Abstract [en]

The current study employed a large representative sample of violent male offenders within the Swedish prison system to examine the factor structure of the PCL-R and the latent variable relations between the PCL-R items and clinical ratings of low trait anxiety and trait fearlessness (LAF). Consistent with previous research, confirmatory factor analysis (CFA) revealed strong support for the four-factor model of psychopathy (Interpersonal, Affective, Lifestyle, and Antisocial). Also, a series of CFAs revealed that the LAF items could be placed on any of the PCL-R factors without any changes in model fit. Finally, structural equation modeling results indicated that a PCL-R superordinate factor was able to account for most of the variance of a separate LAF factor. Taken together, the results indicate that if low anxiety and fearlessness, as measured via clinical ratings, are part of the psychopathy construct they are comprehensively accounted for by extant PCL-R items.

Abstract [en]

Although psychopathy usually is treated as a unitary construct, a seminal theory posits that there are 2 variants: Primary psychopathy is underpinned by an inherited affective deficit, whereas secondary psychopathy reflects an acquired affective disturbance. The authors investigated whether psychopathy phenotypically may be disaggregated into such types in a sample of 367 prison inmates convicted of violent crimes. Model-based cluster analysis of the Revised Psychopathy Checklist (PCL–R; R. D. Hare, 2003) and trait anxiety scores in the psychopathic subgroup (n = 123; PCL–R ≥ 29) revealed 2 clusters. Relative to primary psychopaths, secondary psychopaths had greater trait anxiety, fewer psychopathic traits, and comparable levels of antisocial behavior. Across validation variables, secondary psychopaths manifested more borderline personality features, poorer interpersonal functioning (e.g., irritability, withdrawal, poor assertiveness), and more symptoms of major mental disorder than primary psychopaths. When compared with the nonpsychopathic subgroup (n = 243), the 2 psychopathic variants manifested a theoretically coherent pattern of differences. Implications for etiological research and violence prevention are discussed.

Abstract [en]

Psychopathy describes a collection of personality traits that logically would facilitate violent, criminal behavior. This dissertation deals with issues that might shed light on how to treat or prevent this socially devastating personality disorder: the conceptualization of the disorder; how psychopathic offenders compare with nonpsychopathic offenders; and whether there are some psychopathic offenders who might be more amenable to treatment than others. The four studies use data from a sample of about 400 violent offenders who were assessed in a national prison unit. The first study dealt with the definition of psychopathy. Using exploratory and confirmatory factor analyses of PCL-R scores, we compared the traditional 17- item, two-factor model with a more recently proposed 13-item, three-factor model. Exploratory factor analysis showed that the 13 items yielded three easily interpretable factors: an interpersonal factor, an affective factor, and a behavioral/lifestyle factor. Confirmatory factor analysis showed that this model had a significantly closer fit to the data than the traditional 17-item, two-factor model. The second and third studies compared psychopathic with nonpsychopathic offenders. In the second study we tested whether psychopathic more than nonpsychopathic offenders had histories of hyperactivityimpulsivity- attention problems (HIA) and conduct problems (CP). We used their retrospective reports of conduct problems before the age of 15 and HIA before the age of 10. The results showed that a combination of childhood HIA and CP was typical for psychopathic but not nonpsychopathic offenders. The third study tested the hypothesis that intelligence is positively correlated with severity of criminal development in psychopathic criminals and negatively correlated in nonpsychopathic criminals. That pattern would provide a way of explaining the discrepancy between Cleckley’s view and later empirical work and open the door to new ideas about prevention and treatment. For non-psychopaths, higher total intelligence scores, particularly verbal intelligence, meant a later start in violent crime. For those diagnosed as psychopaths, however, this association was reversed. The fourth study investigated whether meaningful subtypes of psychopathy could be identified. Model-based cluster analysis of Revised Psychopathy Checklist (PCLR Hare, 2003) and trait anxiety scores in the psychopathic subgroup (n = 124; PCL-R > 29) revealed two clusters, which we labeled primary and secondary. Secondary psychopaths had greater trait anxiety and fewer psychopathic traits than primary psychopaths, but comparable levels of antisocial behavior. They also had more borderline personality features, poorer interpersonal functioning, and more symptoms of major mental disorder than primary psychopaths. Psychopathy is a complex and in some ways mysterious disorder, and little is known about how it develops. Taken together, these studies provide some clues that might ultimately lead to ways of preventing the development of psychopathy. Early HIA problems apparently put children in a risk group. Apparently, high intelligence plays a role in the most problematic cases, and the disorder can develop in the presence of anxiety. Although the idea is not without problems, adult psychopaths who are high on anxiety might be more amenable to treatment than those who are not.

Abstract [en]

The purpose of the present study was to test whether adult criminals with psychopathy diagnoses, more than those without, have histories of hyperactivity–impulsivity–attention problems (HIA) and conduct problems (CP). We compared psychopathic and nonpsychopathic violent criminal offenders on retrospective reports of conduct problems before the age of 15 and hyperactivity–impulsivity–attention problems before the age of 10. We used a sample of 186 adult men sentenced to prison in Sweden for 4 years or more for violent, nonsexual crimes. The mean age was 30.7(SD = 9.4). The results showed that a combination of childhood HIA problems and CP was typical for adult psychopathic offenders. They were four times more likely than chance to have had a combination of HIA problems and CP during childhood and only one–fifth as likely than chance to have had neither problem. Nonpsychopathic offenders, on the other hand, were five times more likely than chance to have had neither problem and only one-quarter as likely than chance to have had both problems.

Abstract [en]

Empirical studies using the PCL-R (Hare, 2003) have shown no intelligence differences between psychopaths and nonpsychopaths. However, Cleckley (1976) argued that psychopaths often show superior intelligence. The purpose of the present study was to test the hypothesis that the correlation between intelligence and severity of criminal development is the opposite in psychopaths than in nonpsychopathic criminals using a sample of 370 men sentenced for violent (nonsexual) crimes. That pattern would provide a way of explaining the discrepancy between Cleckley's view and later empirical work. The results showed that for nonpsychopaths, higher total IQ and particularly verbal intelligence meant a later start in violent crime. For those diagnosed as psychopaths, however, this association was reversed.

Abstract [en]

OBJECTIVE:

This study is an attempt to compare two alternative models of psychopathy (PCL-R); (i) the traditional 17-item two-factor model where the first factor describes a deceitful, manipulative and callous, unemotional dimension and the second factor describes the impulsive, irresponsible and antisocial behavioral lifestyle dimension; and (ii) a recently proposed 13-item three-factor model involving an interpersonal facet, an affective facet and a behavioral facet.

METHOD:

Exploratory and confirmatory factor analyses of PCL-R scores on a sample of 293 adult male violent offenders were conducted.

RESULTS:

The results of the exploratory factor analysis showed that the 13 items yielded three easily interpretable factors: an interpersonal factor, an affective factor and a behavioral/lifestyle factor. Through confirmatory factor analysis we showed that this model had a significantly closer fit to the data than the classical 17-item, two-factor model of the PCL-R.

CONCLUSION:

The study supports the three-faceted model of psychopathy.
