Examining the Triarchic Psychopathy Measure and Comprehensive Assessment of Psychopathic Personality in Self-Identified Offender Populations

Despite the clear clinical and forensic importance of psychopathy, definitions of psychopathy and the optimal measurement of the disorder are issues of continued controversy. The present research provides an empirical examination of two self-report instruments indexing recent conceptualizations of psychopathy: the Comprehensive Assessment of Psychopathic Personality-Self-Rating Scale (CAPP-SR) and Triarchic Psychopathy Measure (TriPM). This study provides the first examination of the convergence between the two tools, and the first investigation into the criterion-related validity of the CAPP-SR within a self-identified offender population. Our findings suggest strong support for the criterion-related validity of the CAPP-SR and the convergent validity of the CAPP-SR and the TriPM Meanness and Disinhibition domains. TriPM Boldness exhibited a clearly bifurcated pattern of association with all outcome criteria as compared with all domains in the CAPP model, and the Meanness and Disinhibition domains of the TriPM. Further, TriPM Boldness did not add incrementally or interact with Meanness or Disinhibition to predict the majority of outcomes. Findings are discussed with respect to the relevance of TriPM Boldness in the conceptualization of psychopathy, and the possible contributions of the CAPP-SR to the field of psychopathy research and assessment.
