Criminal thinking patterns, aggression styles, and the psychopathic traits of late high school bullies and bully-victims

This study explored the current psychological characteristics and criminal behavior history of individuals who retrospectively reported being bullies, bully-victims, victims, or controls (i.e. neither victims nor bullies) during their last 2 years of high school. College students (n = 960) completed measures of criminal thinking, aggression, psychopathy, and criminal behavior online. We predicted bullies and bully-victims would demonstrate the highest scores for criminal thinking, proactive aggression, psychopathy, and have the most criminal infractions. Bullies and bully-victims had significantly higher scores on criminal thinking, aggression, psychopathy, and criminal behaviors than victims or controls. Additionally, men were significantly higher in criminal thinking, aggression, psychopathy, and had more criminal acts than women. There were no gender by bully group interactions. Logistic regression analyses differentiated bully-victims from bullies. Bully-victims tended to be male, higher in criminal thinking, and higher in reactive aggression. In addition, bully-victims were distinct from victims, showing higher criminal thinking and higher proactive aggression.     

Utilization of emotion cues in male and female offenders with antisocial personality disorder: results from a lexical decision task

Antisocial personality disorder (ASPD) diagnoses have demonstrated good reliability and validity in male offenders. However, there is a paucity of research assessing utilization of emotion cues in ASPD individuals and the extent to which correlates of ASPD in males generalize to females. This investigation examined emotion utilization in incarcerated men and women with and without ASPD using a lexical decision task with emotional and neutral words. The performance of male offenders with ASPD was similar to that of male controls, whereas women with ASPD demonstrated greater emotional facilitation than female controls. Moreover, the number of violent crimes committed by female inmates with ASPD was related to emotion facilitation, suggesting a link between their sensitivity to emotion cues and antisocial behavior.     

The Emotional Lexicon of Individuals Diagnosed with Antisocial Personality Disorder

This study investigated the specific emotional lexicons in narratives created by persons diagnosed with antisocial personality disorder (ASPD) to test the hypothesis that individuals with ASPD exhibit deficiencies in emotional language. Study participants consisted of 60 prison inmates with ASPD, 40 prison inmates without ASPD, and 60 men without antisocial tendencies who described situations involving love, hate and anxiety depicted by photographs. The lexical choices made in the narratives were analyzed, and a comparison of the three groups revealed differences between the emotional narratives of inmates with ASPD, inmates without ASPD, and the control group. Although the narratives of the individuals with ASPD included more words describing emotions and higher levels of emotional intensity, the valence of these words was inappropriate. The linguistic characteristics of these narratives were associated with high levels of psychopathy and low emotional reactivity.     

Die Antisoziale Persönlichkeitsstörung des DSM-IV-TR - Befunde, Untergruppen und Unterschiede zu Psychopathy

The diagnosis of Antisocial Personality Disorder (ASPD) is based on robust scientific evidence identifying a group of individuals who display antisocial behaviour from a very young age that remains stable across the life-span. This population of persons with ASPD is heterogeneous, composed of distinct sub-types defined by comorbid disorders. Evidence indicates that ASPD is distinct from both psychopathy, as defined by the PCL-R, and from Dissocial Personality Disorder, as defined by ICD-10. Studies of the prevalence of ASPD are reviewed, highlighting the difficulties inherent in designing and conducting investigations of community samples that derive accurate estimates. The few studies of the socio-demographic correlates of ASPD are presented followed by a review of the evidence on disorders that are comorbid with ASPD. Finally, a hypothesis is presented for orienting future research on the aetiology of ASPD and the development of effective programmes for reducing violence among persons with ASPD.     

