Psychopathic traits in the context of paid erotic services and sex exchange among college students.

Scholars have begun to explore college student engagement in erotic services (e.g., pornography, escort); however, few studies in the United States have examined the prevalence of erotic service involvement among college students and which personality traits are associated with such engagement. This study examined the relevance of gender and psychopathic traits, above the influence of substance use, for understanding erotic service involvement in men and women college students. A total of 1,250 undergraduate students (800 women) completed the Self-Report Psychopathy Scale-III and Erotic Activity Questionnaire. Men and women, respectively, endorsed low-moderate provision levels (12.25% and 11.00%) and moderate-high consumption levels (44.17% and 26.16%) of erotic services and/or sex exchange. Impulsive-antisocial psychopathic traits were related to erotic service provision. In contrast, participants high on both interpersonal-affective and impulsive-antisocial factors of psychopathy were most likely to consume services. These relations did not change when adjusting for substance use. Lastly, although associations between psychopathic traits and provision were not dependent on gender, the interpersonal-affective traits were associated with increased consumption of physical contact services in women, whereas consumption was similar in men across levels of these traits. Results inform college student involvement in erotic services and highlight personality correlates of engagement in understanding risks and benefits.

Liens entre les traits psychopathiques et le décodage multi-niveau des émotions auprès de la population non clinique : résultats préliminaires

ObjectivesSubclinical Psychopathic Personality traits (PPt) are found in non-clinical population (NCP). It has been hypothesized that PPt are associated with socio-affective deficit, such as emotions recognition. Although previous studies yielded mixed results, to our knowledge, none has been undertaken among a French-speaker NCP. Our research investigates multi-level emotions recognition accuracy through the three main channels: face, voice (prosody and semantic) and body posture. We hypothesized negative and significant associations and influences between SRP-4 scores and mean emotions recognition accuracy scores (total score and scores by emotion) in each channel. Materials and methodsThe sample consists of 34 individuals (22 women and 12 men). After signing a consent form, a short anamnesis was undertaken to collect sociodemographic information. Subclinical PPt were assessed using SRP-4. Afterwards, three computerized emotion recognition tasks were presented to participants in this order: NimStim (colorized, gendered, multi-ethnic stimuli morphed and dynamized in 10-second videos), GEMEP (gendered prosodic stimuli), gendered homemade scripts categorized using EMOTAIX and synthesized using Acapela-Box, and finally, BESST (monochromatic, gendered, static stimuli). Stimuli depicted the six basic emotions and participants were asked to make a forced choice between these six emotions labels. ResultsParametric (Bravais-Pearson's r) and Non-Parametric (Spearman's r) analyses indicated negative and significant correlations mainly between interpersonal-affective traits and the accurate recognition of all emotions, specifically anger (vocal semantic and body posture), fear (vocal semantic) and surprise (facial). However, a positive and significant correlation was found between interpersonal-affective traits scores, lifestyle-antisocial traits scores and the accurate recognition of disgust (facial). Significant correlations were followed by simple or multiple linear regressions. ConclusionsOur research partially confirmed previous findings about a negative associations and influence of PPt and accurate recognition of emotions. However, some unexpected results (disgust) or lack of expected results (fear), combined with limitations, invites us to consider our results with caution.

Associations Between Parental Psychopathic Traits, Parenting, and Adolescent Callous-Unemotional Traits.

Callous-unemotional (CU) traits (i.e., callousness, low empathy, shallow affect) have been conceptualized as a downward extension of the interpersonal and affective components of adult psychopathy and are associated with stable and severe antisocial behavior. Research suggests that CU traits are moderately heritable, but also influenced by environmental factors, particularly parenting. We examined associations among mother and father psychopathic traits, parenting practices, and offspring CU traits in a community sample of 550 adolescent twins (Mean age = 13.99years; SD 2.37; 56.4% male), incorporating multiple informants (mothers, fathers, child). Parental interpersonal-affective psychopathic traits were associated with adolescent CU traits and negative parenting (increased harshness, reduced warmth). Moreover, increased parental harshness and reduced warmth partially explained associations between parental interpersonal-affective traits and adolescent CU traits. There was also a significant direct effect specifically between mother interpersonal-affective traits and adolescent CU traits. Finally, using a twin difference design, we confirmed that adolescent CU traits were significantly impacted by non-shared environmental parenting influences (increased harshness, reduced warmth). These results suggest that mother and father interpersonal-affective traits appear to impact parenting practices and serve as risk factors for adolescent CU traits. However, many of the findings did not replicate when using cross-informant reports and were only present within single informant models, highlighting a role for shared informant variance as well. The results suggest the importance of accounting for parent personality in the development of effective parenting interventions for CU traits.

