Relationships between personality factors and DC/TMD Axis II scores of psychosocial impairment among patients with pain related temporomandibular disorders

This cross-sectional analytical study aimed to assess the relationship between personality factors and the DC/TMD Axis II scores of psychosocial impairment among patients with pain related temporomandibular disorders (TMD). 120 participants (60 females and 60 males) who were diagnosed with pain related TMD according to the Axis I DC/TMD protocol were recruited. The participants were requested to complete four tests including the NEO Five Factor Inventory (NEO-FFI) to assess personality factors and three Axis II DC/TMD tools; the Graded Chronic Pain Scale (GCPS) Version 2.0 to assess TMD pain intensity and pain-related disability, Patient Health Questionnaire-4 (PHQ-4) to assess psychological distress due to TMD pain, and Generalized Anxiety Disorder-7 (GAD-7) to assess patients’ stress reactivity. Results showed that 49.2% of the participants experienced high intensity of characteristic pain, 14.2% reported pain related disability more than 30 days (grade 3 disability days) and had disability scores of 70 or above (grade 3 disability scores), 16.7% demonstrated severe distress, and 18.3% reported severe anxiety due to TMD pain. Females scored higher on all these variables than males (P < .05). Multiple regression analyses indicated that higher extraversion scores, higher agreeableness scores and being a female were associated with higher intensity of characteristic pain (p < .05). Also, higher neuroticism and agreeableness scores were associated with more disability days (p < .05). In addition, higher agreeableness scores were associated with higher disability scores and disability point values (p < .05). Furthermore, lower neuroticism scores and being a female were associated with higher PHQ total scores, while being a female and having a lower level of education were associated with higher GAD total scores (p < .05). In conclusion, personality profiles and gender significantly impact the DC/TMD Axis II scores of psychosocial impairment among patients with pain related TMD.

Mediation effects of subjective social status and personality traits between childhood nurturing experiences and depressive symptoms in adult volunteers.

Various risk factors, such as childhood nurturing experiences and subjective social status, have been identified to be involved in the onset of depression. However, the mechanism of depression is not yet fully understood. In this study, we hypothesized that nurturing experienced in childhood affects subjective social status and current personality traits, which in turn influence depressive symptoms in adulthood, and verified this hypothesis through structural equation modeling. A questionnaire survey was conducted on 404 adults. Multiple regression analysis and structural equation modeling were conducted using demographic information and scores for the Patient Health Questionnaire-9, Parental Bonding Instrument, and NEO Five-Factor Inventory. Subjective social status was found to mediate the association between nurturing experiences and neuroticism (0.029 for Overprotection and -0.034 for Care). On the other hand, neuroticism was found to mediate the association between subjective social status and depressive symptoms (-0.097 in Care model and -0.103 in Overprotection model), as well as the association between nurturing experiences and depressive symptoms (0.144 for Overprotection and -0.134 for Care). Furthermore, it was also shown that complex paths, in which the association of nurturing experiences with depressive symptoms was mediated by two factors, namely, subjective social status and neuroticism, were statistically significant as indirect effects (0.016 for Overprotection and -0.018 for Care). In this study, we clarified that nurturing experienced in childhood affects neuroticism in adulthood, which is mediated by subjective social status, and furthermore, the effects of nurturing on neuroticism lead to varying levels of depressive symptoms in adulthood. The mediation effects demonstrated in the present study may contribute towards unraveling the causes of depression and developing effective treatments for depressive symptoms.

Multi-modal EEG NEO-FFI with Trained Attention Layer (MENTAL) for mental disorder prediction.

