Psychopathy and recidivism from mid-adolescence to young adulthood: Cumulating legal problems and limiting life opportunities.

This study examined the ability of psychopathy as indexed by the following 4 scales: Psychopathy Checklist: Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 1996/2003), Antisocial Process Screening Device (P. J. Frick & R. D. Hare, 2001), Hare Self-Report Psychopathy Scale-II (R. D. Hare, 1991), and Personality Assessment Inventory-Antisocial Scale (L. C. Morey, 1991, 2007) to prospectively predict antisocial outcomes including general and violent recidivism across a 3- to 4-year time span. Results indicated that psychopathy was predictive of both general and violent recidivism from mid-adolescence to young adulthood even after accounting for 14 variables theoretically linked to offending. These findings add to the recent research showing stability in the psychopathy traits across time by also demonstrating that psychopathy in adolescents also has a real-world effect, including a cost to society with higher rates of offending in the community and a cost to youth with cumulating legal records that are likely to narrow their potential for prosocial growth in the community.

Alcohol and drug abuse-dependence disorders in psychopathic and nonpsychopathic criminal offenders.

Co-occurrence of psychopathy (assessed with the Revised Psychopathy Checklist [R. D. Hare, 1985]) and lifetime Diagnostic and Statistical Manual of Mental Disorders (DSM-III) alcohol and drug disorders (assessed with the Diagnostic Interview Schedule; National Institute of Mental Health) was examined in a sample of 360 male inmates. Consistent with previous research that used diagnoses of antisocial personality disorder, psychopaths were more likely than nonpsychopaths to have lifetime diagnoses of alcoholism, any drug disorder, and multiple drug disorder. The relation between substance abuse and the 2 factors of the Revised Psychopathy Checklist was also examined. Substance abuse was significantly related to general social deviance (Factor 2) but was unrelated to core personality features of psychopathy (Factor 1). Two possible models of psychopathy (unitary syndrome vs dual-diathesis model) are presented that may account for the association between psychopathy and substance abuse.

The content validity of juvenile psychopathy: An empirical examination.

This study examined the content validity of a juvenile psychopathy measure, the Childhood Psychopathy Scale (CPS; D. R. Lynam, 1997), based on a downward translation of an adult instrument, the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). The CPS was compared with two other indices of juvenile psychopathy: (a) an index derived from expert ratings and (b) an empirical index based on correlations with adult psychopathy. The 100 items of the Common Language Q-Sort (CLQ; A. Caspi et al., 1992) provided a common metric for the comparison. Psychopathy and personality were assessed at age 13 years with the mother-reported CPS and the CLQ. Psychopathy was assessed at age 24 years with the interviewer-rated Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Data from over 250 participants of the middle sample of the Pittsburgh Youth Study were used to examine these relations. Item content analyses demonstrated considerable overlap among the three indices, indicating that the downward translation utilizes criteria similar to those of experts and the empirically-derived measure. In addition, these indices, even after removing overlapping items, demonstrated considerable convergence, also supporting the content validity of the downward translation. These results suggest that the downward translation method is adequate for understanding the juvenile psychopathy construct. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychopathy and Suicidality in Female Offenders: Mediating Influences of Personality and Abuse.

The influence of personality and childhood abuse on suicidal behaviors and psychopathy was examined among female prisoners. Scores on the affective/interpersonal component (Factor 1; F1) and the antisocial deviance (Factor 2; F2) component of psychopathy were obtained from the Psychopathy Checklist-Revised (R. D. Hare, 1991). Suicide attempt and childhood physical and sexual abuse history were coded from interviews and prison files, and personality was assessed using the Multidimensional Personality Questionnaire (A. Tellegen, in press). Suicide attempts were positively associated with F2 and negatively associated with F1, and each factor accounted for unique variance in suicidality. Path analyses demonstrated that personality mediated the effects of physical abuse on F2, but sexual abuse accounted for unique variance in both suicide attempts and F2. Abuse and personality accounted for minimal variance in F1. These results are discussed in relation to the identification of individuals at risk for both self- and other-harm behaviors.

Refining the construct of psychopathy: Towards a hierarchical model.