An empirical study of object relations and defensive operations in antisocial personality disorder

This study assessed the object relations, defensive operations, and level of psychopathy and narcissism in a group of antisocial personality disordered offenders. The Rorschach protocols of 33 subjects who met the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R], American Psychiatric Association, 1987) criteria for antisocial personality disorder were analyzed utilizing Kwawer's (1980) criteria for borderline object relations categories (borderline phenomena), the Lerner and Lerner (1980) Defense Scale, and a number of experimental criteria including Cooper and Arnow's (1986) defense criteria. Level of narcissism was assessed utilizing Exner's (1973) Self-Focus Sentence Completion Test. Hare's Psychopathy Checklist was used as an independent variable to determine a subject's level of psychopathy. Those subjects scoring 30 or more on the psychopathy checklist were compared to subjects scoring less than 30. The level of narcissism or proportion of defenses did not differ significantly between the severe psychopaths (greater than or equal to 30) and the moderate psychopaths (less than 30). The severe psychopaths produced a significantly greater number of borderline object relations. I conclude that antisocial individuals tend to be highly egocentric, and that narcissism is one component of psychopathy. Severe psychopaths, as a group, tend to be more borderline in their functioning than those exhibiting moderate levels of psychopathic disturbance. I also conclude that individuals who are incarcerated for felony offenses and also meet the DSM-III-R criteria for antisocial personality disorder exhibit degrees of borderline personality organization.     

An Empirical Study of Object Relations and Defensive Operations in Antisocial Personality Disorder

This study assessed the object relations, defensive operations, and level of psychopathy and narcissism in a group of antisocial personality disordered offenders. The Rorschach protocols of 33 subjects who met the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-111-R], American Psychiatric Association, 1987) criteria for antisocial personality disorder were analyzed utilizing Kwawer's (1980) criteria for borderline object relations categories (borderline phenomena), the Lerner and Lerner (1980) Defense Scale, and a number of experimental criteria including Cooper and Arnow's (1986) defense criteria. Level of narcissism was assessed utilizing Exner's (1973) Self-Focus Sentence Completion Test. Hare's Psychopathy Checklist was used as an independent variable to determine a subject's level of psychopathy. Those subjects scoring 30 or more on the psychopathy checklist were compared to subjects scoring less than 30. The level of narcissism or proportion of defenses did not differ significantly between the severe psychopaths (230) and the moderate psychopaths (< 30). The severe psychopaths produced a significantly greater number of borderline object relations. I conclude that antisocial individuals tend to be highly egocentric, and that narcissism is one component of psychopathy. Severe psychopaths, as a group, tend to be more borderline in their functioning than those exhibiting moderate levels of psychopathic disturbance. I also conclude that individuals who are incarcerated for felony offenses and also meet the DSM-111-R criteria for antisocial personality disorder exhibit degrees of borderline personality organization.     

Histrionic personality disorder and antisocial personality disorder: sex-differentiated manifestations of psychopathy?

Little is known about the etiology of histrionic personality disorder (HPD) or its relation to other personality disorders. In this study, we examined whether HPD is etiologically related to psychopathy and more specifically whether HPD and antisocial personality disorder (ASPD) are sex-typed alternative manifestations of psychopathy. In addition, based on Newman's (1987) response modulation hypothesis of psychopathy, we examined the associations between psychopathic, HPD, and ASPD features and performance on laboratory measures of passive avoidance errors and interference effects. Seventy-five live theater actors completed self-report questionnaires and two laboratory measures of response modulation, and peers completed questionnaires concerning the participants' personality disorder features. The results provided weak and inconsistent support for the hypotheses that HPD is a female-typed variant of psychopathy and that ASPD is a male-typed variant of psychopathy. Contrary to previous findings, scores on response modulation tasks were not significantly related to psychopathy, or to either HPD or ASPD. The limitations of this study and possibilities for future research in this area are outlined.     

Substance-related disorders among juvenile offenders: what role do psychopathic traits play?

