Investigation of risk factors associated with the development of depressive symptoms in healthy subjects exposed to long-term stress: A prospective study of the Japanese Antarctic research expedition wintering party.

Stressors induce depression together with parenting experienced in childhood, personality traits, and sleep. In this study, we investigated factors associated with the development of depression in a long-term stressful environment, namely, the Antarctic Research Expedition wintering party, by comparing 2 groups, the depression and nondepression groups. A self-administered questionnaire was used to survey 91 members of the Japanese Antarctic Research Expedition who spent winters in the Antarctic base. Psychological evaluations of depression, anxiety, and sleep were performed using a questionnaire every 3 months during the participants' stay in Antarctica. The primary endpoint was the occurrence of minor or major depression, as evaluated by the PHQ-9 score. Participants with a PHQ-9 score of 5 or more during their stay in Antarctica were defined as the depression group (25 subjects), and participants with a PHQ score of 4 or less were defined as the nondepression group (43 subjects). Compared with the nondepression group, the depression group had significantly higher scores for predeparture PHQ-9, state and trait anxiety, sleep disturbance, and neuroticism. Multivariable logistic regression analyses showed that higher predeparture scores of subthreshold depressive symptoms and neuroticism were found to be significant predictors of the occurrence of depression during their stay in Antarctica. This study prospectively showed that subthreshold depressive symptoms and neuroticism, which were suggested as risk factors in previous studies, were confirmed to be risk factors for depression. The results of our study are expected to contribute to the understanding of depression in harsh environments.

Understanding Schadenfreude in Politics: The Role of Big Five Personalities and Empathy

The euphoria of the Indonesian election has been replaced by an escalation of the conflict that is increasingly evident in society. The community seems to be looking for gaps in political figures and making jokes, both opponents and friends, even parties who are not part of the horizontal political conflict vortex. There is a phenomenon in a society where political events are used as material for good jokes and come from mistakes, politicians' mistakes become laughing stock, even being distributed as material for jokes together. The crisis of empathy is thought to make this phenomenon appear in society, but personality can also encourage the emergence of this behavior. This study aims to determine the role of empathy and personality in this case the big five personalities of voters against schadenfreude in election voters. Empathy is measured by the Interpersonal Reactivity Index scale, schadenfreude is measured by Schadenfreude, while the Big Five Inventory (BFI) scale is used to measure personality. 330 respondents were obtained in this study. This study uses a simple regression analysis and stepwise regression. The results of this study indicate that there is no role of empathy for schadenfreude in voters. Big Five Personality Traits have a stimulating role and a partial role towards schadenfreude, namely agreeableness, neuroticism, and openness traits. While the stimulant role between the Big Five Personality Traits on empathy was found in, there is a role partially between the traits agreeableness, neuroticism, conscientiousness, and openness to Schadenfreude to voters.

The impact of demoralization on the stability of personality traits in a clinical sample.

This study examined whether reductions in the severity of personality disorders (PD) mainly reflect changes in personality traits or rather an alleviation of a demoralized state involving nonspecific unpleasant affect. We used 4 years of longitudinal data from the Collaborative Longitudinal Personality Disorders Study, in which patients (N = 419) completed the Neuroticism-Extraversion-Openness Personality Inventory-Revised (NEO-PI-R) three times over 4 years (at baseline and at 6-month and 4-year follow-up assessments). We compared the NEO Demoralization scale with NEO-PI-R domain scales adjusted for demoralization-related items to determine whether changes in demoralization are more pronounced than changes in adjusted personality traits. Results showed that adjusted Neuroticism and Demoralization changed at similar rates and both changed more than other traits. These changes were most pronounced in the first 6 months and tapered thereafter. Rank-order correlations were somewhat lower for Demoralization than adjusted traits. Our findings suggest that decreases in PD symptoms over time have to do with reductions in negative affect and that Demoralization as assessed via a subset of NEO-PI-R items is limited in its ability to distinguish negative affect from trait Neuroticism.

