Abstract (Summary)

There is limited literature available on the lived experience of psychopathic individuals who score in the 36.75-40 range on the Hare Psychopathy Checklist Revised (PCL-R), hereafter termed Extreme Psychopathy (EP). This qualitative study shows how the characteristics described in quantitative studies of psychopathic individuals manifest in the lives of real people identified with Extreme Psychopathy. Nine of 317 PCL-R assessments conducted between 1995 and 2009 by the researcher scored in the Extreme Psychopathy range. This research with embedded units focuses on the archival records of the three of these individuals who are deceased. Each case history is a critical test of Hare's construct of psychopathy. A thematic analysis was used to explore similarities and differences within and across case histories. These case histories demonstrate the life course perspectives and individual permutations of the 20 items of the PCL-R, uniquely portraying individuals in the Extreme Psychopathy range. It is recommended the term "Extreme Psychopathy" apply to individuals with PCL-R Total Scores falling within one SEM from the maximum score of 40.
