Differences and Similarities in how Psychopathic Traits Predict Attachment Insecurity in Females and Males

Association Between Traumatic Brain Injury and Psychopathic Traits Among Justice-Involved Adolescents

Traumatic brain injury (TBI) is a global public health problem and is highly prevalent among justice-involved populations. Pediatric TBI is linked with long-term negative outcomes and is correlated with substance use, criminal behavior, psychiatric disorders, and disruptions in neurocognition. These same TBI correlates are evident among youth with psychopathic traits. Given ongoing neurobiological and social development in adolescence, understanding the link between psychopathic traits and TBI in justice-involved youth is critical. A sample of 263 male adolescents were recruited from a maximum-security juvenile justice facility. Using a structural equation modeling (SEM) framework, measurement invariance of psychopathic traits (TBI ±) was tested, and psychopathy scores were accounted for in terms of TBI variables (severity, age of first TBI, total number), participant's age, IQ, substance use, and internalizing psychopathology. There was evidence of strong invariance across TBI status and those with TBI had higher affective and impulsive lifestyle psychopathic traits than adolescents without TBI. The SEM indicated that TBI severity was associated with lower IQ scores, which in turn were associated with increased lifestyle/antisocial (Factor 2) psychopathic traits. Total number of TBIs was associated with higher substance use, which was associated with both increased interpersonal/affective (Factor 1) and Factor 2 psychopathic traits. These TBI variables also had indirect associations with psychopathic traits through IQ and substance use. The findings indicate that TBI is associated with psychopathic traits and suggest that disturbances in cognition and substance use may be treatment targets for youth with TBI and psychopathic traits.

Primary and Secondary Psychopathic Traits: Investigating the Role of Attachment and Experiences of Shame

Primary and secondary psychopathic traits have been documented in the general population and previous research has shown their link to adult insecure attachment and shame. However, there has been a gap in the literature examining the specific role of attachment avoidance and anxiety, and experiences of shame in the expression of these psychopathic traits. This study aimed to explore the associations between the attachment dimensions of anxiety and avoidance, in addition to characterological, behavioral and body shame with primary and secondary psychopathic traits. A non-clinical sample of 293 adults (M age= 30.77, SD = 12.64; 34% males) was recruited and completed an online battery of questionnaires. Hierarchical regression analyses indicated that demographic variables (age and gender) explained the largest variance for primary psychopathic traits, while the attachment dimensions (anxiety and avoidance) explaining the largest variance for secondary psychopathic traits. Characterological shame had a direct and indirect effect on both primary and secondary psychopathic traits. The findings highlight the need to examine psychopathic traits in community samples as a multidimensional construct, with a particular focus on also assessing attachment dimensions and shame subtypes.

Traumatic Brain Injury and Psychopathic Traits in Justice-Involved Adult Women

Studies have documented associations between traumatic brain injury (TBI) and mental disorders. The relationship between psychopathic personality and TBI remains poorly understood, though both are associated with similar characteristics (e.g., low empathy, aggression, disturbances in social/moral behavior). Yet, it is not clear whether assessment of psychopathic features is influenced by presence versus absence of TBI, and which aspects of TBI may be associated with psychopathic traits. This study examined the psychopathy-TBI association in justice-involved women (N = 341) with structural equation modeling. We tested if measurement invariance of psychopathic traits was evident among those with versus without TBI and which TBI variables (number, severity, age at first TBI) predicted psychopathic features in conjunction with symptoms of psychopathology, IQ, and age. Results provided evidence of measurement invariance, and more women with TBI, compared to those without, met criteria for psychopathy. Younger age of TBI and TBI severity predicted interpersonal-affective psychopathic features.

The relationship between attachment styles, psychopathology and quality of social interaction: A study on a clinical sample

The aim of this study is to examine the differences between four attachment styles in relation to symptoms of psychopathology and the quality of social interaction, as well as to determine the role of attachment and psychopathology in predicting positive and negative social exchange. A total of 57 participants from the neuropsychiatric department of the Service for Specialist-Consultative Health Activities of the Health Centre in Novi Sad took part in the research. Respondents were mostly female (61%), aged 17 to 68 (M=40.13, SD=12.35). The Relationship Questionnaire (RQ) was used for attachment styles assessment. Psychopathological symptoms were measured using the Cornell Index (CI-N4), and the quality of social relationships was evaluated via the Network of Relationship Inventory (NRI). The highest rate of symptoms was detected in subjects with a preoccupied style, followed by those whose style was identified as fearful. The same two styles showed the least positive social exchange. Statistically significant differences on most scales from CI-N4 were found mainly between the secure and preoccupied subjects, while subjects with the avoidant pattern did not demonstrate significant differences in psychopathology and social functioning compared to secure participants. Secure affective attachment and low aggressive-antisocial indicators (impulsiveness, aggression, and paranoia) were the most important predictors of positive social exchange. Understanding psychopathological manifestations of different insecure attachment styles can contribute to the efficiency of psychodiagnostic and psychotherapeutic processes. Furthermore, the fact that insecure attachment and aggressive-antisocial factor predominantly compromise positive social interaction can facilitate goal setting during psychological treatment within the clinical spectrum.

