The Proposed Specifiers for Conduct Disorder (PSCD; Salekin & Hare, 2016) is a new self-report and informant measure designed to assess psychopathic characteristic domains along with symptoms of conduct disorder in youth. Previous factor analytic studies on the PSCD have found that the items are accounted for by a four-factor model reflecting grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder (CD) symptoms. The present study examined the factor structure, psychometric properties, and criterion-related validity of the parent-report version of the PSCD (PSCD-P) in a nationally representative U.S. sample of children and adolescents (N = 1,091, Mage = 13.39, SD = 2.20, range age = 10-17; 50.0% boys, 76% White). Confirmatory factor analyses for the full (24-item) and a shortened (13-item) PSCD-P revealed good internal reliability estimates and support for the four-factor model (grandiose-manipulative, callous-unemotional, daring-impulsive, CD). Results also provided evidence for (a) measurement invariance of the PSCD-P items across sex, race/ethnicity, and age of the child; (b) convergent validity with CD/oppositional defiant disorder symptoms and discriminant validity with a measure of neuroticism; and (c) criterion-related validity with respect to prosociality, peer and family functioning, reactive and proactive aggression, delinquency, academic performance, and substance use. The prevalence for psychopathic personality propensity was found to be 2%. We discuss clinical and research implications regarding the use of the parent-report version of the PSCD for school-aged children. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

This is the first study to test the psychometric properties of the self-report version of the Proposed Specifiers for Conduct Disorder (PSCD) in detained youth. The PSCD is a measure of the broad psychopathy construct, with grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder (CD) components. Participants (227 males) completed the PSCD along with other measures, including a diagnostic interview to assess Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) CD. Results support the PSCD's proposed hierarchical four-factor structure. Correlations with an alternate measure of psychopathy and symptoms of CD support the convergent validity of PSCD scores. PSCD scores showed positive associations with criterion variables of emotional and regulatory functioning, aggression, substance use, and school problems. Finally, PSCD scores were unrelated to anxiety and depression, supporting the PSCD's discriminant validity. Findings indicate that the PSCD is a promising measure for assessing psychopathic traits in detained male adolescents, though its incremental validity is in need of further scrutiny.

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin in Pers Disord: Theory Res Treat 7:180–191, 2016) scale was designed to assess interrelated psychopathic trait domains in conjunction with symptoms of Conduct Disorder (CD) in children and adolescents (i.e., grandiose-manipulative, callous-unemotional, daring-impulsive). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985–992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9

There is a long tradition of theory and research on putative variants of psychopathic and other antisocial clinical presentations. However, using different samples, psychopathy measures, terminologies, and analytic methods makes interpretation of the findings difficult. Emerging research suggests that the validated four-factor model of the Psychopathy Checklist-Revised (PCL-R) provides a consistent and empirically robust framework for identifying psychopathic variants and antisocial subtypes (Hare et al., 2018; Neumann et al., 2016). The current study employed latent profile analysis (LPA) of the full range of PCL-R scores in a large sample of incarcerated men (N = 2,570) to replicate and extend recent LPA research on PCL-R-based latent classes. Consistent with previous research, a four-class solution emerged as optimal, with the following antisocial subtypes: Prototypic Psychopathic (C1), Callous-Conning (C2), Externalizing (C3), and General Offender (C4). We validated the subtypes by examining their differential associations with theoretically meaningful external correlates: Child conduct disorder symptoms; adult nonviolent and violent offenses; Self-Report Psychopathy; Psychopathic Personality Inventory; Symptom Checklist-90 Revised; and behavioral activation system and behavioral inhibition system scores. The discussion focused on conceptions of the PCL-R-based subgroups and their potential application to risk assessment and treatment/management programs.

The Proposed Specifiers for Conduct Disorder scale (PSCD; Salekin & Hare, 2016) is a new scale for the assessment of psychopathic characteristic domains in children and adolescents. The four domains are Grandiose-manipulative (GM), Callous-unemotional (CU), Daring-impulsive (DI), and Conduct Disorder (CD). We examined the properties of the self-report version of the PSCD in a large sample of adolescents (n = 409; age = 16-19; 80.6% male) in a military-style residential facility. Factor analytic results supported a four-factor model consistent with other PSCD research (e.g., López-Romero et al., 2019; Luo et al., 2021). Structural equation model (SEM) indicated a superordinate PSCD factor accounted for significant variance in self-reported delinquency history. The PSCD had good internal consistency and strong convergent and discriminant validity with measures of externalizing and internalizing disorders. The present study provides encouraging data that the PSCD may provide a sound measure of psychopathic propensities in youth. However, additional data are needed to test the stability of the PSCD.

