There is an ongoing debate about anxiety deficits in psychopathy and their possible impact on individual behavior. Data on actual anxiety- and threat-related behavior associated with psychopathy is still limited. We performed a mixed reality study using the elevated plus-maze (EPM) in a non-clinical sample (N = 160) to test anxiety-related behavior in relation to psychopathic personality traits measured through the Brief Questionnaire of Psychopathic Personality Traits (FPP). The psychopathy sum score correlated significantly with all measures of anxiety-related behavior on the EPM. Sensation seeking, but not general levels of acrophobia was moreover associated with psychopathic traits. Multivariate analyses revealed that the subscales Fearlessness and Lack of Empathy of the FPP predicted anxious behavior. Our findings are the first to demonstrate the relationship between psychopathic traits and actual behavior in an anxiety-inducing environment. This supports the low-anxiety hypothesis in psychopathy research. Implications for potentially harmful or risky behavior are discussed.

The Traffic Locus of Control scale (T-LOC) serves as a measure of drivers' personality attributes, providing insights into their perceptions of potential causes of road traffic crashes (RTCs). This study meticulously evaluated the psychometric properties of the Arabic version of T-LOC (T-LOC-A) among Lebanese drivers. Additionally, the study aimed to explore associations between the T-LOC scale and various driving variables, including driver behavior, accident involvement, and traffic offenses. A cross-sectional study was conducted among Lebanese drivers using a face-to-face approach. The validation of the Arabic version of T-LOC (T-LOC-A) occurred through a two-stage process: translating and culturally adapting T-LOC in the first stage, and testing its psychometric properties in the second stage. Data were collected using a comprehensive self-reported questionnaire in Arabic, covering demographic and travel-related variables, risk involvement, and measures such as the Driver Behavior Questionnaire (DBQ) and T-LOC. Exploratory factor analysis and confirmatory factor analysis were performed to scrutinize the factorial structure of T-LOC. Pearson correlation and chi-square tests were used for continuous and categorical variables, respectively. Two logistic regression analyses were executed to probe associations between T-LOC and involvement in road traffic crashes (RTCs) and T-LOC subscales with the occurrence of traffic offenses. The study included 568 drivers, predominantly male (69%) and aged between 30 and 49 years (42.1%). The findings revealed that T-LOC-A exhibited robust psychometric properties, with excellent reliabilities (α = 0.85) and adherence to the original four-factor structure, encompassing self (α = 0.88), other drivers (α = 0.91), vehicle/environment (α = 0.86), and fate (α = 0.66). The multidimensional structure was statistically supported by favorable fit indices. Gender differences revealed men attributing responsibility to other drivers, while women leaned towards fate and luck beliefs. Regarding driver behavior, the "other drivers" and self-dimensions of T-LOC-A correlated positively with aggressive violations. The fate dimension showed positive associations with aggressive violations and lapses. The "other drivers" subscale correlated positively with errors, and the vehicle/environment subscale with lapses. External T-LOC factors were positively associated with accident involvement, while the "LOC self" factor emerged as a protective element. In terms of traffic offenses, "LOC fate" displayed a positive association, while the "LOC self" factor showed a protective effect. In conclusion, the Arabic T-LOC is a reliable and valuable instrument, suggesting potential improvements in driving safety by addressing drivers' locus of control perceptions.

OBJECTIVES
Individuals vary in their levels of Desire for Aesthetics, ranging from superficial interest to profound immersion. However, there is currently a lack of measurement tools available to assess Desire for Aesthetics across various domains within German-speaking populations. Addressing this gap, the present study aimed to develop the Desire for Aesthetics Scale in German (DFAS-G) and evaluate its psychometric properties to comprehensively assess aesthetic preferences and inclinations.
METHODS
We conducted three consecutive studies and collected three samples of students and university employees. In Study 1 (N = 317), we selected a translated item pool using the forward-backward translation method, conducted cultural adaptation of the items, and assessed the scale's factor structure through an exploratory factor analysis. In Study 2 (N = 304), we revised and cross-validated the scale using confirmatory factor analysis and examined the final 37-item DFAS-G for reliability and validity. In Study 3 (N = 300), we further examined the scales construct validity and assessed retest reliability 291 days after initial testing.
RESULTS
The factor analysis conducted in Study 1 resulted in a four-factor solution representing the Desire for Aesthetics in four domains: Visual Arts, Individuals, Music, and Habitat. We found good internal consistency for the global scale (Cronbach's alpha = 0.87) and all subscales (0.74 to 0.82). We also found construct validity with Art Interest and facets of the Big Five personality trait Openness and provided first evidence of criterion validity and incremental validity of the DFAS-G global score toward Aesthetic Perception and Visual Arts toward Art Interest in Study 2. We further found evidence of convergent validity with the Openness facet Aesthetics, discriminant validity with the facet Values, and high test-retest reliability (0.85 to 1.00) in Study 3.
CONCLUSIONS
The present article provides a scale for measuring DfA in German-speaking populations and first steps of its validation. The DFAS-G extends the repertoire of options for psychological research on individual differences in aesthetics appreciation. Follow-up studies could provide further evidence of the subscale's validity and equivalence to the original scale.

