Indeed, the output of the Psychopathy Checklist overlaps considerably with the narcissistic, borderline, and anti-social personality styles, as found in the alternative theoretical frame utilized in psychiatric manuals, such as the DSM. Contrary to popular belief, the Psychopathy Checklist is not the only way of measuring psychopathy. The Psychopathy Checklist does not address all possible psychopathic identities and does not purport to accommodate respondents who seek to trick the measure or fall outside the normal spectrum of human psychology. The Psychopathy Checklist is a widely-used index and instrument for measuring psychopathic tendencies and behavior. No infringement is intended by the present test.

The present test is in no way endorsed by, nor affiliated with, Hare, his associates, or similar entities. The IDR-PCT utilizes Hare’s research, but is not associated with Hare, and is not the equivalent of the Hare Psychopathy Checklist-Revised (PCL-R). The original research was provided by FBI advisor and criminal psychologist Robert D. The IDR-PCT© is the property of IDR Labs International.
