Investigating the relationship between personality traits of hardiness and perfectionism with stress and psychosomatic symptoms: a cross-sectional study among nurses in Iran.

BACKGROUND: Medical and health sector employees are always exposed to physical and psychological risk factors, which affects their personal, social and professional performance. It's important to explores the intricate interplay between personality traits, stress levels, and psychosomatic symptoms among nurses as one of the most sensitive jobs in society. Therefore, the present study aimed to investigating the relationship between the personality traits of hardiness and perfectionism with stress and psychosomatic symptoms among nurses. METHODS: This cross-sectional study was conducted among 340 nurses in Mazandaran, Iran in 2022-2023. The instruments utilized to collect data included four questionnaires, namely Cubasa Hardiness Questionnaire, Tehran Multidimensional Perfectionism Questionnaire, Nursing Stress Questionnaire and Takata and Sakata Psychosomatic Questionnaire. The structural equations modeling was used for path analysis. All analyzes were done using SPSS V.25.0 and AMOS V.24.0 software. RESULTS: The results of the present study revealed that the prevalence of psychosomatic symptoms and stress in nurses was high, and all path coefficients were significant, except for the paths of commitment to stress, challenge to psychosomatic symptoms, self-orientation to psychosomatic symptoms, and community-orientation to psychosomatic symptoms. The results showed that in the final model, the highest coefficient (0.807) is assigned to the other-oriented perfectionism path to psychosomatic symptoms. The weakest coefficient (-0.276) is related to the path of the hardiness component of the challenge to stress. The current research examined the fitting of the proposed model and the suitability of the proposed model was confirmed. CONCLUSION: The results of the present study revealed that psychological factors such as personality traits of hardiness, and perfectionism are among the important and influencing parameters on occupational stress, and psychosomatic symptoms and as a result the efficiency and effectiveness of nurses in working environments. Therefore, it is absolutely necessary to implement mitigating and control measures to reduce the mentioned risk factors among nurses in medical settings.

[Sir William Osler: facets of personality].

William Osler is one of the most honored and influential physicians in the English medicine late 19th early 20th century, who has made a great contribution on development of medical science and it's teaching. The scope of his multifaceted personality goes far beyond the characteristics of an outstanding doctor and scientist. The historical essay presents various aspects of the Osler's personality, highlighting his uniqueness as a doctor, teacher and philosopher.

Impulsivity is a stable, measurable, and predictive psychological trait.

Impulsivity is a personality construct frequently employed to explain and predict important human behaviors. Major inconsistencies in its definition and measurement, however, have led some researchers to call for an outright rejection of impulsivity as a psychological construct. We address this highly unsatisfactory state with a large-scale, preregistered study (N = 1,676) in which each participant completed 48 measures of impulsivity derived from 10 self-report scales and 10 behavioral tasks and reported frequencies of seven impulsivity-related behaviors (e.g., impulsive buying and social media usage); a subsample (N = 196) then completed a retest session 3 mo later. We found that correlations between self-report measures were substantially higher than those between behavioral tasks and between self-report measures and behavioral tasks. Bifactor analysis of these measures exacted one general factor of impulsivity I, akin to the general intelligence factor g, and six specific factors. Factor I was related mainly to self-report measures, had high test-retest reliability, and could predict impulsivity-related behaviors better than existing measures. We further developed a scale named the adjustable impulsivity scale (AIMS) to measure I. AIMS possesses excellent psychometric properties that are largely retained in shorter versions and could predict impulsivity-related behaviors equally well as I. These findings collectively support impulsivity as a stable, measurable, and predictive trait, indicating that it may be too early to reject it as a valid and useful psychological construct. The bifactorial structure of impulsivity and AIMS, meanwhile, significantly advance the conceptualization and measurement of construct impulsivity.

The evolution of olfactory sensitivity, preferences, and behavioral responses in Mexican cavefish is influenced by fish personality.

