Further evidence of the divergent correlates of the Psychopathic Personality Inventory factors: prediction of institutional misconduct among male prisoners.
Recent evidence suggests that 2 largely orthogonal dimensions underpin the latent construct assessed by the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996): Fearless Dominance (PPI-I) and Impulsive Antisociality (PPI-II). Relatively few data exist on the correlates of these 2 dimensions in offender samples, however. The present study examines the criterion-related validity of these 2 dimensions among male prison inmates (N = 131) in relation to the prediction of 3 categories of institutional maladjustment: aggressive misconduct, nonaggressive misconduct, and any misconduct. PPI-II significantly predicted each criterion type, with effect sizes of moderate magnitude, whereas PPI-I was essentially unrelated to these outcome measures.