Personality Traits and Quality of Life Among Older Adults: The Chain Mediating Effects of Perceived Social Support and Positive Coping Styles

The pathways between personality traits and older adults’ quality of life (QOL) have been well studied. However, perceived social support and positive coping styles should not be ignored by older adults’ QOL. Hence, this study examines the chain mediating role of perceived social support and positive coping styles between personality traits and older adults’ QOL. In total, 230 older individuals (Mean age = 69.43, SD age = 7.23, age range from 60 to 93) participated in this study. All older people provided a rating of QOL and perceived social support, the Chinese Big Five personality, and positive coping styles. (1a) the five personality traits of older adults were significantly associated with QOL; (2b) perceived social support mediated the relationship between three personality traits (neuroticism, extraversion, and agreeableness) and QOL; (3c) positive coping styles played a mediator role in the personality traits (neuroticism, extraversion, and agreeableness) and QOL; (4d) perceived social support and positive coping styles had a significant chain mediating effect on the three dimensions of personality traits (neuroticism, extraversion, and agreeableness) and QOL. As mediating influences, social support and positive coping styles can be applied to efforts to promote QOL for older adults who share the personality traits of neuroticism, extraversion, and agreeableness.

Do personality profiles contribute to patterns of physical activity and sedentary behavior in adulthood? A prospective cohort study

BackgroundDespite the observed associations of personality traits with levels of moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB), studies exploring whether the personality profiles differ in terms of the pattern of accumulation of physical behavior are lacking. The aim of this study was to identify adults’ personality profiles and to characterize and investigate how these profiles differ in physical behavior.MethodsThe study utilized the longitudinal data of the participants of the Jyväskylä Longitudinal Study of Personality and Social Development (n = 141–307). Information on the five-factor model of personality, including the traits of neuroticism, extraversion, conscientiousness, openness, and agreeableness, was collected at ages 33, 42, 50, and 61 years, and used to create latent personality profiles. Physical behavior, operationalized as the amount and accumulation of MVPA and SB bouts, was captured using a triaxial accelerometer worn during waking hours at age 61 years. The differences in the behavior between the personality profiles were analyzed using the Kruskal-Wallis test.ResultsFive personality profiles were identified: resilient (20.2%), brittle (14.0%), overcontrolled (9.8%), undercontrolled (15.3%), and ordinary (40.7%). Although there were no statistically significant differences between the personality profiles in the time spent in MVPA relative to SB (MVPA per hour of daily SB), individuals with resilient (low in neuroticism and high in other traits) and ordinary (average in each trait) profiles had MVPA-to-SB ratios of 0.12 (7 min) and those with a brittle (high in neuroticism and low in extraversion) profile had a ratio of 0.09 (5.5 min). The individuals in the resilient group exhibited a longer usual MVPA bout duration than those in the overcontrolled (low in extraversion, openness, and agreeableness) (8 min vs. 2 min) and undercontrolled (high in openness and low in conscientiousness) groups (8 min vs. 3 min). They also exhibited a longer usual SB bout duration than those in the ordinary group (29 min vs. 23 min).ConclusionsThe resilient group displayed the most prolonged MVPA and SB bout patterns. The results suggest that personality characteristics may contribute to how MVPA and SB are accumulated.

The Relationship between Five Factors Personality Traits of Nursing Students and Their Attitudes towards Mental Patients

This study aimed to reveal the relationship between the personal traits of nursing students and their attitudes toward mental Patients. The randomized sample consisted of (144) selected students in the Faculty of Nursing at Al al-Bayt University, their ages ranged from (18 to 22) years. The result concluded that nursing students’ attitudes toward mental patients were negative. It also indicated that the trait openness to experience has a significant negative correlation on all domains of attitudes toward mental patients scale, the correlation of the conscientiousness trait with the domains of attitudes toward mental disorders is not significant, and the extraversion trait has significant positive correlation with stereotyping, pessimism and stigma domains. The agreeableness trait has a significant negative correlation with all domains of attitudes toward mental disorders scale. The neuroticism trait has a significant negative correlation with the domain of the tendency towards pity in students' attitudes toward mental patients, while the rest of the domains of students' attitudes toward mental patients were not significant. The results also indicated that there are significant differences in all domains of the attitudes toward mental patients scale due to the gender variable in favor of males; That is, males had more negative attitudes toward mental patients than females. It is also clear that there are no significant differences for the variables of academic level and cumulative average in the dimensions of attitudes toward mental disorders. The study recommends creating educational programs to educate students about the importance of carrying positive attitudes toward mental patients, which contributes to reducing the problems of mental patients.

