Neuroticism and Stress in Older Adults: The Buffering Role of Self-Esteem.

Chronic stress is associated with accelerated aging and poor health outcomes in older adults. According to the Transactional Model of Stress (TMS), distress is experienced when one perceives the stressor, or threat, to outweigh the ability to cope. The experience of distress is correlated with trait neuroticism, which is associated with greater perceptions of stress and stress reactivity, as well as a tendency to engage in maladaptive coping strategies. However, as individual personality traits do not act in isolation, this study aimed to investigate the moderating role of self-esteem in the relationship between neuroticism and distress using a TMS framework. A total of 201 healthy older adults (Mage = 68.65 years) completed questionnaires measuring self-esteem, neuroticism, perceived stress, and positive coping. Greater neuroticism was significantly associated with less positive coping at low (b = -0.02, p < 0.001) and mean self-esteem levels (b = -0.01, p < 0.001), but not at high self-esteem levels (b = -0.01, p = 0.06). No moderating effect was found for perceived stress or overall distress. The results support the association between trait neuroticism and indices of stress and suggest a potential buffering effect of self-esteem in moderating the negative association between neuroticism and positive coping.

Prevalence and therapeutic impact of adverse life event reexperiencing under ceremonial ayahuasca

The present study examined the safety and efficacy of the ceremonial use of ayahuasca in relation to reports of heightened life event reexperiencing under psychedelics. The study examined (1) the prevalence of specific types of adverse life event reexperiencing, (2) characteristics predictive of reexperiencing, (3) the psychological character of reexperiencing, and (4) the impact of reexperiencing on mental health. Participants were recruited from three ayahuasca healing and spiritual centers in South and Central America (N = 33 military veterans, 306 non-veterans) using self-report data at three timepoints (Pre-retreat, Post-retreat, 3-months post-retreat). Reexperiencing adverse life events under ayahuasca was common, with women showing particularly high probability of reexperiencing sexual assault, veterans reexperiencing combat-related trauma, and individuals with a self-reported lifetime diagnosis of post-traumatic stress disorder exhibiting a substantively higher prevalence of reexperiencing. Reexperiencing was associated with states of cognitive reappraisal, psychological flexibility, and discomfort during ceremonies, and participants who reexperienced adverse life events exhibited greater reductions in trait neuroticism following their ceremonies. Clinical implications of these results for the application of psychedelics to mood and stress disorders are discussed.

OCEAN Traits as Key Determinants of Knowledge Sharing Behaviour through Short-video Social Commerce Platforms

This study aimed to examine the determinants of knowledge sharing behavior on a short-video social commerce platform by integrating the framework of OCEAN Traits and knowledge sharing behavior. A questionnaire-type survey was used, and responses from 200 TikTok short-form video platform users were analyzed against the research model, and the hypotheses were tested by employing partial least squares structural equation modeling. The findings reveal that Extraversion and Neuroticism traits were significant determinants of knowledge sharing behavior, whereas Openness to Experience, Conscientiousness, and Agreeableness traits failed to predict knowledge sharing behavior through short videos on the social commerce platform. The findings present several implications for researchers in the extraversion and neuroticism traits as key determinants of knowledge sharing behavior in the short-video social commerce platform context. The results will be beneficial to online business operators and their stakeholders who use short-video social commerce platforms to implement business strategies that promote buying decisions for products and services.

School Bullying and Personality Traits from Elementary School to University

This retrospective study examines involvement in school bullying at all developmental stages, from elementary school to university, in relation to personality traits. Participants were 216 university students, 162 (75.0%) females and 54 (25.0%) males. The majority of the sample (88.9%) aged 18–24. Students completed the International Personality Items Pool (BFFM) and a self-report questionnaire about school bullying online. The results show that the involvement roles in personality trait A3 (don’t insult) of the Agreeableness (A) scale differ significantly at all educational levels. However, trait E6 Extraversion (E) and the Conscientiousness (C) scale differ at the elementary school level, and trait N6 of the Neuroticism (N) scale varies at the middle school and N3 differs at the high school. All participants differ statistically significantly in A3, Conscientiousness scale at all educational levels. Those involved differ statistically significantly in the traits Neuroticism, C8, and C9 and in two traits of Openness (O). Throughout the course of schooling, victims showed a higher score on the Conscientiousness scale than the bullies/victims. The victims who became the bullies (victims/bullies) had a higher score on the Emotional Stability scale than the bullies who became victims (bullies/victims). About half of the participants said that the experience affected them positively and the other half negatively. Those who answered that it had a positive impact on them showed a statistically significant difference in characteristics E7 (talkativeness) and N10 (pleasant mood). The findings help inform a new perspective of anti-bullying intervention that targets personality traits in all the roles and their rotation.