Substance use disorders are associated with psychopathy, a personality disorder that is heterogeneous in both adults and youth; secondary variants of psychopathy with comorbid psychopathology and primary variants without comorbidity show distinct correlates and outcomes. In adult criminal populations, secondary variants report greater substance abuse compared with primary variants. The primary aim of this study is to replicate and extend these findings to a juvenile offender population. Compared with primary variants of juvenile psychopathy, secondary variants (a) reported significantly more frequent substance use--particularly alcohol--within the 6 months prior to incarceration (d = .43), (b) were almost twice as likely to abuse substances while incarcerated, and (c) were more likely to be diagnosed with a current Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV; American Psychiatric Association, 2000) substance use disorder. Practical implications for working with justice-involved youth are discussed.     

Psychopathy and APD in Non-forensic Patients: Improved Predictions or Disparities in Cut Scores?

Psychopathy has traditionally been viewed as a distinct syndrome that is superior to Antisocial Personality Disorder (APD) for the prediction of violent and aggressive behavior. However, direct comparisons of psychopathy and APD are infrequent and mostly occur in correctional populations. Moreover, any observed differences could simply reflect a disparity in cut scores. The constellation of Psychopathy Checklists (PCL-R, PCL:SV, and PCL:YV) set the minimum cut score at 75% (e.g., ≥30 of 40 for the PCL-R), which is far more stringent than what is required for the DSM-IV APD adult criteria (i.e., ≥ 3 of 7 or 42.9%). For use in a non-forensic setting, we re-examined the MacArthur Risk Assessment data set to evaluate the usefulness of the PCL:SV and APD for short-term predictions of violent and aggressive acts. Using the ≥75% cut score to predict violence produced low sensitivities for both the psychopathy (.18) and APD adult criteria (.14) but very high specificities (.94). Reducing the cut score to approximately 40% greatly improved sensitivity rates (.62 for psychopathy and .85 for Adult APD criteria) at the expense of specificity (.59 and .40 respectively). In making multiple comparisons, psychopathy did not appear superior to APD adult criteria in predicting violent or other aggressive behavior. Instead, both constructs had limited predictive power with patients in a non-forensic setting. On an item level, specific indicators of violent behavior were explored.     

The Multidimensional Nature of Psychopathy: Five Recommendations for Research

The seven articles in this Special Section of the Journal of Psychopathology and Behavioral Assessment underscore the point that, at least in the psychopathy domain, parsimony is frequently an inaccurate scientific heuristic. These articles highlight the multidimensionality of youth psychopathy, suggesting that (a) the full constellation of psychopathy tends to outperform callous-unemotional traits alone in statistically predicting external criteria, (b) psychopathy subdimensions often interact statistically in predicting such criteria, and (c) psychopathy subdimensions often bear markedly different external correlates, including criminal offending, trait anxiety, and emotion processing. I offer five recommendations for future research on psychopathy and argue that that a full comprehension of this condition will require a better understanding of its subdimensions, and their interrelations, placement within the general personality domain, physiological correlates, and genetic and environmental underpinnings.     

Antisocial personality disorder and psychopathy: diagnostic dilemmas in classifying patterns of antisocial behavior in sentencing evaluations

Antisocial Personality Disorder (APD) and PCL-R psychopathy are critically examined regarding their application to sentencing determinations. PCL-R psychopathy is emerging in the literature as a more useful forensic diagnostic construct than APD, which appears flawed by multiple weaknesses. These include shifting diagnostic criteria, innumeracy problems, absence of symptom weighting, temporal instability, and the equivalence of some symptoms with substance abuse disorders. Additionally, APD overdiagnosis may result from inattention to issues of social context, trauma history, and symptom pervasiveness. Neither objective nor projective personality testing reliably differentiates APD. Finally, an APD diagnosis does not always indicate criminal, much less incorrigible criminal behavior. By contrast, PCL-R psychopathy results are strongly predictive of criminal behavior and violent recidivism for Caucasian males through mid-life residing in the community. Emerging research with the PCL-R regarding other important populations and contexts is promising but generalization is currently limited. © 1998 John Wiley & Sons, Ltd.     

