Abstract The triarchic psychopathy model has become a popular perspective from which psychopathic personality traits can be understood. Its constructs can be operationalized via multiple methods, including the scales developed for the Minnesota Multiphasic Personality Inventory-2-Restructured Form item pool (MMPI-2-RF; Ben-Porath, Y. S., & Tellegen, A. (2008)/2011. MMPI-2RF: Manual for administration, scoring and interpretation. University of Minnesota Press. doi:10.1037/t15121-000). Early research has supported the validity and reliability of the MMPI-2-RF-Tri scales. However, no study has directly compared the concurrent validity of these indices with that of the Triarchic Psychopathy Measure (TriPM; Patrick, C. J. (2010). Operationalizing the triarchic conceptualization of psychopathy: Preliminary description of brief scales for assessment of boldness, meanness, and disinhibition. Unpublished test manual, Florida State University, Tallahassee). The current study was conducted using a sample of over 1000 university students at a large midwestern university. All participants were administered both the TriPM and the MMPI-2-RF, as well as other concurrent measures relevant to psychopathy. We found that the MMPI-2RF-Tri scale scores yielded similar correlation patterns to the TriPM scores from the same sample. Most notably, we found that there was a negligible difference amongst the boldness convergent associations across the TriPM and MMPI-2-RF-Tri measures. Implications of these findings and limitations of this study are discussed. Keywords TriPM . MMPI-2-RF . MMPI-2-RF tri-scales . Psychopathy