Effects of Psychopathy on Neurocognitive Domains of Impulsivity in Abstinent Opiate and Stimulant Users.

Background: Psychopathy and substance use disorders (SUDs) are both characterized by neurocognitive impairments reflecting higher levels of impulsivity such as reward-driven decision-making and deficient inhibitory control. Previous studies suggest that psychopathy may exacerbate decision-making deficits, but it may be unrelated to other neurocognitive impairments among substance dependent individuals (SDIs). The aim of the present study was to examine the role of psychopathy and its interpersonal-affective and impulsive-antisocial dimensions in moderating the relationships between dependence on different classes of drugs and neurocognitive domains of impulsivity.Method: We tested 693 participants (112 heroin mono-dependent individuals, 71 heroin polysubstance dependent individuals, 115 amphetamine mono-dependent individuals, 76 amphetamine polysubstance dependent individuals, and 319 non-substance dependent control individuals). Participants were administered the Psychopathy Checklist: Screening Version (PCL:SV) and seven neurocognitive tasks measuring impulsive choice/decision-making (Iowa Gambling Task; Cambridge Gambling Task; Kirby Delay Discounting Task; Balloon Analog Risk Task), and impulsive action/response inhibition (Go/No-Go Task, Immediate Memory Task, and Stop Signal Task).Results: A series of hierarchical multiple regressions revealed that the interpersonal-affective dimension of psychopathy moderated the association between decision-making, response inhibition and both amphetamine and heroin dependence, albeit differently. For amphetamine users, low levels of interpersonal-affective traits predicted poor decision-making on the Iowa Gambling Task and better response inhibition on the Stop Signal task. In contrast, in heroin users high interpersonal-affective psychopathy traits predicted lower risk taking on the Cambridge Gambling Task and better response inhibition on the Go/No-Go task. The impulsive-antisocial dimension of psychopathy predicted poor response inhibition in both amphetamine and heroin users.Conclusions: Our findings reveal that psychopathy and its dimensions had both common and unique effects on neurocognitive function in heroin and amphetamine dependent individuals. Our results suggest that the specific interactions between psychopathy dimensions and dependence on different classes of drugs may lead to either deficient or superior decision-making and response inhibition performance in SDIs, suggesting that psychopathy may paradoxically play a protective role for some neurocognitive functions in specific subtypes of substance users.

An elusive deficit: Psychopathic personality traits and aberrant attention to emotional stimuli.

Emotional stimuli are typically prioritized in competition for attention in healthy individuals. In contrast, there is evidence that individuals high in psychopathic traits fail to similarly prioritize emotional stimuli. With aberrant attention to emotional stimuli implicated in the development and maintenance of other psychopathologies, attentional insensitivity to emotional stimuli may also be important in the callous-unemotional responding seen in psychopathy. This study assessed emotional attention in association with psychopathic traits in a community sample (N = 121) using two commonly used emotional attention tasks-the dot probe and emotion-induced blindness tasks. Psychopathic personality traits were examined in association with two attention domains where emotional attention effects are reliably found: early perceptual competition and competition for spatial attention. Participants high in interpersonal-affective traits of psychopathy (boldness or meanness) exhibited emotional attention deficits in both domains when impulsive-antisocial traits were also high. These findings are discussed in the context of the inconsistent literature on attention to emotional stimuli in psychopathy. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Affective traits of psychopathy are linked to white-matter abnormalities in impulsive male offenders.