Differential effects of psychopathy and antisocial personality disorder symptoms on cognitive and fear processing in female offenders

Psychopathy and antisocial personality disorder (APD) have long been considered important risk factors for criminal behavior and incarceration. However, little is known about the psychobiological underpinnings that give rise to the disinhibited behavior of female offenders. Using an instructed fear-conditioning paradigm and a sample of incarcerated female offenders, we manipulated attentional focus and cognitive load to characterize and differentiate between the dysfunctional cognitive and affective processes associated with these syndromes. We used fear-potentiated startle (FPS) and event-related potentials as measures of affective and cognitive processing, respectively. After controlling for APD symptoms, psychopathic women displayed greater FPS while attending directly to threat-relevant stimuli and displayed less FPS while performing a demanding task that directed attention to threat-irrelevant information. Conversely, controlling for psychopathy, women with high APD symptoms displayed less overall FPS, especially when instructed to focus on threat-relevant stimuli. However, as the demands on cognitive resources increased, they displayed greater FPS. For both psychopathy and APD, analysis of the event-related potentials qualified these findings and further specified the abnormal cognitive processes associated with these two syndromes. Overall, simultaneous analysis of psychopathy and APD revealed distinct patterns of cognitive processing and fear reactivity.     

The etiology of psychopathy: A neuropsychological perspective

While there is no universally accepted cause of psychopathy, there are basic biological patterns in brain dysfunction observed in individuals who display psychopathic tendencies. These individuals show significant impairment in specific regions of the brain, particularly the orbital frontal cortex (OFC). Such abnormalities exist in brain areas most involved in impulse control and behavior inhibition. There are also significant environmental factors that the majority of these individuals have in common. For example, a strong correlation exists between attachment disorder and anti-social personality disorder (ASPD). Finally, the differences between ASPD, psychopathy, and sociopathy are considered. While these terms are often used interchangeably, there are clear differences between these psychopathologies.     

The psychometric identification of psychopathy in mentally abnormal offenders

This study addressed the question of the degree of commonality, at a psychometric trait level, shared between two distinct concepts of psychopathy: a North American concept, defined in terms of chronic antisocial behaviour with early onset; and a European concept, defined in terms of personality deviation. Four groups of Broadmoor patients were identified who conformed to DSM-III criteria for the following diagnostic categories: Antisocial Personality Disorder (APD) (n = 12); Other Personality Disorders (OPD) (n = 9); Schizophrenic Disorders (SD) (n = 10); and a Mixed (M) group who met the criteria for both Schizophrenic Disorders and Antisocial Personality Disorder (n = 12). Thus subjects in both the APD and M groups, having a DSM-III diagnosis of Antisocial Personality Disorder, conformed to the North American concept of psychopathy. All diagnostic groups, together with a non-psychiatric control group of psychiatric nurses, were investigated using a composite battery of psychometric measures which tapped the two concepts of psychopathy. The only measure to discriminate successfully between patient groups with an APD diagnosis and other groups was Gough's (1969) Socialisation, which is itself a measure of the North American concept. Measures of personality deviation, including Blackburn's (1987) Belligerence and Withdrawal measures, failed to successfully discriminate DSM-III APD's from others. Thus the degree of trait commonality between the two concepts was found to be minimal. The study also addresses a fundamental question raised recently by both Hare and Harpur (1986) and Raine (1986) in criticism of a study by Howard, Bailey and Newman (1984): Are Broadmoor psychopaths “psychopathic” in the North American sense? Results of the study clearly indicate that they indeed are.     

Reliability and construct validity of the psychopathy checklist - revised for Latino, European American, and African American male inmates

The utility of the psychopathy construct in predicting laboratory deficits, criminal behavior, response to intervention, and recidivism has been well documented in European American populations. However, less is known about the manifestation and correlates of psychopathy in Latino and African American populations. The present study examined the reliability and construct validity of the Psychopathy Checklist - Revised (PCL-R; R. D. Hare, 2003) in 83 Latino inmates compared with matched samples of African Americans and European Americans. Results provide preliminary evidence that the PCL-R provides a reliable and valid measure of psychopathy in Latinos, with generally similar patterns emerging across external correlates; however, some ethnic group differences were noted for relationships between psychopathy indicators and some external correlates.     

