Computer scoring is completed using the Smartlink (V5) software on your PC or through the PAA Scoring Bureau Service. The PCL-R:2 may be hand or computer scored. 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. 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. Ratings are based on responses to the semi-structured interview and a review of collateral information. Items are rated using the PCL-R Rating Booklet and the Quikscore Form obtains scores and profile results. Expanded for use with offenders in several countries, the PCL-R has become the international standard for the assessment of psychopathy. 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. The Manual provides item descriptions, scoring procedures, extensive reliability and validity information, and normative data. Scoring is based on the degree to which a person’s personality/behaviour matches the Rating Booklet items. Ratings are made using a semi-structured interview and a review of collateral information. The PCL-R 2nd Edition is highly reliable and has impressive concurrent, predictive and construct validity. 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. 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. It provides complete coverage of the domain of psychopathic traits and behaviours.

The tool assesses psychopathic personality disorders in forensic populations. The revisions draw upon the large number of of articles, reports, presentations and dissertations that have appeared since the original publication in 1991. With it, you will find forensic assessments of psychopathy to be systematic and based on ironclad data and research. The 2nd Edition of the PCL-R supplants its predecessor as the mandatory tool for assessing psychopathy.