Psychopathy is a personality disorder typified by lack of empathy and impulsive antisocial behavior. Psychopathic traits may partly relate to disrupted connections between brain regions. The aim of the present study was to link abnormalities in microstructural integrity of white-matter tracts to the severity of different psychopathic traits in 15 male offenders with impulse control problems and 10 without impulse control problems. Psychopathic traits were assessed using the Psychopathy Checklist-revised (PCL-R). Diffusion-weighted MRI was used to examine white-matter tracts. Fractional anisotropy (FA), an index of white-matter integrity, was calculated for each voxel. Clusters of voxels showing a significant relationship with psychopathy severity were submitted to probabilistic tractography. No significant correlations between psychopathy severity and FA were present in the whole group of impulsive and nonimpulsive offenders. In impulsive offenders, interpersonal-affective traits (PCL-R Factor 1) were negatively correlated with FA in the anterior and posterior temporal lobe and orbitofrontal area. Further analyses indicated that elevated affective traits (PCL-R Facet 2) were specifically related to reduced FA in the right temporal lobe. Our findings suggest that white-matter abnormalities in temporal and frontotemporal tracts may be linked to the interpersonal-affective deficits of psychopathy in offenders with relatively severe impulse control problems. Our study offers novel insights into the relationships between the four facets of psychopathy and disrupted structural connectivity, and may provide new leads for further characterization of different subtypes of antisocial populations.

Psychopathic traits and politics: Examining affiliation, support of political issues, and the role of empathy

The relation of psychopathy to morality has been extensively examined, yet few studies have considered relations to political attitudes, which involve moral decision-making. We examined how psychopathic traits relate to political affiliation and opinions on political issues, using the triarchic conceptualization of psychopathy (Patrick, Fowles, & Krueger, 2009) and testing empathy components as mediators. Interpersonal-affective (Boldness and Meanness) traits were higher in Republicans compared to Democrats. Moreover, Boldness was associated with conservative opinions on economic issues, while Meanness evinced stronger relations to conservative opinions on social issues. Triarchic domains also evidenced unique associations to issues concerning minorities or discrimination. Further, empathy mediated relations between Meanness and decreased support for certain issues (e.g., affirmative action). Overall, psychopathy, particularly the interpersonal-affective traits, appear pertinent to political attitudes, while empathy deficits may statistically account for unique effects of Meanness.

Psychopathic traits are differentially associated with efficiency of neural communication.

Recent advances in the application of graph theory made it possible to quantify the efficiency of communication within a neural network, going beyond traditional connectivity methods that only identify the degree to which neural regions are connected. Psychopathic traits, namely, interpersonal-affective and impulsive-antisocial traits, have been linked to widespread and distinct disruptions in neural connectivity. The efficiency of neural communication for individuals high on these psychopathic traits, though, is unknown. In the present study, resting-state EEG was used to generate a connectivity matrix (i.e., weighted phase lag index) for multiple frequency bands. These connectivity matrices were examined using minimum spanning tree analysis, a graph theory approach that allows for the examination of neural efficiency, and regressed on Self-Report Psychopathy-Short Form scores (n = 158, unselected community sample). Results indicated that individuals with higher interpersonal-affective traits had significantly less efficient communication within alpha1 (i.e., long-range neural communication) and gamma (i.e., short-range neural communication) frequency bands. Conversely, individuals with higher impulsive-antisocial traits had more efficient communication within these same frequency bands. Overall, elevated psychopathic traits were related to alterations in the basic efficiency of neural communication. Moreover, this unique application of graph analysis provides a new avenue for inquiry into the mechanisms underlying the chronic and severe behavior of individuals with psychopathic traits.

Psychopathic traits are associated with reduced fixations to the eye region of fearful faces.

Impairments in processing fearful faces have been documented in both children and adults with psychopathic traits, suggesting a potential mechanism by which psychopathic individuals develop callous and manipulative interpersonal and affective traits. Recently, research has demonstrated that psychopathic traits are associated with reduced fixations to the eye regions of faces in samples of children and community-dwelling adults, however this relationship has not yet been established in an offender sample with high levels of psychopathy. In the current study, we employed eye-tracking with paradigms involving the identification and passive viewing of facial expressions of emotion, respectively, in a sample of adult male criminal offenders (n = 108) to elucidate the relationship between visual processing of fearful facial expressions and interpersonal and affective psychopathic traits. We found that the interpersonal-affective traits of psychopathy were significantly related to fewer fixations to the eyes of fear faces during the emotion recognition task. This association was driven particularly by the interpersonal psychopathic traits (e.g., egocentricity, deceitfulness), whereas fear recognition accuracy was inversely related to the affective psychopathic traits (e.g., callousness, lack of empathy). These findings highlight potential mechanisms for the subset of the interpersonal-affective traits exhibited by psychopathic individuals. (PsycINFO Database Record

Individuals with Psychopathic Traits view Distracting Neutral Information as Negatively Valenced