Convergence of the dimensional assessment of personality pathology (DAPP-BQ) and the five-factor personality inventory for the international classification of diseases 11th edition (FFiCD) in the context of the five-factor model and personality disorders.
The current manuscript presents the convergence of the Dimensional Assessment of Personality Pathology (DAPP-BQ), using its short form the DAPP-90, and the Five-Factor Personality Inventory for International Classification of Diseases (ICD-11), the FFiCD, in the context of the five-factor personality model and the categorical approach of personality disorders (PDs). The current manuscript compares the predictive validity of both the FFiCD and the DAPP-90 regarding personality disorder scales and clusters. Results demonstrate a very high and meaningful convergence between the DAPP-90 and the FFiCD personality pathology models and a strong alignment with the FFM. The DAPP-90 and the FFiCD also present an almost identical predictive power of PDs. The DAPP-90 accounts for between 18% and 47%, and the FFiCD between 21% and 47% of PDs adjusted variance. It is concluded that both DAPP-90 and FFiCD questionnaires measure strongly similar pathological personality traits that could be described within the frame of the FFM. Additionally, both questionnaires predict a very similar percentage of the variance of personality disorders.

Evidence links immune system alterations to major psychiatric disorders. The few previous studies on personality traits or personality disorders (PDs) indicate that immunometabolic dysregulation may be prevalent in this population. This study aimed to investigate relationships between personality traits, PDs, and immunometabolic markers in peripheral blood. We hypothesized that neuroticism would be correlated with elevated leptin. Participants were recruited as young adults seeking care for general psychiatric disorders. They responded to a personality inventory and were assessed for PDs, and reevaluated again at a 12 years follow-up. Blood samples were collected at the follow-up and analyzed for 29 immunometabolic markers. A positive correlation was found between the personality trait neuroticism and leptin (ρ = 0.31, p = 0.02). An exploratory analysis also revealed a positive correlation between brain-derived neurotrophic factor (ρ = 0.36, p < 0.01) and neuroticism. These findings remained after adjusting for other variables in general linear models. There were no relationships between PDs and any immunometabolic markers. Results both confirm previous findings of correlations between the immunometabolic system and personality traits and suggest directions for future research.

Augmenting complex and dynamic performance through mindfulness-based cognitive training: An evaluation of training adherence, trait mindfulness, personality and resting-state EEG.
Human performance applications of mindfulness-based training have demonstrated its utility in enhancing cognitive functioning. Previous studies have illustrated how these interventions can improve performance on traditional cognitive tests, however, little investigation has explored the extent to which mindfulness-based training can optimise performance in more dynamic and complex contexts. Further, from a neuroscientific perspective, the underlying mechanisms responsible for performance enhancements remain largely undescribed. With this in mind, the following study aimed to investigate how a short-term mindfulness intervention (one week) augments performance on a dynamic and complex task (target motion analyst task; TMA) in young, healthy adults (n = 40, age range = 18-38). Linear mixed effect modelling revealed that increased adherence to the web-based mindfulness-based training regime (ranging from 0-21 sessions) was associated with improved performance in the second testing session of the TMA task, controlling for baseline performance. Analyses of resting-state electroencephalographic (EEG) metrics demonstrated no change across testing sessions. Investigations of additional individual factors demonstrated that enhancements associated with training adherence remained relatively consistent across varying levels of participants' resting-state EEG metrics, personality measures (i.e., trait mindfulness, neuroticism, conscientiousness), self-reported enjoyment and timing of intervention adherence. Our results thus indicate that mindfulness-based cognitive training leads to performance enhancements in distantly related tasks, irrespective of several individual differences. We also revealed nuances in the magnitude of cognitive enhancements contingent on the timing of adherence, regardless of total volume of training. Overall, our findings suggest that mindfulness-based training could be used in a myriad of settings to elicit transferable performance enhancements.

OBJECTIVES
Self-efficacy for illness management is increasingly recognized as important for outcomes in cancer. We examined whether The Big Five personality dimensions were associated with self-efficacy for illness management and hypothesized that patients who were less neurotic and more conscientious would have better self-efficacy.
METHODS
Adults with cancer completed a cross-sectional survey that included the Mini-International Personality Item Pool (IPIP) and three subscales of the Patient-Reported Outcomes Measurement Information System (PROMIS) Self-Efficacy for Chronic Conditions: managing emotions, managing symptoms, and managing treatment and medication. Linear regressions were used to test the hypotheses, while controlling for covariates.
RESULTS
The personality and PROMIS self-efficacy measures demonstrated good evidence of reliability (median Cronbach's alpha = .78, range of .69-.92) and validity (intercorrelations). As hypothesized, patients who were less neurotic or more conscientious had higher levels of illness self-efficacy overall and on each of the three subscales (all s < .001). Openness was associated with better self-management of symptoms ( = .013) and emotions ( = .040). Extraversion was associated with better self-management of emotions ( = .024).
CONCLUSIONS
Personality plays a vital role in illness self-efficacy for patients with cancer.
PRACTICE IMPLICATIONS
As a part of multidisciplinary care teams, psychosocial experts can use these findings to help patients better manage their illness.

