Read the full product description

The 2nd Edition of PCL–R™ is a vital revision to this classic tool, and supplants its predecessor as the mandatory tool for assessing psychopathy. With this 2nd Edition, you will find forensic assessments of psychopathy to be systematic, valid, and based on ironclad data and research.

2nd Edition revisions are based on the large numbers of articles, reports, presentations, and dissertations that have appeared since the original publication in 1991.

Hare PCL–R™ is a 20-item symptom-construct rating scale designed to assess psychopathic (antisocial) personality disorders in forensic populations.

It provides complete coverage of the domain of psychopathic traits and behaviours. The PCL–R™ Rating Booklet facilitates rating the 20-item scale, and the Quikscore™ Form is used to record the ratings, obtain the scores, and profile the results.

The ratings are based on responses to the semi-structured interview and on a review of collateral information.

As in the original version, PCL–R™: 2nd Edition provides a Total score that is the most important score for the overall assessment of psychopathy.

The Total score can be interpreted dimensionally in terms of degree of match to the prototypical psychopath, or it can be used categorically to help identify/diagnose psychopaths.

The 2nd Edition retains the original two Factors that reflect the two major facets of psychopathy: the callous, selfish, remorseless use of others (Factor 1) and a chronically unstable and antisocial lifestyle (Factor 2).

Interpretive power

The interpretive power of the PCL–R™ has been enriched, however, through the evolution of four subfactors. Factor 1 and Factor 2 divide into two empirically derived and validated subfactors: Factor 1a, Interpersonal (4 items); Factor 1b, Affective (4 items); Factor 2a, Impulsive Lifestyle (5 items); and Factor 2b, Antisocial Behaviour (5 items).

The initial response to these four subscales has been overwhelmingly positive, and is a testament to the clinical utility of these new subscale scores.

Ratings and scoring

PCL–R™: 2nd Edition is highly reliable and has impressive concurrent, predictive, and construct validity.

Ratings are made using a semistructured interview and a review of collateral information. Scoring is based on the degree to which a person’s personality/behaviour matches the Rating Booklet items.

The manual provides item descriptions, scoring procedures, extensive reliability and validity information, and normative data.

New large-sample descriptive and validation data are provided for use of PCL–R™ with male and female offenders, substance-abusers, sex offenders, African-American offenders, and forensic psychiatric clients. Expanded for use with offenders in several countries, PCL–R™ has become the international standard for the assessment of psychopathy.

Percentile and T-score tables are provided for male and female offenders, for male forensic psychiatric patients who have been assessed with the standard PCL–R™ procedure (interview plus file information), and for male offenders and forensic psychiatric patients whose assessments are based solely on file reviews.

New research findings derived from confirmatory factor analysis and item response theory are presented along with the implications of these findings for research, clinical and forensic purposes.
