Note. Shaded entries denote hypothesized relationships. Bolded coefficients are significant at p<.001. Zero-order correlations (r) reflect bivariate correlations for each PPI-Triarchic subscale score with criterion measure. Standardized regression coefficients (β) are from regression models incorporating all three PPI-Triarchic scales as predictors of criterion measures. Model R = Multiple R from these regression models. PPI = Psychopathic Personality Inventory; TriPM = Triarchic Psychopathy Measure; MPQ = Multidimensional Personality Questionnaire; FD = Fearless Dominance; IA = Impulsive Antisociality; NEO-PI-R = NEO Personality Inventory – Revised; ICU = Inventory of Callous-Unemotional Traits.