Psychopathy is characterized by diverse indicators. Clinical accounts have emphasized 3 distinct facets: interpersonal, affective, and behavioral. Research using the Psychopathy Checklist–Revised (PCL–R), however, has emphasized a 2-factor model. A review of the literature on the PCL–R and related measures of psychopathy, together with confirmatory factor analysis of PCL–R data from North American participants, indicates that the 2-factor model cannot be sustained. A 3-factor hierarchical model was developed in which a coherent superordinate factor, Psychopathy, is underpinned by 3 factors: Arrogant and Deceitful Interpersonal Style, Deficient Affective Experience, and Impulsive and Irresponsible Behavioral Style. The model was cross-validated on North American and Scottish PCL–R data, Psychopathy Screening Version data, and data derived from the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) antisocial personality disorder field trial.

Use of the Personality Assessment Inventory to assess psychopathy in offender populations.

The authors investigated the validity of the Antisocial Features (ANT) scale of the Personality Assessment Inventory (PAI; L. C. Morey, 1991) with respect to assessments of psychopathy in 2 offender samples. Study 1 included 46 forensic psychiatric inpatients who were administered the Screening Version of the Hare Psychopathy Checklist (PCL:SV; S. D. Hart, D. N. Cox, and R. D. Hare, 1995). In Study 2, 55 sex offenders were administered the Hare Psychopathy Checklist—Revised (PCL—R; R. D. Hare, 1991). ANT scores correlated highly with the PCL:SV total score (r?=?.54) and moderately with the PCL—R total score (r?=?.40). ANT tapped primarily behavioral symptoms of psychopathy rather than interpersonal and affective symptoms. Also, ANT had low to moderate diagnostic efficiency regarding diagnoses of psychopathy, suggesting that it may be better used as a dimensional rather than categorical measure of this construct.

Psychopathy, IQ, and Violence in European American and African American County Jail Inmates.

The accuracy of the prediction of criminal violence may be improved by combining psychopathy with other variables that have been found to predict violence. Research has suggested that assessing intelligence (i.e., IQ) as well as psychopathy improves the accuracy of violence prediction. In the present study, the authors tested this hypothesis by using a contemporary measure of psychopathy, the Psychopathy Checklist-Revised (R. D. Hare, 2003), in a sample of 326 European American and 348 African American male offenders. The postdictive power of psychopathy was evident for both ethnic groups and robust across most changes in the operationalization of violence and the analysis conducted, whereas the postdictive power of IQ was not. No Psychopathy x IQ interactions were identified. Implications of these results for violence prediction are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Understanding psychopathy through an evaluation of interpersonal behavior: Testing the factor structure of the interpersonal measure of psychopathy in a large sample of jail detainees.

Interpersonal characteristics are core features of the psychopathy construct which have a unique pattern of correlations with a variety of external correlates. To improve the assessment of interpersonal traits, the current study evaluated the internal structure of the Interpersonal Measure of Psychopathy (IM–P) through exploratory and confirmatory factor analyses (CFA) in a large sample of jail inmates. A 17-item, 3-factor (Dominance, Grandiosity, and Boundary Violations) structure evidenced good fit in European American inmates. A second CFA demonstrated good fit for this structure in a sample of African American inmates. Moreover, a multigroup CFA indicated structural invariance between European and African American inmates. External validity was tested and demonstrated through positive correlations between IM–P factor scores and Psychopathy Checklist—Revised total and facet scores (R. D. Hare, 2003) and antisocial personality disorder symptoms and diagnoses. Modest correlations between Grandiosity scores and scores on the Shipley Institute of Living Scale—Revised (R. A. Zachary, 1994) were also observed. Finally, a step-down hierarchical regression was conducted to test for racial bias of the IM–P factor scores in relation to external correlates. Little evidence was found for slope bias, but there was evidence of intercept bias for some analyses. Implications and advantages of assessing psychopathy through a comprehensive evaluation of interpersonal traits are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

One measure does not a construct make: Directions toward reinvigorating psychopathy research—reply to Hare and Neumann (2010).

In our article by J. L. Skeem & D. J. Cooke, (2010), we outlined the dangers inherent in conflating the Psychopathy Checklist—Revised (PCL–R; R. Hare, 1991) with psychopathy itself. In their response, R. Hare and C. Neumann (2010) seemed to agree with key points that the PCL–R should not be confused with psychopathy and that criminal behavior is not central to psychopathy; at the same time, they said we provided no clear directions for theory or research. In this rejoinder, we clarify our argument that progress in understanding the unobservable construct of psychopathy hinges upon setting aside procrustean dependence on a monofocal PCL–R lens to test (a) actual theories of psychopathy against articulated validation hierarchies and (b) the relation between psychopathy and crime. In specifying these conceptual and applied directions, we hope to promote constructive dialogue, further insights, and a new generation of research that better distinguishes between personality deviation and social deviance.