Animals are adapted to their natural habitats and lifestyles. Their brains perceive the external world via their sensory systems, compute information together with that of internal states and autonomous activity, and generate appropriate behavioral outputs. However, how do these processes evolve across evolution? Here, focusing on the sense of olfaction, we have studied the evolution in olfactory sensitivity, preferences, and behavioral responses to six different food-related amino acid odors in the two eco-morphs of the fish Astyanax mexicanus. To this end, we have developed a high-throughput behavioral setup and pipeline of quantitative and qualitative behavior analysis, and we have tested 489 six-week-old Astyanax larvae. The blind, dark-adapted morphs of the species showed markedly distinct basal swimming patterns and behavioral responses to odors, higher olfactory sensitivity, and a strong preference for alanine, as compared to their river-dwelling eyed conspecifics. In addition, we discovered that fish have an individual 'swimming personality', and that this personality influences their capability to respond efficiently to odors and find the source. Importantly, the personality traits that favored significant responses to odors were different in surface fish and cavefish. Moreover, the responses displayed by second-generation cave × surface F2 hybrids suggested that olfactory-driven behavior and olfactory sensitivity is a quantitative genetic trait. Our findings show that olfactory processing has rapidly evolved in cavefish at several levels: detection threshold, odor preference, and foraging behavior strategy. Cavefish is therefore an outstanding model to understand the genetic, molecular, and neurophysiological basis of sensory specialization in response to environmental change.

Are lateralized and bold fish optimistic or pessimistic?

Cognitive bias is defined as the influence of emotions on cognitive processes. The concept of the cognitive judgement bias has its origins in human psychology but has been applied to animals over the past 2 decades. In this study we were interested in determining if laterality and personality traits, which are known to influence learning style, might also be correlated with a cognitive bias in the three-spined sticklebacks (Gasterosteus aculeatus). We used the judgement bias test with the go/no-go procedure where fish were first trained to discriminate between a black and white card and, after reaching a minimum learning criterion, tested their response to an ambiguous card (grey). Optimistic subjects were expected to have a high expectation of reward associated with an ambiguous stimulus, whereas pessimistic subjects a high expectation of non-reward. We used an emergence and a mirror test to quantify boldness and laterality, respectively. We hypothesised that male, bolder and more strongly lateralized fish would be more optimistic than female, shy and less strongly lateralised fish. We found that males and more strongly lateralized fish were more optimistic than females and less strongly lateralized fish. In addition, bold males were more optimistic than shy males as we predicted, but females showed the opposite pattern. Finally, fish trained on the black colour card learned the training task faster than those trained on a white card. Our results indicate that both laterality and personality traits are linked to animals' internal states (pessimistic or optimistic outlooks) which likely has broad implications for understanding animal behaviour particularly in a welfare context.

The leading role of personality in concerns about autonomous vehicles.

Development of autonomous vehicles (AVs) is growing in a rapid rate, however, the most dominant barriers in their adoption seem to be rather psychological than technical. The present online survey study aimed to investigate which demographical and personality dimensions predict attitudes towards AVs on a Hungarian sample (N = 328). Data was collected by convenience and snowball sampling. Three-level hierarchical regression models were applied: in the first level, demographical variables, then general personality traits and third, attitude-like personality factors were entered. We demonstrated that the predictive effect of age, gender and education disappeared when personality dimensions were included into the models. Importantly, more positive general attitudes towards technology and higher optimism regarding innovations predicted eagerness to adopt AVs. On the other hand, individuals with more negative attitudes and higher dependence on technology as well as those with lower level of Sensory Sensation Seeking and higher level of Conscientiousness were more concerned about AVs. Our results suggest that AV acceptance cannot be regarded as a one-dimensional construct and that certain personality traits might be stronger predictors of AV acceptance than demographical factors.

Prevalence of Self-reported Domestic Elder Abuse and Its Relation with Personality Traits of Older People and Their Family Caregivers.