Early detection and accurate diagnosis of mental disorders is difficult due to the complexity of the diagnostic process, resulting in conditions being left undiagnosed or misdiagnosed. Previous studies have demonstrated that features of Electroencephalogram (EEG) data, such as Power Spectral Density (PSD), are useful biomarkers for indicating the onset of various mental disorders. Existing models using EEG data are typically trained to distinguish between healthy and afflicted individuals, and they are unable to distinguish between individuals with different disorders. We propose MENTAL (Multi-modal EEG NEO-FFI with Trained Attention Layer) to predict an individual's mental state using both EEG and Neo-Five Factor Inventory (NEO-FFI) personality data. We include an attention layer that captures the interactions between personality traits and PSD features, and emphasizes the important PSD features. MENTAL features a Recurrent Neural Network (RNN) to model the temporal nature of EEG data. We train our model with the Two Decades Brainclinics Research Archive for Insights in Neuroscience (TDBRAIN) dataset, which consists of 1274 healthy and psychiatric individuals including over 30 different diagnoses. MENTAL is able to achieve 93.3% accuracy when trained to classify between healthy individuals and those with ADHD. When trained to identify individuals with ADHD from among 33 disorder classes, MENTAL improves accuracy from 70.5 to 81.7%. MENTAL also demonstrates over 20% improvement in predictive accuracy when trained for MDD prediction. For the multi-class classification task of three classes, MENTAL improves accuracy by 4%, and for five classes, by nearly 8%. MENTAL is the first multi-modal model that utilizes both EEG and NEO-FFI data for the task of mental disorder prediction. We are one of the first groups to utilize TDBRAIN for automated disorder classification. MENTAL is accessible and cost-effective, as EEG is more affordable than other neuroimaging methods such as MRI, and the NEO-FFI is a self- reported survey. Our model can lead to acceptance and support for individuals living with mental health challenges and improve quality of life in our society.

Factors Influencing Special Education Career Choices: Interplay of Personality Traits and Identity Statuses

&lt;p style="text-align:justify"&gt;Recent research has identified factors influencing the choice of a special education career; however, it has not thoroughly examined their connection with personality traits and identity status. Thus, the present study was designed to explore how different personality traits and identity statuses correlate with the motives and perceptions associated with the choice to teach in special education. The study involved 209 pre-service special education teachers. The NEO-Five Factor Inventory was used to measure the Big 5 personality traits. The Ego Identity Process Questionnaire assessed identity commitment and exploration. The Factors Influencing Teaching Choice Scale was used to evaluate motivations and perceptions about teaching. Regarding the factors that influenced the decision to pursue a career in special education, intrinsic value, shaping children’s future, social equity, making social contributions, working with children, task demands, and job satisfaction were highly rated. Additionally, extraversion, openness to experience, conscientiousness, and identity statuses were identified as positive predictors for certain factors influencing the choice of a teaching career in special education. Finally, the study identified two distinct groups of students: "Identity Achievers" characterized by high positive personality traits, and identity commitment, and "Identity Explorers" characterized by lower positive personality traits and higher identity exploration. Differences were observed between the groups in their motives and perceptions concerning teaching in special education. In conclusion, this study highlights the relationships between personality, identity status, and career decision factors, offering insights into the factors that influence this critical career decision among future special educators. Directions for future research are discussed.&lt;/p&gt;

Exploring trait differences in neurofeedback learners: a single-session sham-controlled pilot study

AbstractNeurofeedback (NF) is a form of biofeedback that involves individuals monitoring and shifting brain activity towards a desired direction. The objective of this study was to investigate whether there are differences between NF learners and non-learners on psychometric traits such as the NEO PI-R personality factors, self-regulation questionnaire (SRQ) and the need for cognition scale (NFC). A total of 34 participants were randomly allocated to a single-blind randomised sham-controlled protocol 3-arm study of single-session theta NF. Twelve participants were administered a spatially defined frontal-midline theta (FM-theta) group, 11 to a functionally defined medial temporal/parietal lobe (MTL-theta) group and 11 allocated to a yoked sham NF group. The baseline session included screening of participants, trait-based behavioural measures (SRQ, NFC and NEO PI-R) and the completion of cognitive tasks with electroencephalography (EEG) recording to determine individualised peak theta activity for NF training. NF learners and non-learners were evaluated using changes in absolute theta power and the percentage of time spent above threshold using Spearman’s correlation coefficient from a total of 30-minutes of NF exposure. Significant differences in psychometric traits between NF learners and non-learners differed depending on learning metrics. Results indicated that NF learners reported higher SRQ total scores, SRQ decision making, SRQ goal setting subfactors and NEO PI-R conscientiousness, but were significantly lower in NEO PI-R extraversion compared to non-learners. This study demonstrates that learning outcomes vary based on the metrics used and emphasises the importance of selecting appropriate learning metrics and further examination of learning within sham NF training.

Longitudinal interactions between maternal depression symptoms and familial stressful life events on child anxiety symptoms at 5years of age.

