Available research suggests the neurobiological systems reflected in Reinforcement Sensitivity Theory (RST) are important in etiological conceptualizations of psychopathy, however few studies have utilized the revised RST model (r-RST). Moreover, very little research has examined the associations between r-RST systems and the triarchic psychopathic constructs of boldness, meanness, and disinhibition. Using a recently developed measure of r-RST (Jackson Five; Jackson, 2009), the present study examined the triarchic conceptualization of psychopathy in relation to r-RST in a sample of 301 adult participants. Results suggest that the triarchic construct of boldness is characterized by increased r-BAS activity and deficits in r-FFFS activity; meanness is associated with increased r-BIS and r-Fight activity, and diminished r-BAS, r-Flight, and r-Freeze activity; and, disinhibition is characterized by increased r-BAS, r-Fight, and r-Freeze, with deficits in r-Flight. These results add to our understanding of how the triarchic constructs relate to r-FFFS and r-BAS, however they raise several questions concerning the construct validity of r-BIS as measured by the Jackson Five.