ABSTRACTResearch has shown that psychopathic individuals ignore information that is outside their goal-directed focus of attention. When affective information is goal-irrelevant, ignoring it results in a blunted affective response for psychopathic individuals. In cognitive science, though, an interesting phenomenon named inhibitory devaluation occurs in the context of neutral information. When neutral information is not relevant to a goal, ignoring it actually results in individuals' evaluating the neutral information as negatively valenced. In a sample of adult male offenders (N = 82), we used a pattern localizer task to examine the relationship between inhibitory devaluation and psychopathy (using scores on the Psychopathy Checklist-Revised). Results indicated that individuals high on the interpersonal-affective traits of psychopathy displayed significantly greater inhibitory devaluation, meaning that they ascribed more affective valence to goal-irrelevant neutral information. This finding provides further support for the importance of attention abnormalities in the neurobiology of psychopathy-related affective and interpersonal deficits.

Interactions cognition-émotion et personnalité psychopathique : des trajectoires distinctes vers les comportements antisociaux et violents

Researchers have long acknowledged heterogeneity among persons who exhibit antisocial and violent behaviours. The study of psychopathic personality or psychopathy can help elucidate this heterogeneity through examination of the different facets that constitute this disorder. In particular, the distinct correlates of the interpersonal-affective traits (Factor1) and the impulsive-antisocial traits (Factor2) of psychopathy suggest at least two possible pathways to antisocial behaviours. Building on basic studies in cognitive and affective neuroscience, we provide a focused, non-comprehensive review of work identifying the biopsychological mechanisms involved in these two pathways, with special attention to studies using event-related potential (ERP) methods. In specific, a series of studies are discussed which examined affective and cognitive processes that may distinguish offenders high on psychopathic traits from other offenders, with emphasis on alterations in emotion-cognition interactions related to each factor of psychopathy. The set of findings reviewed highlight a central conclusion: Factor1 represents a pathway involving reduced emotional responding, exacerbated by attentional abnormalities, that make for a more deliberate and emotionally insensitive offender profile. In contrast, Factor2 characterizes a pathway marked by emotional and behavioural dysregulation and cognitive control dysfunctions, particularly in emotional contexts. Implications for identifying etiological processes and the further understanding of antisocial and violent behaviours are discussed.

Gendered contexts: Psychopathy and drug use in relation to sex work and exchange.

Few scholars have examined psychopathology correlates of sex work. It has been suggested that sex work may reflect manifestations of impulsive-antisocial psychopathic traits (e.g., reckless disregard, delinquency) in women more than men. The current work examined relative contributions of drug dependence and distinct psychopathic features in relation to traditional forms of sex work (i.e., prostitution) in women, along with gender differences in psychopathy relationships with casual forms of sex exchange (i.e., trading sex for necessities). Study 1 included 171 community-dwelling women offenders, and Study 2 included 319 participants (42.3% women) with histories of drug use and/or violence. Participants completed the Psychopathy Checklist: Screening Version, prostitution was measured as self-report and/or public record data across studies, and sex exchange in Study 2 was assessed using a questionnaire based on prior research on sexual risk-taking. Findings across both studies demonstrated that although psychopathic traits, particularly impulsive-antisocial features, were associated with prostitution in women above the use of drugs, drug dependence did not moderate the relationship between psychopathic traits and prostitution in women. Analyses of Study 2 data revealed that impulsive-antisocial traits were associated with sex exchange at low, but not high, levels of interpersonal-affective traits across participants. As well, interpersonal-affective traits were significantly positively related to sex exchange in men and not significantly (and negatively) related in women. In sum, impulsive-antisocial traits related to prostitution among women, suggesting that women may manifest these traits within intimate contexts. Moreover, findings indicated gender differences in the manifestation of interpersonal-affective traits within sexual exchange contexts. (PsycINFO Database Record

Juror perceptions of the interpersonal-affective traits of psychopathy predict sentence severity in a white-collar criminal case

ABSTRACTRecent research has demonstrated jurors’ perceptions of a defendant’s psychopathic traits may impact their sentencing recommendations in death penalty and sexually violent predator civil commitment trials. Given the increasing media attention on white-collar crimes, the huge economic impact of such crimes on society, and the theoretical relationship between psychopathy and this type of crime, this research sought to investigate how juror perceptions of a white-collar defendant’s psychopathic traits may influence sentencing recommendations. Jury-eligible community members were given a brief description of a white-collar crime and asked to provide the judge with sentencing recommendations. Results largely supported previous findings in that perceiving a defendant to be highly psychopathic, particularly in terms of affective traits, predicted more punitive sentencing recommendations. Specifically, perceptions of the defendant’s remorselessness, lack of empathy, and failure to accept responsibility incrementally predicted harsher sentencing recommendations. These data lend support to the hypothesis that lay perceptions of psychopathic traits influence sentencing recommendations in white-collar criminal cases.

