“Dr. Hare and his associates developed the Psychopathy Check List Revised (PCL-R) and its derivatives which provide a clinical assessment of the degree of psychopathy that an individual possesses (1).
Based on 40 years of intensive empirical research, the PCL-R has been established as a powerful tool for the assessment of this serious and dangerous personality disorder. Specific scoring criteria rate twenty separate items on a three-point scale (0, 1, 2) to determine the extent to which they apply to a given individual.
The instruments developed by Dr. Hare and his colleagues attempt to measure a distinct cluster of personality traits and socially deviant behaviors which fall into four factors: interpersonal, affective, lifestyle and antisocial.
The interpersonal traits include glibness, superficial charm, grandiosity, pathological lying and manipulation of others. The affective traits include a lack of remorse and/or
guilt, shallow affect, lack of
empathy and failure to accept responsibility. The lifestyle behaviors include stimulation-seeking behavior, impulsivity, irresponsibility, parasitic orientation and a lack of realistic life
goals. Antisocial behaviors include poor behavioral controls, early
childhood behavior problems, juvenile delinquency, revocation of conditional release and committing a variety of crimes.
An individual who possesses all of the interpersonal, affective, lifestyle and antisocial personality traits measured by PCL-R is considered a psychopath.”

“Abstract
Background: The triarchic model of psychopathy characterizes the disorder in terms of three distinguishable phenotypic facets: disinhibition, meanness and boldness. The present study sought to (1) inform current debates regarding the role of boldness in the definition of psychopathy and (2)
clarify boundaries between psychopathy and antisocial personality disorder (ASPD).
Method: This study evaluated the degree to which facets of the triarchic model are represented in the most widely used clinical inventory for psychopathy, the Psychopathy Checklist - Revised (PCL-R), in comparison with ASPD as defined by DSM-IV criteria. Adult male offenders from two distinct correctional settings (n = 157 and 169) were investigated to ensure replicability of findings across samples exhibiting high base rates of psychopathy and antisocial behavior.
Results: We found evidence for convergent and discriminant validity of the three triarchic facets in predicting symptomatic components of psychopathy as assessed by the PCL-R. Additionally, and crucially vis-à-vis current debates in the field, we found that boldness contributed incrementally (over and above disinhibition and meanness) to prediction of PCL-R psychopathy, in particular its interpersonal style component, but not ASPD.
Conclusions: The three distinct facets of the triarchic model of psychopathy are represented clearly and distinctly in the PCL-R, with boldness through its interpersonal facet, but not in DSM-defined ASPD. Our findings suggest that boldness is central to diagnostic conceptions of psychopathy and distinguishes psychopathy from the more prevalent diagnosis of ASPD.”
