Light and dark trait subtypes of human personality – A multi-study person-centered approach

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). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985-992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9% White, 20.1% Black, 3.6% Hispanic, and 5.4% other) of adolescents (modal age = 17) in a military style residential facility (N = 409; Males = 80.6%). As hypothesized, a four-class solution was best, consistent with adult psychopathy subtyping research (Hare et al. in Handbook of Psychopathy 39-79, 2018; Roy et al. in Pers Disord: Theory Res Treat, in press). The PSCD subtype profiles were uniform across sex and race/ethnicity. Adolescents evincing a psychopathic trait propensity profile (elevated on all four PSCD domains) displayed the greatest number of arrests and higher overall externalizing psychopathology, compared to the other three latent classes, as well as higher internalizing psychopathology compared to adolescents with general delinquency. The PSCD provides a sound measure of psychopathic trait propensities in youth and our results offer investigators and clinicians a means for understanding person-centered psychopathic traits versus antisocial profiles among at-risk adolescents. Taken together, the current results may offer a viable approach for examining specific treatment targets based on PSCD subtype profiles.

Psychometric Validation and Environmental Psychological Correlates of the Light Triad Traits

Abstract. The Light Triad Scale (LTS) measures the concept of the Light Triad, which was conceptualized as personality traits that reflect a person’s loving and beneficent orientation toward others, consisting of Faith in Humanity, Humanism, and Kantianism. As a novel construct, the Light Triad has yet to establish its structural validity in non-Western countries and needs to demonstrate its association with environmental psychology constructs. This study aims to: (1) examine the structural and criterion validity of the LTS in the Philippines and (2) determine the influence of the Light Triad on environmental concerns and green purchase intentions. Data were collected through an online survey completed by 447 Filipino adolescents. Comparing three models (i.e., one-factor, two-factor, and intercorrelated three-factor models), the present findings corroborated the original model which proposed an intercorrelated three-factor model of the LTS. The LTS demonstrated criterion validity by establishing correlations with relevant measures of environmental psychological constructs. Additionally, path analysis showed that Humanism and Kantianism predicted green purchase intentions via an increase in environmental concern. Measurement and conceptual strengths, future directions, and limitations are discussed.

Good Personality and Subjective Well-Being: Presence of Meaning in Life and Perceived Social Support as Mediators

BACKGROUND

Good personality is a positive moral personality in the context of Chinese Confucianism. Based on a social-cognitive model of normative well-being, we propose that good personality positively predicts subjective well-being, mediated by the perceived social support and presence of meaning in life in the context of Chinese culture.

METHODS

In this cross-sectional study, there were 665 Chinese adults (134 males and 531 females) who participated in the Good Personality Questionnaire, Multi-Dimensional Scale of Perceived Social Support, Presence of Meaning in Life Questionnaire, Positive and Negative Affect Scale, and Satisfaction with Life Scale.

RESULTS

Good personality was positively associated with subjective well-being (SWB). Both the presence of meaning in life and perceived social support independently mediated the link between good personality and subjective well-being (SWB), and in Chinese adults, perceived social support has a greater mediating effect than the presence of meaning in life.

CONCLUSION

These findings illustrate that the presence of meaning in life and perceived social support mediate the relationship between good personality and subjective well-being in the context of Chinese culture, which supports the model of normative well-being and can provide more targeted intervention guidance for research on promoting well-being in the Chinese context.

The tangled webs we wreak: Examining the structure of aggressive personality using psychometric networks

OBJECTIVE

Trait aggression is a prominent construct in the psychological literature, yet little work has sought to situate trait aggression among broader frameworks of personality. Initial evidence suggests that trait aggression may be best couched within the nomological network of the Five-Factor Model (FFM). The current work sought to locate the most appropriate home for trait aggression among the FFM.

METHOD

We applied a preregistered regimen of psychometric network analyses to three datasets (combined N = 2927) that contained self-reports of trait aggression and the FFM traits.

RESULTS

Trait aggression was highly central in the factor-level networks, which contained associations consistent with the conceptualization of this construct as a lower-order component of low agreeableness. The facet-level networks revealed that the behavioral facets of trait aggression reflected low agreeableness, but that the anger and hostility facets reflected high neuroticism. The item-level network suggested that the intent to initiate aggressive encounters was the primary bridge that empirically linked trait aggression to agreeableness.

CONCLUSIONS

Our results indicate that trait aggression is primarily a lower-order facet of agreeableness, advance our understanding of trait aggression, integrate it with broader frameworks of personality, and suggest future directions to refine this complex dispositional tendency.

Light and Dark core of personality and the adherence to COVID-19 containment measures: The roles of motivation and trust in government

The present study investigated the relationship between the Light and Dark Core of personality and self-reported adherence to COVID-19 containment measures. A gender-balanced representative sample of 600 Slovaks participated in the study. We formulated a mediation model, hypothesising that the relationship between Light and Dark Core and self-reported adherence is mediated by the motivation to comply with the measures. The results of structural equation modelling showed that self-reported adherence was positively related to the Light Core and this relationship was also mediated by motivation. The Dark Core, in turn, showed a negative relationship with the adherence, while no mediation was found. Importantly, the findings of both Light and Dark Core models remained robust after including trust in government. The present study contributes to theory by providing first results corroborating the existence of Light Core of personality. The findings of this study can also help to better shape the communications about containment measures to address both individuals with high levels of benevolent and malevolent 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.
