Technical Information

Reference Samples:

The SRP 4 has the largest samples of any self-report psychopathy instrument. The SRP 4 includes three specific North American reference samples:
•    Community (N = 638),
•    College (N = 788),
•    and Offender (N = 304).

Each sample represents a group of individuals who are of particular interest to psychopathy researchers, especially those who study psychopathy via self-report.

Reliability and Validity

With over 150 studies examining the reliability and validity of the SRP, it is one of the most well-researched self-report psychopathy measures on the market.  The SRP 4 has strong internal consistency and a high degree of test-retest reliability.  Tested in both forensic and non-forensic samples, the SRP 4 demonstrates exceptional validity.
