Two correlated factors have been identified in the Psychopathy Checklist (PCL), a valide and reliable instrument for the assessment of psychopathy in male prison populations. Factor 1 measures a selfish, remorseless, and exploitative use of others, and Factor 2 measures a chronically unstable and antisocial life-style. We examined the psychometric properties of the factor solutions and a variety of correlates of the two factors 
Criterion-Related Validity of the Three-Factor Model of Psychopathy
The validity of this newer three-factor model of the PCL-R factors with reference to external criteria from the domains of personality, antisocial behavior, and adaptive functioning is evaluated in a sample of 310 incarcerated offenders to support the convergent and discriminant validity of these psychopathy facets.
Psychometric Properties of the Psychopathy Checklist
The Portuguese version of the PCL:YV demonstrated promising psychometric properties of the three-factor model of youth psychopathy, internal consistency, convergent validity, concurrent validity, and retrospective validity that generally justify its use among Portuguese youths.
Factor Structure of Psychopathy in Youth
Psychopathy has traditionally been viewed as a two-factor construct composed of core personality and antisocial features. This two-factor model was called into question by Cooke and Michie.
The Validity of the Psychopathic Personality Inventory—Revised in a Community Sample
The results indicate that the PPI-R factors have good convergent, discriminant, and external validity, but confirmatory factor analysis raises concerns about the robustness of the two-factor structure.
Adolescent Psychopathy
This study compared five proposed factor models of psychopathy in a sample of 227 adolescent incarcerated offenders and psychiatric inpatients. Results of confirmatory factor analysis indicated that
Adolescent Psychopathy and the Big Five: Results from Two Samples
Results were consistent across age and rating source in supporting the initial hypotheses, providing support for the construct of juvenile psychopathy and the interpretation of psychopathy as a constellation of traits drawn from a general model of personality functioning.

Revised in a Community Sample − − The Validity of the Psychopathic Personality Inventory
Research on the Psychopathic Personality Inventory–Revised (PPI-R) has revealed two factors: Fearless Dominance, and Self-Centered Impulsivity. This study examined the validity of these PPI-R factors
Dimensions of Psychopathy: A Factor Analytic Study of the MMPI Antisocial Personality Disorder Scale
We reviewed the current models of psychopathy that include both diagnostic systems (DSM-II, DSM-III, DSM-III-R, PCL) and psychometric methods (MCMI-II and MMPI). We focused on the recently developed
The Psychopathy Q-Sort
Self- and observer prototype correlations generally displayed predicted patterns of convergent and discriminant validity for the psychopathy Q-Sort, and future research using the PQS should focus on potential domains of incremental validity of peer-rated psychopathy beyond self-reported psychopathy.


Psychopathy and structure of primary mental abilities
The Comprehensive Ability Battery (CAB) was used to assess 18 primary mental abilities in 53 white, male prison inmates for whom highly reliable ratings of psychopathy were available. None of the
Narcissism: theory and measurement.
The Exploitiveness/Entitlement subscale was found to correlate with measures of pathological narcissism and affective intensity and variability and the relevance of Linville's (1982) theory of self-complexity-affect intensity for understanding aspects of narcissism is outlined.
A principal-components analysis of the Narcissistic Personality Inventory and further evidence of its construct validity.
Evidence is found for a general construct of narcissism as well as seven first-order components, identified as Authority, Exhibitionism, Superiority, Vanity, Exploitativeness, Entitlement, and Self-Sufficiency, in the Narcissistic Personality Inventory.
Psychopathy and physiological responses to threat of an aversive stimulus.
Physiological activity was monitored while 64 prison inmates awaited delivery of a 120dB tone during a 12-sec “count-down” procedure and were interpreted as a reflection of an association between psychopathy and the operation of efficient mechanisms for coping with threat.

A strong association was found between So scores and the quality of parental care which patients reported receiving from their fathers, and with a clinical diagnosis of personality disorder.
The internal consistency and factorial structure of behaviors judged to be associated with DSM-III personality disorders.
Most sets of criteria were internally consistent, but items relating to different disorders showed substantial intercorrelations, and factor analysis identified specific traits rather than actual disorders.

The immediate stimulus for developing a test of narcissism was the inclusion of a new category, the narcissistic personality disorder, in the diagnostic manual (DSM-111) being prepared by the