Who benefits from virtual collaboration? The interplay of team member expertness and Big Five personality traits

This research applies and integrates transactive memory systems (TMS) theory and the Big Five personality traits model to investigate the performance dynamics of dyadic teams engaged in virtual collaborative problem-solving (CPS). Specifically, this study examines how the personal attributes of team members, including their expertness and Big Five personality traits (extraversion, agreeableness, openness, conscientiousness, and neuroticism), as well as the resultant diversity in expertness and Big Five personality traits within teams, influence both team-level and individual-level performance gain from virtual collaboration. Studying 377 dyadic teams composed of 754 individuals working on an online collaborative intellective task, this research found that dyads with high expertness diversity had greater performance gain from virtual collaboration than dyads with low expertness diversity. Further, dyads, where both members scored low on agreeableness, showed the most significant improvement in team performance. At the individual level, a team member who had a low expertness level but was paired with a high-expertness teammate demonstrated the greatest performance gain from virtual collaboration. The integration of TMS theory and the Big Five personality traits model provides a richer and more nuanced understanding of how individual attributes and team dynamics contribute to successful virtual CPS outcomes.

Exploring the effect of demographic characteristics and personality traits on attitude toward AI-assisted second language learning among Chinese college students: A multiple regression analysis

Previous research underscores the pivotal role of AI in advancing second language (L2) learning, yet gaps persist in understanding how individual differences shape L2 learners’ perceptions of AI resources. Addressing this gap, this study explored the impact of demographic characteristics (age and gender) and personality traits (extroversion, agreeableness, conscientiousness, neuroticism, and openness) on attitude toward AI-assisted L2 learning. This attitude encompasses the opinions, feelings, and beliefs individuals hold about using AI as a tool to facilitate L2 learning. Data were collected from 493 L2 learners enrolled in Chinese colleges through an online questionnaire using two validated scales. Through SPSS 26, descriptive statistics indicated a moderately high positive attitude among students. Multiple regression analyses revealed that older students and females exhibited more favorable attitude compared to their younger and male counterparts, respectively. Additionally, personality traits—excluding agreeableness—significantly influenced attitude. Besides, extroversion and neuroticism negatively predicted attitude, whereas conscientiousness and openness had positive predictive effects. Moreover, this study discusses theoretical implications and offers educational insights while suggesting avenues for future research.

Personality Traits of Academic Librarians and Their Knowledge Acquisition and Application Behavior

Abstract This study investigated the effect of the Big Five personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness) on knowledge acquisition and application by Pakistani university librarians. To increase their impact in academic institutions, it is imperative to examine how people acquire and apply knowledge within the field of librarianship. This study employed a quantitative research approach based on the survey research method. The Big Five personality inventory designed by John and Srivastava was adopted, however, measurement items related to knowledge acquisition and application behavior were developed with the help of the existing literature. The study population comprised academic librarians working in the university libraries of Pakistan, with a census sampling method used to collect data and 357 completed questionnaires received. The results indicated that extraversion, agreeableness, and openness to experience positively affect the university librarian’s knowledge acquisition, while neuroticism has a negative effect. The findings also revealed that extraversion and openness to experience positively affects academic librarians’ knowledge application behavior while neuroticism has a negative effective, however, conscientiousness and agreeableness personality traits were found to be insignificant predictors of the same. This study highlights the significant personality features contributing to knowledge acquisition and application behavior in academic libraries from a developing country’s perspective.