In the current study we identified salient parental factors for child anxiety symptoms by considering the role of stressful life events, maternal anxiety symptoms, maternal depressive symptoms, and maternal neuroticism. Families (N=399) in an urban area in the United States were participants in a longitudinal study beginning in infancy. Mothers completed measures of stressful life events (Revised Life Events Questionnaire at all visits), maternal anxiety and depressive symptoms (State-Trait Anxiety Inventory and Beck Depression Inventory, respectively, at infancy between 5 and 12months, at 2years, and at 3years), maternal neuroticism (NEO Five-Factor Inventory at infancy), and child anxiety symptoms (Child Behavior Checklist 1.5-5 at 5years). Linear mixed models (LMMs) were used in analyses. Maternal depressive symptoms from infancy through 3years were associated with child anxiety symptoms; other main effects modeled (stressful life events, maternal anxiety symptoms, maternal neuroticism) were not associated with child anxiety symptoms. There was a significant interaction effect between stressful life events and maternal depression. Stressful events from infancy through 5years of age increased risk for child anxiety symptoms at 5years if the child's mother had a mild mood disturbance or depression, but not for children with non-depressed mothers.

Effect of hormone therapy on personality traits: preliminary evidence in older men and women.

Findings concerning the effects of hormone therapy (HT) on cognition and dementia are mixed, with some trials suggesting increased harm at older ages. Personality, like cognition, changes with dementia, but no clinical trials to date have examined the effects of HT on personality traits. This study aimed to determine the effects of HT on personality traits in older men and women. Secondary data analysis was performed from randomized, double-blind, placebo-controlled cross-over studies of menopausal HT in women and testosterone therapy (TT) in men. Participants were community-dwelling cognitively normal adults (mean age = 75.2 years), including 29 men and 22 women. Three months of hormone intervention (for women, 0.625 mg/day conjugated equine estrogen with or without 2.5 mg/day medroxyprogesterone acetate; for men, 200 mg intramuscular testosterone enanthate every 2 weeks) were crossed over with 3 months of identical placebo with a 3-month washout between intervention phases. The main outcome measure was neuroticism and conscientiousness personality domains and facets assessed with the Revised NEO Personality Inventory (NEO-PI-R) after the active and placebo intervention phases. In linear mixed-effect models, HT in women decreased conscientiousness (p < 0.01) and the conscientiousness facet of achievement striving (p < 0.01), and increased vulnerability, a facet of neuroticism (p < 0.05). Testosterone in men decreased conscientiousness (p < 0.05) and the conscientiousness facet of dutifulness (p < 0.05), and increased vulnerability (p < 0.05). In a preliminary study of healthy older adults, HT and TT formulations produced adverse changes in vulnerability and conscientiousness facets that parallel personality changes in dementia.

B - 14 NEO Personality Inventory-Revised (NEO-PI-R) Domains Compared across BSNIP-2 Biotypes for Psychosis Spectrum Disorders

Abstract Objective The NEO Personality Inventory-Revised (NEO-PI-R) is commonly used to assess the Big Five personality traits: Neuroticism (N), Extroversion (E), Openness (O), Conscientiousness (C), and Agreeableness (A). This study compared NEO-PI-R personality factor composite scores across novel biological and neuropsychological characterizations of psychotic spectrum disorders (“biotypes”) derived by the Bipolar Schizophrenia Network for Intermediate Phenotypes (B-SNIP) consortium. Understanding personality patterns in more specific characterizations of psychotic spectrum disorders may shed light on behavioral patterns, including help-seeking in psychosis spectrum disorders. Methods Participants were 1086 individuals with a psychosis spectrum disorder grouped by biotype rather than DSM diagnosis who completed the NEO-PI-R. Results One-way ANOVAs were used to assess potential biotype group differences regarding NEO-PI-R traits. Post-hoc comparisons revealed that healthy controls endorsed more extroverted, agreeable, conscientious and less neurotic personality traits compared to the biotypes collectively. Traits of openness differentiated biotypes such that Biotype 3 endorsed more openness than Biotypes 1, 2 and Healthy Controls. Conclusions In addition to normal range cognitive abilities, less symptomatology, and fewer electrophysiological/imaging abnormalities, the present findings indicate that the Biotype 3 group endorsed more openness than the other patient groups. Like the Biotype 1 and 2 groups, internalizing symptomatology was present in the Biotype 3 group (less agreeableness, more neuroticism, less conscientiousness). Increased executive functioning, flexibility, problem-solving, and/or self-monitoring could be important factors contributing to the greater openness of the Biotype 3 group.