BACKGROUND: Elder abuse (EA) is a serious public health issue recognized as a healthcare priority. Personality traits can influence social behaviors. This study aimed to determine the prevalence of self-reported domestic EA and its relationship with personality traits of older people and their family caregivers. METHODS: A cross-sectional study was conducted in 2022. The research population included older people living in the urban community of the Lorestan Province (in the western region of Iran) selected by multistage cluster sampling. In general, 998 older people and their family caregivers were sampled. The data collection tool was a three-part questionnaire: a. demographic characteristics of the older people, b. questionnaire on the incidence of elder abuse, and c. short version of the NEO Five-Factor Inventory-Revised (NEO-FFI-R) for measuring the personality traits of the older people or family caregivers. The statistical software used was Stata 14. RESULTS: The present study reported that the prevalence of EA at home was 37.78%. In the present study, older age, female gender, unmarried/single status, lower education, unemployment, and rented house characteristics were predictors of EA. High agreeableness, high extroversion, and low neuroticism reduce conflict and tension in older people with their relatives and family, which appear to be protective factors against EA. CONCLUSION: Policymakers and health experts should prepare training and screening programs to consider these factors so that older people exposed to EA can be identified more quickly and early interventions can be used to improve their health status and increase their quality of life.

Roles of negative emotions and personality traits in psoriasis vulgaris: A mendelian randomization study.

BACKGROUND: Many studies have indicated that negative emotions and personality traits are related to psoriasis, though few have provided causal evidence. METHODS: Our analysis utilized 15 genome-wide association study datasets to identify instrumental variables associated with negative emotions, personality traits and psoriasis vulgaris. Two-sample Mendelian randomization was conducted to identify the causal associations of negative emotions and personality traits with psoriasis vulgaris. To mitigate bias from multiple tests, we adjusted p-values using the Benjamini-Hochberg method. RESULTS: Our study revealed causal links between negative emotions and psoriasis vulgaris, including depressed affect, worry too long, feeling hurt, guilty feelings, mood swings, unenthusiasm, miserableness, fed-up feelings. However, there was no significant evidence of a causal relationship between feeling lonely and psoriasis vulgaris. Additionally, personality traits including neuroticism and openness to experience were found to have causal effects on psoriasis vulgaris. However, no significant evidence supported a causal relationship between agreeableness, conscientiousness, and extraversion with psoriasis vulgaris. CONCLUSION: Our findings suggest that experiencing negative emotions including depressed affect, worrying excessively, feeling hurt, guilty feelings, mood swings, lack of enthusiasm, miserableness and fed-up feelings may pose risks for psoriasis vulgaris. Additionally, neuroticism is associated with a risk of psoriasis vulgaris. Conversely, the openness trait may serve a protective role against psoriasis vulgaris.

The mediating effect of post-traumatic growth on the relationship between personality traits and resilience among a sample of Lebanese adults.

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.

The Chronic Time Pressure Inventory: further assessment of factorial structure and validity.

Background: Chronic time pressure represents a prevalent concern within modern society, and effective measurement is crucial for research advancement. The Chronic Time Pressure Inventory (CTPI) has thus far demonstrated adequate psychometric properties. However, only two studies have examined the measure and evidence of its validity is limited. Accordingly, the current investigation, via two independent studies, assessed the factorial composition and validity (convergent/discriminant) of the CTPI. Methods: Study 1 (N = 398) examined competing factorial models and validity in relation to the Big Five personality traits (Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness). Study 2 (N = 358) replicated the analysis of factor structure and assessed validity in comparison with five time perspectives (Past Negative, Present Fatalistic, Future, Past Positive, Present Hedonistic). Participants across both studies completed standardized self-report measures capturing the variables. Results: Comparison of confirmatory factor analysis (CFA) and exploratory structural equation modelling (ESEM) factor solutions indicated that an ESEM bifactor model provided the strongest data-model fit. This included a general chronic time pressure component alongside specific subfactors of Feeling Harried and Cognitive Awareness of Time Shortage. All scale items reflected the general factor; however, some items loaded weakly on the intended specific factor. The CTPI is thus a robust indicator of chronic time pressure but needs refinement as a measure of the specific factors. Convergent/discriminant validity analyses inferred that the CTPI captured chronic time pressure as a related, but distinct, construct to perceived stress, and evidenced a relationship with theoretically associated constructs (Big Five personality traits and time perspective). Overall, the CTPI is a sound measure of chronic time pressure and has the potential to further cohesive research efforts on the contribution of this construct to various life domains.

