ABSTRACT Emerging research on psychopathy in children and adolescents raises the question of whether indicators, such as temperament or psychophysiology, exist very early in life in those with a psychopathic-like personality in adulthood. This study tests the hypothesis that individuals who are more psychopathic in adulthood would be less fearful and inhibited and more stimulation seeking/sociable at age 3 and that they would also show reduced age 3 skin-conductance (SC) responsivity. In a community sample of 335 3-year-olds, behavioral measures of temperament were taken and electrodermal activity was recorded in response to both orienting and aversive tones. R. D. Hare's (1985) Self-Report Psychopathy scale (SRP-II) was administered at follow-up at age 28. Individuals scoring higher on the measure were significantly less fearful and inhibited, were more sociable, and displayed longer SC half-recovery times to aversive stimuli compared with controls at age 3. Contrary to predictions, they also showed increased autonomic arousal and SC orienting. Findings appear to be the first to suggest that a prospective link may exist between temperament and psychophysiology in very young children and psychopathic personality in adulthood.

    ABSTRACT: The purpose of this study was to determine whether a subset of items from the 20-item Psychopathy Checklist-Revised (PCL-R) could be used to construct a two-dimensional model (fearlessness, disinhibition) of adult temperament relevant to psychopathy and antisocial behavior. This theory-guided model was created by combining six items from the interpersonal and affective facets of the PCL-R into a single dimension (fearlessness) and taking four items from the lifestyle facet and forming a second dimension (disinhibition). A confirmatory factor analysis performed on a sample of 2753 adult offenders and forensic patients was used to compare the two-dimensional model to several alternate models. The results indicated that the two-dimensional model achieved a significantly better fit than a one-dimensional model and demonstrated better absolute fit than the traditional two-, three-, and four-factor models and the recently proposed triarchic model of psychopathy. In addition, latent factor scores derived from both dimensions of the two-dimensional model displayed incremental validity relative to Facet 4 (antisocial) of the PCL-R in predicting subsequent offending. These findings indicate that a theoretically derived two-dimensional model of temperament may be of assistance in clarifying psychopathy and other crime-related constructs.

    ABSTRACT: Antisocial personality disorder (ASPD) and psychopathy are 2 important syndromes with substantial utility in predicting antisocial behavior. Although prior studies have identified correlations between various factors and the presence of psychopathy or ASPD, most studies have focused on 1 syndrome or the other. Consequently, it is unclear whether the 2 syndromes reflect similar pathophysiologies, whether they are in fact 2 distinct syndromes, or whether the correlates of ASPD reflect its high comorbidity with psychopathy. The present study addressed this issue by examining the impact of ASPD with and without comorbid psychopathy (as assessed by the Psychopathy Checklist-Revised) on criminal offending and cognitive processing in 674 adult male inmates at a county jail in Illinois. Participants exhibited either ASPD and comorbid psychopathy, ASPD but not psychopathy, or neither ASPD nor psychopathy. Participants with and without comorbid psychopathy were characterized by more criminal behavior than controls, and inmates with ASPD and psychopathy exhibited more severe criminal behavior than those with ASPD only. In addition, inmates with ASPD and psychopathy exhibited a different pattern of cognitive task performance impairment than those with ASPD alone. Results replicate the findings of Kosson, Lorenz, and Newman (2006) and provide new evidence suggesting that men with ASPD and comorbid psychopathy are characterized by cognitive processing anomalies different from those seen in ASPD without comorbid psychopathy.

    ABSTRACT: Introduction Psychiatric disorders can start at a very young age, though prevalence of specific disorders change over time. Consequently, any study of continuities and discontinuities should start in infancy, and core concepts of developmental psychopathology are useful for understanding the data. Violence is a major societal problem, while the most effective intervention is to prevent the developmental, normative aggression in very early childhood, from turning into conduct disorders and antisocial personality disorders later in life. The aims of this study were to apply the core concepts of developmental psychopathology to the understanding of the data about how developmental aggression in infancy may turn into pathological violence and conduct disorders in childhood and then into psychopathology in adulthood.Methods Selective computerized review of the literature examining longitudinal studies of aggression and violence from infancy to adulthood was conducted.Results Pathways of continuity and discontinuity of aggression and violence were identified from infancy into adulthood. Early care-giving quality is a major contributor to the outcomes, but additional risk and protective factors are in a dynamic and complex interplay. The longer a pathway is pursued, the more difficult change becomes.Discussion Intervention programs aimed at reducing violence among individuals and societies should target risk and protective factors, at least as much as the symptoms.