Exploring the impact of stuttering simulation-based learning and personality traits on clinical self-efficacy and professional interest among speech-language pathology students.

Research suggests that participating in a stuttering simulation-based learning (SBL) program could help speech-language pathology (SLP) students feel more at ease, less nervous and more capable while interacting with people who stutter. Personality traits may influence SLP students' self-efficacy beliefs as well as their level of interest in working with clients who stutter. In particular, we suggest that the combination of low neuroticism and high extraversion, previously linked with a more outgoing, emotionally stable and social personality, may enhance self-efficacy. To examine the impact of participating in a stuttering SBL program on clinical self-efficacy (CSE) in managing stuttering therapy among SLP students, as well as its influence on their interest in working with fluency disorders and their associations with personality dimensions. The study also evaluated satisfaction with the SBL experience. SLP students (n = 49) underwent a fluency disorders academic course, self-reported on CSE, and had an interest in working in the field of stuttering and NEO-Five-Factor Inventory (NEO-FFI). Post-stuttering SBL program participation, CSE and level of interest in practice of stuttering were reassessed. Satisfaction with the simulation was also gauged. Students interested in working with fluency disorders scored lower in neuroticism and higher in extraversion than their uninterested counterparts. Before the SBL activity, interest ratings were negatively correlated with neuroticism and positively correlated with extraversion. Pre-SBL neuroticism was negatively correlated with CSE. Following the SBL activity, increased CSE and interest in working with fluency disorders were evident, indicating robust and medium effects of the simulation on those indices, respectively. Post-SBL neuroticism was also negatively correlated with CSE. Overall, participants reported high satisfaction with the SBL experience. The study suggests SBL is an effective tool for enhancing motivation to work with fluency disorders. Consideration of personality traits and professional interests in designing educational interventions for SLP students, along with tailoring approaches to individual differences, may enhance learning outcomes. The study also highlights the need to differentiate between CSE and objectively assessed clinical competence and the fact that professional development is influenced by various factors. Nonetheless, the positive correlations between personality traits, CSE and satisfaction emphasize the potential of SBL programs in shaping not only clinical skills but also the attitudes and preferences of future SLPs. What is already known on this subject SLPs in the field of stuttering therapy reportedly experience low levels of comfort and professional confidence, possibly due to insufficient clinical experience. According to earlier research, taking part in SBL programs may elevate the CSE of SLP students and help them feel more confident about treating people with stuttering. What this study adds to the existing knowledge In addition to showing the beneficial effects of an SBL activity on SLP students' self-efficacy and interest in working in stuttering therapy, our research shows a significant relationship between personality traits and CSE. Specifically, the combination of high extraversion and low neuroticism was found to be associated with higher CSE and higher levels of satisfaction from the SBL. What are the potential or actual clinical implications of this work? The study shows that SBL is an effective tool for enhancing motivation to work with fluency disorders. Overall, students who exhibit high extraversion and low neuroticism show higher levels of CSE, greater motivation in stuttering treatment, and higher levels of SBL stratification. Development of future SBL activities and other educational interventions should take into consideration such personality traits, to enhance learning outcomes.

Analysis of the moderator effect of overstimulation on the relationships between indicators of health-related quality of life, extraversion and maladaptive coping strategies in people with sensory processing sensitivity

People with sensory processing sensitivity (SPS), when overstimulated, feel overwhelmed, stressed, and in need of social withdrawal, rest, and reestablishing balance in the nervous system. This study focuses on analyzing the moderator effect of overstimulation on health-related quality of life (mental health, vitality, and body pain), extraversion, and maladaptive coping strategies in people with SPS. Participants (N = 10,520 adults) completed the Spanish versions of the High Sensitivity Person Scale (HSPS-S), Short Form Health Survey (SF-36), NEO Five-Factor Inventory (NEO-FFI) and Coping Strategies Inventory (CSI). Participants with high overstimulation levels were observed to have a worse quality of life related to health, greater introversion, and a tendency to use more maladaptive coping strategies. Furthermore, two of the health-related quality of life indicators, mental health and vitality, occupy a central position in the relationships between variables; there was a negative relationship between mental health and active maladaptive coping strategies, as well as between extraversion and nonactive maladaptive coping strategies. Lastly, the level of overstimulation was not identified as an indicator that differentially influences its relationship with the study variables. These findings demonstrate the need to use prevention and clinical intervention programs that address mental health and vitality, as well as introversion and the use of maladaptive coping strategies in people with high sensitivity.

