ABSTRACT H. Cleckley (1976) maintained that psychopaths are relatively immune to suicide, but substantial evidence exists for a relationship between antisocial deviance and suicidal acts. This study was the first to explicitly examine suicidal history among psychopathic individuals as defined by R. D. Hare's (1991) Psychopathy Checklist--Revised (PCL-R). Male prison inmates (N = 313) were assessed using the PCL-R and DSM-III-R and DSM-IV criteria (American Psychiatric Association, 1987, 1994) for antisocial personality disorder (APD), and they completed A. Tellegen's (1982) Multidimensional Personality Questionnaire (MPQ). Presence or absence of prior suicide attempts was coded from structured interview and prison file records. Suicide history was significantly related to PCL-R Factor 2 (which reflects chronic antisocial deviance) and to APD diagnosis but was unrelated to PCL-R Factor 1, which encompasses affective and interpersonal features of psychopathy. Higher order MPQ dimensions of Negative Emotionality and low Constraint were found to account for the relationship between history of suicidal attempts and antisocial deviance, indicating that temperament traits may represent a common vulnerability for both.

    • "Given that shame involves negative evaluation of the self (Tangney & Dearing, 2002), it runs contrary to features of psychopathy such as grandiose sense of self-worth and impression management. On the other hand, studies indicate that the antisocial and behavioral features of psychopathy are positively associated with negative affect (e.g., Hicks & Patrick, 2006; Verona et al., 2001). This research aligns with theories of primary and secondary psychopathy (Karpman, 1941; Skeem et al., 2003), which hold that some psychopathic traits may similarly be positively related to shame (Morrison & Gilbert, 2001).

    ABSTRACT: Remorse has long been important to the juvenile justice system. However, the nature of this construct has not yet been clearly articulated, and little research has examined its relationships with other theoretically and forensically relevant variables. The present study was intended to address these issues by examining relationships among remorse, psychopathology, and psychopathy in a sample of adolescent offenders (N = 97) using the theoretically and empirically established framework of guilt and shame (Tangney & Dearing, 2002). Findings indicated that shame was positively related to behavioral features of psychopathy, whereas guilt was negatively related to psychopathic characteristics more broadly. In addition, shame was positively associated with numerous mental health problems whereas guilt was negatively associated with anger, depression, and anxiety. These results provide empirical support for theory that psychopathy is characterized by lack of remorse (e.g., Hare, 1991), and also underscore shame and guilt as potentially important treatment targets for adolescent offenders.

    • "Although psychopathic traits may be at low levels in the general population, those who are high on the core characteristics of fearlessness and low consideration of others may demonstrate dangerous driving and may require special interventions, given the resistance of psychopathy to treatment. Psychopathy, as measured by widely used and well-accepted instruments like the PCL-R (Hare, 2003) and the PPI-R (Lilienfeld and Widows, 2005), is not a unified construct but appears to incorporate various sub-dimensions (Hicks and Patrick, 2006; Verona et al., 2001). Both the PCL and PPI have been broken down into two main factors. "

    ABSTRACT: In spite of the well-documented connection between personality traits like impulsivity, sensation seeking and fearlessness with aberrant driving behaviors, scarce research exists to examine the association between risky and aggressive driving and psychopathic characteristics, which encompass the above traits. The present investigation examines in two studies the association between specific sub-types of driving misconduct, i.e., unintentional mistakes and deliberate rule violations with psychopathic characteristics, with a focus on the role of levels of fear and anxiety in aberrant driving. Findings support the hypotheses that fearlessness, i.e., the bold, unemotional aspect of psychopathic traits, characterizes drivers who engage in frequent deliberate driving code violations, whereas the more impulsive/antisocial aspect of psychopathy, associated with higher levels of fear and anxiety, is more characteristic of drivers who engage in unintentional mistakes. Fearless features are also associated with higher self-reported driving misconduct and accidents. Study 2 conceptually replicated this finding by showing that mistakes are positively related to high sensitivity to punishment, while violations are negatively related to it. Findings are discussed in light of psychopathy theory and in relation to prevention and intervention. Copyright © 2015 Elsevier Ltd. All rights reserved.

    • "Post-travmatik stress bozukluğu olgularında amigdala yanıtı azalmışken antisosyal olgularda belirgin artmış olduğu Psikiyatride Güncel Yaklaşımlar -Current Approaches in Psychiatry gözlenmiştir. Buna bağlamda psikopatinin duygudurum ve anksiyete bozukluklarına karşı koruyucu etkisi alabileceği iddia edilmiştir (Verona ve ark 2001, Crowe ve Blair 2008). Posteromedial korteks ve medial prefrontal korteksin beynin dinlenme sırasında yüksek aktivite ve hedefe yönelik beyin aktiviteleri sırasında azalmış aktivite gösterdikleri gösterilmiş olup bazal beyin fonksiyonlarını yürüttükleri düşünülmektedir.