Are you laughing with me or at me? Psychopathic traits and the ability to distinguish between affiliation and dominance laughter cues

OBJECTIVE

Laughter conveys important information that supports social communication and bonding. Research suggests that unique acoustic properties distinguish laughter that promotes affiliation from laughter that conveys dominance, but little is known about potential individual differences in laughter interpretation or contagion based on these specified social functions of laughter. Psychopathy is associated with both affiliative deficits (e.g., lack of empathy and impaired social bonding) and behaviors that assert social dominance (e.g., manipulativeness). Thus, relationships between psychopathic traits and impaired laughter interpretation or contagion could give insight into etiological pathways to psychopathy.

METHOD

In two studies conducted with four independent samples (total N = 770), participants categorized laughter clips that varied in the degree of affiliation or dominance conveyed.

RESULTS

Participants overall drew rich and accurate social inferences from dominant and affiliative laughter and modulated their interest in joining in with laughter based on the type and degree of affiliation and dominance conveyed. However, individuals higher in psychopathic traits failed to distinguish between laughter types and did not modulate their level of engagement based on laughter features.

CONCLUSIONS

The results suggest a potential mechanism that underlies the broader social difficulties associated with psychopathic traits.

Adult attachment and psychopathic traits: Investigating the role of gender, maternal and paternal factors

Individuals with psychopathic traits have been identified to display insecure attachment. However, it is not clear which attachment dimension contributes more to high psychopathic traits, and more specifically to callous-unemotional (CU) traits, which parental relationship is more influential and if this differs across gender. This study examined the associations of adult attachment dimensions (avoidance and anxiety) and parental factors (regard, responsibility and control) with CU traits (N = 1149) using Hierarchical Linear Regression. The relationship with both parents was assessed separately to identify their unique contribution to CU traits in males and females respectively. The avoidant attachment positively predicted while the anxiety attachment dimension negatively predicted CU traits and this was the case for both male and female participants. Interestingly, maternal regard was a negative predictor of CU traits in males only, whereas paternal responsibility arose as a positive predictor of CU traits in females only. Attachment dimensions explained the largest variance in both males and females. Findings point to the importance of attachment dimensions contributing to CU traits even in an adult sample. Parental variables were less influential on CU traits compared to attachment related variables and findings suggest that there are differences between males and females. These findings have important implications for gender differentiated attachment based interventions for individuals with CU traits.

Examining the Short Dark Tetrad (SD4) Across Models, Correlates, and Gender

To date, no studies have examined a range of structural models of the interpersonally aversive traits tapped by the Short Dark Tetrad (SD4; narcissism, Machiavellianism, psychopathy, sadism), in conjunction with their measurement invariance (males vs. females) and how the models each predict external correlates. Using a large sample of young adults (N = 3,975), four latent variable models were compared in terms of fit, measurement invariance, and prediction of intrapersonal and interpersonal functioning. The models tested were as follows: (Model A) confirmatory factor analytic, (Model B) bifactor, (Model C) exploratory structural equation model, and (Model D) a reduced-item confirmatory factor analytic that maximized item information. All models accounted for item covariance with good precision, although differed in incremental fit. Strong invariance held for all models, and each accounted similarly for the external correlates, highlighting differential predictive effects of the SD4 factors. The results provide support for four theoretically distinct but overlapping dark personality domains.

Structural equation modeling of the associations between amygdala activation, personality, and internalizing, externalizing symptoms of psychopathology

There is an expanding literature on the theoretical and empirical connections between personality and psychopathology, and their shared neurobiological correlates. Recent cybernetic theories of personality and psychopathology, as well as affective neuroscience theory, provide grounding for understanding neurobiological-personality-psychopathology (NPP) associations. With the emergence of large sample datasets (e.g., Human Connectome Project) advanced quantitative modeling can be used to rigorously test dynamic statistical representations of NPP connections. Also, research suggests that these connections are influenced by sex, and large samples provide the opportunity to examine how NPP associations might be moderated by sex. The current study used a large sample from the Duke Neurogenetics Study (DNS) to examine how amygdala activation to facial expressions was linked with self-report of personality traits and clinical interviews of internalizing and externalizing symptoms of psychopathology. Structural equation modeling results revealed direct associations of amygdala activation with personality trait expression, as well as indirect associations (though personality) with symptoms of psychopathology. Moreover, the NPP links were moderated by sex. The current results are in line with research that identifies a broader role played by the amygdala in personality and provide potential insights for continued research in personality neuroscience and recent theories on the neurobiology of personality.