Personality disorder and antisocial deviance: comments on the debate on the structure of the psychopathy checklist-revised

The recent debate on the structure of the Psychopathy Checklist-Revised (PCL-R: Hare, 1991; 2003) has been presented primarily as a statistical issue, but underlying it are longstanding conceptual issues about the relationship of personality concepts to deviant behavior and of psychopathy to criminality and personality disorder. I discuss these issues in this paper. The antisocial items of the PCL-R seem to reflect a propensity to commit crimes that has long been of interest to criminology. This disposition overlaps with, but differs conceptually from personality dispositions, but these surface dispositions do not provide a causal account of criminality. I present data that indicate that the core personality characteristics of psychopathy are more closely related to narcissistic and histrionic personality disorders than to antisocial personality disorder. Overemphasis on involvement in crime has obscured the nature of psychopathy as a disorder of personality characterised by interpersonally harmful behavior that need not necessarily take criminal form.     

An empirical investigation of psychopathy in a noninstitutionalized and noncriminal sample

This study examined the construct of psychopathy using the Psychopathy Checklist-Revised (PCL-R) in 54 participants from the general population. To obtain a sample of community participants with psychopathic characteristics, participants were recruited using advertisements for a "personality study" that incorporated the characteristics of psychopathy in a nonpejorative manner. The methodology successfully recruited community participants with moderately elevated PCL-R scores. Participants exhibited the personality features of psychopathy (Factor 1) to a greater extent than the behavioral features (Factor 2), which is consistent with the results obtained with the PCL-R normative samples. Roughly 40% of the sample reported no history of involvement with the criminal justice system, yet these participants exhibited moderately elevated PCL-R scores. Moreover, a sizeable portion of the noncriminal participants reported a substantial history of violent behavior. Comparisons of PCL-R scores between participants with and without a criminal history suggest that these two groups differ in ways unrelated to criminal justice system involvement.     

Hair pulling in African Americans--only your hairdresser knows for sure: an exploratory study

The authors examined whether African American hair care professionals saw individuals who met general criteria for trichotillomania, chronic hair pulling that results in significant hair loss. Thirty-eight African American hair care professionals and 1 Caucasian hair care professional were interviewed about their customers' hair-pulling behavior and condition of their hair. Sixteen African American hair care professionals saw 21 individuals who met general criteria for trichotillomania and reportedly perceived the behavior to be problematic. Four African American hair care professionals saw 6 individuals who met general criteria for trichotillomania but did not reportedly perceive the behavior to be problematic. Hair care professionals attributed most customers' hair-pulling behavior to bad nerves, stress, habit, and worry. Hair care professionals appeared adept at treating the consequences of chronic hair pulling but offered little assistance for the actual pulling behavior. Hair care professionals' contact with individuals who engage in chronic hair pulling raises interesting implications for prevention.     

The criminal and personality profile of patients with schizophrenia and comorbid psychopathic traits

Sixty-one male forensic patients who met the DSM-IV criteria for schizophrenia were categorised into high and low psychopathic trait groups using the Psychopathy Checklist: Screening Version. The groups were compared on their criminal history, symptom profile, personality style, risk scores and subsequent institutional violence. Patients with high scores on the PCL:SV had a greater number of previous convictions and were more likely to have a family history of criminality. The high psychopathy-scoring group had higher levels of Positive and Negative Syndrome Scale grandiose and hostile symptomatology, and higher scores on trait impulsivity and aggression. They also had a more coercive, less compliant interpersonal style than the low-psychopathy scoring group. The high-psychopathy scoring group were more likely to be involved in institutional aggression and had higher levels of risk for violence. Patients with schizophrenia and high levels of comorbid psychopathy have a distinctive interpersonal style that may contribute to their greater risk of disruptive institutional behaviour.
