The triarchic model (Patrick, Fowles, & Krueger, 2009) was formulated to reconcile contrasting conceptions of psychopathy reflected in historic writings and contemporary assessment instruments, and to address persisting unresolved issues in the field. The model conceives of psychopathy as encompassing three distinct but interrelated phenotypic dispositions—disinhibition, boldness, and meanness—with biological referents. These dispositional constructs can be viewed as building blocks for alternative conceptions of psychopathy, and various existing psychopathy measures are presumed to index these constructs to differing degrees. This article summarizes the bases of the triarchic model in the conceptual and empirical literatures on psychopathy, and it describes linkages between the constructs of the model and established structural frameworks for personality and psychological disorders. Alternative methods for indexing the constructs of the model are described, and evidence regarding their interrelations and criterion‐related validity is reviewed. Promising aspects of the model for ongoing research on psychopathy are discussed, along with current gaps in knowledge/methods and recommended avenues for future research.