The Role of Personality Traits, Cognitive Performances, and Perceived Social Support on Job Satisfaction Among Individuals with Chronic Psychiatric Disorders

Background: This study was conducted due to the importance of job satisfaction in chronic psychiatric patients and the lack of sufficient information about the associated variables. Objectives: The study aimed to assess the role of personality traits, cognitive performances, and perceived social support on job satisfaction among individuals with chronic psychiatric disorders employed in supportive-productive workshops in Semnan. Methods: This cross-sectional study was conducted using a quantitative and descriptive-correlational regression method. It included 152 individuals (both male and female) with chronic psychiatric disorders employed in supportive-productive workshops in Semnan city in 2022. Participants were randomly selected through a lottery method. Data were gathered using the NEO Five-Factor Inventory by Costa and McCrae (1985), the Field and Roth Job Satisfaction questionnaire (1951), Zimet's (1988) scale for perceived social support, and the Montreal Cognitive Assessment (1996). Data analysis was performed using regression analysis with SPSS version 24. Results: The regression analysis illustrated that although neuroticism, agreeableness, extraversion, conscientiousness, perceived social support, and cognitive performances had a significant predictive role on job satisfaction among patients with chronic psychiatric disorders, perceived social support and conscientiousness had the most significant effect, while cognitive performances had the least significant effect on predicting job satisfaction (P &lt; 0.05). Conclusions: It is recommended that authorities pay special attention to the perceived social support from society and family, as well as cognitive rehabilitation focusing on attention and concentration for individuals with chronic psychiatric disorders.

Big five personality traits and resilience as predictors for self-isolation adherence during COVID-19 pandemic

Background &amp; Aim: Results of previous studies on the role of personality traits and resilience in explaining health-oriented behaviors such as social/physical distance and self-isolation were inconsistent. The present study was conducted to determine the role of the five big personality traits and resilience in adherence to self-isolation during the COVID-19 pandemic. Methods &amp; Materials: A prospective longitudinal cohort study tracked 112 healthcare providers who tested positive for SARS-CoV-2. Using GPS data from their cell phones, researchers assessed self-isolation adherence over 14 days. Participants completed NEO-Five-Factor Inventory (NEO-FFI) and Connor–Davidson Resilience Scale (CD-RISC) questionnaires. Results: Sixty-one (58.7%) of the subjects violated their self-isolation, and 43 (41.3%) did not violate it during the 14 days after PCR positivity for COVID-19. After adjustment for potential confounders, results showed that only two of the five big personality traits included, conscientiousness (AOR=1.37; 95%CI: 1.15–1.63) and neuroticism (AOR=0.85; 95%CI: 0.74–0.98), were significantly related to the self-isolation adherence. This means a one-unit increase in conscientiousness is associated with 37% higher odds of self-isolation adherence, while a one-unit increase in neuroticism reduces self-isolation adherence by 15%. Resilience was the main predictor for self-isolation adherence in which a one-unit increase in resilience score, the odds of adherence to self-isolation significantly increased by 18% (AOR=1.18, 95%CI: 1.07–1.30) (P&lt;0.001). Conclusion: The study suggests that fostering conscientiousness and resilience among individuals may enhance self-isolation commitment during pandemics. Further research is needed to explore the influence of agreeableness, extraversion, and openness to experience on self-isolation adherence.

Comparing five-factor personality traits and psychological distress between dysphonic patients and individuals with vocally healthy voices.

It was reported that voice can carry information about personality and psychological distress. In the current study, the relationship between five-factor personality traits and psychological distress with voice was enlightened from diverse aspects. A total of 119 participants (55 with and 64 without dysphonia) sustained vowels /a/ and /i/, read six standard sentences, and answered a question. Three raters auditory-perceptually evaluated the vocal samples using the Persian version of CAPE-V. The participants were distributed into four groups (vocally healthy, mild, moderate, and severe dysphonia). They completed two questionnaires: NEO Five-Factor Inventory (NEO-FFI) and Depression, Anxiety, and Stress Scale-21. Results showed that the conscientiousness (U=1146.500, z=-3.27, p=.001) in the dysphonia group was significantly less than the vocally healthy group. Depression (U=1381.000, z=-2.03, p=.042) and anxiety (U=1181.000, z=-3.10, p=.002) in the dysphonia group were significantly higher than in the vocally healthy group. In comparing different abnormal overall voice qualities, the mild dysphonia group revealed significantly lower conscientiousness (p=.001) and significantly higher anxiety (p=.002) relative to the vocally healthy group. Findings indicated that the conscientiousness trait could play an influential role in persons with dysphonia and its psychological status. The voice care team should consider conscientiousness and psychological distress during the assessment and treatment of dysphonic patients.