Gender differences in psychopathy links to drug use.

Although the relationship between psychopathic personality traits and substance use has received some attention (Hart & Hare, 1989; Smith & Newman, 1990), gender differences have not been thoroughly assessed. The current study examined whether gender modified the relationship between 2 criminally relevant constructs, (a) psychopathy and its factors and (b) drug use. A sample of 318 participants with criminal histories and recent substance use was assessed for psychopathy using the Psychopathy Checklist: Screening Version and for illicit drug use using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders. As expected, the impulsive-antisocial traits (Factor 2) of psychopathy were positively related to a number of drug use characteristics (symptoms, age of drug initiation, extent of drug experimentation), whereas the interpersonal-affective traits (Factor 1) showed a negative relationship with drug abuse symptoms and a positive relationship with age of first use. In terms of gender differences, analyses revealed that women showed a stronger association between Factor 1 traits and later age of initiation compared to men, and that Factor 2, and the antisocial facet in particular, were more strongly related to drug abuse in women than men. These findings suggest that psychopathic traits serve as both protective (Factor 1) and risk (Factor 2) correlates of illicit drug use, and Factor 1 may be especially protective in terms of initiation of drug use among women. These conclusions add to the growing literature on potential routes to substance use and incarceration in women.

Error-related processing in adult males with elevated psychopathic traits.

Psychopathy is a serious personality disorder characterized by dysfunctional affective and behavioral symptoms. In incarcerated populations, elevated psychopathic traits have been linked to increased rates of violent recidivism. Cognitive processes related to error processing have been shown to differentiate individuals with high and low psychopathic traits and may contribute to poor decision making that increases the risk of recidivism. Error processing abnormalities related to psychopathy may be attributable to error-monitoring (error detection) or posterror processing (error evaluation). A recent 'bottleneck' theory predicts deficiencies in posterror processing in individuals with high psychopathic traits. In the current study, incarcerated males (n = 93) performed a Go/NoGo response inhibition task while event-related potentials (ERPs) were recorded. Classic time-domain windowed component and principal component analyses were used to measure error-monitoring (as measured with the error-related negativity [ERN/Ne]) and posterror processing (as measured with the error positivity [Pe]). Psychopathic traits were assessed using Hare's Psychopathy Checklist-Revised (PCL-R). PCL-R Total score, Factor 1 (interpersonal-affective traits), and Facet 3 (lifestyle traits) scores were positively related to posterror processes (i.e., increased Pe amplitude) but unrelated to error-monitoring processes (i.e., ERN/Ne). These results support the attentional bottleneck theory and further describe deficiencies related to elevated psychopathic traits that could be beneficial for new treatment strategies for psychopathy.

Elevated Psychopathy Scores Among Mixed Sexual Offenders

Past research has revealed a relationship between sexual offending and psychopathy. Notably, offenders who sexually assault a minor as well as an adult (mixed offenders) score higher on the Psychopathy Checklist–Revised (PCL-R) than child sex offenders, rapists, and nonsex offenders. Moreover, both PCL-R Factor 1 (interpersonal-affective traits) and PCL-R Factor 2 (impulsive-antisocial traits) scores have been implicated in explaining these higher psychopathy scores. Using data from 2,514 male prisoners, focusing on a subset of 40 mixed offenders, we attempted to replicate and clarify these findings. As predicted, mixed offenders scored higher on PCL-R total and Factor 1 than other offender groups. Given this distinctive profile, greater understanding of the association between these psychopathic traits and mixed sexual offending may be crucial for evaluating and treating sex offenders as well as for reducing victimization.

Response monitoring and adjustment: differential relations with psychopathic traits.

