Psychopathy traits and their association with depression, anxiety and sociodemographic factors in Peruvian medical students

Introduction: Psychopathic traits harm the professional development and interpersonal relations of the general population, including healthcare professionals. This can be seen not only in already licensed physicians, but it may also be evidenced since their formative years as medical students. Objective: To evaluate the presence of psychopathic traits in a sample of Peruvian medical students and determining whether there is an association between sociodemographic and mental health (depression and anxiety) characteristics on the levels of psychopathic traits. Methods: A cross-sectional study was conducted on 497 students of a Peruvian medical school. Through online questionnaires, the following instruments were self-administered: Levenson Self-Report Psychopathy Scale (LSRP), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7). Results: 19.7% of the participants were in the psychopathic group. The variables associated with a higher frequency of belonging to the psychopathic group were male sex (aPR = 2.10, 95% CI: 1.58-2.79, p < 0.05), having clinically relevant depressive (aPR = 2.05, 95% CI: 1.41-2.96, p < 0.05) and anxious symptoms (aPR = 1.46, 95% CI: 1.01-2.09, p < 0.05). Conclusions: Medical students of the sample studied show a high prevalence of psychopathy traits. The variables associated with a higher frequency of belonging to the psychopathic group were male sex, having clinically relevant depressive symptoms, and anxiety symptoms. More involvement on behalf of the medical school is necessary as to the identification of the psychopathic traits in medical students.

Psychopathic traits modulate functional connectivity during pain perception and perspective-taking in female inmates

The ability to share and understand the distress of others is critical for successful social interactions and is a fundamental building block of morality. Psychopathy is a personality disorder that includes lack of empathy and concern for others. In the present study, functional MRI was used to examine neural responses and functional connectivity associated with empathy and affective perspective-taking in female inmates (N = 109) with various levels of psychopathic traits, as measured with Psychopathy Checklist-Revised (PCL-R). Participants viewed hands and feet in painful or non-painful situations while adopting a first person or third person perspective. All participants demonstrated robust neural responses in anterior insula (aINS), anterior cingulate (ACC), temporoparietal junction (TPJ) and supplementary motor area (SMA) when viewing pain, both during imagine-self and imagine-other blocks. Psychopathy shifted the functional connectivity seeded in core nodes of the salience and social cognition networks. Perceiving stimuli depicting somatic pain led to decreased functional coupling from right temporoparietal junction to superior temporal sulcus, which correlated with scores on PCL-R Factor 1 (Affective/Interpersonal). In contrast, connectivity from right insula to precuneus increased with Factor 2 (Lifestyle/Antisocial) scores. When adopting a third-person perspective, psychopathic traits modulated connectivity from the social cognition network, but not the salience network, with Factor 1 scores associated with increased connectivity to sensorimotor cortex and temporal pole, while Factor 2 scores were associated with decreased connectivity with ACC/SMA and inferior frontal gyrus. Overall, these results demonstrate that psychopathic traits in incarcerated females are associated with atypical functional connectivity within the salience network during pain-empathy processing and within the social cognition network during affective perspective-taking.

Examining Individual Differences in Social Reward Valuation: a Person-Based Approach

AbstractSocial reward refers to the motivational and pleasurable aspects of our interactions with other people. While some people experience social encounters as pleasurable, others experience them as aversive. However, the current knowledge on individual differences in social reward valuation in relation to pro- and antisocial personality characteristics is limited. The Social Reward Questionnaire (SRQ) was developed to assess individual differences in the value of different types of social rewards. First, the present study examined the validity and reliability of the Dutch version of the SRQ in a Dutch and Flemish community sample (N = 1892). Second, using latent profile analysis (LPA), it was investigated whether subgroups of participants existed with distinctive patterns of social reward valuation, and whether these subgroups differed in their level of psychopathic traits, aggression, and social anxiety. The results confirmed the original six-factor structure and showed good reliability and validity. The LPA identified four classes of individuals, labelled as: Low Social Interest, High Social Interest, Undifferentiated Social Reward-seekers, and Socially Cruel. These classes were further typified by distinct levels of psychopathy, reactive and proactive aggression, and social anxiety. The present findings contribute to our understanding of individual variability in the underlying motives of social behaviors.