Background Workplace bullying is persistent aggressive behavior, including verbal or physical abuse, exhibited in a working environment. The impact of workplace bullying in any industry leads to negative outcomes in multiple dimensions, such as issues with mental health, problems with physical health, and a reduction in productivity in the workplace. This study aims to measure the relationship between personality traits and workplace bullying victims. Moreover, it explores how personality traits predict being a victim of workplace bullying. Methodology A cross-sectional study was conducted among 625 participants from various regions of Saudi Arabia. Data was collected using a self-administered survey, which included sociodemographic questions, the Negative Acts Questionnaire-Revised (NAQ-R) for bullying assessment, and the Big Five Personality Inventory (BFI-10) for personality trait assessment. The statistical analysis encompassed descriptive statistics and inferential tests such as the correlation test, Mann-Whitney U test, and Kruskal-Wallis test. These analyses were conducted using the SPSS software version 27.0.1 (IBM Corp., Armonk, NY, USA). Results Personal-related bullying was more prevalent compared to work-related bullying, particularly "facing disregard of opinion" was the most frequent type of bullying. Moreover, conscientiousness, agreeableness, and openness to experience were demonstrated as major self-perceived personality traits among participants. Some sociodemographic factors were reported to be significantly associated with both bullying and personality trait scores. Personality traits such as conscientiousness, agreeableness, and extraversion were adversely correlated while openness to experience and neuroticism were positively correlated with bullying. Conclusions Our study illustrates the current prevalence of workplace bullying in Saudi Arabia and its impact on participants' mental health and productivity. We identified a significant correlation between self-perceived personality traits and the risk of experiencing workplace bullying. These findings offer valuable insights for policymakers, enabling them to develop targeted interventions to reduce bullying within work settings in Saudi Arabia.

Journal of Affective Disorders Aug 2024Temperament and character are useful in risk assessment and therapy of individuals in the anxiety-depression spectrum but understudied in South Korea. (Review)
Review
BACKGROUND
Temperament and character are useful in risk assessment and therapy of individuals in the anxiety-depression spectrum but understudied in South Korea.
OBJECTIVE
The study aimed to identify the temperament and character features associated with anxiety and/or depression in individuals with clinical disorders and in the general population.
METHODS
A representative sample of 1384 Korean adults over 18 years old (58 % female) were assessed with the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Temperament and Character Inventory (TCI). Multivariate analyses, including structural equation modeling and complex systems analysis, evaluated how personality influenced risk and resilience for anxiety and/or depression.
RESULTS
The three groups with anxiety and/or depression were strongly distinguished by temperament and character: (i) In AD (n = 58), Harm Avoidance and Reward Dependence were higher than in DD, and Self-directedness was higher than in AD+DD; (ii) In DD (n = 90), Persistence, Self-Directedness and Cooperativeness were higher than in AD+DD; and (iii) In AD+DD (n = 101), Harm Avoidance was highest and Persistence and Self-directedness were lowest (i.e., they were lowest in Resilience). Structural equation models confirmed these risk relations with strong character development reducing the adverse effects of emotional hyperreactivity from extreme temperaments.
LIMITATIONS
Self-reports were measured only at one point in time, requiring collateral experimental data to support causal interpretation.
CONCLUSIONS
Interactions of temperament and character are strongly predictive of risk and resilience to anxiety and/or depression by regulating both positive and negative affect. Character mediates the adverse effects of extreme temperaments on affect.

BACKGROUND
Resilience plays a crucial role in mental health promotion and prevention, and was shown to be more represented in individuals who exhibit high levels of extraversion, openness, agreeableness, and conscientiousness. However, there is a lack of studies that comprehensively investigate the association between personality traits and resilience in Lebanon and Arab countries more broadly. The purpose of the present study was to complement the literature by investigating the direct and indirect effects between the five personality traits and resilience among a sample of Lebanese adults through the intermediary role of posttraumatic growth.
METHODOLOGY
A cross-sectional study was carried out between May and July 2022, and enrolled 387 participants, all aged above 18 years old and recruited from all Lebanon governorates. The questionnaire used included socio-demographic questions, and the following scales: Connor-Davidson Resilience Scale (CD-RISC) to assess resilience, post traumatic growth (PTG), and Big Five Inventory (BFI-2). The SPSS software v.25 was used for the statistical analysis.
RESULTS
Post-traumatic growth mediated the association between extraversion / agreeableness / conscientiousness and resilience. Higher extraversion / agreeableness / conscientiousness was significantly associated with more post-traumatic growth. Higher post-traumatic growth was significantly associated with more resilience. Extraversion, but not agreeableness and conscientiousness, was significantly and directly associated with more resilience.
CONCLUSION
Findings suggest that fostering PTG in individuals who experience adversity can help promote their resilience. Hence, it could be beneficial to design and apply programs aiming at supporting PTG among people who experience stressful and traumatizing situations, to consequently help them increase their sense of resilience.