Studies on the relation between psychopathy and cognitive functioning often show mixed results, partially because different factors of psychopathy have not been considered fully. Based on previous research, we predicted divergent results based on a 2-factor model of psychopathy (interpersonal-affective traits and impulsive-antisocial traits). Specifically, we predicted that the unique variance of interpersonal-affective traits would be related to increased monitoring (i.e., error-related negativity) and adjusting to errors (i.e., posterror slowing), whereas impulsive-antisocial traits would be related to reductions in these processes. Three studies using a diverse selection of assessment tools, samples, and methods are presented to identify response monitoring correlates of the 2 main factors of psychopathy. In Studies 1 (undergraduates), 2 (adolescents), and 3 (offenders), interpersonal-affective traits were related to increased adjustment following errors and, in Study 3, to enhanced monitoring of errors. Impulsive-antisocial traits were not consistently related to error adjustment across the studies, although these traits were related to a deficient monitoring of errors in Study 3. The results may help explain previous mixed findings and advance implications for etiological models of psychopathy.

Gender, psychopathy factors, and intimate partner violence.

The present study sheds light on relationships between distinct psychopathic traits and perpetration of intimate partner violence (IPV) in women versus men. Men and women with recent drug and/or violence histories (N = 250) were assessed for psychopathic traits using the Psychopathy Checklist: Screening Version and for their and their partner's use of IPV with the Revised Conflict Tactics Scale. The first goal was to examine the moderating role of gender in psychopathy factor relationships to IPV. Although both the interpersonal-affective traits (Factor1) and the impulsive-antisocial traits (Factor 2) of psychopathy were related to higher frequency of IPV perpetration, the relationship between Factor 1 and IPV was stronger in men. Our second goal examined the moderating role of psychopathy traits in the relationship between partner's perpetration of IPV and participant perpetration (mutual violence) in the 2 genders. Relationships between partner- and self-IPV were similar at both low and high levels of Factor 1 in men, although the partner- and self-IPV relationship was significantly stronger among women at low relative to high levels of Factor 1. The relationship between partner- and self-IPV was stronger at high levels of Factor 2 in men, whereas Factor 2 did not moderate mutual violence in women. These results indicate that relationships between psychopathy factors and IPV differ by gender, with psychopathy generally exacerbating IPV perpetration in men and Factor 1 traits playing a unique role in mutual violence in women. These findings add to the literature on female psychopathy and have important implications for future research on gender and IPV. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Predicting self-reported total, aggressive, and income offending with the Youth Version of the Psychopathy Checklist: Gender- and factor-level interactions.

The purpose of this study was to determine whether gender moderates the interaction between Factor 1 (F1: core interpersonal-affective traits of psychopathy) and Factor 2 (F2: social deviance and disinhibition) of the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson, & Hare, 2003) in predicting future offending. A group of 806 (679 boys, 127 girls) adjudicated delinquents from the Pathways to Desistance study (Mulvey, 2013) completed the PCL:YV and were followed for 7 years. When gender and the PCL:YV factor scores were entered into the 1st step of a hierarchical regression analysis, only gender and Factor 2 successfully predicted total, aggressive, and income offending. The 2-way (F1 × F2, F1 × Gender, F2 × Gender) and 3-way (F1 × F2 × Gender) interactions entered at Steps 2 and 3, respectively, failed to achieve significance. Because several of the interactions involving gender approached statistical significance, male and female data were analyzed separately. A significant interaction between Factors 1 and 2 for income offending in the female subsample surfaced, but contrary to previous research, Factor 2 predicted income offending in youth scoring low, rather than high, on Factor 1. Overall, these results indicate that Factor 2 is the component responsible for the bulk of predictive efficacy observed with the PCL:YV in males as well as in females and that if Factor 1 moderates Factor 2 in females it does so in a manner opposite to what has been proposed by advocates of the PCL F1 × F2 interaction hypothesis.

Confiabilidad y validez de la Escala de Psicopatía Revisada de Hare (PCL-R) en la población carcelaria cubana

Las propiedades psicométricas de la Escala de Psicopatía de Hare (PCLR) han sido estandarizadas en diferentes países. Este artículo evalúa si la PCL-R puede ser validada en la población carcelaria cubana. La muestra estuvo compuesta por 124 sujetos, presos por cometer crímenes violentos, a quienes se les aplicó la adaptación española de Moltó et al. (2000). La confiabilidad y la consistencia interna de la escala fueron similares a otros estudios realizados. El análisis factorial mostró una estructura de dos factores, donde el Factor 1 representa los rasgos que describen la conducta antisocial y el Factor 2, los rasgos que describen las relaciones interpersonales y la afectividad. Los dos factores exhiben una alta correlación con distintos instrumentos validados que miden rasgos de personalidad, lo que confirma la validez del constructo.
