Child molestation and psychopathy: a taxometric analysis

ABSTRACT

Prior taxometric research on child molesters and general sex offenders has produced inconsistent and contradictory results. There are theoretical, practical, and policy reasons, however, to assume that a psychopathy taxon may exist in sex offenders and that a taxometric study might shed light on this issue. The mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent-mode factor analysis (L-Mode) taxometric procedures were employed in three overlapping samples: 188 sex offenders with non-relative child victims, 555 sex offenders with non-relative child or adolescent victims or child incest victims, and a mixed sample of 1404 sex offenders. The taxometric analyses revealed evidence of continuous latent structure in all three samples. These results suggest that psychopathy in sex offenders, child molesters in particular, is organised quantitatively (continuous) rather than qualitatively (categorical).     

A brief measure of the triarchic model of psychopathy among community youths: psychometrics and measurement invariance

ABSTRACT

The development and validation of empirically sound measures that operationalize the Triarchic model of psychopathy among youth is currently in the nascent stage. The present study aimed to examine the psychometric properties of a brief refined measure of the Triarchic model of psychopathy based on the Youth Psychopathic Traits Inventory (YPI-Tri-S) among a mixed-gender school sample of 782 youth (M?=?15.87 years, SD?=?1.72) from Portugal. Confirmatory factor analysis offered support for the theoretically expected three-factor structure. Cross-gender measurement invariance using the present sample and cross-sample measurement invariance of the YPI-Tri-S using a previously collected forensic sample of institutionalized males was established. The YPI-Tri-S showed adequate psychometric properties in terms of discriminant validity, convergent validity, concurrent criterion-related validity, known-groups validity, and internal consistency. Findings indicate that YPI-Tri-S is a valuable brief and psychometrically reliable and valid self-report measure of the Triarchic model of psychopathy for use in diverse samples of youth.     

Aggressive behavior and measurement of psychopathy in female inmates of German prisons--a preliminary study

Studies concerning inmate psychopathy (as measured by Psychopathy-Checklist-Revised, PCL-R; Hare, 1991) have predominantly been concerned with male inmates. This study was the first to look into psychopathy using the PCL-R with the whole required procedure in German prisons with female inmates. The aims of the present study were to gain data about the prevalence of psychopathy in this sample and to examine potential relations between the types and motive of aggression, prosocial behavior and scores on the PCL-R. Sixty female inmates were examined. We obtained a prevalence rate of psychopathy of 17% (N=10, with a cut-off score of 25). Considering a wide range of subtypes of aggressive behaviors, we found that physical proactive, and relational reactive aggression as well as age predicted high scores of psychopathy. However, prosocial or helping behavior was not associated with psychopathy. Implications for diagnostic issues in forensics concerning female prisoners are discussed.     

Adolescent parricide and psychopathy

Most cases of juvenile parricide are believed to be the result of child abuse, yet the vast majority of abused children do not kill their parental abusers. This study explored the role of psychopathy in 10 adolescent parricide offenders tried in adult court who were referred for pretrial psychiatric evaluation. In addition, psychopathological findings, crime-related behaviors, and judicial outcomes are described. Diagnostic and Statistical Manual of Mental Disorders diagnoses, most commonly posttraumatic stress disorder, and chronic, severe child abuse were prevalent. Psychopathic traits were not found to have played a role in the traumatized youths' parricidal behavior. Killings occurred in the family homes, usually through a surprise attack with parent-owned firearms. There was an average of 1.7 victims per event, with fathers being the most likely victim. Bodies were commonly covered or wrapped and moved postmortem. Confessions were often incredible in quality. One half received sentences of 40+ years, and the modal sanction was a life sentence, despite 90% premorbidly described as good youth. Further studies of adolescent parricide are needed to better understand this unusual population.     

Reconciling psychopathy and low self-control

Although both reflect a self-centered, antisocial personality, psychopathy and low self-control have seldom been examined together. This study created scales reflecting both common and unique elements of both constructs, investigated their factor structure, and explained variance in delinquency. Four alternative hypotheses were tested: that low self-control and psychopathy constitute a single construct, that they constitute primary and secondary psychopathy or interpersonal and intrapersonal traits, or that they constitute Antisociality—the tendency to perform antisocial acts—and (low) Self-Direction—the tendency to act in one's long-term beneft. Models containing Antisociality and Self-Direction fit better than alternatives and accounted for substantial variance in offending.     

The role of psychopathy and sexuality in a female serial killer

The case of Aileen Wuornos, executed in Florida for the serial killing of seven men, is studied to determine her degree of psychopathy and the presence or absence of sexuality or sexual sadism as a motivation or gratification for her crimes. The authors, one of whom evaluated the subject shortly before her death, determined that she evidenced a psychopathic personality (PCL-R score 32). She also met DSM-IV-TR criteria for Antisocial Personality Disorder and Borderline Personality Disorder. While her killings ostensibly were carried out during routine acts of prostitution, there was ambiguous evidence that her crimes were sexually motivated or gratifying. Her articulated motivation was robbery and elimination of the witness/victim. After carefully considering all available data, the authors concluded there was no convincing evidence of sexual sadism in either her personal history or her method of committing serial murder, and it remains unclear whether sexual gratification was to some degree a motivating factor in her commission of these offenses. The confluence of early childhood attachment disruptions, severe psychopathy, other personality disorder pathology, and a traumagenic abuse history likely contributed to her having serially murdered seven victims.     

