Examining hypothesized interactive and curvilinear relations between psychopathic traits and externalizing problems in an offender sample using item response-based analysis.

Fearless dominance (FD) generally manifests null to small relations with externalizing problems, leading some researchers to propose alternative paths by which FD features may relate to these problems. The current study provides a test of two possibilities, namely that FD (a) interacts statistically with self-centered impulsivity (SCI) such that FD is associated with externalizing problems only at high levels of SCI and (b) demonstrates...