Prevalência do transtorno do jogo pela internet e seus correlatos psicológicos

ABSTRACT Objective To investigate the prevalence of internet gaming disorder (IGD) symptoms in a sample of Brazilian adults, and its association with personality, psychiatric symptoms and psychosocial measures. Methods We evaluated 219 adults online recruited using questionnaires and psychometric scales. We evaluated the behavior and pattern of internet games using the Game Addiction Scale (GAS). We tested the association of the previous measures with the GAS scores by spearman correlations and multiple regression analysis. Results Of our sample, 74% played games online. We found correlations between IGD symptoms and most symptoms of mental disorders, with small or moderate effect sizes, as well as correlations with the personality traits of agreeableness (r = -0.272; p &lt; 0.001), conscientiousness (r = - 0.314; p &lt; 0.001), and neuroticism (r = 0.299; p &lt; 0.001). Additionally, we found a negative association with psychosocial outcomes such as quality of life (r = -0.339; p &lt; 0.001) and life satisfaction (r = - 0.202; p &lt; 0.003). The multivariate model included the personality traits of conscientiousness and agreeableness and symptoms of dissociation and somatization as predictors. The prevalence of IGD was 9% in those who played online games. Conclusion IGD is correlated with different areas of the individual’s life, such as personality, quality of life, and several common symptoms of mental disorders. The prevalence can be considered high among players (9%). Conscientiousness, agreeability, somatic symptoms, and dissociative symptoms were associated with the symptoms of IGD.

Emotional (in)stability: Neuroticism is associated with increased variability in negative emotion after all

The personality trait neuroticism is tightly linked to mental health, and neurotic people experience stronger negative emotions in everyday life. But, do their negative emotions also show greater fluctuation? This commonsensical notion was recently questioned by [Kalokerinos et al. Proc Natl Acad Sci USA 112, 15838-15843 (2020)], who suggested that the associations found in previous studies were spurious. Less neurotic people often report very low levels of negative emotion, which is usually measured with bounded rating scales. Therefore, they often pick the lowest possible response option, which severely constrains the amount of emotional variability that can be observed in principle. Applying a multistep statistical procedure that is supposed to correct for this dependency, [Kalokerinos et al. Proc Natl Acad Sci USA 112, 15838-15843 (2020)] no longer found an association between neuroticism and emotional variability. However, like other common approaches for controlling for undesirable effects due to bounded scales, this method is opaque with respect to the assumed mechanism of data generation and might not result in a successful correction. We thus suggest an alternative approach that a) takes into account that emotional states outside of the scale bounds can occur and b) models associations between neuroticism and both the mean and variability of emotion in a single step with the help of Bayesian censored location-scale models. Simulations supported this model over alternative approaches. We analyzed 13 longitudinal datasets (2,518 individuals and 11,170 measurements in total) and found clear evidence that more neurotic people experience greater variability in negative emotion.

