Can the Comprehensive Assessment of Psychopathic Personality Be Used to Measure the Triarchic Model Constructs of Boldness, Meanness, and Disinhibition? A Scale Derivation Study.

Abstract

Can the components of the triarchic model of psychopathy (i.e., boldness, meanness, disinhibition) be operationalized using the item pool comprising the Comprehensive Assessment of Psychopathic Personality (CAPP) model? To address this question, the authors first derived CAPP-based triarchic scales using standard item-selection procedures and then examined the external correlates of these provisional scales in three archival data sets: (a) U.S. jail inmates administered the institutional rating scale version of the CAPP and (b and c) prototypicality ratings of the CAPP traits provided by Swedish forensic mental health professionals and U.S. probation officers. Although most research on triarchic constructs has relied exclusively on self-report inventories, the results suggest that the CAPP model can be reorganized to reflect boldness, meanness, and disinhibition and that its institutional rating scale items can effectively quantify these constructs using interview and file review data. Implications for future research on the measurement and assessment of psychopathic traits are discussed.