The Relationship between Personality Traits and Turnover Intention of Private University Teachers: The Mediating Role of Sense of Belonging

This study examines the relationship between personality traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism) and turnover intention among private university teachers, focusing on the mediating role of sense of belonging. A quantitative research approach using Structural Equation Modeling (SEM) via SmartPLS 4.0 was employed. Data were collected from 781 private university teachers in Yunnan Province, China, through an online survey, and hypotheses were tested to explore the direct and indirect effects of the Big Five personality traits on turnover intention. The results reveal that openness, conscientiousness, and neuroticism are positively related to turnover intention, while agreeableness shows a significant negative relationship. Sense of belonging mediates the relationships between all personality traits and turnover intention, highlighting its critical role in reducing turnover. The study's cross-sectional design limits causal inference, and the specific context of Chinese private universities may affect generalizability. University administrators should focus on enhancing teachers' sense of belonging and tailor retention strategies based on individual personality traits. This study provides new insights into the complex interplay between personality traits, sense of belonging, and turnover intention in educational settings, offering practical recommendations for improving teacher retention.

A Two-Sample Mendelian Randomization Study of Neuroticism and Sleep Bruxism

Sleep bruxism (SB) affects a considerable part of the population and is associated with neuroticism, stress, and anxiety in various studies. However, the causal mechanisms between neuroticism and SB have not been examined. Understanding the reasons for SB is important as understanding bruxism may allow improved comprehensive management of the disorders and comorbidities related to it. Previous studies on the association of risk factors to SB have provided important symptomatic insight but were mainly questionnaire based or limited in sample size and could not adequately assess causal relationships. The aim of this study was to elaborate the possible causal relationship of neuroticism as a risk factor for SB through a Mendelian randomization (MR) approach by combining questionnaires, registry data, and genetic information in large scale. We performed a two-sample MR study using instrumental genetic variants of neuroticism, including neuroticism subcategories, in the UK Biobank (n = 380,506) and outcome data of probable SB using FinnGen (n [cases/controls] = 12,297/364,980). We discovered a causal effect from neuroticism to SB (odds ratio [OR] = 1.38 [1.10–1.74], P = 0.0057). A phenotype sensitive to stress and adversity had the strongest effect (OR = 1.59 [1.17–2.15], P = 0.0028). Sensitivity analyses across MR methods supported a causal relationship, and we did not observe pleiotropy between neuroticism and SB (MR-Egger intercept, P = 0.87). Our findings are in line with earlier observational studies that connect stress and SB. Furthermore, our results provide evidence that neurotic traits increase the risk of probable SB.

PERSONALITY TRAITS AND SOCIOECONOMIC STATUS OF POSTGRADUATE STUDENTS TOWARDS IMPOSTOR SYNDROME

Impostor syndrome (IS) is a psychological phenomenon characterized by feelings of incompetence and self-doubt regarding one's achievements, despite external evidence of success. This study aimed to examine the relationship between the personality trait of neuroticism, socioeconomic status, and impostor syndrome among postgraduate students at the National University of Malaysia (UKM). A total of 365 postgraduate students from various disciplines participated in this study. Data were collected using an online questionnaire that measured neuroticism, socioeconomic status, and impostor syndrome. However, there was a weak association between socioeconomic status and impostor syndrome. These findings suggest that neuroticism plays a crucial role in the development of impostor syndrome among postgraduate students, while socioeconomic status has a minimal influence. The implications of this study are important for developing appropriate interventions to address IS among postgraduate students, focusing on emotional management and enhancing self-confidence.

Social Anxiety among Middle-Aged Teachers in Secondary Education Schools.