Psychopathic traits influence threat avoidance in a community sample independent of testosterone.

Psychopathy is a personality construct that encompasses a constellation of traits reflecting emotional dysfunction and antisocial behavior. Individuals with elevated levels of psychopathic traits have shown abnormal affective processing. Studies with psychopathic offenders suggested that this is a result of altered automatic social approach-avoidance tendencies. The goal of the current study was to increase the insight into the underlying mechanism of affective processes in community-dwelling individuals with a high level of psychopathic traits by studying approach and avoidance behavior in an experimental setting. Furthermore, given its link with aggression and threat approach, testosterone was measured to investigate a possible mediatory role. Eighty-seven healthy individuals performed a computerized affective approach-avoidance task in which they pushed or pulled emotional faces using a joystick. The results showed that high levels of psychopathic traits corresponded with diminished threat avoidance to angry faces, as was found previously in psychopathic offenders. Although endogenous testosterone was positively associated with the level of psychopathic traits, it did not mediate the effect of psychopathic traits on threat avoidance. We propose that an increased understanding of the interplay between different neuroendocrine mechanisms could lead to a better insight into the underlying mechanism of abnormal threat avoidance in individuals with high levels of psychopathic traits.

Altered power spectra in antisocial males during rest as a function of cocaine dependence: A network analysis

Abnormalities in the spectral power of offenders’ neural oscillations have been noted within select Resting-State Networks (RSNs); however, no study has yet evaluated the influence of cocaine dependence, drug use severity, and psychopathic traits on these abnormalities. To this end, the present study compared rest-related power spectral characteristics between two groups of offenders (with and without a DSM-IV-TR cocaine-dependence diagnosis) and a non-offender control group. Results indicated that both offender groups presented with lower low frequency power ratio (LFPR) scores (i.e. across all RSNs) than non-offenders. These differences in LFPR scores were due to both higher high-frequency power (0.15-0.25 Hz; within seven (in non-dependent offenders) and five (in cocaine-dependent offenders) of eight investigated networks) and decreased low-frequency power (0.01-0.10 Hz; within six (in non-dependent offenders) and one (in cocaine-dependent offenders) of eight investigated networks) compared to non-offenders. Thus, both cocaine-dependent and non-dependent offenders displayed abnormal neural oscillations, suggesting that these oscillatory abnormalities could exist as neurobiological features associated with offender status. Offenders’ LFPR levels correlated with lifetime years of cocaine use, but not with the level of psychopathic traits. These findings supplement our knowledge regarding the influence of substance use on resting-state activity in offenders; moreover, they provide further indication of the importance of evaluating shared/unique variance associated with drug use and pyschopathic personality traits.

Somatic Marker Production Deficits do not Explain the Relationship between Psychopathic Traits and Utilitarian Moral Decision Making.

In moral dilemma tasks, high levels of psychopathic traits often predict increased utilitarian responding—specifically, endorsing sacrificing one person to save many. Research suggests that increased arousal (i.e., somatic marker production) underlies lower rates of utilitarian responding during moral dilemmas. Though deficient somatic marker production is characteristic of psychopathy, how this deficit affects the psychopathy–utilitarian connection remains unknown. We assessed psychopathic traits in undergraduates, as well as behavioral performance and skin conductance level reactivity (SCL-R; a measure of somatic marker production) during a moral dilemma task. High psychopathic traits and low SCL-R were associated with increased utilitarian decisions in dilemmas involving direct personal harm. Psychopathic traits were unrelated to SCL-R, nor did SCL-R mediate the relationship between psychopathy and utilitarianism. The present study did not find evidence that somatic marker production explains the connection between utilitarianism and psychopathy in a college population. Further research is necessary to identify the neural mechanisms relating psychopathy and moral decision-making in nonclinical samples.