Several investigators have assessed the Psychopathy Checklist-Revised (PCL-R) for invariance across offender ethnicities and in correctional and forensic-psychiatric contexts. Yet we do not know whether, or to what extent, item properties among male offenders vary throughout adulthood. With a combined sample of PCL-R data on offenders from Canada and the United States (N = 4,820), we measured item properties for offenders in age groups of Early (18-30 years old), Middle (31-49 years old), and Late (50+ years old) adulthood. Nine items showed differential item functioning across age group comparisons. Among the Early group, the PCL-R Interpersonal and Affective traits were most informative for measuring the latent trait of psychopathy. Among the Late group, the PCL-R Lifestyle and Antisocial items were most informative for the latent trait. These differences in item information illustrate how psychopathy manifests in male offenders throughout adulthood.

Purpose: There is a dearth of empirical data on the contributions of personality, psychopathology, and psychopathy to terrorism and its actors. Because of a fortuitous set of circumstances, we had access to a sample of men convicted of crimes against humanity (CAH) committed during the Pinochet regime, each rated by expert clinicians on the Psychopathy Checklist-Revised (PCL-R). We also had PCL-R ratings for samples of general offenders and community participants. Methods: We determined the psychometric properties of the PCL-R for these samples, performed structural equation modeling (SEM) to investigate the factor structure of the PCL-R, and conducted a latent profile analysis (LPA) of the obtained factors to identify classes or subtypes within the samples. Results: The PCL-R's psychometric properties and factor structure were in accord with findings from other countries and settings. The PCL-R total scores of the CAH and general offenders were virtually the same but much higher than those of the community sample. However, the CAH group had extraordinarily high scores on the Interpersonal/Affective facets yet relatively low scores on the Lifestyle/Antisocial facets. LPA identified the expected four latent classes, with most CAH men located within the Callous-Conning class. Conclusions: The results of this study provide unique information about the psychopathic propensities of a sample of state violators of human rights. Their pattern of PCL-R scores was consistent with an extreme disposition for self-serving, callous, and ruthless treatment of others, without guilt or remorse, and in the absence of a prior documented history of severe antisocial behavior.

It integrates findings from research in other settings or with other dark personalities. The chapter offers observations and hypotheses as to how we might apply these findings to psychopathy in business operations. It suggests recommendations and avenues for future research on corporate psychopathy. The chapter uses the term corporate psychopathy to refer to all aspects of psychopathy in the workplace. The Psychopathy Checklist-Revised is a 20-item clinical construct rating scale that uses a semi-structured interview, case history information, and specific scoring criteria to rate each item on a three-point scale (0, 1, 2) according to the extent to which the item applies to the individual. Much of the research on psychopathy has involved the use of variable-centered approaches, such as confirmatory factor analysis and structural equation modeling.

A group of 13 authors (GA) shared a statement of concern (SoC) warning against the use of the Hare Psychopathy Checklist-Revised (PCL-R; Hare. 1991, 2003) to assess risk for serious institutional violence in U.S. capital sentencing cases (DeMatteo et al.. 2020). Notably, the SoC was not confined to capital sentencing issues, but included institutional violence in general. Central to the arguments presented in the SoC was that the PCL-R has poor predictive validity for institutional violence and also inadequate field reliability. The GA also identified important issues about the fallibility and inappropriate use of any clinical/forensic assessments, questionable evaluator qualifications, and their effects on capital sentencing decisions. However, as a group of forensic academics, researchers, and clinicians. we are concerned that the PCL-R represents a psycholegal red herring, while the SoC did not sufficiently address critical legislative, systemic, and evaluator/rating issues that affect all forensic assessment tools. We contend that the SoC's literature review was selective and that some of the resultant opinions about uses and misuses of the PCL-R were potentially misleading. We focus our response on the evidence and conclusions proffered by the GA concerning the use of the PCL-R in capital and other cases. We provide new empirical findings regarding the PCL-R's predictive validity and field reliability to further demonstrate its relevance for institutional violence risk assessment and management. We further demon-strate why the argument that group data cannot be relevant for single-case assessments is erroneous. Recommendations to support the ethical and appropriate use of the PCL-R for risk assessment are provided.