This study aimed to investigate the prevalence of social anxiety symptoms (SASs) and its associated factors among middle-aged teachers in secondary education schools. A cross-sectional survey was conducted from December 2023 to March 2024 among 341 secondary education schoolteachers aged 45-59 in Chiang Mai, Thailand, involving an online survey. Effects of psychosocial variables on SASs were investigated, including attachment anxiety, attachment avoidance, neuroticism and extraversion personality traits, loneliness, perceived social stress, job burnout, and anxiety and depression. Multiple linear regression was used to identify predictors of SASs. This study found that 98 out of 341 (28.7%) teachers presented SASs. Multiple linear regression analysis showed that marital status (β = 0.103, 95% CI [0.437, 3.404]), income (β = 0.087, 95% CI [0.049, 3.758]), extraversion (β = -0.179, 95% CI [-0.573, -0.198]), attachment anxiety (β = 0.165, 95% CI [0.106, 0.359]), attachment avoidance (β = 0.145, 95% CI [0.066, 0.243]), depression (β = 0.242, 95% CI [0.248, 0.862]), loneliness (β = 0.182, 95% CI [0.099, 0.580]), and perceived social stress (β = 0.235, 95% CI [0.131, 0.373]) were significant predictors of SASs, explaining 51.1% of the variance. This study discovered a relatively high prevalence of SASs among middle-aged secondary schoolteachers.

PERSONALITY TRAITS AND ORGANIZATIONAL SUPPORT AS PREDICTORS OF WORK-LIFE BALANCE AMONG SHOPRITE WORKERS

Personality traits and organizational support as predictors of work-life balance among shoprite workers. Work-life balance has become an emerging issue where bothorganization and employees tend to benefit. However no consistent results have been obtained using different predictors. Therefore, this study investigated personality traits and organizational support as predictors of work-life balance among workers in Shoprite in Ibadan metropolis. The study adopted a cross-sectional survey design while purposive sampling technique was used to select one superstore: Shoprite in Ibadan. Data were collected from 200 participants using three validated scales and analyzed using t-test of independent samples and multiple regressions analysis. Three hypotheses were tested and accepted at a p < 0.05 level of significance. The result indicated that perceived organizational support significantly influenced work-life balance [t (198) = 2.12, p <..05] among study participants. Also, the result revealed that personality traits of extraversion, agreeableness, conscientiousness, neuroticism and openness to experience jointly predicted work-life balance among workers (R2 = 0.04, F (5, 191) = 1.64, p < 0.05). Furthermore, personality traits and organizational support jointly predicted work-life balance among study participants (R2 = 0.08, F (6,190) = 2.89, p < 0.05). However, only perceived organizational support independently predicted work-life balance. The study concluded that personality traits and organizational support are good predictors of work-life balance among study participants. It is recommended that workers should learn self-and time-management techniques to achieve maximum

Personality Traits And Non Suicidal Self Injury In University Students

The study aimed to assess the relationship of personality traits (neuroticism, extraversion, agreeableness, conscientiousness and openness to experiences) with Non Suicidal Self Injury (NSSI) in University students. It was hypothesized that there is likely to be significant positive relationship of neuroticism with NSSI while significant negative relationship of extraversion, agreeableness, conscientiousness, and openness to experiences with NSSI was assumed [1]in University students. The sample comprised of three hundred university students who full filled DSM-5 criteria of NSSI (M=19.97, SD=1.62). The assessment measures used were: Demographic Form, The DSM-5 Level 1 Cross-Cutting Symptom Measure (APA-2013), The Big Five Personality Inventory (John & Srivastava, 1999) and The Alexian Brothers Assessment of Self-Injury (Washburn et al., 2015).The finding revealed significant positive relationship of neuroticism and NSSI while significant negative relationship of agreeableness, extraversion and conscientiousness with NSSI in University students. The study have implications for early detection, tailored interventions and prevention of NSSI.

