Psychopathy Spectrum Test

The IDR-PST© is the property of IDR Labs International. The original research was provided by associate professor of psychology Michael R. Levenson. The IDR-PCT utilizes Levenson’s research, but is not associated with Levenson, and is not the equivalent of the Levenson Self-Report Psychopathy Scale. The present test is in no way endorsed by, nor affiliated with, Levenson, Hare, their associates, or similar entities. No infringement is intended by the present test.

The Psychopathy Spectrum Test developed by Professor Michael R. Levenson is a psychological assessment designed to measure psychopathic traits in individuals. Unlike traditional views of psychopathy as a black-and-white diagnosis, Levenson’s approach treats psychopathy as a spectrum, suggesting that psychopathic traits can vary in degree from person to person. His test is based on the idea that many people exhibit traits associated with psychopathy to some extent, and these traits exist on a continuum, rather than being limited to those diagnosed with clinical psychopathy.

Levenson’s model distinguishes between two primary factors: primary psychopathy and secondary psychopathy. Primary psychopathy is characterized by a lack of empathy, shallow emotions, and a tendency to manipulate others for personal gain. Individuals with high primary psychopathy scores are often seen as charming, calculating, and callous, showing little concern for the well-being of others. They tend to exhibit a fearless dominance and a sense of superiority, thriving on control and manipulation without feeling guilt or remorse.

Secondary psychopathy, on the other hand, is associated with impulsivity, emotional instability, and a tendency toward risk-taking behaviors. Individuals scoring high on secondary psychopathy may engage in reckless actions without considering consequences, often driven by anxiety, frustration, or emotional needs. Unlike primary psychopathy, where emotions are shallow, secondary psychopathy involves more intense emotions but with poor regulation and a tendency to act out.

Levenson’s Psychopathy Spectrum Test is often used in both research and clinical settings to better understand the complexity of psychopathic traits. Rather than focusing solely on extreme cases of psychopathy, the test reveals how certain psychopathic characteristics may be present in varying degrees across the general population. This understanding of psychopathy as a spectrum has broadened the scope of how these traits are perceived and has provided a more nuanced view of human personality.

The Psychopathy Spectrum test is a widely-used index and instrument for measuring psychopathic tendencies, traits, and behaviors. The Psychopathy Spectrum test does not address all possible psychopathic orientations and does not purport to accommodate respondents who seek to trick the measure or who fall outside the normal spectrum of psychopathy. Contrary to popular belief, the Psychopathy Spectrum is not the only way of measuring psychopathy. Indeed, the output of the Psychopathy Spectrum 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. To test for these styles in the DSM framework, please consult our Personality Style Test.

Although all are designed to measure psychopathic tendencies and behavior, the IDR-PST© should not be confused with other “Psychopathy Checklist Tests” as authored by alternative research organizations. However, all are professionally-designed personality tests (or inventories) meant for measuring psychopathic tendencies and behavior in relation to psychiatric dispositions in the Western world.