Work and alcohol addiction among sports coacheswithin the context of psychopathy

Excessive involvement in work, or workaholism, is classifi ed as obsessive-compulsive disorder, which is included in the group of anxiety disorders. It is indicated that workaholism is associated with forcing oneself to work, lack of control over work-related habits, which may lead to neglecting main life activities (Łuczak, 2009; Rowicka, 2015). Due to increasing tension, anxiety, depressed mood and diffi culties in interpersonal relationships, people who are excessively involved in their work are at an increased risk of becoming addicted to psychoactive substances. Thanks to stimulants, they are able to reduce increasing psychological discomfort in a short time, but in the long run –they fall victim to addiction. Attention should be especially paid to the group of people who are described as highly functioning alcoholics, i.e. people who are generally perceived as resourceful, independent and organised. The aim of the study was to check whether the relationship between alcohol abuse and workaholism in sports coaches is modified by their level of psychopathic traits. In thestudy, 96 individual and team sports coaches (Mage = 31.85±10.56) with experience from 1 to 42 years (Mexp = 8.66±8.51) were examined. The Audit (alcoholism), TriPM (psychopathy) andWorkBAT (workaholism) tests were used. The conducted moderation analyses showed that the relationship between alcohol consumption and job satisfaction changes with the increase in the level of 2 features of psychopathy - boldness (Beta=-0.28; t=-2.69; p=0.009) and disinhibition (Beta=0.21; t=2.12; p=0.037). In coaches with a high level of disinhibition, along with the increase in work enjoyment, the use of alcohol increases, while in the case of people with a high level of boldness, the higher the level of work enjoyment, the lower the consumption of alcohol. It was also found that with the increase in boldness, the relationship between alcohol use and excessive involvement in work changes (Beta=-0.28; t=-2.58; p=0.012). For people with a high level of boldness, the more they are involved in work and the less they are prone to alcoholism. Among the studied sportscoaches, psychopathic traits constituted a moderator of the relationship between alcohol abuse and workaholism. A high level of boldness can be a protective factor against the risk of heavy drinking, while a high level of disinhibition increases this risk, especially among those whose workaholism is associated with high work enjoyment.

Empathy and psychopathic traits as predictors of selection into business or psychology disciplines

ObjectiveThe attraction, selection, and attrition model posits that individuals actively self‐select into vocational and educational environments based on their personality traits and values. The present study investigated whether pre‐existing empathy and psychopathic personality trait differences in newly enrolled first year undergraduate students predicted selection into psychology and business vocational pathways respectively.MethodAn online self‐report survey collected data on levels of psychopathic traits and empathy from 380 newly enrolled first year business and psychology undergraduate students to examine whether these pre‐existing personality traits could predict academic discipline attraction and selection.ResultsBinary logistic regression analysis partially supported the proposed hypotheses. Cognitive empathy, gender, and social desirability scores were found to be significant predictors of student discipline, with females, those with higher cognitive empathy and lower social desirability scores more likely to be attracted and selected into a psychology rather than a business degree. Small to moderate effect size differences were observed, with psychology students reporting significantly higher cognitive empathy (d = 0.53) and lower interpersonal psychopathy (d = 0.27) than business students.ConclusionsFindings highlight specific personality trait differences present between newly enrolled business and psychology students and the importance of these pre‐existing differences in student vocational decision‐making. It is anticipated that findings may assist vocational and career counsellors in guiding prospective students in the direction of a vocational pathway that is best suited to their personality, as this is likely to result in increased student satisfaction and self‐esteem whilst reducing student attrition.

The Effect of Reduced Learning Ability on Avoidance in Psychopathy: A Computational Approach.

Individuals with psychopathy often show deficits in learning, which often have negative consequences. Several theories have been proposed to explain psychopathic behaviors, but the learning mechanisms in psychopathy are still unclear. To clarify the learning anomalies in psychopathy, we fitted reinforcement learning (RL) models to behavioral data. We conducted two experiments to examine the effect of psychopathy as a group difference (Experiment 1) and as a continuum (Experiment 2). Forty-three undergraduates (in Experiment 1) and fifty-five undergraduate and graduate students (in Experiment 2) performed a go/no-go based learning task with accompanying rewards or punishments. Although we observed no differences in learning performance among the levels of psychopathic traits, the learning rate for the positive prediction error in the loss domain was lower for those with high-psychopathic trait than for those with low-psychopathic trait. This finding indicates that individuals with high-psychopathic traits update an action value less when they avoid a negative outcome. Our model can represent previous theories under a computational framework and provide a new perspective on impaired learning in psychopathy.

