In Study 2, we explored the construct validity of these psychopathy measures in college student and correctional samples. We estimated psychopathy scores by regressing PPI scores onto conceptually selected MMPI-2-RF scales in a combined sample of 825 college students and correctional inmates. In Study 1, we describe the development of such indices referenced to the Psychopathic Personality Inventory (PPI Lilienfeld & Andrews, 1996) and its two distinguishable facets, Fearless-Dominance and Impulsive-Antisociality. This paper reports on three psychopathy indices derived from scores on the MMPI-2 Restructured Form (MMPI-2-RF Ben-Porath & Tellegen, 2008).