Burnout and personality factors among surgical area nurses: a cross sectional multicentre study.

To determine levels of burnout among surgical area nurses in Andalusia (Spain), to identify the phase of burnout in each participant and to consider its relationship with sociodemographic, occupational variables and personality factors considered. Data were collected by means of questionary. All nurses working in the surgical area on the date of data collection participated in the study. Sociodemographic and related to work variables were addressed in the questionnaire. Symptoms of anxiety and depression were measured using the Educational-Clinical Questionnaire: Anxiety and Depression (CECAD). Psychological personality variables were assessed using the NEO Five-Factor Inventory (NEO-FFI), adapted for a Spanish population. Burnout was measured using the Maslach Burnout Inventory (MBI). Multicentre, cross-sectional, quantitative study carried out from August to October 2021. Descriptive analysis, Student's t-test for independent samples, Pearson's correlation and multiple linear regression were performed with SPSS 25.0. The study sample consisted of 214 surgical area nurses at 23 hospitals in Andalusia (Spain). Sociodemographic, occupational and personality variables were studied using the Maslach Burnout Inventory, the NEO Five-Factor Inventory (NEO-FFI) and the Educational-Clinical Questionnaire: Anxiety and Depression. The STROBE statement guidelines were applied. 29.4% of the nurses in the sample presented high levels of emotional exhaustion, 25.7% suffered from depersonalization and 28% had low levels of personal accomplishment. These three dimensions were significantly correlated with the NEO-FFI subscales (neuroticism, agreeableness, openness, conscientiousness and extraversion), and with all the anxiety and depression items considered. Agreeableness was a statistically significant predictor (p < 0.001) for all three dimensions of burnout. Nurses in the surgical area present high levels of Burnout. There is evidence that relates Burnout to personality factors and socio-demographic variables.

Exploring the Relation Between Extroversion, Neuroticism and Resilience among Young Adults

The purpose of this study was to examine the relationship between extroversion and neuroticism traits along with gender and how it influences resilience among young adults. Data was collected from a sample of 150 participants, where there were 75 males and 75 females within the age group of 18-26. For this purpose, the NEO Five factor inventory(NEO-FFI) and the abbreviated version of the Nicholson McBride Resilience Questionnaire were administered.The results indicates that there is a mild to moderate positive correlation between extroversion and resilience (correlation coefficient = 0.39, p-value = 0.00) and also between gender and resilience (correlation coefficient = 0.25, p = 0.00), while there is a mild negative correlation between neuroticism and resilience (correlation coefficient=-0.33,p-value=0.00). Multiple linear regression highlights a statistically significant relationship between extroversion and resilience (B = 0.035, p = 0.00), a significant negative relationship between neuroticism and resilience (B = -0.22, p = 0.006), and a significant difference in resilience scores between genders,which can be calculated as resilience = 35.982 + 0.357 (Extraversion) − 0.228 (Neuroticism) + 2.282 (Gender), where males showed higher gender in relation to female participants.

HINT1 Gene Polymorphisms, Smoking Behaviour, and Personality Traits: A Haplotype Case-Control Study.

