Examining the Item-Level Structure of the Triarchic Psychopathy Measure: Sharpening Assessment of Psychopathy Constructs

Abstract

The Triarchic Psychopathy Measure (TriPM) has emerged as a widely used measure for assessing a three-trait model of disinhibition, meanness, and boldness. Building on recent psychometric work, we examined the TriPM’s item-level factor structure and correlates in both a clinically oriented community sample (n = 700) and in undergraduates (n = 527). Our results indicated a replicable three-factor structure generally corresponding with disinhibition, meanness, and boldness, although many items were not clear indicators of their assigned TriPM domain scales. Consequently, these dimensions may be better represented by Alternate Disinhibition (14 items), Boldness (13 items), and Meanness (8 items) domain scales. Additionally, we identified sets of items defining distinct Self-Assurance and Fearlessness dimensions within Boldness and Irresponsibility and Impulsivity dimensions within Disinhibition. We discuss these findings in the context of other recent studies examining the TriPM’s item-level structure, highlighting key future directions for sharpening measurement of the externalizing spectrum.