Dark Tetrad personality traits, paraphilic interests, and the role of impulsivity: an EEG-study using a Go/No-Go paradigm.

Maladaptive personality traits, such as 'dark personalities' are found to result in a diverse set of negative outcomes, including paraphilic interests and associated (illegal) behaviors. It is however unclear how these are exactly related, and if related, if then only those individuals higher on dark personality traits and higher impulsivity engage in paraphilic behaviors. In the current study, 50 participants were recruited to investigate the relationship between Dark Tetrad personality traits (i.e., narcissism, psychopathy, Machiavellianism and everyday sadism), paraphilic interests (arousal and behavior) and the moderating role of impulsivity. Personality and paraphilic interests were investigated through self-report questionnaires. Impulsivity was measured both through self-reported dysfunctional impulsivity and the P3 event related potential using electroencephalography during the Go/No-Go task (i.e. response inhibition). The results showed that there was a positive association between psychopathy, sadism and paraphilic interests. Whereas everyday sadism was associated with paraphilic (self-reported) arousal, psychopathy was associated with paraphilic behavior. Although P3 amplitude was not associated with paraphilic interests, self-reported dysfunctional impulsivity was associated with paraphilic behavior specifically. However, there was no moderating role of dysfunctional impulsivity and response inhibition (P3) in the relationship between psychopathy and paraphilic behavior. Findings indicate that the relation between specific dark personalities and paraphilic interests may be more complex than initially thought. Nevertheless, risk assessment and intervention approaches for paraphilia and related behavior both may benefit from incorporating Dark Tetrad and impulsivity measurements.

Predictive effects of organizational justice on job satisfaction in bus drivers: the moderating effects of role overload and proactive personality.

BACKGROUND: There have been few longitudinal studies on Chinese bus drivers and the individual differences in the relationships between organizational justice and job satisfaction. This study examined the organizational justice and job satisfaction in bus drivers and the individual differences in this relationship. METHODS: A two-wave longitudinal study design was employed. A first survey was conducted on 513 Chinese bus drivers in October 2021 that collected socio-demographic information and asked about their perceptions of organizational fairness. A second survey was conducted six months later that asked about role overload and job satisfaction and assessed their proactive personality type. An effect model was then used to explore the moderating effects of role overload and proactive personality type on the relationships between organizational justice and job satisfaction. RESULTS: Both procedural and interactive justice predicted the bus drivers' job satisfaction. Proactive personalities and role overload were found to enhance this relationship. CONCLUSIONS: Organizations could benefit from screening at the recruitment stage for drivers with highly proactive personalities. Relevant training for drivers with low proactive personalities could partially improve employee job satisfaction. When viewed from a Chinese collectivist cultural frame, role overload could reflect trust and a sense of belonging, which could enhance job satisfaction. Finally, to improve employee job satisfaction, organizations need to ensure procedural and interactive justice.

The big five factors as differential predictors of self-regulation, achievement emotions, coping and health behavior in undergraduate students.

BACKGROUND: The aim of this research was to analyze whether the personality factors included in the Big Five model differentially predict the self-regulation and affective states of university students and health. METHODS: A total of 637 students completed validated self-report questionnaires. Using an ex post facto design, we conducted linear regression and structural prediction analyses. RESULTS: The findings showed that model factors were differential predictors of both self-regulation and affective states. Self-regulation and affective states, in turn, jointly predict emotional performance while learning and even student health. These results allow us to understand, through a holistic predictive model, the differential predictive relationships of all the factors: conscientiousness and extraversion were predictors regulating positive emotionality and health; the openness to experience factor was non-regulating; nonregulating; and agreeableness and neuroticism were dysregulating, hence precursors of negative emotionality and poorer student health. CONCLUSIONS: These results are important because they allow us to infer implications for guidance and psychological health at university.

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.

