[Quantitative detection of dyssocial and psychopathic personalities in criminal expert assessment. Retrospective study of the value of the German version of the Hare Psychopathy Checklist].

Abstract

In 1980, the Hare Psychopathy Checklist (PCL), an operationalised rating scale for the quantitative assessment of "psychopathy" as seen in the Anglo-American literature, was developed by R.D. Hare in Canada. It proved to be the most valid prognostic instrument for assessing relapse of criminals in English-speaking countries. This study was aimed at verifying the applicability of a German version of the revised PCL (PCL-R) on carefully selected subjects from the Forensic Psychiatric Department of the Psychiatric University Hospital in Munich. Two groups with an equal number of different forensic-psychiatric reports were evaluated retrospectively using the PCL-R. The results confirm the applicability of the PCL-R for the assessment of psychopathy in our sample population. One can expect that the positive experiences with the PCL-R abroad can be transferred to German conditions. The results are encouraging as to the practicability of the PCL-R as a prognostic instrument in routine forensic assessment.