The relationship between psychopathy and moral development in young sex offenders

Abstract

This study examined the relationship between psychopathic traits and moral development (moral judgement and empathy) in 85 Dutch male sex offenders between 13 and 23 years of age. Questions were asked about general life situations, sexual situations with morally relevant features, and questions about the offender's own abuse victim. A weak negative association was found between psychopathy and mature moral judgement, but only when questions involved the offender's own abuse victim. Weak to moderate negative associations were found between psychopathy and cognitive and affective empathy in general and sexual situations, but not in the own abuse victim situations. Further analysis revealed moderate negative associations between psychopathy and affective empathy in the own abuse victim situations, but only when an unfamiliar victim was involved. This is the first study, to our knowledge, showing that juvenile sex offenders with high levels of psychopathy have context-specific moral deficits, and that in this group both cognitive and affective empathy are related to psychopathy.     

The trouble with psychopathy as a general theory of crime

The concept of psychopathy, as defined by Robert Hare, is reviewed with respect to its status as a general theory of crime. A hybrid of the medical pathology model and personality trait approach, the psychopathy concept proposes that a significant portion of serious crime is committed by psychopathic individuals. Hare's version of psychopathy, besides demonstrating weak applicability and a propensity for tautology, is subject to labeling effects, oversimplicity, reductionism, the fundamental attributional error, inattention to context, and disregard for the dynamic nature of human behavior. It is concluded that the psychopathy concept is substantially limited with respect to its ability to describe and clarify general criminal behavior but that it may still have value as a partial explanation for certain types of non-criminal predatory behavior.     

The "untreatability" of psychopathy and hospital commitment in the USA

One argument in support of a public policy of not subjecting persons with psychopathic disorders to civil or criminal commitment is that these disorders do not improve with treatment. This article examines the relationship between the assumption of untreatability of psychopathic disorders and outpatient civil commitment, inpatient civil commitment, and insanity acquittee commitment. Research on the treatability of psychopathy is reviewed and the treatment of conditions co-morbid with psychopathy is considered. Research evidence is insufficient to support the conclusion that psychopathy is improved, worsened or not affected by treatment. Evidence does support effective treatments for conditions that can be co-morbid with psychopathic disorders including impulsive aggression which can be interpreted as a manifestation of psychopathic disorder.The absence of evidence based treatment efficacy for psychopathic disorders is a logical reason for not subjecting individuals with only a psychopathic disorder to involuntary hospitalization. This assumption should not becloud the possibility of treatable co-morbid conditions which may or may not qualify for involuntary hospitalization. Where the primary mental disorder, for which an individual is involuntarily hospitalized, results in behavioral improvement, the continued presence of a psychopathic disorder itself, should not be sufficient reason to continue coerced confinement. Even so, where the primary disorder is incompletely treated, psychopathy can be considered a risk factor when deciding upon the appropriate time for discharge and when formulating a safe and effective after care plan.     

Performance intelligence,sexual offending and psychopathy

Abstract

Previous studies have suggested that offenders have lowered verbal intelligence compared to their performance intelligence. This phenomenon has been linked traditionally to childhood risk factors (e.g. deficient education, abuse and neglect). Substantial discrepancies between performance intelligence quotients (PIQ) and verbal intelligence quotients (VIQ), however, might also point to neurobiological impairments which may be associated with specific types of criminal behaviour. From the files of 133 male hospitalized offenders, PIQ, VIQ, full scale IQ (FSIQ) scores and Psychopathy Checklist–Revised (PCL-R) scores were derived, along with information about their criminal histories. PIQ over VIQ discrepancies were most pronounced in sexual offenders, particularly in those who had committed sexual crimes against adult victims. Furthermore, PIQ as well as PIQ higher than VIQ discrepancies correlated modestly, but significantly, with PCL-R scores. The results suggest that lower verbal compared to visual and spatial abilities may be connected specifically to egocentric and narcissistic personality traits which, in turn, may be involved in raising the risk of sexual offending.     

Youth psychopathy: Differential correlates of callous-unemotional traits,narcissism, and impulsivity

Research supports the validity of the dimensional approach to psychopathy in both children and adults. The occurrence of severe aggressive and antisocial behavior in combination with callous-unemotional traits (CU traits) designates a group of children that is particularly at risk to develop psychopathy. However, most studies did not investigate the role of the remaining psychopathy dimensions (i.e. narcissism and impulsivity) in comparison. The present text reviews the newest developments in the dimensional study of psychopathy in relation to cognition, behavior and affect in clinical and detained child and adolescent samples. Findings support the role of the callous-unemotional dimension (CU traits) in the development of psychopathy. Additionally, they also underscore the importance of the narcissistic and impulsive dimensions for the understanding of psychopathy in children and adolescents and for the identification of different psychopathy profiles. Understanding differential correlates of the underlying dimensions of psychopathy is an important step in formulating interventions for those most at risk.     

