The Relationship between Serotonergic Function and the Psychopathy Checklist: Screening VersionAdult Forensic Mental Health Services, Mental Health Services of Salford and Department of Psychiatry, University of Manchester, Manchester, UK.
Neuroscience and Psychiatry Unit, The University of Manchester, Manchester, UK. Reduced serotonergic (5-HT) neurotransmission has been reported in impulsive and aggressive personality disordered and offender samples. What is not clear is the relationship between 5-HT function and the North American construct of psychopathy assessed using the Psychopathy Checklist and its derivatives, which emphasizes the core interpersonal/affective as well as behavioural components of this syndrome. Fifty-one DSM-III-R personality disordered offenders who had a dynamic assessment of 5-HT function (prolactin response to 30 mg d-fenfluramine challenge) were rated on the Psychopathy Checklist: Screening Version based on interview and file data. The Psychopathy Checklist: Screening Version (PCL: SV) mean score in the sample was similar to other reports in European forensic samples. A three-factor structure best explained the PCL: SV data: arrogant/deceitful, callous-unemotional and impulsive-antisocial behaviour factors. 5-HT function did not correlate with psychopathy as a unidimensional phenomenon. The impulsive-antisocial component correlates negatively with 5-HT function while the arrogant/deceitful component correlates positively with 5-HT. In line with previous research findings, impulsive-antisocial conduct shows an inverse relationship with 5-HT function. Arrogant/deceitful traits correlate positively with 5-HT function and may be an adaptive component of psychopathy.
