Abstract

Psychopathy is a personality disorder characterized by a collection of pathological traits that include deficits in affective and interpersonal functioning as well as various behavioral problems. The Triarchic Model of Psychopathy was recently proposed as a means of capturing the phenotypic variance of the disorder with the constructs of meanness, boldness, and disinhibition. The purpose of the present study was to examine the triarchic factors of psychopathy in relation to the MMPI-2-RF in a sample of 139 incarcerated male offenders. We used exploratory structural equation modeling to identify the triarchic constructs with indicators that included the 4 facets of the Psychopathy Checklist-Revised, 8 content scales of the Psychopathic Personality Inventory-Revised, and the 3 scales of the Triarchic Psychopathy Measure. The model exhibited mediocre fit (CFI=.91, RMSEA=.10, SRMR=.045); the factor loadings conformed to a conceptually accepted pattern. As such, this model was accepted as a latent representation of the triarchic psychopathy model. MMPI-2-RF scales were related to the triarchic factors in a conceptually relevant fashion. Boldness was associated with markers of low negative emotionality, social dominance, and low fear. Disinhibition was associated with antisocial behavior, high levels of negative emotionality, and poor behavioral control. Although the results for meanness were not as strong as the other two factors, it was nevertheless associated to a moderate degree with high levels of aggression, anger proneness, and a lack of interpersonal attachment. Overall, our results suggests that the triarchic model of psychopathy can be captured well using the MMPI-2-RF.