0067 Dreams and Personality Influence Creativity

Abstract Introduction Theoretically, during dreaming, weak associations are explored, and information is combined in novel ways, which could lead to increased creativity during waking. However, little research has explored direct relationships between dreaming and objective measures of creativity and the ability to creatively solve problems. Furthermore, personality influences dream recall frequency (DRF) and other aspects of dreaming, suggesting that the relationship between dreaming and creativity may vary based on personality. The goal of the current experiment was to determine if DRF is related to creativity and creative problem-solving, and if these relationships are influenced by personality traits. Methods Seventy-six participants completed questionnaires about dreaming and the Big 5 personality traits (neuroticism, conscientiousness, openness, extraversion, agreeableness) and completed creativity and creative problem-solving tasks. Two tasks measured creativity. In one task, participants generated as many possible uses for an object as they could in one minute. In the other, they generated novel captions for five cartoons. Creative problem-solving was measured using two classic insight problem sets: the matchstick and compound remote associates tasks. Correlations were conducted to determine if DRF is related to any personality traits and multiple regressions were conducted to determine whether DRF or any personality traits predict creativity or creative problem-solving. Results DRF was negatively correlated with agreeableness, such that individuals higher in agreeableness recalled fewer dreams. The multiple regression analyses revealed that both DRF and conscientiousness are significant predictors of divergent thinking. Neither DRF nor any personality traits predicted creative problem-solving. Conclusion These results indicate that agreeableness reduces the frequency of dream recall, perhaps because agreeable individuals try to find problem solutions immediately while awake so they do not worry about them later. Consistent with current theories, frequently recalling dreams increased creativity, suggesting that the exploration of weak or novel relationships during dreaming increases creativity while awake. Conscientiousness also predicted creativity, suggesting that self-sufficient people tend to be more creative. However, frequently recalling dreams did not increase the ability to creatively solve problems. Collectively, these results suggest that personality influences dreaming behaviors and that frequent dreaming and conscientiousness promote creativity. Support (if any)

Personality Traits and Resilience of People with Bereaved Experiences Due to COVID-19: Mediating Role of Self-Efficacy

Worldwide, the mortality due to SARS-CoV-2 has been inclined to around 68 million by the end of January 2023. Many people lost their family members due to the virus attack or its comorbid complications. Mourning the loss of a loved one is a painful time, but the ability to handle this stress may vary from person to person. It could be a result of their personality traits and inner capabilities, such as self-efficacy. This study aimed to understand the role of personality traits and self-efficacy on the resilience of bereaved individuals. Convenience sampling was employed to recruit a total of 237 participants who had lost loved ones to COVID-19 (father, mother, grandfather, grandmother, uncle, aunt, and distant relatives). After explaining the objective of the study and taking informed consent, they were administered using brief resilience scale, a big five personality inventory, and general self-efficacy questionnaire. Self-efficacy and resilience were found to have a positive correlation, while neuroticism and resilience had a negative correlation. In addition, the mediation analysis revealed that self-efficacy acted as an important mediator between personality traits (Openness, agreeableness, conscientiousness, and neuroticism) and resilience. Individuals with strong self-efficacy were able to return to their usual state more quickly than those with low self-efficacy, as indicated by the results. However, attributes such as openness, agreeableness, and conscientiousness, together with self-efficacy, might enhance resilience. Therefore, the study strongly suggests incorporating self-efficacy into the design of therapeutic programs for coping with bereavement.

The relationship between personality traits and individual factors with perinatal depressive symptoms: a cross-sectional study

BackgroundPregnancy is a crucial transition moment exposing women to potential mental health problems, especially depressive disturbances. Sociodemographic, pregnancy-related, and psychological factors have been related to depressive symptoms in the perinatal period. This study aims at (1) exploring personality and individual factors related with perinatal depressive symptoms, and (2) testing the mediating role of personality in the relation between characteristics of the woman’s family of origin and depressive symptoms.MethodsWomen in the perinatal period admitted to the gynecology unit for motherhood-related routine assessments (n = 241) were included in the study. A survey on individual sociodemographic, clinical, and pregnancy-related factors was administered, also including the Edinburgh Postnatal Depression Scale (EPDS) and the BIG-5 personality test.ResultsCouple conflict and neuroticism were independent and directly correlated with EPDS total score (respectively: B = 2.337; p = .017; B = 0.303; p < .001). Neuroticism was a significant mediator of the relation between the presence of a psychiatric disorder diagnosis in participant’s parents and the EPDS total score (indirect b = 0.969; BCCI95%=0.366—1.607).ConclusionsCouple relation and neuroticism traits are individual factors related to depressive symptoms in the perinatal period. The family of origin also plays an indirect role on perinatal depressive symptoms. Screening of these factors could lead to early recognition and more tailored treatments, ultimately leading to better outcome for the entire family.

Personality traits and substance use among college students in Eldoret, Kenya.