Psychopathy and alexithymia in female offenders.

Determined the comorbidity of psychopathy and alexithymia in 37 female inmates of a medium-security prison. The authors also investigated the association between psychopathy and alexithymia with the use of affective language in response to questions about an emotional event, and with their propensity for violence. The extent of psychopathy and alexithymia were assessed with the Hare Psychopathy Checklist—Revised (PCL-R) and the Toronto Alexithymia Scale (TAS), respectively. Using standard cutoff scores, 30% were identified as psychopaths, and 32% as alexithymics. Three Ss were both psychopaths and alexithymics. The correlation between PCL-R and TAS total scores was not significant, but the socially deviant impulsive factor of the PCL-R significantly correlated with the TAS items that reflect inability to discriminate feelings and bodily sensations. Alexithymia, but not psychopathy, was negatively related to measures of affective speech content. Both psychopathy and alexithymia were associated with a history of violence. In spite of several manifest similarities, psychopathy and alexithymia appear to be different clinical constructs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Is criminal behavior a central component of psychopathy? Conceptual directions for resolving the debate.

The development of the Psychopathy Checklist—Revised (PCL–R; R. D. Hare, 2003) has fueled intense clinical interest in the construct of psychopathy. Unfortunately, a side effect of this interest has been conceptual confusion and, in particular, the conflating of measures with constructs. Indeed, the field is in danger of equating the PCL–R with the theoretical construct of psychopathy. A key point in the debate is whether criminal behavior is a central component, or mere downstream correlate, of psychopathy. In this article, the authors present conceptual directions for resolving this debate. First, factor analysis of PCL–R items in a theoretical vacuum cannot reveal the essence of psychopathy. Second, a myth about the PCL–R and its relation to violence must be examined to avoid the view that psychopathy is merely a violent variant of antisocial personality disorder. Third, a formal, iterative process between theory development and empirical validation must be adopted. Fundamentally, constructs and measures must be recognized as separate entities, and neither reified. Applying such principles to the current state of the field, the authors believe the evidence favors viewing criminal behavior as a correlate, not a component, of psychopathy.

A new method for assessing the interpersonal behavior of psychopathic individuals: Preliminary validation studies.

Two studies examined whether increased attention to interpersonal behaviors would improve assessments of the personality core underlying psychopathy. After item analysis, 21 items measuring interpersonal interactions and nonverbal behaviors associated with psychopathy were retained as the Interpersonal Measure of Psychopathy (IM-P). Federal prison inmates (Study 1, N?=?98) and undergraduates (Study 2, N?=?92) were rated on occurrence of these behaviors during an interview conducted to complete either Hare's Psychopathy Checklist—Revised (PCL-R) or Psychopathy Checklist: Screening Version (PCL: SV). In both studies, IM-P scores correlated more highly with PCL Factor 1 than with PCL Factor 2 scores. Regression analyses indicated that, after controlling for demographic variables and PCL factor scores, IM-P scores predicted interviewer emotional responses and participants' adult fighting (Study 1) and ratings of participants' interpersonal dominance (Study 2). Thus, measurement of interpersonal behavior appears to permit improved prediction of several criteria linked to the personality core of psychopathy.

Child psychopathy and protective factors: IQ and motivation to change.

Psychopathy in children and adolescents has received increased attention over the past decade. Researchers have been particularly interested in identifying who tomorrow's chronic and serious offenders might be. In addition, researchers have been increasingly interested in determining the etiology of the disorder so as to inform treatment programs. Despite this interest, few studies to date have investigated the protective factors for psychopathy in youth. The current study investigated 140 adolescent boys and girls and the potential protective mechanisms of intelligence and motivation to change. Findings indicated that motivation to change served as a protective factor for general and violent offending at varying levels of psychopathy. Motivation to change also served as a compensatory factor for psychopathy when examining high rates of violent offending. These findings suggest that the cognitive factor of motivation to change may very well be critical in examining developmental pathways to offending in youth and a key consideration for those youth scoring high on psychopathy scales and considering violence as a means of gain.

Longitudinal evidence that psychopathy scores in early adolescence predict adult psychopathy.

