Psychopathy and dangerousness: An umbrella review and meta-analysis

Psychopathy and gaze cueing

BACKGROUND AND OBJECTIVES

Psychopathic traits - and especially callous affective features - have been linked to altered processing of others' emotional expressions, and to reduced attention to the eyes. Despite the importance of gaze cueing (i.e., the tendency to orient attention toward where someone else is looking) for social functioning, few studies have investigated relationships between psychopathic traits and gaze cueing, and whether facial emotional expression influence these relationships, obtaining mixed results. To address this gap, the present study aimed to evaluate associations between psychopathic traits and gaze cueing for emotional and neutral expressions.

METHODS

65 non-clinical male participants (Mage = 27.3 years) completed two self-report measures of psychopathy and performed laboratory tasks to assess gaze-cueing for emotional vs. neutral faces and an arrow-cueing task as a comparison.

RESULTS

Linear mixed models showed no significant associations of emotional (versus neutral) expressions, or psychopathy trait dimensions, with either gaze cueing or arrow cueing.

LIMITATIONS

Reliance on a convenience sample of non-clinical men, assessed with self-reports measures of psychopathy, and using static emotional stimuli limit the generalizability of our findings.

CONCLUSIONS

Findings suggest that psychopathic traits are not associated with individual differences in following others' gaze to direct attention, and that there was no advantage for affective relative to neutral expressions.

Psychopathy Scores Predict Recidivism in High-risk Youth: A Five-year Follow-up Study

Psychopathic traits have been associated with rearrest in adolescents involved in the criminal legal system. Much of the prior work has focused on White samples, short follow-up windows, and relatively low-risk youth. The current study aimed to evaluate the utility of the Hare Psychopathy Checklist: Youth Version (PCL:YV) for predicting general and violent felony recidivism in a large sample of high-risk, predominantly Hispanic/Latino, male adolescents (n = 254) with a five-year follow-up period. Results indicated higher PCL:YV scores and lower full-scale estimated IQ scores were significantly associated with a shorter time to felony and violent felony rearrest. These effects generalized to Hispanic/Latino adolescents (n = 193)-a group that faces disproportionate risk of being detained or committed to juvenile correctional facilities in the U.S. These results suggest that expert-rated measures of psychopathic traits and IQ are reliable predictors of subsequent felony and violent felony rearrest among high-risk male adolescents.

Paraphilic disorders, psychopathy, and those who sexually offend: a narrative review of treatment modalities

Despite its critical importance, the treatment of paraphilic disorders remains an often-overlooked domain both in clinical research and practice. Challenges have arisen in the morphing understanding of paraphilias and paraphilic disorders, now considered separate concepts, and efforts at developing a more nuanced understanding of these conditions is ongoing, resulting in a muddled history that can frustrate efforts at study and treatment. These populations are by nature more heterogeneous than may first be obvious-particularly among those with comorbid psychopathic traits-and may require a more nuanced and individualized approach based on risk, needs, and responsivity to treatment. Until recently, there were few guidelines to assist clinicians when confronted with these complicated clinical pictures and a sea of discrete studies investigating various biological and non-biological interventions. Treatments range from several variations of psychotherapy and behavioral therapies to SSRIs, anti-androgenic medications, to orchiectomy, all displaying varying degrees of effectiveness and evidence across decades of research. Fortunately, recent efforts to collate these studies supported by a task force of the World Federation of Societies of Biological Psychiatry (WFSBP) have helped form a better-focused and better-evidenced picture of effective treatments and the unique challenges faced by (and with) these populations.

What is the Best Source of Information for Psychopathic Traits in Youth? A Review and Meta-analysis of Self- and Other-Reported Psychopathic Traits and Their Association with Negative Outcomes

Child psychopathic traits appear to be associated with negative outcomes. Despite the study of youth psychopathy often relying on multiple reporters (e.g., child, caregivers, teachers), there is limited insight into how much information these various sources contribute and moreover, how this information is integrated. The present study sought to address this gap in the literature by examining the magnitude of relationships between self- and other-reported youth psychopathy and negative outcomes (e.g., delinquency, aggression) using a meta-analytic approach. Results revealed a moderate association between psychopathic traits and negative outcomes. Moderator analyses showed a greater relationship for other- than self-reported psychopathy, although not to a substantive extent. Results further indicated the magnitude of the overall psychopathy-negative outcomes association was stronger for externalizing than internalizing outcomes. Study findings can inform improvements in the assessment of youth psychopathy across research and practice, in addition to advancing our understanding of the utility of psychopathic traits in the prediction of clinically relevant outcomes. This review also provides guidance for future multisource raters and source-specific information in the study of psychopathy in youth.

Psychopathic Traits in a Swedish Court-Ordered Forensic Sample: Preferential Associations of Boldness, Meanness, and Disinhibition

The construct validity of the triarchic psychopathy model has yet to be evaluated in the Swedish forensic psychiatric context. We examined associations between the three phenotypic constructs of the triarchic model of psychopathy (i.e., boldness, meanness, disinhibition), self-assessed empathy and anxiety, and clinical variables in 91 individuals undergoing pretrial forensic psychiatric evaluation in Sweden. Participants completed the Triarchic Psychopathy Measure (TriPM) and self-report measures of empathy and anxiety. Clinical variables, including psychiatric diagnoses and criminal behavior, were collected from the forensic psychiatric evaluations (FPE). All three subscales of the TriPM displayed significant and predominantly anticipated correlations with empathy and trait anxiety measures. TriPM Disinhibition was the only subscale with significant associations with the clinical variables collected from the FPEs. The results provide evidence for the reliability and construct validity of the Swedish translation of the TriPM in a pretrial forensic setting.

Aggressive and psychopathic traits are linked to the acquisition of stable but imprecise hostile expectations

Individuals with hostile expectations (HEX) anticipate harm from seemingly neutral or ambiguous stimuli. However, it is unclear how HEX are acquired, and whether specific components of HEX learning can predict antisocial thought, conduct, and personality. In an online sample of healthy young individuals (n = 256, 69% women), we administered a virtual shooting task and applied computational modelling of behaviour to investigate HEX learning and its constellation of correlates. HEX acquisition was best explained by a hierarchical reinforcement learning mechanism. Crucially, we found that individuals with relatively higher self-reported aggressiveness and psychopathy developed stronger and less accurate hostile beliefs as well as larger prediction errors. Moreover, aggressive and psychopathic traits were associated with more temporally stable hostility representations. Our study thus shows that aggressiveness and psychopathy are linked with the acquisition of robust yet imprecise hostile beliefs through reinforcement learning.

Trauma-related disorders and the bodily self: current perspectives and future directions

Trauma-related disorders are debilitating psychiatric conditions that influence people who have directly or indirectly witnessed adversities. Dramatic brain/body transformations and altered person's relationship with self, others, and the world occur when experiencing multiple types of traumas. In turn, these unfortunate modifications may contribute to predisposition to trauma-related vulnerability conditions, such as externalizing (aggression, delinquency, and conduct disorders) problems. This mini-review analyzes the relations between traumatic experiences (encoded as implicit and embodied procedural memories) and bodily self, sense of safety for the own body, and relationship with others, also in the presence of externalizing conducts. Furthermore, an emerging research area is also considered, highlighting principles and techniques of body-oriented and sensorimotor therapies designed to remodel bodily self-aspects in the presence of trauma, discussing their potential application with individuals showing externalizing problems.