There is documented evidence of the increase of alcohol and substance use among college students globally. Increased morbidity and associated maladaptive socio-occupational outcomes of the habit with early dependence and mortality have also been reported. Majority of the substance use related studies conducted in low- and middle- income countries mainly look at health- related risk behaviour control mechanisms that focus on the social environment domain, with few or almost none focusing on those embedded within the person (self- control). This study focuses on the relationship between substance use and personality traits (in the self-control domain), among college students in a low- middle- income country. Design. A cross- sectional descriptive study that used the self- administered WHO Model Core and the Big Five Inventory Questionnaires to collect information among students in Colleges and Universities in Eldoret town, Kenya. Setting. Four (1- university campus; 3- non- university) tertiary learning institutions were randomly selected for inclusion. Subjects. Four hundred students, 100 from each of the 4 institutions; selected through a stratified multi-stage random sampling, who gave consent to participate in the study. Associations between various variables, personality traits and substance use were tested using bivariate analysis, while the strength/ predictors of association with substance use was ascertained through multiple logistic regression analyses. A finding of p ≤ 0.05 was considered statistically significant. The median age was 21 years (Q1, Q3; 20, 23), approximately half 203 (50.8%) were male, with majority 335 (83.8%) from an urban residence and only 28 (7%) gainfully employed. The lifetime prevalence of substance use was 41.5%, while that of alcohol use was 36%. For both, a higher mean neuroticism score [substance use- (AOR 1.05, 95%CI; 1, 1.10: p = 0.013); alcohol use- (AOR 1.04, 95%CI; 0.99, 1.09: p = 0.032)] showed increased odds of lifetime use, while a higher mean agreeableness score [substance use- (AOR 0.99, 95%CI; 0.95, 1.02: p = 0.008); alcohol use- (AOR 0.99, 95%CI; 0.95, 1.02: p = 0.032)] showed decreased odds of lifetime use. A higher mean age (AOR 1.08, 95% CI; 0.99, 1,18: p = 0.02) of the students also showed an 8% increase in odds of lifetime alcohol use. The lifetime prevalence of cigarette use was 8.3%. Higher mean neuroticism (AOR 1.06, 95%CI; 0.98, 1.16: p = 0.041) and openness to experience (AOR 1.13, 95%CI; 1.04, 1.25: p = 0.004) scores showed increased odds of lifetime cigarette smoking, whereas being unemployed (AOR 0.23, 95%CI; 0.09, 0.64: p<0.001) had a decreased odd. Other substances reported included cannabis 28 (7%), sedatives 21 (5.2%), amphetamines 20 (Catha edulis) (5%), tranquilizers 19 (4.8%), inhalants 18 (4.5%), cocaine 14 (3.5%), with heroin and opium at 10 (2.5%) each. Among the 13 participants who reported injecting drugs, 10 were female and only 3 were male; this finding was statistically significant (p = 0.042). The prevalence of substance use among college and university students in Eldoret is high and associated with high neuroticism and low agreeableness personality traits. We provide directions for future research that will examine and contribute to a deeper understanding of personality traits in terms of evidence- based approach to treatment.

The robustness of individual differences in gaze preferences toward faces and eyes across face-to-face experimental designs and its relation to social anxiety.

Humans rely heavily on the visual and oculomotor systems during social interactions. This study examined individual differences in gaze behavior in two types of face-to-face social interactions: a screen-based interview and a live interview. The study examined how stable these individual differences are across scenarios and how it relates to individuals' traits of social anxiety, autism, and neuroticism. Extending previous studies, we distinguished between individuals' tendency to look at the face, and the tendency to look at the eyes if the face was fixated. These gaze measures demonstrated high internal consistencies (correlation between two halves of the data within a scenario) within both the screen-based and live interview scenarios. Furthermore, individuals who had a tendency to look more at the eyes during one type of interview tended to display the same behavior during the other interview type. More socially anxious participants looked less at faces in both scenarios, but no link with social anxiety was observed for the tendency to look at the eyes. This research highlights the robustness of individual variations in gaze behavior across and within interview scenarios, as well as the usefulness of measuring the tendency to look at faces separately from the tendency to look at eyes.