DeMatteo et al. (2020b) published a Statement in this journal declaring that the Psychopathy Checklist-Revised (PCL-R) "cannot and should not [emphasis added]" (p. 134) be used in U.S. capital-sentencing cases to assess risk for serious institutional violence. Their stated concerns were the "imperfect interrater reliability" (p. 137), the "variability in their predictive validity" (p. 137), and the prejudicial effects of PCL-R ratings on the defendant. In a Cautionary Note, we (Olver et al., 2020) raised questions about the Statement's evaluation of the PCL-R's psychometric properties; presented new data, including a meta-analysis; and argued that the evidence did not support the Statement's declaration that the PCL-R cannot be used in high-stakes contexts. In their reply, titled "Death is Different," DeMatteo et al. (2020a) concurred with several points in our Cautionary Note, disputed others, asserted that we had misunderstood or mischaracterized their Statement, and dismissed our new data and comments as irrelevant to the Statement's purpose. This perspective on our commentary is inimical to balanced academic discourse. In this article, we contend that DeMatteo et al. (2020a) underestimated the reliability and predictive validity of PCL-R ratings, overestimated the centrality of the PCL-R in sentencing decisions, and underplayed the importance of other factors. Most of their arguments depended on sources other than capital cases, including mock trials, sexually violent predator hearings, and studies that included the prediction of general violence. We conclude that the rationale for the bold "cannot and should not" decree is open to debate and in need of research in real-life venues.

The Proposed Specifiers for Conduct Disorder (PSCD) Scale is a new measure to assess psychopathic traits and symptoms of conduct disorder (CD) in children and adolescents. The current study examined the psychometric properties of the self-report version of the PSCD in a sample of community adolescents in mainland China (N = 1,683; mean age = 13.60, SD = 1.14; 54.1% boys). The new instrument showed good internal consistency (alpha) for the 24-item total scale and good mean interitem correlations for each of the six-item subscales. Confirmatory factor analyses (CFAs) were conducted on all 24 items, and also a subset of 13 items that demonstrated strong item-level reliabilities. Using all 24 items, CFA results supported a four-factor bifactor model indicating the total score reflects a broad syndrome with four factors. The four factors included grandiose-manipulative traits (GM traits), callous-unemotional traits (CU traits), daring-impulsive traits (DI traits), and CD traits. The 13-item CFA results provided further support for a four-factor conceptualization of the PSCD and evidence of strong measurement invariance across gender. Finally, the PSCD exhibited the expected relations with other psychopathy measures, anxiety and depression, and aggression, supporting the PSCD scores convergent, discriminant, and criterion related validity. The findings provide preliminary evidence for the four-factor structure of the PSCD and support for the utility of the self-report PSCD for measuring psychopathic traits and CD in Chinese adolescents.

INTRODUCTION:although psychopathy is a clinical construct of great importance for both the clinical and forensic field, previous Latin American research has been focused mainly on males.OBJECTIVES:determine the prevalence of psychopathy and of antisocial personality disorder in imprisoned female population. To explore the distribution scores obtained with the PCL-R and to test its psychometric characteristics.METHOD:a randomized sample of 210 participants was obtained from the 570 women imprisoned in the female prison in Santiago, Chile, in June 2014. The participants were evaluated by two independent researchers with the Hare Psychopathy Checklist and the Interpersonal Measure of Psychopathy. The information was obtained from different sources and the interviews were all video-registered for its double check.RESULTS:Prevalence of psychopathy was 11,9% and antisocial personality disorder 43,8%. The results assert that the Psychopathy Checklist - Revised is reliable and valid to be used in women and provide the norms for the professionals working with inmate female population.

The Proposed Specifiers for Conduct Disorder (PSCD) scale (Salekin & Hare, 2016) was developed as a measure of the broader construct of psychopathy in childhood and adolescence. In addition to conduct disorder (CD) symptoms, the PSCD addresses the interpersonal (grandiose-manipulative), affective (callous-unemotional), and lifestyle (daring-impulsive) traits of psychopathic personality. The PSCD can be scored by parents and teachers. The present study is a preliminary test of the psychometric properties of the PSCD-Parent Version in a sample of 2,229 children aged 3 to 6 years. Confirmatory factor analyses supported both a 3- and 4-factor structure being invariant across gender groups. The validity of the PSCD was also supported by convergent-divergent associations with an alternative measure of psychopathic traits as well as by the expected relations with fearlessness, conduct problems, reactive and proactive aggression, attention-deficit hyperactivity disorder and oppositional defiant disorder symptoms, and social competence skills. Overall, the PSCD is a promising alternative measure for assessing early manifestation of the broader construct of psychopathy in children. Its use should facilitate discussion of the conceptualization, assessment, predictive value, and clinical usefulness of the psychopathic construct as it relates to CD at early developmental stages.

