Fearless Dominance and Self-Centered Impulsivity Interact to Predict Predatory Aggression among Forensic Psychiatric Inpatients

Testosterone dynamics and psychopathic personality traits independently predict antagonistic behavior towards the perceived loser of a competitive interaction

“…We found some evidence of this interaction; the relationship between fearless dominance and antagonistic behavior was strongest in women lower rather than higher in self-centered impulsivity. Nevertheless, this interaction was in a direction opposite to that reported by Smith et al (2013) in which higher scores on both factors best predicted aggression. The interaction reported here also failed to meet statistical significance when it was tested in a larger model with all of the predictors included.…”

Development and validation of triarchic psychopathy scales from the Multidimensional Personality Questionnaire.

“…PCL-R scores were also available for the correctional sample, and analyses revealed a clear preferential relationship for MPQ Boldness with the Interpersonal facet of PCL-R Factor 1, encompassing charm, grandiosity, manipulation, and deceitfulness. These findings for narcissism and interpersonal features of psychopathy provide further support for the claim that high boldness is associated with maladaptive as well as adaptive tendencies (Lilienfeld et al, 2012; Patrick, Venables, & Drislane, 2013) and for the more general claim that interpersonal dominance may be predictive of adverse outcomes (e.g., violence, poor treatment response) even though the construct itself may not appear overtly pathological or correlate strongly with traditional indicators of antisocial personality traits (Edens, 2009; Smith, Edens, & McDermott, 2013). …”

A Triarchic Model Analysis of the Youth Psychopathic Traits Inventory

“…Residual scores computed in this manner would allow for enhanced flexibility in evaluating bivariate associations between YPI-Boldness and external criterion measures, and allow for the incorporation of YPI-Boldness as an indicator in multivariate structural models, or testing for interactions between YPI-Boldness and disinhibitory/externalizing tendencies in the prediction of clinical outcomes (cf. Smith, Edens, & McDermott, 2013), for example. 5 Developing effective measures of boldness is important given ongoing debates regarding the importance of boldness in classic and contemporary conceptions of psychopathy (Lilienfeld et al, 2012;Marcus, Fulton, & Edens, 2013;Miller & Lynam, 2012), and recent work suggesting a role for boldness in distinguishing psychopathy from DSM-defined antisocial personality disorder (Venables, Hall, & Patrick, 2014).…”