Surgeons of the Future: A Novel Screening Tool for High-School Students

IntroductionGiven a looming shortage of surgeons and currently inadequate pipelines into our specialty for under-represented groups, there is an urgent need to identify and foster interest in young individuals who may have great potential as future surgeons. We aimed to explore the utility and feasibility of a novel survey instrument to identify high-school students well suited for careers in surgery based on personality profiling and grit. MethodsAn electronic screening tool was developed, combining components of the Myers-Briggs personality profile, the Big-Five Inventory 10, and the grit scale. This brief questionnaire was electronically distributed to surgeons and students across two academic institutions and three high schools (one private and two public). Wilcoxon rank-sum test and Chi-squared/Fisher's exact test were performed to evaluate variations between groups. ResultsSurgeons (n = 96) displayed mean Grit score of 4.03 (range: 3.08-4.92; standard deviation: 0.43), while high-schoolers’ (n = 61) mean score was 3.38 (range: 2.08-4.58; standard deviation: 0.62) (P < 0.0001). Surgeons showed Myers-Brigg Type Indicator trait-dominance toward extroversion, intuition, thinking, and judging, while students displayed greater breadth of traits. Students were much less likely to show dominance in introversion versus extroversion (P < 0.0001) as well as perceiving versus judging (P < 0.0001). Big-Five Inventory 10 traits of neuroticism and conscientiousness were more prevalent among surgeons (P < 0.0001 for both). ConclusionsImportantly, there exists a subgroup of high-school students with personality and grit similar to those of surgeons. Moreover, we have demonstrated the feasibility of using this novel screening tool for future studies aimed to create pipelines for early exposure opportunities and mentorship.

A Traitlike Dimension of Subjective Memory Concern Over 30 Years Among Adult Male Twins

Subjective memory concern has long been considered a state-related indicator of impending cognitive decline or dementia. The possibility that subjective memory concern may itself be a heritable trait is largely ignored, yet such an association would substantially confound its use in clinical or research settings. To assess the heritability and traitlike dimensions of subjective memory concern and its clinical correlates. This longitudinal twin cohort study was conducted from 1967 to 2019 among male adults with a mean (SD) age of 37.75 (2.52) years to follow-up at mean ages of 56.15 (2.72), 61.50 (2.43), and 67.35 (2.57) years (hereafter, 38, 56, 62, and 67 years, respectively) in the Vietnam Era Twin Study of Aging. The study included a national community-dwelling sample with health, education, and lifestyle characteristics comparable to a general sample of US men in this age cohort. Participants were monozygotic and dizygotic twins randomly recruited from the Vietnam Era Twin Registry. Data were analyzed from May 2021 to December 2022. Measures included subjective memory concern at 4 time points; objective memory, depressive symptoms, and anxiety at the last 3 time points; negative emotionality (trait neuroticism) at age 56 years; polygenic risk scores (PRSs) for neuroticism, depression, and Alzheimer disease; APOE genotype; and parental history of dementia. Primary outcomes were heritability and correlations between subjective memory concern and other measures. The sample included 1555 male adults examined at age 38 years, 520 at age 56 years (due to late introduction of subjective memory concern questions), 1199 at age 62 years, and 1192 at age 67 years. Phenotypically, subjective memory concerns were relatively stable over time. At age 56 years, subjective memory concern had larger correlations with depressive symptoms (r, 0.32; 95% CI, 0.21 to 0.42), anxiety (r, 0.36; 95% CI, 0.18 to 0.51), and neuroticism (r, 0.34; 95% CI, 0.26 to 0.41) than with objective memory (r, -0.24; 95% CI, -0.33 to -0.13). Phenotypic results were similar at ages 62 and 67 years. A best-fitting autoregressive twin model indicated that genetic influences on subjective memory concern accumulated and persisted over time (h2 = 0.26-0.34 from age 38-67 years). At age 56 years, genetic influences for subjective memory concern were moderately correlated with genetic influences for anxiety (r, 0.36; 95% CI, 0.18 to 0.51), negative emotionality (r, 0.51; 95% CI, 0.44-0.57), and depressive symptoms (r, 0.20; 95% CI, 0.10 to 0.29) as well as objective memory (r, -0.22; 95% CI, -0.30 to -0.14). Similar genetic correlations were seen at ages 62 and 67 years. The neuroticism PRS was associated with subjective memory concern at age 38 years (r, 0.10; 95% CI, 0.03. to 0.18) and age 67 years (r, 0.09; 95% CI, 0.01 to 0.16). Subjective memory concern was not associated with any Alzheimer disease risk measures. This cohort study found stable genetic influences underlying subjective memory concern dating back to age 38 years. Subjective memory concern had larger correlations with affect-related measures than with memory-related measures. Improving the utility of subjective memory concern as an indicator of impending cognitive decline and dementia may depend on isolating its statelike component from its traitlike component.