Personality and psychopathological characteristics in functional movement disorders.

INTRODUCTION: Aim of the present study was to assess personality and psychopathological characteristics in patients with functional movement disorders (FMDs) compared to patients with other neurological disorders (OND). METHODS: In this cross-sectional study, patients affected by clinically established FMDs and OND who attended the Neurologic Unit of the University-Hospital "Policlinico-San Marco" of Catania from the 1st of December 2021 to the 1st of June 2023 were enrolled. Personality characteristics were assessed with the Rorschach test coded according to Exner's comprehensive system and the Structured Clinical Interview for DSM-5 (SCID-II). RESULTS: Thirty-one patients with FMDs (27 women; age 40.2±15.5 years; education 11.7±3.2 years; disease duration 2.3±2.5 years) and 24 patients affected by OND (18 women; age 35.8±16.3 years; education 11.9±2.9 years; disease duration 3.4±2.8 years) were enrolled. At the Rorschach, FMDs presented a significantly higher frequency of Popular (P) and sum of all Human content codes (SumH>5) responses and avoidant coping than OND. CONCLUSION: FMDs presented "conformity behaviors", excessive interest in others than usual a maladaptive avoidant style of coping and a difficulty in verbalizing emotional distress. These psychopathological characteristics may favor the occurrence of FMDs.

A controversial issue in adolescents: Is the effect of digital games on creative personality traits positive or negative?

AIM: This study aimed to determine the effect of digital games on the creativity of adolescents. METHODS: This study was designed as a cross-sectional study using simple random sampling following the STROBE checklist. It was conducted with 384 adolescents between January and June 2022. Data were collected using the Digital Game Addiction Scale for Children and the Creative Personality Traits Scale. RESULTS: The adolescents were at risk for digital game addiction and had moderate creativity levels. The adolescents who had a male sex, had mothers who received primary education, started playing digital games before the age of 6 years, were using the internet for >5 h a day, had no activity other than playing digital games, and preferred action, adventure, and fighting games had higher digital game addiction levels than the other adolescents. In addition, the male adolescents had higher creativity levels than the female adolescents. There was a significant negative relationship between digital game addiction and creative personality traits among the adolescents. Digital game addiction had a negative effect on creativity. CONCLUSIONS: Adolescents are at risk for digital game addiction and have moderate creativity levels. Digital game addiction negatively affects the development of creative personality traits. Interventions should be planned to prevent digital game addiction among adolescents, and adolescents should be guided to increase awareness of the effects of digital games on their creativity.

Are serious games an alternative to traditional personality questionnaires? Initial analysis of a gamified assessment.

Personality questionnaires stand as crucial instruments in personnel selection but their limitations turn the interest towards alternatives like game-related assessments (GRAs). GRAs developed for goals other than fun are called serious games. Within them, gamified assessments are serious games that share similarities with traditional assessments (questionnaires, situational judgment tests, etc.) but they incorporate game elements like story, music, and game dynamics. This paper aims to contribute to the research on serious games as an alternative to traditional personality questionnaires by analyzing the characteristics of a gamified assessment called VASSIP. This gamified assessment, based on an existing measure of the Big Five personality traits, incorporates game elements such as storyfication, immersion, and non-evaluable gamified dynamics. The study performed included 98 university students (77.6% with job experience) as participants. They completed the original personality measure (BFI-2-S), the gamified evaluation of personality (VASSIP), a self-report measure of the main dimensions of job performance (task performance, contextual performance, and counterproductive work behaviors), and measures of applicant reactions to BFI-2-S and VASSIP. Results showed that the gamified assessment behaved similarly to the original personality measure in terms of reliability and participants' scores, although the scores in Conscientiousness were substantially higher in VASSIP. Focusing on self-reports of the three dimensions of job performance, regression models showed that the gamified assessment could explain all of them. Regarding applicant reactions, the gamified assessment obtained higher scores in perceptions of comfort, predictive validity, and attractiveness, although the effect size was small except for the latter. Finally, all applicant reactions except for attractiveness were related to age and personality traits. In conclusion, gamified assessments have the potential to be an alternative to traditional personality questionnaires but VASSIP needs more research before its application in actual selection processes.

