as access to detailed interview and case history information, including criminal record is required. Fulero described the PCL-R as the state of the art, both clinically and in research use.
Female Offenders The PCL-R has been used with only a few samples of female offenders. Early indications from several studies are encouraging. Hare psychopathy checklist .pdf download far, hare psychopathy checklist .pdf download, it appears that the distribution of scores and reliability are comparable with those obtained in male samples. However, it appears that several items may not be as useful with female offenders as they are with male offenders Hare, Neary administered the PCL-R to female inmates of the Federal Prison.
The mean score for the sample was The mean total scores pooled across two raters was Interestingly, the sex of the rater appears to make little difference in the PCL and PCL-R assessments of male inmates or forensic patients. The results of the study show the interrater reliability and internal consistency to be high. The ICC for single and average ratings was.
The alpha coefficient was. Reliability: Cronbachs Alpha. Hare, argued that within North America the PCL-R shows considerable homogeneity. Classical indices of reliability alpha coefficients, inter- and intra-rater reliability ranged from. Internal consistency was assessed by Cronbarchs coefficient alpha, which ranged from. These results indicate that the PCL-R is a homogeneous, unidimensional scale. The mean correlation among the items on the PCL for samples 1 to 3 were.
These values are all consistent with the use of the PCL as a homogeneous, hare psychopathy checklist .pdf download, unidimensional scale. Test-Retest Reliability and Inter-rater Reliability. The generalizability coefficients were. The generalizability coefficient for a test-retest study was.
Summary of Generalizability Coefficients and Classical Test Score Indices of Reliability Obtained in Five Studies. Alpha coefficient Study N 72 71 Rater 1. The results indicate that the instrument is a very reliable generalizable instrument when used with prison populations.
These patients were assessed at intake, and then reassessed by a second rater blind to the intake assessment after a period of one month. The test-retest reliability of the PCL-R total scores was. According to Hare properly conducted assessments should routinely produce inter-rater reliabilities intra-class correlations of at least. Item Reliability. Parasitic lifestyle Poor behavioral control Promiscuous sexual behavior Early behavior problems Lack of realistic long-term goals Impulsivity Irresponsibility Failure to accept responsibility for own actions Many short-term marital relationships Juvenile delinquency Revocation of conditional release Criminal versatility.
The value of the PCL-R in forensic and clinical settings is supported by evidence of its predictive validity. According to Serinhare psychopathy checklist .pdf download, the PCL-R is equal to actuarial risk scales in predicting general recidivism, but is superior in predicting violent recidivism.
Criminal Violence. Psychopathic criminals tend to commit more crimes and are more violent that non-psychopaths. The discriminate functions were highly significant. Correlates of the PCL: Percentage of Inmates convicted of Violent Crime PCL Scores Crime Category Murder Possession of a weapon Robbery Assault Kidnapping Rape Vandalism Fighting Any violent crime N Correlates of the PCL Factors and Performance Variables Variables Institutional behavior N 1 2 PCL Hare psychopathy checklist .pdf download Score.
Note: Za Testing the difference between the correlations of Factor 1 and Factor 2 with the variable. Violent Recidivism A study conducted by Hart, Kropp, Hare concluded that psychopaths were more likely to violate the conditions of their release than non-psychopaths and the PCL total scores were found to be useful in predicting release outcome. security psychiatric sample. The relative risk for violent recidivism was 1.
The results showed that the high psychopathy group differed significantly from each of the other groups, hare psychopathy checklist .pdf download.
On average, the high psychopathy group remained in the program for a shorter period of time, put in less effort, hare psychopathy checklist .pdf download, and showed less improvement, than did either of the others groups. Content Validity. The items of the PCL-R are generally consistent with traditional and current clinical views on the personality traits and behaviors that define the construct of psychopathy.
The pattern of total scores is consistent with clinical descriptions of the psychopath as superficial, callous, exploitative, egocentric, emotionally shallow, non-anxious, and with little evidence of psychotic symptoms. Global clinical ratings and Checkleys core criteria for psychopathy correlated highly with Factor 1 and Factor 2 Hare, Construct Validity.
The PCL-R has good construct validity. A study conducted by Hart and Hare, examined the association between psychopathy and other mental disorders Axis I hare psychopathy checklist .pdf download Axis II criteria of the DSM in 80 male forensic patients.
The internal consistency of these final ratings Cronbachs alpha was. Preliminary analyses suggested that the factor structure of the PCL-R was identical to that obtained in criminal, non-psychiatric populations. In summary, PCL-R total scores were positively correlated with ratings of antisocial, histrionic, and narcissistic personality disorder and negatively correlated with ratings of avoidant personality disorder.
In addition, the most widely used psychiatric category related to psychopathy is Antisocial Personality Disorder APD. Although, the PCL and APD are designed to measure a more or less common construct and are significantly correlated with one another, they are not equivalent or interchangeable. A diagnosis of APD depends on almost entirely on evidence of antisocial behaviors, and, as a result, base rates in forensic populations are typically above.
In contrast. the PCL measures both personality traits and antisocial behaviors; base rates for PCL defined psychopathy in forensic populations are low, typically around 1. Convergent Validity. Convergent validity for the PCL-R has been demonstrated by its strong relationship. Discriminate Validity. Research on the discriminate validity of psychopathy diagnoses has important theoretical and practical implications.
It may yield clues concerning the position of psychopathy in a hierarchical structure of mental disorders. It may also help to improve predictions about future behavior and response to treatment in cases where disorders are thought to co-exist. This study also found that the pattern of correlations between the PCL and schizophrenia, hare psychopathy checklist .pdf download, ratings of other personality disorders, BPRS, and GAS scores provided further evidence for the discriminate validity of the PCL.
PCL total scores were either uncorrelated or negatively correlated with these measures.
