Psychopathy and impulsivity: The relationship of the triarchic model of psychopathy to different forms of impulsivity in offenders and community participants

- Meanness related to all forms of UPPS-P impulsivity
- Boldness related to low negative urgency, but high sensation seeking/perseverance
- Disinhibition related to high negative/positive urgency, and poor planning
- Correlations did not differ across forensic and non-forensic samples.

Psychopathic individuals are considered to be impulsive, but impulsivity is a multifaceted construct (including positive and negative urgency, lack of planning, lack of perseverance, sensation seeking). We investigated the relationships between the Triarchic Psychopathy Model (TriPM), conceptualising psychopathy in terms of: Boldness, Meanness, and Disinhibition, and UPPS-P Impulsivity. Prison and community participants were examined to assess for consistency in relationships between psychopathic traits and impulsivity across these samples. Boldness related to high sensation seeking, but to low negative urgency and strong perseverance. Disinhibition related to high levels of negative/positive urgency, and poor planning. Meanness was linked to most forms of impulsivity. While the samples showed small differences (higher Sensation Seeking for the community sample, and greater TriPM Disinhibition for the offenders), there were no differences in the relationships between TriPM and UPPS-P. The findings support the dimensional model of psychopathy and demonstrate that some aspects of psychopathy are related to reduced impulsivity. This might explain why some psychopathic offenders are able to commit instrumental violence or criminal behaviour that requires a high level of planning and persistence.