This study examined the relation between psychopathy assessed at age 13 by using the mother-reported Childhood Psychopathy Scale (D. R. Lynam, 1997) and psychopathy assessed at age 24 by using the interviewer-rated Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Data from over 250 participants of the middle sample of the Pittsburgh Youth Study were used to examine this relation; approximately 9% of the sample met criteria for a possible PCL:SV diagnosis. Despite the long time lag, different sources, and different methods, psychopathy from early adolescence into young adulthood was moderately stable (r=.31). The relation was present for the PCL:SV total and facet scores, was not moderated by initial risk status or initial psychopathy level, and held even after controlling for other age 13 variables. Diagnostic stability was somewhat lower. Both specificity and negative predictive power were good, and sensitivity was adequate, but positive predictive power was poor. This constitutes the first demonstration of the relative stability of psychopathy from adolescence into adulthood and provides evidence for the incremental utility of the adolescent psychopathy construct. Implications and future directions are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Therapeutic responses of psychopathic sexual offenders: Treatment attrition, therapeutic change, and long-term recidivism.

The authors examined the therapeutic responses of psychopathic sex offenders (≥25 Psychopathy Checklist—Revised; PCL–R) in terms of treatment dropout and therapeutic change, as well as sexual and violent recidivism over a 10-year follow-up among 156 federally incarcerated sex offenders treated in a high-intensity inpatient sex offender program. Psychopathy and sex offender risk/treatment change were assessed using the PCL–R and the Violence Risk Scale—Sexual Offender version (VRS–SO), respectively. Although psychopathic participants were more likely than their nonpsychopathic counterparts (     

Psychopathy, antisocial personality, and suicide risk.

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.

Validating the factor structure of the Self-Report Psychopathy Scale in a community sample.

Currently, there is no standard self-report measure of psychopathy in community-dwelling samples that parallels the most commonly used measure of psychopathy in forensic and clinical samples, the Psychopathy Checklist. A promising instrument is the Self-Report Psychopathy scale (SRP), which was derived from the original version the Psychopathy Checklist. The most recent version of the SRP (SRP-III; D. L. Paulhus, C. S. Neumann, & R. D. Hare, in press) has shown good convergent and discriminate validity and a factor structure similar to the current version of the Psychopathy Checklist (PCL-R; R. D. Hare, 1991, 2003). The analyses in the current study further investigated the viability of the SRP-III as a PCL-R-analogous measure of psychopathy in nonforensic and nonclinical samples by extending the validation process to a community sample. Using confirmatory factor analyses and logistic regressions, the results revealed that a four-factor oblique model for the SRP-III was most tenable, congruent with the PCL-R factor structure of psychopathy and previous research in which the SRP-III was administered to a student sample.

Associations among early abuse, dissociation, and psychopathy in an offender sample.

Theorists have postulated that some variants of psychopathy result from childhood abuse and neglect. Dissociative symptoms are also thought to arise from abuse. To date, the conjoint associations among abuse, dissociation, and psychopathy have not been examined systematically. Some have hypothesized that abuse relates primarily to the affective symptoms of psychopathy, with dissociative experiences mediating this relationship. Others have suggested that abuse more directly affects the impulsive lifestyle features of psychopathy. The authors used structural equation modeling to examine these hypotheses in a sample of 615 male offenders who had completed a retrospective self-report measure of childhood abuse, the Dissociative Experiences Scale, and R. D. Hare's (2003) Psychopathy Checklist-Revised. Abuse exerted no direct or indirect effect on the core interpersonal and affective features of psychopathy but was directly related to the facet of psychopathy associated with an impulsive and irresponsible lifestyle. Implications for psychopathy subtypes are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Emotion at the expense of cognition: Psychopathic individuals outperform controls on an operant response task.

The impact of emotional stimuli on a simple motor response task in individuals with psychopathy and comparison individuals was investigated. Psychopathy was assessed using the Psychopathy Checklist Revised (Hare, 1991). Participants were presented with the Emotional Interrupt Task, in which they responded with left and right button presses to shapes that were temporally bracketed by positive, negative, and neutral visual images taken from the International Affective Picture System. The comparison group showed increased response latencies if the shape was temporally bracketed by either a positive or negative emotional stimulus relative to a neutral stimulus. Individuals with psychopathy did not show this modulation of reaction time for either positive or negative emotional stimuli. Results are discussed with reference to current models regarding the modulation of attention by emotion and the emotional impairment seen in individuals with psychopathy.