Do psychopathic traits impair autobiographical memory for emotional life experiences?

ABSTRACTWe examined the relationship between psychopathic traits and autobiographical memory (AM) for emotional life experiences in both a community (Study 1) and forensic sample (Study 2). Considering that psychopathy is traditionally linked to an impairment in the processing of emotion, we hypothesised an emotional deficit of AM in individuals with high levels of psychopathic traits. Participants in both samples were asked to recall an emotionally charged event, and were then administered the Psychopathic Personality Inventory-Revised, the Flashbulb Memory Checklist, and the Autobiographical Memory Characteristics Questionnaire. A linguistic content analysis was applied to inmates’ memory transcriptions (Study 2). Only in the forensic sample, was self-centered impulsivity found to be positively related to the linguistic use of mood terms, and negatively related to the linguistic use of cognitive labels. Furthermore, high levels of fearless dominance were associated to a low emotional attribution to the event and its implications, and highly confident and coherent memory. Lastly, coldheartedness was the psychopathic trait most associated to a deficit in emotional AM, in terms of a lack of hedonic labels and contextual details, a poor emotional evaluation of the event and its implications. The current results encourage further investigation concerning AM in psychopathic traits.

Psychopathic traits and gender as moderators of the parental arrest-proactive aggression link

This study explored the association between parental arrest and two functions of aggression (i.e., reactive and proactive aggression) among 797 Singaporean adolescents. The moderating effects of psychopathic traits and gender were also investigated in the parental arrest-reactive/proactive aggression link. Parental arrest was found to be significantly and positively related to both reactive and proactive aggression, especially proactive aggression. Psychopathic traits strengthened the link between parental arrest and proactive aggression in adolescents with stronger effects for girls in this Singaporean sample. These findings point to the importance of early intervention with respect to girls who display high levels of psychopathic traits, especially when they also have parents with a prior arrest history, so as to reduce their levels of proactive aggression.

Reduced engagement of the anterior cingulate cortex in the dishonest decision-making of incarcerated psychopaths.

A large body of research indicates that psychopathic individuals lie chronically and show little remorse or anxiety. Yet, little is known about the neurobiological substrates of dishonesty in psychopathy. In a sample of incarcerated individuals (n = 67), we tested the hypothesis that psychopathic individuals show reduced activity in the anterior cingulate cortex (ACC) when confronted with an opportunity for dishonest gain, reflecting dishonest behavior that is relatively unhindered by response conflict. During functional magnetic resonance imaging, incarcerated offenders with different levels of psychopathy performed an incentivized prediction task wherein they were given real and repeated opportunities for dishonest gain. We found that while incarcerated offenders showed a high rate of cheating, levels of psychopathic traits did not influence the frequency of dishonesty. Higher psychopathy scores predicted decreased activity in the ACC during dishonest decision-making. Further analysis revealed that the ACC was functionally connected to the dorsolateral prefrontal cortex, and that ACC activity mediated the relationship between psychopathic traits and reduced reaction times for dishonest behavior. These findings suggest that psychopathic individuals behave dishonestly with relatively low levels of response conflict and that the ACC may play a critical role in this pattern of behavior.

Psychopathy Moderates the Relationship between Orbitofrontal and Striatal Alterations and Violence: The Investigation of Individuals Accused of Homicide.

