The 2nd Edition of the PCL-R supplants its predecessor as the mandatory tool for assessing psychopathy. With it, you will find forensic assessments of psychopathy to be systematic and based on ironclad data and research. The revisions draw upon the large number of of articles, reports, presentations and dissertations that have appeared since the original publication in 1991.
The tool assesses psychopathic personality disorders in forensic populations. It provides complete coverage of the domain of psychopathic traits and behaviours. As in the original version, the PCL-R: 2nd Edition provides a Total score that is the most important score for the overall assessment of psychopathy. The Total score may be interpreted dimensionally in terms of degree of match to the prototypical psychopath, or it may be used categorically to help identify/diagnose psychopaths.
The PCL-R 2nd Edition is highly reliable and has impressive concurrent, predictive and construct validity. Ratings are made using a semi-structured 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 the PCL-R 2nd Edition with male and female offenders, substance abusers, sex offenders, African-American offenders and forensic psychiatric clients. Expanded for use with offenders in several countries, the PCL-R has become the international standard for the assessment of psychopathy.
Items are rated using the PCL-R Rating Booklet and the Quikscore Form obtains scores and profile results. Ratings are based on responses to the semi-structured interview and a review of collateral information. 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.