Unraveling the nexus: exploring the interplay of mass media, personality traits and social norms in fostering protective behavior against smog

Purpose The rise in industrialization, economic development and urbanization has altered the composition of atmospheric air. Air pollutants have significantly impacted Pakistan's urban areas, resulting in the lowest air quality index readings. To understand disinclined behavior such as using air purifiers and wearing masks, this study aims to explore the relationship between individual personality traits and mass media effects. Design/methodology/approach This study used a cross-sectional survey with a model based on previous theories. Data from 2,000 adults were self-administered and analyzed using partial least squares structural equation modeling (PLS-SEM). Findings PLS-SEM confirmed six hypotheses, revealing mass media's direct and mediating roles in promoting critical psychological perceptions for protective behavior. The empirical results indicate that neuroticism, agreeableness and openness traits reinforce adherence behavior by intensifying threat perception. Practical implications This paper highlights significant implications for media campaign planners and provides more precise and comprehensive theoretical guidance. In the context of environmental challenges like smog, the findings illustrate how an understanding of personality traits can improve the efficacy of public health interventions through adherence to behaviors like mask-wearing and air purifier use. Addressing individual psychological characteristics when creating mass media campaigns to encourage public adherence to health protection measures related to environmental hazards. Originality/value Despite health campaigns and awareness, public compliance with measures like mask-wearing and air purifier use remains minimal. This study explores untapped mass media effects based on individual personality traits to understand this behavior.

The Relationship between Big Five Personality Traits and Depression in the German-Speaking D-A-CH Region Including an Investigation of Potential Moderators and Mediators.

Considerable evidence links the "Big Five" personality traits (neuroticism, extroversion, conscientiousness, agreeableness, and openness) with depression. However, potential mediating and moderating factors are less well understood. We utilized data from a cross-sectional survey of 3065 German-speaking adults from the D-A-CH region to estimate multivariable-adjusted odds ratios and 95% confidence intervalsbetween personality traits and lifetime prevalence of depression (overall and stratified by sex and age). We further explored proportions mediated by psychosocial factors optimism, empathy, perspective-taking, work-life balance, and interpersonal trust. High levels of neuroticism were associated with more than two-fold higher odds of depression, whereas higher levels of conscientiousness were associated with approximately 30% lower odds of depression. The association with neuroticism persisted in all investigated subgroups; apparently, stronger associations for females and participants aged ≥60 years did not correspond to statistically significant interactions. Overall and across all strata, the association of neuroticism with depression appeared to be mediated in part by the considered psychosocial factors; optimism explained the largest proportion of the association. Our results provide empirical evidence for the dynamic predisposition model. Further investigations of these relationships are warranted in longitudinal data with more precise outcome assessments.

LSD-assisted therapy in patients with anxiety: open-label prospective 12-month follow-up.

Anxiety disorders are a major public health burden with limited treatment options. We investigated the long-term safety and efficacy of lysergic acid diethylamide (LSD)-assisted therapy in patients with anxiety with or without life-threatening illness. This study was an a priori-planned long-term follow-up of an investigator-initiated, two-centre trial that used a double-blind, placebo-controlled, two-period, random-order, crossover design with two sessions with either oral LSD (200 μg) or placebo per period. Participants (n = 39) were followed up 1 year after the end-of-study visit to assess symptoms of anxiety, depression and long-term effects of psychedelics using Spielberger's State-Trait Anxiety Inventory-Global (STAI-G), the Beck Depression Inventory (BDI), the Persisting Effects Questionnaire and measures of personality traits using the NEO-Five-Factor Inventory. Participants reported a sustained reduction of STAI-G scores compared with baseline (least square means (95% CI) = -21.6 (-32.7, -10.4), d = 1.04, P < 0.001, for those who received LSD in the first period (94 weeks after the last LSD treatment) and -16.5 (-26.2, -6.8), d = 1.02, P < 0.05, for those who received LSD in the second period (68 weeks after the last LSD treatment)). Similar effects were observed for comorbid depression with change from baseline BDI scores of -8.1 (-13.2, -3.1), d = 0.71, P < 0.01, and -8.9 (-12.9, -4.9), d = 1.21, P < 0.01, for the LSD-first and placebo-first groups, respectively. Personality trait neuroticism decreased (P < 0.0001) and trait extraversion increased (P < 0.01) compared with study inclusion. Individuals attributed positive long-term effects to the psychedelic experience. Patients reported sustained long-term effects of LSD-assisted therapy for anxiety.