The factors influencing the development and maintenance of nicotine dependence are numerous and complex. Recent studies indicate that smokers exhibit distinct genetic predispositions to nicotine dependence. We aimed to analyse (1) the association between rs2551038 and cigarette smoking, (2) the association of between the rs3864236-rs2526303-rs2551038 haplotype and cigarette smoking, and (3) the personality traits measured by the NEO Five-Factor Inventory in cigarette users and never-smokers. No significant differences were present in the frequency of rs2551038 genotypes and alleles in the studied cigarette users compared to the control group. Cigarette users, compared to the control group, had higher scores on the NEO-FFI Extraversion scale (p = 0.0011), and lower scores were obtained by the cigarette users for the NEO-FFI Openness (p = 0.0060), Agreeability (p ≤ 0.000), and Conscientiousness (p ≤ 0.000) scales. There was a significant positive Pearson's linear correlation between the age and the Fagestrom test (r = 0.346; p < 0.0001) and the NEO-FFI Openness scale (r = 0.180; p < 0.0001) in the group of cigarette users. We observed significant linkage disequilibrium between rs2526303 and rs3864236 (D' = 0.3581; p < 2.2204 × 10-16) and between rs2526303 and rs2551038 (D' = 0.9993; p < 2.2204 × 10-16) in the tested sample. The sex-stratified haplotype analysis revealed that in the group of male never-smokers, the GTC haplotype was significantly more frequent than in the group of cigarette users (38% vs. 22%; p = 0.0039). The presented study reveals significant differences in personality trait scores between cases and controls. Moreover, the sex-stratified analysis showed significant differences in haplotype distribution. These results underscore the interplay between genetic predisposition, sex, and personality in nicotine-using individuals.

Examining the Effect of Birth Order on Neuroticism and Extraversion among Adolescents and Young Adults

This study investigates the influence of birth order on personality traits, specifically Neuroticism and Extraversion, among adolescents and young adults. A total of 120 participants aged between 14-25 years completed a survey distribution via Google Forms. The sample was evenly split into two groups: Elder children (First-born) and Younger children (Last-born), each comprising 60 individuals. The personality traits were assessed using Neuroticism and extraversion subscales of the Neo-Five Factor Inventory (NEO-FFI, Costa &amp; McCrae, 1992). Data analysis involved the use of a two-sample Kolmogorov-Smirnov (K-S) test to compare the distribution of Neuroticism and Extraversion scores between the two birth groups. The results indicate that there is no statistically significant difference in the distribution of Neuroticism and Extraversion traits between elder and younger children. These findings contribute to understanding how birth order is not the sole influence on neuroticism and extraversion among adolescents and young adults.

Evaluating the Impact of Obsessive-Compulsive Symptoms and Personality Types on Perinatal Depressive Symptoms.

Perinatal depression (PPD) presents a significant public health concern, often influenced by psychological and personality factors. This study investigated the impact of personality traits, particularly neuroticism, and obsessive-compulsive disorder (OCD) symptoms on the severity of PPD. The primary aim was to quantify the contributions of these factors to the risk and severity of PPD to enhance early intervention strategies. A total of 47 pregnant women with depressive symptoms per DSM-5 criteria at "Pius Brinzeu" County Emergency Hospital in Timisoara, Romania, were enrolled in this cross-sectional study, as well as 49 women without depressive symptoms as controls. Personality traits were assessed using the NEO Five-Factor Inventory (NEO-FFI), and OCD symptoms were measured using the Obsessive-Compulsive Inventory (OCI). Depression severity was evaluated using the Edinburgh Postnatal Depression Scale (EPDS). This set of questionnaires were administered antepartum and postpartum. The logistic regression analysis highlighted neuroticism as a significant predictor of PPD severity, with an increase in neuroticism associated with a higher risk of PPD (coefficient = 0.24, p < 0.001). Conversely, openness showed a protective effect (coefficient = -0.13, p = 0.009). Higher OCD symptomatology, particularly ordering and hoarding, were linked with increased depression scores. Specifically, the total OCI score significantly predicted the EPDS score (coefficient = 0.03, p = 0.003). Furthermore, significant increases in EPDS anxiety and depression scores were observed in the perinatal period, indicating worsening of symptoms (anxiety coefficient = 0.51; p < 0.001). The findings suggest that personality traits like neuroticism and OCD symptoms significantly contribute to the severity of PPD. Interventions targeting these specific traits could potentially mitigate the risk and severity of perinatal depression, underscoring the need for personalized treatment plans that consider these psychological dimensions.

The relationship between personality and cognition in older adults with and without early-onset depression.