Italian adaptation of the Multidimensional Iowa Suggestibility Scale (MISS).

Background: Suggestibility is a personality trait that reflects a general tendency to accept messages. The Multidimensional Iowa Suggestibility Scale (MISS) is a self-report scale developed to measure the degree of individuals' perceptions of their suggestibility. This study aimed to adapt the MISS in an Italian sample. Methods: We conducted two studies. In the first study, 345 subjects (270 females (78%), mean age = 36.21 years ± 14.06 SD) completed the translated Italian version of the MISS, composed of five subscales (consumer suggestibility; persuadability; sensation contagion; physiological reactivity; peer conformity). We investigated the structural validity of the scale through confirmatory factor analysis (CFA) testing four measurement models (unidimensional, four-factor, hierarchical four factors, and bifactor) and explored reliability in terms of internal consistency through the McDonald's omega. In the second study, we cross-validated the MISS on a new independent sample. We enrolled 277 participants (196 females (71%), mean age 30.56, SD = 12.58) who underwent the new version of the scale. We performed factor analyses to test structural validity and compared four measurement models. Then, we investigated reliability and conducted a latent variable analysis to explore divergent validity. Results: The CFA in the first study revealed a bifactor solution of the MISS. This structure was interpretable and provided an adequate fit for the data. The final version of the scale was reduced to forty-six items with globally good indices of adaptation. The scale also demonstrated acceptable reliability in terms of internal consistency through the McDonald's Hierarchical Omega. In the second study, we found that the bifactor structure was confirmed. Factor loadings inspection revealed that there was no justification to report only the separate scores for the subscales. We also found that the scale showed good internal consistency, but mixed evidence for divergent validity. Conclusions: In the end, the Italian version of the MISS demonstrated good psychometric properties which will be discussed in detail below.

The impact of virtual reality scenes on stress response characteristics of individuals with different personality traits.

Virtual reality based physical stress (VRPS) paradigms could eliminate the influence of social factors on participants, and it may be a desirable tool to explore the impact of personality traits on stress levels. In this study, we attempt to explore the effects of VRPS on stress response among individuals with different personality traits. Forty male participants with an average age of 22.79 ± 0.41 years were divided into two groups based on Harm Avoidance (HA) scores of Tridimensional Personality Questionnaire (TPQ), referred to as the Low-HA group and the High-HA group. The stress levels of the participants were assessed using salivary α-amylase (sAA) activity and heart rate variability (HRV) indices pre- and post-stress. The influence of personality traits on stress response among different groups was analyzed. VRPS significantly affected the sAA activity and HRV indicators of both groups. During and after stress, there were significant differences in sAA activity and HRV indicators between the two groups. The sAA levels and HRV indices of the Low-HA group were lower than those of the High-HA group. Furthermore, sAA levels and HRV indices were correlated with the scores of TPQ. VRPS scenarios elicit different stress responses on individuals with different harm avoidance personality traits. Stress evaluation based on VR scenarios presents potential in personality trait assessments, particularly for distinguishing between individuals with low and high HA tendencies.

The Associations Among Observers' Openness to Experience and Agreeableness With Social Distance: The Moderating Role of Disability Type.

ABSTRACT: Despite abundant literature on personality and stigma, the role of disability type in this relationship has remained unaddressed. In the current study, we examined whether the relationship between observers' openness to experience and agreeableness on the one hand, and social distance on the other, was moderated by the target person's type of disability (psychiatric vs. physical). One hundred thirty-nine participants were randomly assigned to complete a social distance questionnaire referring to a vignette of a person in three conditions (physical disability, psychiatric disability, and control). A main effect of openness on social distance was found. Additionally, we found an interaction effect of agreeableness and the type of disability. Namely, the relationship between agreeableness and social distance was significant only in the physical disability condition but not in the other two conditions. To conclude, the current study emphasizes the role of personality traits in social distance toward individuals with disabilities.