The Big Five as Predictors of Cognitive Function in Individuals with Bipolar Disorder.

The connection between cognitive function and the "Big Five" personality traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism) in the general population is well known; however, studies researching bipolar disorder (BD) are scarce. Therefore, this study aimed to investigate the Big Five as predictors of executive function, verbal memory, attention, and processing speed in euthymic individuals with BD (cross-sectional: n = 129, including time point t1; longitudinal: n = 35, including t1 and t2). Participants completed the NEO Five-Factor Inventory, the Color and Word Interference Test, the Trail Making Test, the d2 Test of Attention Revised, and the California Verbal Learning Test. The results showed a significant negative correlation between executive function and neuroticism at t1. Changes in cognitive function between t1 and t2 did not correlate with and could not be predicted by the Big Five at t1. Additionally, worse executive function at t2 was predicted by higher neuroticism and lower conscientiousness at t1, and high neuroticism was a predictor of worse verbal memory at t2. The Big Five might not strongly impact cognitive function over short periods; however, they are significant predictors of cognitive function. Future studies should include a higher number of participants and more time in between points of measurement.

Events-Affect-Personality: A Daily Diary Investigation of the Mediating Effects of Affect on the Events-Personality Relationship.

Our 10-day diary investigation anchored in dynamic personality theories, such as Whole Trait Theory examined (a) whether within-person variability in two broad personality traits Extraversion and Neuroticism is consistently predicted by daily events, (b) whether positive and negative affect, respectively partly mediate this relationship and (c) the lagged relationships between events, and next day variations in affect and personality. Results revealed that personality exhibited significant within-person variability, that positive and negative affect partly mediate the relationship between events and personality, affect accounting for up to 60% of the effects of events on personality. Additionally, we identified that event-affect congruency was accountable for larger effects compared to event-affect non-congruency.

Relationship between the Authentic Leadership and Big Personality Trait of Neuroticism: An Empirical Study

The scope of study that has been done on the significant personality impact of neuroticism on authentic leadership has been relatively minimal. Using a correlational method, this study aims to investigate the relationship between neuroticism's primary personality trait and authentic leadership's components (self-awareness, internalized moral perspective, balanced processing, and relational transparency). The authentic leadership questionnaire (ALQ) is used to examine leaders' personalities and authentic leadership styles. The results of this research showed that there is a negative correlation between neuroticism and all authentic leadership dimensions. This was the key takeaway from the study.

Personality traits and pattern of beliefs of near-death(-like) experiencers.

Little is known about the potential personality and psychological predictors of near-death experiences (NDEs), and fewer yet those of near-death-like experiences (NDEs-like; similar phenomenology reported after a non-life-threatening context). This study investigated whether personality traits (Openness, Extraversion, Pleasantness, Conscientiousness, and Neuroticism), dissociative experiences, Fantasy proneness, disposition toward auditory hallucinations, absorption trait, and endorsement of paranormal and spiritual beliefs could be associated with the recall of NDEs(-like). To this aim, we invited four groups of people to retrospectively fill in questionnaires assessing the following factors: NDE experiencers (n = 63), NDE(-like) experiencers (n = 31), controls with a life-threatening situation but no NDE(-like) (n = 43), and controls without a life-threatening situation or an NDE(-like) (n = 44). We carried out univariate analyses for each factor and then performed a multiple regression analysis and a discriminant analysis. The multivariate logistic regression analysis revealed that the endorsement of spiritual beliefs was associated with the recall of NDEs-like while Openness and Fantasy proneness were associated with the recall of NDEs. The discriminant analysis showed that these variables produce 35% of correct classification. Albeit retrospective, these results pave the way for future research on psychological predictors of NDEs(-like) by highlighting the influence of Spirituality, Openness, and Fantasy proneness on these phenomena.

