Background People with psychopathic personality traits have been shown to have low rates of posttraumatic stress disorder (PTSD). Contemporary theoretical models of PTSD and psychopathy converge to suggest that a bias in the type of information that is encoded into memory is a core component of both disorders. We tested the hypothesis that people with psychopathic personality traits have a reduced susceptibility to developing intrusion-related symptoms. Method Participants completed self-report measures before watching a short video depicting the aftermath of a motor vehicle accident. The participants recorded their intrusive memories for seven days before returning for a follow-up assessment. Results Psychopathic personality score was found to be a significant negative predictor of intrusion-related experiences at follow-up. This relationship was mediated by the vividness of intrusions. Conclusion The results support the hypothesis that the balance between the encoding of perceptual versus conceptual properties is a core feature both in the aetiology of PTSD and in people with psychopathic personality traits.

Background. Both psychopathic personality traits and antisocial behavior are influenced by genetic as well as environmental factors. However, little is known about how genetic and environmental factors contribute to the associations between the psychopathic personality traits and antisocial behavior.Method. Data were drawn from a longitudinal population-based twin sample including all 1480 twin pairs born in Sweden between May 1985 and December 1986. The twins responded to mailed self-report questionnaires at two occasions: 1999 (twins 13–14 years old), and 2002 (twins 16–17 years old).Results. A common genetic factor loaded substantially on both psychopathic personality traits and antisocial behavior, whereas a common shared environmental factor loaded exclusively on antisocial behavior.Conclusions. The genetic overlap between psychopathic personality traits and antisocial behavior may reflect a genetic vulnerability to externalizing psychopathology. The finding of shared environmental influences only in antisocial behavior suggests an etiological distinction between psychopathic personality dimensions and antisocial behavior. Knowledge about temperamental correlates to antisocial behavior is important for identification of susceptibility genes, as well as for possible prevention through identification of at-risk children early in life.

There are currently many alternative self‐report inventories for the assessment of antisocial and psychopathic personality traits. The hypothesis of the current study was that similarities and differences among them can be meaningfully understood with respect to their representation of common personality traits. The current study explored this hypothesis using as a point of comparison the Five Factor Model (FFM) of general personality functioning. Six self‐report measures currently being used in antisocial and psychopathy research were administered, along with a self‐report measure of the FFM. Differences were obtained across the six inventories with respect to how they related to the domains and facets of the FFM that were consistent with FFM models of psychopathy and antisocial personality disorder. Implications for the theoretical and clinical understanding of findings obtained with the respective inventories, and the personality disorder constructs they assess, are discussed.

Abstract.Narcissism is seen as a multidimensional construct that consists of two manifestations: grandiose and vulnerable narcissism. In order to define these two manifestations, their relationship to personality factors has increasingly become of interest. However, so far no studies have considered the relationship between different phenotypes of narcissism and personality factors in adolescents. Method: In a cross-sectional study, we examine a group of adolescents (n = 98; average age 16.77 years; 23.5 % female) with regard to the relationship between Big Five personality factors and pathological narcissism using self-report instruments. This group is compared to a group of young adults (n = 38; average age 19.69 years; 25.6 % female). Results: Grandiose narcissism is primarily related to low Agreeableness and Extraversion, vulnerable narcissism to Neuroticism. We do not find differences between adolescents and young adults concerning the relationship between grandiose and vulnerable narcissism and personality traits. Discussion: Vulnerable and grandiose narcissism can be well differentiated in adolescents, and the pattern does not show substantial differences compared to young adults.