Brain structural abnormalities in the orbitofrontal cortex (OFC) and striatum (caudate and putamen) have been observed in violent individuals. However, a uni-modal neuroimaging perspective has been used and prior findings have been mixed. The present study takes the multimodal structural brain imaging approaches to investigate the differential gray matter volumes (GMV) and cortical thickness (CTh) in the OFC and striatum between violent (accused of homicide) and non-violent (not accused of any violent crimes) individuals with different levels of psychopathic traits (interpersonal and unemotional qualities, factor 1 psychopathy and the expressions of antisocial disposition and impulsivity, factor 2 psychopathy). Structural Magnetic Resonance Imaging data, psychopathy and demographic information were assessed in sixty seven non-violent or violent adults. The results showed that the relationship between violence and the GMV in the right lateral OFC varied across different levels of the factor 1 psychopathy. At the subcortical level, the psychopathy level (the factor 1 psychopathy) moderated the positive relationship of violence with both left and right putamen GMV as well as left caudate GMV. Although the CTh findings were not significant, overall findings suggested that psychopathic traits moderated the relationship between violence and the brain structural morphology in the OFC and striatum. In conclusion, psychopathy takes upon a significant role in moderating violent behavior which gives insight to design and implement prevention measures targeting violent acts, thereby possibly mitigating their occurrence within the society.

The influence of academic discipline on empathy and psychopathic personality traits in undergraduate students

The Attraction, Selection and Attrition (ASA) model posits that people are attracted to organizations that embody similar personality traits and values to their own. These traits are thought to be further shaped by the organization's culture, ultimately creating a homogenous workforce within the organization (Schneider, 1987). This research applies the ASA model to investigate whether specific university disciplines have an impact on the development of psychopathic traits and empathy in students. An online survey collected data on levels of psychopathic traits and empathy from 259 psychology and business undergraduate students to examine whether group level variations were present across years and disciplines. Generalized Linear Mixed Modelling analyses supported the hypothesized interaction effects of year of study and discipline for psychopathic traits only. Moderate-large discipline effect sizes were noted, with psychology students reporting significantly higher levels of cognitive (d=0.77) and total empathy (d=0.74) than business students. Additionally, business students reported significantly higher levels of affective, antisocial, interpersonal and total psychopathic traits than psychology students (d=0.36–0.45). Findings provide support for the attraction and selection components of the ASA model. Implications of these findings are discussed in the context of the model and self-selection.

Are individuals with higher psychopathic traits better learners at lying? Behavioural and neural evidence

High psychopathy is characterized by untruthfulness and manipulativeness. However, existing evidence on higher propensity or capacity to lie among non-incarcerated high-psychopathic individuals is equivocal. Of particular importance, no research has investigated whether greater psychopathic tendency is associated with better ‘trainability’ of lying. An understanding of whether the neurobehavioral processes of lying are modifiable through practice offers significant theoretical and practical implications. By employing a longitudinal design involving university students with varying degrees of psychopathic traits, we successfully demonstrate that the performance speed of lying about face familiarity significantly improved following two sessions of practice, which occurred only among those with higher, but not lower, levels of psychopathic traits. Furthermore, this behavioural improvement associated with higher psychopathic tendency was predicted by a reduction in lying-related neural signals and by functional connectivity changes in the frontoparietal and cerebellum networks. Our findings provide novel and pivotal evidence suggesting that psychopathic traits are the key modulating factors of the plasticity of both behavioural and neural processes underpinning lying. These findings broadly support conceptualization of high-functioning individuals with higher psychopathic traits as having preserved, or arguably superior, functioning in neural networks implicated in cognitive executive processing, but deficiencies in affective neural processes, from a neuroplasticity perspective.

Effects of Mental Health and Neuroscience Evidence on Juror Perceptions of a Criminal Defendant: the Moderating Role of Political Orientation.

Several recent studies have examined the effects of mental health and neuroscientific evidence on attitudes toward criminal defendants, suggesting that these factors may influence juror decision-making in meaningful ways. Few studies to date have manipulated both of these variables while also considering theoretically important individual difference variables (e.g., political orientation). Using a criminal case simulation, this study manipulated the presence of evidence concerning mental disorders (psychopathy and schizophrenia) and increasing levels of neuroscientific detail regarding a defendant's brain injury, and examined verdicts and sentencing recommendations in over 400 persons attending jury duty. Main effects were detected for mental health testimony and political orientation, although interactions were noted as well. More negative reactions to defendants labeled as psychopaths were relatively consistent, whereas participants who identified as liberal generally were less punitive towards a defendant identified as schizophrenic than were more conservative jurors. Consistent with other recent research, juror perceptions of the defendant's level of psychopathic traits (independent of the effects of the experimental manipulations) predicted guilty verdicts and longer sentencing recommendations.

