Hare Psychopathy Checklist Revised (PCL-R): 2^nd Edition

A world-wide leader for assessing psychopathology.

Qualification Level: A

Administer To: Individuals 18 years and older

Completion Time: 90–120 minutes for the interview section; 60 minutes for the collateral review (20-item rating scale)

Formats: Structured interview, expert rating form

Scoring Options: Hand scoring

Based on more than 10 years of extensive research, the Hare PCL-R assessment has become one of the leading instruments internationally for the assessment of psychopathy. Now, this classic tool has been revised, providing even greater clinical utility through the addition of four new subscores.

The test enables the clinician to determine an individual's PCL-R ratings on the basis of a semistructured interview and a review of collateral information. The assessment yields a dimensional total score, which can be used to help assess the degree to which an individual matches the prototypical psychopath or to help identify and diagnose psychopaths. Like the original test, the PCL-R: 2nd Edition also includes two primary dimensional factor scores that provide complete coverage of the domain of psychopathic traits and behaviors.

Building on this foundation, the interpretive power of the PCL-R test has been enriched in the 2nd Edition through the addition of two empirically derived and validated facets for each of the two primary factors. The new facet scores help pinpoint specific aspects of psychopathy, further increasing the tests' usefulness as part of the clinician's evaluation.

How to Use This Test

The PCL-R: 2nd Edition assessment can be used in institutional, detention, and community correctional facilities, in forensic psychiatric hospitals, and for pre-trial evaluations to help:

• Make a diagnosis of psychopathy based on the individual's functioning over time
• Support offender management decisions
• Provide solid empirical support for expert testimony

Key Features

• The PCL-R: 2nd Edition provides highly reliable concurrent, predictive, and construct validity.
  
  
• The PCL-R Rating Booklet facilitates rating the 20-item scale and the Quikscore™ Form provides a convenient method for recording ratings, obtaining scores, and profiling results.
  
  
• The PCL-R manual provides item descriptions, scoring procedures, extensive reliability and validity information, and normative data, including:
  
  
• New large-sample descriptive and validation data for using the test with male and female offenders, substance abusers, sex offenders, African-Americans, and forensic psychiatric clients.
  
  
• Percentile and T-score tables for male and female offenders, for male forensic psychiatric patients who have been assessed with the standard PCL-R procedure, and for male offenders and forensic psychiatric patients whose assessments are based solely on file reviews.

Hare PCL: Youth Version (PCL:YV)

Helps assess psychopathology in adolescents.

Completion Time: 90–120 minutes for the interview section; 60 minutes for the collateral review (20-item rating scale)

Formats: Structured interview, expert rating form

Scoring Options: Hand scoring

The Hare Psychopathy Checklist: Youth Version (PCL:YV) test can be used to help clinicians understand the factors that contribute to the development of adult antisocial behavior and psychopathy.

Using a semistructured interview and collateral information, the PCL:YV test measures interpersonal, affective, behavioral, and emotional features related to a widely understood, traditional concept of psychopathy. The PCL:YV test yields dimensional scores for clinical use, but it can also be used to classify individuals into groups for research purposes.

Hare P-SCAN Research Version (P-SCAN)
Checklist Version

A useful checklist to help in mental health and criminal justice settings.

Qualification Level: B

Administer To: Individuals 13 years and older

Completion Time: 10–15 minutes (90-item checklist)

Formats: Structured Interview

Scoring Options: Hand scoring

The purpose of the Hare P-SCAN instrument is to help individuals in the mental health and corrections environments systematize what many already do: form impressions and draw conclusions on the basis of their knowledge and their experience about patients, offenders, and suspects.

How to Use This Test

The P-SCAN assessment does not provide a clinical diagnosis or narrative assessment. Instead, the administrator uses his or her knowledge of the individual, along with all other information available, to rate the person's tendency toward psychopathic behaviors.

The checklist items depict relatively specific behaviors and low-level inferences about individuals. Items represent the three key facets of psychopathy:

• Interpersonal - Relationships with others; e.g., glibness, grandiosity, lying, conning
• Affective - Feelings and emotions; e.g., shallow emotions, lack of empathy, guilt, and/or remorse
• Lifestyle - Impulsivity, irresponsible behavior, parasitic, nomadic life style, lack of goals