Male batterers with and without psychopathy: an exploratory study in Spanish prisons

The aim of this study was to analyze the differential profile of male batterers in prison with and without psychopathy. The sample consisted of 162 perpetrators sentenced for a serious offence against their intimate partner. The prevalence of psychopathy or psychopathic traits, established according to the Psychopathy Checklist-Revised, was about 12%. The psychopathic batterers were younger, more impulsive, more suspicious, and less empathetic and had lower self-esteem than nonpsychopathic batterers. However, the psychopathic batterers were not engaged in intimate femicide more often than were the nonpsychopathic batterers. The severity of the crime was similar in both groups, so it may be attributed to other variables (e.g., substance abuse, intoxication at the time of the offence, violence history, jealousy, etc.). Implications of these results for further research and clinical practice are discussed.     

Child and adolescent psychopathy: A state-of-the-art reflection on the construct and etiological theories

Purpose

There is a growing interest in the identification of psychopathic traits in infancy and adolescence. This effort will enable the development of predictive models of aggressive and violent behavior, in order to intervene effectively both in preventive and therapeutic levels. Several authors have suggested that the presence or absence of psychopathic traits, together with the factors that sustain, maximize or minimize them, can help in the identification of the etiology and developmental trajectories of anti-social individuals.

Materials and Methods

Meta-narrative review of the child and adolescent psychopathy construct.

Results

This state-of-the-art review discusses the concept of child and adolescent psychopathy, taking into account historical and conceptual issues.

Conclusion

Evolutionary Theories can add a major contribution to the understanding of the origins of psychopathic traits.     

Examining psychopathy from an attachment perspective: the role of fear of rejection and abandonment

A key feature of psychopathy, a self-centered orientation towards others and a failure to truly connect, is poorly understood. The attachment framework can be used to examine underlying interpersonal mechanisms. Because of the overall failure to connect, we anticipated, and found, in a large undergraduate sample (n?=?1074) that both affective-interpersonal traits and impulsive-irresponsible psychopathy facets were positively related to attachment avoidance. Different dynamics may underlie this distancing from others, as evidenced by the fact that callous-unemotionality was negatively related to attachment anxiety, whereas grandiose-manipulative and impulsive-irresponsible traits were positively related to attachment anxiety. Although effect sizes were small and are of correlational nature, our results are in line with a dual deficit model that differential developmental trajectories, largely heritable callousness vs. neglecting and abusive parenting, may lead to adult psychopathy. The differentiating role of fear of rejection and abandonment for the psychopathy construct is discussed.     

Collateral report of psychopathy: convergent and divergent validity of the psychopathic personality inventory-short form

Psychopathy is a personality syndrome comprised of interpersonal, affective, and behavioral features that has emerged as a correlate of intimate partner violence perpetration. One commonly used self-report measure of psychopathy is the Psychopathic Personality Inventory-Short Form (PPI-SF). The current study employed a multi-trait, multi-method approach to test convergent and discriminant validity of the measure in partner-violent couples by comparing males’ self-report of psychopathy to the informant report of their female partner (N = 114). It was hypothesized that the female partner report of the male’s psychopathy would be highly correlated with the male report of his own psychopathy, thus providing evidence for the construct validity and interrater reliability of the PPI-SF. Analyses found that male and female reports were correlated significantly on the two major factors of the PPI-SF. Furthermore, the female report explained a significant amount of variance over and above men’s self-report on PAI scales designed to indicate antisocial personality traits.     

Development of the supernormality scale-revised and its relationship with psychopathy

Abstract:  The current research addresses the psychometric and diagnostic qualities of the Supernormality Scale-Revised (SS-R), a self-report measurement. Supernormality is defined as the tendency to systematically deny the presence of common symptoms (e.g., intrusive thoughts). In study 1, the SS-R was administered to forensic patients ( n  = 63), psychiatric patients ( n  = 26), honestly responding students ( n  = 26), and students instructed to fake supernormality ( n  = 20). Findings indicated good test–retest stability, and adequate internal consistency. Furthermore, the SS-R showed overall good predictive and convergent validity. Moreover, the diagnostic accuracy was excellent (sensitivity and specificity being 0.80 and 0.92, respectively). In study 2, 115 (healthy) controls and 32 forensic patients completed the SS-R and the Psychopathic Personality Inventory (PPI) ( J Pers Assess 1996; 66 :488), an instrument measuring psychopathy. Results showed again that the SS-R is a reliable and valid instrument. However, supernormality was not related to psychopathy as measured by the PPI.