Physiological Arousal and Juvenile Psychopathy: Is Low Resting Heart Rate Associated with Affective Dimensions?

A wealth of past research has examined the relationship between low physiological arousal and violence or antisocial behavior. Relatively little research; however, has examined the relationship between low physiological arousal and psychopathic traits, with even less having been conducted with juveniles. The current study attempts to fill this gap by evaluating juveniles' physiological arousal using resting heart rate and their levels of psychopathic traits. Results suggest that there is indeed an inverse relationship between resting heart rate and the affective traits of psychopathy (Uncaring, Callousness, and Unemotionality) as well as Thrill or Sensation Seeking in males. No significant relationship was found in females. Implications of the findings as well as study limitations and future directions are discussed.

Not just ‘callous-unemotional’: Psychopathic traits are associated with emotion dysregulation dimensions

IntroductionHistorically, psychopathic individuals have mainly been described as characterized by pervasive callous-unemotional traits, with dramatic implications for clinical and forensic practices – such as the tendency to deem psychopathic individuals as untreatable. However, recent evidence with community samples have highlighted that psychopathic traits may be in fact related to emotion dysregulation rather than being the mere reflection of an underlying ‘unemotionality’. Yet, it is no clear if this association extends to populations with more severe forms of psychopathy (i.e., offenders).ObjectivesWe wanted to replicate previous evidence of an association between emotion dysregulation and psychopathic traits in a sample of incarcerated offenders.AimsTo investigate the associations among emotion dysregulation dimensions and psychopathic traits, exploring similarities and differences between the Interpersonal-Affective and the Antisocial-Lifestyle facets of psychopathy.MethodsA sample of male offenders incarcerated in Italian jails completed the Self-Report Psychopathy Scale (SRP-4; Paulhus, Neumann, & Hare, 2015) and the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004).ResultsIn line with the expectations, emotion dysregulation dimensions did predict higher levels of psychopathic traits. Structural Equation Modelling revealed that selected dimensions of emotion dysregulation were associated with different facets of psychopathy.ConclusionsBased on our findings, we argue that psychopathic traits may be associated to a certain extent with emotion dysregulation, and thus a focus on improving emotion regulation skills may hold the promise to dampen the therapeutic pessimism when dealing with psychopathic offenders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Psychopathic Traits and Social Cooperation in the Context of Emotional Feedback

Much is known about the affective deficits that characterise psychopathic traits. However, relatively little research has investigated psychopathy using paradigms that model social dynamics in interpersonal contexts. This study examined the association between psychopathic traits and social cooperation in an iterated prisoner's dilemma (IPD) paradigm, and tested the impact of affective cues from a co-player on participant cooperation. A sample of male university students participated in a block of standard IPD trials (game 1) followed by a block comprising a novel condition in which participants were provided with feedback on the emotional state of a bogus co-player throughout game-play (game 2). Whereas participants with low levels of psychopathic traits exhibited increased social cooperation in the context of affective feedback, poor cooperation was uniquely predicted by high levels of psychopathic traits. Findings are discussed in relation to recent accounts of psychopathy that emphasise attention-based mechanisms and empathic dysfunction.

Reward: Empirical Contribution: Temporal Discounting and Conduct Disorder in Adolescents

The current study examined temporal discounting (the decrease in subjective reward value as a function of increasing delay) in youths with conduct disorder (CD) and the extent to which this was modulated by level of psychopathic traits. In the temporal discounting task, participants were asked to choose between immediate rewards of varying values and a larger reward, held at a constant value ($10), whose receipt was delayed by different time intervals across trials (e.g., 7 days, 360 days). The level of immediate reward necessary for selection over the larger, delayed reward is the measure of temporal discounting. Forty-six youths (21 with CD and 25 healthy youths) participated in this study. Compared with healthy youths, youths with CD chose significantly smaller amounts of immediate reward rather than the larger future rewards. This was the case even in youths with CD without comorbid attention-deficit/hyperactivity disorder. However, level of psychopathic traits did not modulate temporal discounting in this sample. These results are discussed in terms of neurobiological models of CD and psychopathic traits.