Clinicians and theorists have often proposed the two psychopathic subtypes of "primary" and "secondary" psychopathy, with recent research indicating some empirical support for both psychopathy subtypes, though the findings across studies are far from uniform. For the current study, latent profile analysis was used to investigate if homogeneous latent classes exist within a sample of 215 adult male violent offenders from Berlin, Germany. The age of the offenders at the time of the index offense ranged from 19 to 59 years. The results indicated a solution with four latent classes, which we refer to as prototypical psychopaths (LC1), callous-conning offenders (LC2), sociopathic or dyssocial offenders (LC3), and general offenders (LC4). Validation of the four subtypes involved examination of differences on recidivism risk; criminogenic needs; and general, violent, and sexual reoffending. The results also are discussed in terms of the issue of treatment amenability.

INTRODUCTION:In Latin America, there is evidence on the prevalence of psychopathy in prison population and on the validity and reliability of the specifc assessment instrument; but there has been no exploration on whether psychopaths have different characteristics in different countries nor has there been an integration of a transnational normative sample.OBJECTIVE:To test the universality of the construct comparing psychopaths of the Chilean and Argentinian sample and to formulate norms for the prison population with both samples pooled.METHOD:Samples of Argentinian prison inmate population (n = 153) and Chilean (n = 209) assessed with the PCL-R and HCR-20 were compared. An aggregated sample was made for descriptive purposes and in order to formulate the norms.RESULTS:Findings supported the non-differentiation hypothesis between Chilean and Argentinian psychopaths. Differences were found in the dynamic risk factors for violent recidivism that were attributed to the time spent in prison of the inmates. The percentiles for the PCL-R total and factors values in the aggregated sample was similar to the individual Chilean and Argentinian samples.

The taxonomic status of psychopathy is the topic of considerable research interest. The latent structure of psychopathy will latent structure will guide the determination of the best assessment approaches, maximize the reliability and validity, will help to establish optimal cutting scores that minimize decision errors and will also facilitate the selection of the best research designs to advance the study of the construct. In the present study, taxometric analyses were used for assessing taxonicity, and they were applied to Psychopathy Checklist-Revised (PCL-R) ratings of 1218 female offenders. Hare's four-factor solution to the PCL-R was used as the bases of the analyses. The results of the various analytical strategies obtained dimensional solutions and corroborated that for females, as well as for males, psychopathy as measured by the PCL-R, may best be conceptualized as distinct configurations of extreme scores on personality traits rather than as a distinct, nonarbitrary class. These results reaffirm the fact that cut-off scores of are arbitrary in nature.

The present study examined the psychometric properties of Hare Psychopathy Checklist-Revised (PCL-R; Hare, 2003) scores in a multisite sample of 1,163 federally incarcerated Canadian indigenous and non-indigenous offenders from the Prairie Region of the Correctional Service of Canada. The research occurred against the backdrop of the Ewert v. Canada (2015) matter, in which the PCL-R was originally impugned in Federal Court for use with indigenous persons (later overturned in Canada v. Ewert, 2016). Indigenous men scored higher than non-indigenous men on most components of the PCL-R and had higher rates of recidivism, irrespective of follow-up. Discrimination analyses, however, supported the predictive efficacy of PCL-R total, factor, and facet scores for violent and general recidivism across both ancestral groups, with most group differences in area under the curve (AUC) magnitudes being small and nonsignificant. Calibration analyses demonstrated that higher PCL-R scores were associated with higher rates of general and violent recidivism for both ancestral groups, although higher recidivism rates were observed and estimated for indigenous men at specific PCL-R score thresholds. Confirmatory factor analyses supported the 4-factor model of psychopathy and hence, structural invariance, of PCL-R scores across ancestral groups. Structural equation modeling affirmed the predictive efficacy of the 4-factor model for recidivism. We discuss these findings in terms of clinical applications of the PCL-R and the psychopathy construct in general, with male offenders of indigenous ancestry. (PsycINFO Database Record