It is well established that personality traits impact cognition, as certain personality factors are associated with performance in specific cognitive domains. However, the findings on the relationships between the Big Five traits and cognition are mixed. Additionally, few studies have explored these relationships in older adults with a history of depression. The present study aimed to (a) evaluate the impact of the Big Five personality traits in older adults with and without a lifetime history of depression; and (b) test the hypotheses that higher trait neuroticism would correlate negatively with cognitive performance, while openness to experience would correlate positively with cognition. The sample consisted of 138 participants between the ages of 55 and 78 (M = 65.56, SD = 6.36). Sixty-two participants met criteria for current or remitted Major Depressive Disorder, while 76 had no history of depression or other mental health disorders. Participants underwent comprehensive neuropsychological testing. Personality was assessed using the NEO Personality Inventory-Revised (NEO-PI-R), while depression status was determined using the Structured Clinical Interview for DSM-5 (SCID-5). Following a series of Pearson correlations of cognitive variables and the five personality factors, linear regression models were estimated for each significant correlation. Demographic variables (i.e., age, education and sex) were entered in block 1, depression status (never vs. ever) was entered in block 2, and the personality factor score, or sub-facet was entered in block 3. Neuroticism was not associated with cognitive performance on any outcome measure. The facets Openness to Feelings and Openness to Values were positively related to phonemic fluency. Further Openness to Values was positively related to cognitive flexibility. Our results suggest that older people who are (a) more capable of identifying and understanding their feelings and the feelings of others, and (b) who are more willing to re-examine social, political, and religious values perform stronger on tasks measuring verbal fluency and cognitive flexibility, which are aspects of executive functioning. Interventions that aim to enhance open mindedness in older adults may have a parallel impact on improving executive functioning, though this would need to be examined prospectively.

P-489 Examining information, willingness to donate and beliefs regarding gamete donation among people of reproductive age

Abstract Study question Which beliefs, motives and psychosocial characteristics distinguish people who are willing to donate their gametes from those who are not? Summary answer Willingness to donate does not differ between men and women, but there are differences in beliefs surrounding its risks, motivations and psychological characteristics. What is known already Previous studies have examined the main psychological characteristics of donors and their motivation to donate. Literature shows that donation is motivated by altruism, with donors being autonomous, self-confident, self-acceptant, and goal-orientated people, guided by meaningful values. Gender differences showed that egg donors often have close contact with infertility situations and motherhood and would like to provide this joy to other women. Sperm donors are more motivated by curiosity about their own fertility and want to spread their “good” genes. However, here is still much to know about what distinguish those who are willing to donate from those who are not. Study design, size, duration This is a cross-sectional study. Data was collected through an online questionnaire, which was disseminated using social media. Inclusion criteria were being adult, within a reproductive age range (between 18 and 35 years old), and fluent in Portuguese. Participants/materials, setting, methods A total of 405 participants completed the survey (305 women and 99 men). The questionnaire included sociodemographic data, beliefs towards gamete donation, reasons that might impact the likelihood of donating, and psychological characteristics through self-administered instruments: Experiences in Close Relationships (ECR), Self-Compassion Scale (SELFCS), Self-Report Altruism Scale (SRAS), NEO Five-Factor Inventory (NEO-FFI). Independent t-test was performed to compare men and women and participants willing or not to donate gametes. Main results and the role of chance Women were 22.86 (±.23) years old and men 24.34 (±.43). A total of 24.2% of participants were willing to donate gametes. There were no gender differences regarding willingness. Significantly more women than men believed that donating gametes might imply psychological risks (p=.001). There were gender differences in motivations to donate. Women were more likely to donate if they could receive fertility counselling (p=.005) and information about infertility (p=.037), and if they could talk with other donors (p&amp;lt;.001) than man. Among women, those willing to donate believed donating would not cause psychological damage (p=.004), would be supported by their social network (p =.006) and would not be criticized by family and friends if they did so (p=.011) compared to those not willing. Psychological differences revealed that women willing to donate presented higher levels of common humanity (p=.003), self-kindness (p=.046), were more altruistic (p&amp;lt;.001) and extroverted (p=.027) than those who were not. No differences were found regarding their attachment orientation. Among men, the only differences distinguishing those who considered donating sperm and those who did not was their altruism levels (p=.047). No differences were found regarding their beliefs towards gamete donation, perceived support regarding the decision, attachment style, self-compassion, and personality traits. Limitations, reasons for caution This study included a convenience sample, and participants lacked adequate information about the legal context and implications of donating gametes in Portugal. The sample size of participants considering donating was small, which may affect our conclusion. Wider implications of the findings Women who consider donating seem to present more salient psychological characteristics than men. Stigma and misinformation might prevent women from considering donating eggs. The possibility of receiving fertility counselling and share their experiences with other donors are valued in the process, which should be considered when recruiting donors.
