BackgroundThe current study investigates whether the underlying factor structure of psychopathic personality traits found in adults is similar to that in children and what the extent of the genetic and environmental influences are on these psychopathic traits.MethodPsychopathic personality traits were assessed in a community sample of 1219 twins and triplets (age 9–10 years) through caregiver reports of each child's behavior using the Child Psychopathy Scale (CPS).ResultsConfirmatory factor analyses revealed an optimal two-factor solution (callous/disinhibited and manipulative/deceitful) to the CPS subscales. Bivariate genetic modeling of the two computed factor scores revealed significant genetic as well as unique environmental influences on psychopathic personality traits in both boys and girls, with heritability estimates of 0.64 and 0.46, respectively, in boys and 0.49 and 0.58, respectively, in girls. No shared environmental influences on psychopathic personality traits were found.ConclusionsThe relationship between the two factors was mediated by both genetic and unique environmental factors common to both traits.

Although those currently serving prison sentences for sexual violence can be identified and receive treatment, the number of prisoners with a history of sexual violence against female partners is unknown. Methods to identify prisoners with a proclivity for such violence and accurately assess the risk they pose before and after incarceration are therefore required. Here, we aimed to assess the level of sexually violent attitudes within dating relationships and to examine their associations with experiences of child abuse and neglect (CAN), psychopathic personality traits, prisonization, number of incarcerations, age, years of schooling, relationship status, and parenting among different types of offenders (financial crime, property crime, general violent, and homicide offenders). Data were collected among a large systematically selected sample of adult male inmates ( N = 1,123). We demonstrated that sexual violence-supportive attitudes appear to be a function of child sexual abuse and psychopathic personality traits, and may be developed through early socialization experiences as well as incarceration. Practical implications of current findings are discussed.

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.