Relationship of Gaming Disorder with parenting based on low affection-communication and personality trait of neuroticism in adolescents.

Gaming Disorder is increasingly common in adolescents. We aimed to evaluate the relationship between parenting, personality traits, and Gaming Disorder. An observational and cross-sectional study in six secondary schools of Castelló, obtaining a final sample of 397 students. Adolescents with Gaming Disorder had lower scores in Adolescent Affection-Communication (F = 8.201; p < 0.001), Father's Warmth (F = 3.459; p = 0.028), and Father's Acceptance/Involvement (F = 5.467; p = 0.003), and higher scores in Mother's Revoking Privileges (F = 4.277; p = 0.034) and Father's Indifference (F = 7.868; p = 0.002) than healthy participants. Male sex was a risk factor for Gaming Disorder (OR = 12.221; p = 0.004), while Adolescent Affection-Communication (OR = 0.908; p = 0.001) and Agreeableness (OR = 0.903; p = 0.022) were protective factors. Data modeling described the protective effect that Adolescent Affection-Communication had on Gaming Disorder, which was both directly (B = -0.20; p < 0.001) and indirectly mediated by Neuroticism (B = -0.20; p < 0.001), while Neuroticism itself was a risk factor for Gaming Disorder (B = 0.50; p < 0.001). These results reflect that Parental style with low affection and communication was directly and indirectly related to the Gaming Disorder, as well as male sex and personality trait of Neuroticism.

The effects of adverse childhood experiences on depression and suicidal behaviors are partially mediated by neuroticism: A subclinical manifestation of major depression.

Neuroticism, a personality trait, can predict major depressive disorder (MDD). The current study aims to determine whether a) neuroticism is a feature of the acute state of MDD, including suicidal behaviors (SB); and b) adverse childhood experiences (ACEs) are associated with neuroticism in MDD. This study included 133 participants, 67 healthy controls and 66 MDD patients, and assessed the Big 5 Inventory (BFI), ACEs using the ACE Questionnaire, and the phenome of depression using the Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory (BDI), The State-Trait Anxiety Inventory (STAI) and Columbia Suicide Severity Rating Scale (C-SSRS) scores to assess current SB. Neuroticism was significantly higher in MDD than controls, and it explained 64.9% of the variance in the depression phenome (a latent vector extracted from HAM-D, BDI, STAI, and current SB scores). The other BFI domains had much less (extraversion, agreeableness) or no effect (openness, conscientiousness). One latent vector could be extracted from the phenome, lifetime dysthymia, lifetime anxiety disorders and neuroticism scores. Neglect (physical and emotional) and abuse (physical, neglect and sexual) account for approximately 30% of the variance in this latent vector. Partial Least Squares analysis showed that the effects of neglect on the phenome were partially mediated by neuroticism, whereas the effects of abuse were completely mediated by neuroticism. Neuroticism (trait) and the MDD phenome (state) are both manifestations of the same latent core, with neuroticism being a subclinical manifestation of MDD.

Personality traits as mediators in the association between SIRT1 rs12415800 polymorphism and depressive symptoms among Chinese college students.

Previous research has linked polymorphisms in the SIRT1 gene to depressive symptoms, particularly in Chinese individuals. However, it is not clear how personality traits may contribute to this association. To explore the potential mediating effect of personality traits, we utilized a mediation model to examine the relationship between the SIRT1 rs12415800 polymorphism and depressive symptoms in 787 Chinese college students. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale, while personality traits were measured using the Big Five Inventory (BFI). Our analysis indicated a significant association between the SIRT1 rs12415800 polymorphism and depressive symptoms, with this relationship partially mediated by the personality traits of neuroticism and conscientiousness. Specifically, individuals who were heterozygous for the rs12415800 polymorphism and had higher levels of conscientiousness were less likely to experience depressive symptoms. Conversely, those who were homozygous for the rs12415800 polymorphism and had higher levels of neuroticism were more likely to experience depressive symptoms. Our results suggest that personality traits, particularly neuroticism and conscientiousness, may play a critical role in the association between the SIRT1 rs12415800 polymorphism and depressive symptoms among Chinese college students. These findings highlight the importance of considering both genetic factors and personality traits when exploring the etiology of depressive symptoms in this population.
