The validity of the psychopathic personality inventory--revised in a community sample.
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 in a community sample (N = 675). First, confirmatory factor analyses did not support the two-factor structure. Second, the PPI-R factors showed good convergent and discriminant validity with two other self-report measures of psychopathy, that is, the Youth Psychopathic Traits Inventory and Levenson's Self-Report of Psychopathy. Third, PPI-R factors exhibited good external validity in relation to various theoretically relevant correlates. 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.

Low defensive cardiac reactivity as a physiological correlate of psychopathic fearlessness: Gender differences.

Affective/interpersonal features of psychopathy have been consistently associated with diverse psychophysiological indicators of low threat sensitivity, suggesting an underlying deficit in the reactivity of the brain's defensive motivational system. This study examined the Cardiac Defense Response (CDR) -a complex pattern of heart rate changes in response to an aversive, intense, and unexpected stimulus- and its second accelerative component (A2), as a new physiological indicator of the fearlessness trait component of psychopathy. The differential contribution of dispositional fearlessness, externalizing proneness, and coldheartedness to the CDR pattern elicited during a defense psychophysiological test was examined in a mixed-gender sample of 156 undergraduates (62% women) assessed by the Psychopathic Personality Inventory-Revised (PPI-R).

Objectives: Eosinophilic esophagitis (EoE) is a chronic esophageal disease characterized by eosinophilic inflammation. Proton-pump inhibitors (PPI) induce disease remission but no predictive factors of PPI-responsiveness have been identified yet. So, a biomarker must be found to differentiate between responders (PPI-R) and nonresponder patients (PPI-NR) to PPI.

Methamphetamine use and psychopathy are associated with criminal behavior; however, it is unclear how methamphetamine use and psychopathy interact to promote violent, economic and drug offenses. Abnormalities in corticostriatal functional connectivity are exhibited in both psychopathic and methamphetamine dependent individuals, which may contribute to criminal behavior through maladaptive and impulsive decision-making processes. This study shows that psychopathic traits contribute to weaker corticostriatal connectivity in methamphetamine dependence and contributes to an increase in criminal behavior.

Event-related potentials (ERPs) were used to assess the neural mechanisms underlying visual-spatial attention abnormalities associated with psychopathic personality traits. Sixty-nine undergraduates (56 women, 13 men) completed the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005) and performed two cognitive tasks in which search displays containing a lateralized singleton encircled a fixation point that changed luminance from trial-to-trial. When searching for the singleton as a target, PPI-R scores were uncorrelated with ERP measures of its salience (Ppc), goal-directed selection (N2pc), and working memory evaluation (negative amplitude CDA).

Aims: This exploratory study is the first to examine previously identified variables of increased vulnerability to victimization, the prevalence of aggression in a cohort of patients with first-episode psychosis and the potential impact of impairments in facial affect recognition (FAR) on victimization.
Methods: Sixty-nine male participants completed assessments of IQ, substance use, psychopathy, childhood trauma, aggressive behaviour and psychopathology. Participants were asked about violent victimization in the past year and charges for violent offences.
