Initial development of an implicit and explicit approach to assess psychopathy

Area of Science:

• Psychology
• Forensic Psychology
• Clinical Psychology

Background:

• Psychopathy assessment traditionally focuses on explicit traits.
• There is a need for instruments measuring both implicit and explicit psychopathic functioning.
• The Affective, Cognitive and Lifestyle (ACL) assessment was developed to address this gap.

Purpose of the Study:

• To introduce and validate the Affective, Cognitive and Lifestyle (ACL) assessment.
• To examine the ACL's internal reliability and its correlation with the Psychopathy Checklist-Screening Version (PCL-SV).
• To explore the relationship between implicit affect, cognition, and psychopathy.

Main Methods:

• Four studies involving students, young prisoners, and forensic psychiatric patients were conducted.
• Participants completed the ACL assessment and the PCL-SV.
• Internal reliability of the ACL was assessed, and correlations between ACL components and PCL-SV factors were analyzed.

Main Results:

• The ACL demonstrated evidence of internal reliability across samples.
• ACL components showed expected correlations with the PCL-SV, though with some sample variation.
• Implicit affect and specific cognitive aspects positively correlated with higher PCL-SV scores.

Conclusions:

• The ACL assessment is a viable tool for measuring psychopathy, encompassing both implicit and explicit aspects.
• Findings support the ACL's utility in research and clinical settings for psychopathy assessment.
• Further research is recommended to explore the nuances of implicit affect across different populations.
