Proposed Specifiers for Conduct Disorder (PSCD): Further validation of the parent-report version in a nationally representative U.S. sample of 10- to 17-year-olds.

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.

Proposed Specifiers for Conduct Disorder (PSCD) scale: A Latent Profile Analysis with At-Risk Adolescents.

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).

Validating latent profiles of the Psychopathy Checklist-Revised with a large sample of incarcerated men.

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.

Proposed Specifiers for Conduct Disorder (PSCD): Factor structure and psychometric properties in a residential school facility.

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 ( = 409; age = 16-19; 80.

The Proposed Specifiers for Conduct Disorder (PSCD) Scale: Factor Structure and Validation of the Self-Report Version in a Forensic Sample of Belgian Youth.

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 (5th ed.

Psychopathic Expression From Early to Late Adulthood: An Item Response Theory Analysis of the Hare Psychopathy Checklist-Revised.

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 ( = 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.

Factor Structure and Construct Validity of the Proposed Specifiers for Conduct Disorder (PSCD) Scale in Chinese Adolescents.

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 ( = 1,683; mean age = 13.60, = 1.

[Psychopathy in female inmates in Chile].

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.

Decompression sickness: a guide for emergency nurses.

Decompression sickness (DCS) is commonly associated with diving or occupational exposure to compressed air, and is a life-threatening condition if left untreated. This article provides an overview of the pathophysiology and types of DCS. It also explains the principles of care for people presenting to the emergency department with DCS that emergency nurses must be familiar with, including the recognition of its signs and symptoms and the initial management required.

A Latent Profile Analysis of Violent Offenders Based on PCL-R Factor Scores: Criminogenic Needs and Recidivism Risk.

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.

[Psychopathy among inmate population in Argentina and Chile: Characterization and transnational norms].

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.

Hervey Cleckley (1903-1984): Contributions to the study of psychopathy.

Hervey Cleckley (1903-1984) was probably among the most influential psychiatrists of the 20th century, but the history of his intellectual contributions to psychopathy is not especially well known. Not all of Cleckley's writings have stood the test of time, but others seem prescient, arguably anticipating current debates regarding such contentious issues as successful psychopathy and the treatability of psychopathy. Although Cleckley's seminal writings on psychopathy are familiar to many contemporary scholars, Cleckley's role as an expert witness and his writings on other topics, such as dissociative identity disorder, may be less familiar to many readers.

A comprehensive examination of the psychometric properties of the Hare Psychopathy Checklist-Revised in a Canadian multisite sample of indigenous and non-indigenous offenders.

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.

A taxometric investigation of psychopathy in women.

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.

Examining the interrater reliability of the Hare Psychopathy Checklist-Revised across a large sample of trained raters.

The goal of the current study was to assess the interrater reliability of the Psychopathy Checklist-Revised (PCL-R) among a large sample of trained raters (N = 280). All raters completed PCL-R training at some point between 1989 and 2012 and subsequently provided complete coding for the same 6 practice cases. Overall, 3 major conclusions can be drawn from the results: (a) reliability of individual PCL-R items largely fell below any appropriate standards while the estimates for Total PCL-R scores and factor scores were good (but not excellent); (b) the cases representing individuals with high psychopathy scores showed better reliability than did the cases of individuals in the moderate to low PCL-R score range; and (c) there was a high degree of variability among raters; however, rater specific differences had no consistent effect on scoring the PCL-R.

Using latent variable- and person-centered approaches to examine the role of psychopathic traits in sex offenders.

The current study employed both latent variable- and person-centered approaches to examine psychopathic traits in a large sample of sex offenders (N = 958). The offenders, who had committed a range of sexual crimes, had been assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four-factor model of psychopathy (Hare, 2003; Neumann, Hare, & Newman, 2007) provided good representation of the dimensional nature of psychopathic traits across the sample of offenders, and that the PCL-R factors significantly predicted sexual crimes.

The construct of psychopathy in a Chilean prison population.

Objective: To test the four-factor model of the Hare Psychopathy Checklist - Revised (PCL-R) empirical construct of psychopathy in a Chilean prison population by using instruments that supply different types of data.

Methods: Two hundred and nine male inmates of the Prison of Los Andes, Chile, were evaluated. Confirmatory factor analysis was carried out with the PCL-R and the Self-Report of Psychopathy - III - Short Form (SRP-III-SF).

Variants of psychopathy in adult male offenders: A latent profile analysis.

As measured with the Psychopathy Checklist-Revised (PCL-R), psychopathy is a dimensional construct underpinned by 4 correlated factors: Interpersonal, Affective, Lifestyle, and Antisocial. Theorists and clinicians (e.g.

[Reliability of the Chilean version of the Hare PCL-R and convergent validity with other assessment tools for psychopathy].

Introduction: Evaluation of mental health in forensic field is relevant in order to plan interventions and diminish institutional risks. The procedure includes the evaluation of psychopathic traits, which should be assessed by reliable and valid instruments.

Objectives: To evaluate the internal congruence of the Chilean version of the PCL-R, and the convergent validity with the PCL: SV, the SRP-III-SF and the IM-P.

Antisociality and the Construct of Psychopathy: Data From Across the Globe.

Previous theory and research on the structural, longitudinal, and genetic nature of psychopathy have provided strong conceptual and empirical evidence that overt antisociality is a component of the psychopathy construct (Hare & Neumann, 2008, 2010; Lynam & Miller, 2012). However, determination of the strength of the association between antisociality and other psychopathic features has not been explored systematically. The current article draws on previously published large North American studies, as well as data from across the globe, to estimate the strength and pattern of the associations between overt antisociality and other psychopathic domains in a diverse set of samples.

Corporate psychopathy and the full-range leadership model.

The B-Scan 360 is a relatively new, purpose-built measure of corporate psychopathy that addresses many of the issues inherent in studying psychopathy in organizations. The primary goal of the present study was to measure the relationship between employees' perception of psychopathic features in their supervisor and their rating of their supervisor on the Full-Range Model of Leadership. The second goal of the study was to test the B-Scan 360's factor structure and test its interrater reliability in an organizational sample.

Psychopathic traits in females and males across the globe.

The current study examined the prevalence and structure of psychopathic traits in females and males using a very large world sample (N = 33,016, females = 19,183). Psychopathic traits were assessed with the Self-Report Psychopathy (SRP) scale, and structural equation modeling (SEM) was used to test the four-factor model of psychopathy (interpersonal, affective, lifestyle, antisocial) both in the total sample and in the separate samples of females and males. Multi-sample confirmatory factor analysis was used to test for invariance of model parameters across sex as well as across females from different world regions.
