The abbreviated psychopathy measure-2: Associations with normal-range and maladaptive personality traits

Abstract

Background: The aim of the study was to validate an updated form of the Abbreviated Psychopathy Measure which is based on the triarchic model of psychopathy. Revisions were made to improve indexing of the triarchic scales. The study focused on examining the relationships between the APM-2 scales with lower-order personality traits associated with psychopathy, as well as with antisocial intent, a correlate of antisocial behavior. Participants and Procedure: A convenience sample of participants (N = 190) was recruited from Amazon's Mechanical Turk (MTurk). Construct validity of the APM-2 scales was examined using Pearson's r correlation and multiple regression analyses to determine the relationships between APM-2 scales and criterion measures. Results: The APM-2 Total score was associated at moderate to high levels with core personality features associated with psychopathy. APM-2 Boldness was associated with both positive adjustment (social potency, emotional stability), and negative adjustment (both dangerous and calculated sensation seeking). APM-2 Meanness was associated with measures of callousness, hostile aggression, and manipulativeness, as well as with a measure of antisocial intent. APM-2 Disinhibition was associated with measures of impulsive, norm violating behavior, negative emotional disposition, and antisocial intent. Conclusions: The associations between APM-2 scales and personality traits replicated certain key findings reported in the literature regarding psychopathy-relevant traits indexed by the Triarchic Psychopathy Measure (TriPM). Thus, this study provides a preliminary indication, albeit with a limited range of personality and antisocial behavior variables, that the nomological networks of the APM-2 scales may parallel the nomological networks of the TriPM scales.
