Assessment Of Personality Traits Research Articles

Personality and Risk of Arthritis in Six Longitudinal Samples.

Personality traits are broadly related to medical conditions, but there is limited research on the association with the risk of arthritis. This multicohort study examines the concurrent and prospective associations between personality traits and arthritis risk. Participants (N > 45,000) were mostly middle-aged and older adults from 6 established longitudinal cohorts. Baseline assessments of personality traits, covariates (age, sex, education, race, ethnicity, depressive symptoms, body mass index, and smoking), and arthritis diagnosis were obtained in each sample. Arthritis incidence was assessed over 8-20 years of follow-up. The meta-analyses identified an association between higher neuroticism and an increased risk of concurrent (odds ratio = 1.20, 95% confidence interval [CI] = 1.16-1.24; p < .001, I2 = 40.27) and incident (hazard ratio = 1.11, 95% CI = 1.08-1.14; p < .001, I2 = 0) arthritis and between higher conscientiousness and a decreased risk of concurrent (odds ratio = 0.88, 95% CI = 0.86-0.90; p < .001, I2 = 0) and incident (hazard ratio = 0.95, 95% CI = 0.92-0.98; p = .002, I2 = 41.27) arthritis. Higher extraversion was linked to lower risk of concurrent (odds ratio = 0.92, 95% CI = 0.88-0.96; p < .001, I2 = 76.09) and incident (hazard ratio = 0.97, 95% CI = 0.95-0.99; p = .018, I2 = 0) arthritis, and openness was related to lower risk of concurrent arthritis (odds ratio = 0.96, 95% CI = 0.93-0.99; p = .006, I2 = 35.86). Agreeableness was unrelated to arthritis. These associations were partially accounted for by depressive symptoms, body mass index, and smoking. There was no consistent evidence of moderation by age or sex. Findings from 6 samples point to low neuroticism and higher conscientiousness as factors that reduce the risk of arthritis.

Test as a Method of Psychology. Development History and Basic Requirements

Main problem: The article highlights the problem of tests as methods of psychology, the influence of validity and reliability on the results of psychological research. Purpose: Uncovering the significance of validity and reliability on psychological research results. Results and their significance: Testing is an important method in psychology, allowing measuring various aspects of the psyche and behavior of a person. The history of the development of tests in psychology goes back more than a century and began with the work of Francis Galton and Alfred Binet. Over time, the tests have become widely used in various fields such as education, personnel selection, clinical diagnosis and research. Basic requirements for tests include reliability (repeatability of results), validity (measurement accuracy), standardization (same test conditions) and objectivity (lack of subjectivity in assessment). Tests must be designed using psychometric principles to ensure accuracy and validity of results. Modern tests include a variety of measurement techniques, such as tests of personality, intelligence, aptitude, and professional skills. The use of tests in psychology requires professional training to correctly interpret the results and make valid conclusions. Testing as a method of psychology continues to evolve, and its role remains key in the study of the human psyche and behavior. Testing in psychology has a wide range of applications, including assessing personality traits, identifying psychological disorders, and predicting behavior and success in various areas of life. The development of computer-based tests and online platforms makes testing more efficient and convenient for researchers and participants. Modern tests increasingly take into account cultural differences and the diversity of individual characteristics, which contributes to more accurate and tailored assessments. It is important to remember that the use of tests requires ethics, confidentiality and compliance to ensure the reliability and validity of the data obtained.

Role of Personality Traits in Predicting Newlywed Intimacy and Relationship Quality

ABSTRACT While personality traits can predict couples’ behaviors in marital life, there are limited studies on the relationship between personality and marital relationships. This study aimed to examine the role of personality in predicting intimacy and the quality of marital relationships in newlywed couples. This cross-sectional study included 115 newlywed couples who participated in an online survey. Participants completed three questionnaires: the NEO Personality Inventory for assessing personality traits, the Intimacy Safety Questionnaire (ISQ) for measuring marital intimacy, and the Quality of Marriage Index (QMI) for evaluating marital quality. Marital intimacy was positively predicted by extraversion and conscientiousness in women and extraversion, conscientiousness, and openness in men. Relationship quality was negatively predicted by neuroticism in women while positively predicted by openness, agreeableness, and conscientiousness in men.

Latent Classes of Personality Traits and Their Relationship with Workplace Bullying among Acute and Critical Care Nurses

Objective. To identify the latent classes of personality traits among nurses in acute and critical care departments, as well as the relationship between latent classes of different personality traits and workplace bullying. Methods. A total of 245 nurses working in the acute and critical care department at a 3 A-grade hospital in Shandong Province, China, were recruited by convenient sampling. The Chinese Big Five Personality Inventory brief version was used to assess personality traits, and the Negative Acts Questionnaire was used to measure workplace bullying. Latent profile analysis was used to identify the latent classes of personality traits. Multiple linear regression analysis was used to examine the relationship between latent classes of personality traits and workplace bullying. Results. Four latent classes of personality traits among acute and critical care nurses were identified, namely, the negative group (49.0%), flexible group (16.0%), neurotic group (18.1%), and stable group (16.9%), respectively. Compared with the neurotic group, the negative group (B = −6.227, P&lt;0.05), stable group (B = −16.562, P&lt;0.001), and flexible group (B = −19.208, P&lt;0.001) experienced less workplace bullying. Conclusion. Our findings explore latent classes of personality traits among acute and critical care nurses, identify subgroups susceptible to workplace bullying, and suggest the development of appropriate interventions to reduce workplace bullying. Implications for Nursing Management. Hospital managers can identify nurses who are prone to workplace bullying based on their personality traits and provide them with psychological counseling services and psychological healing groups to help them establish good interpersonal relationships and maintain their mental and physical health.

Relationship Between Personality Traits and Perceived Pain After Photorefractive Keratectomy: A Cross-Sectional Study in Hamadan

Background: Photorefractive keratectomy (PRK) is a common procedure to correct refractive errors. However, postoperative pain is one of the most common drawbacks of PRK. Evidence shows that individual`s personality traits could impact postoperative perceived pain. Hence, this study aimed to investigate the severity of postoperative pain and personality traits after PRK.Materials and Methods: This cross-sectional study was performed on 300 patients who attended to Mahdieh Surgical Clinic (Hamadan, Iran) and underwent PRK. Persian version of the NEO Five-Factor Inventory (NEO-FFI) was applied to assess personality traits, and postoperative pain was measured using the visual analog scale (VAS) score.Results: The mean age of patients was 31.8 ±5.51 years, and most (68%) were female. The most common personality trait was neuroticism, and the mean refractive errors of the right and left eyes of the patients were 1.2±2.67 and 1.3±2.75, respectively. Regarding the VAS score, patients with neuroticism traits perceived the most severe postoperative pain (VAS=6±2.2). Also, the Pearson correlation test indicated a positive correlation between perceived pain and neuroticism personality traits (r=0.059, P˂0.001). In contrast, a significant negative correlation was observed between extraversion and conscientiousness with pain perception (r= -0.737 and r= -0.307, respectively).Conclusion: Our findings showed a positive and significant correlation between three personality traits and pain perception in these patients. Postoperative pain perception in patients undergoing PRK depends on the personality traits of these patients. Groups with less personality stability feel more pain than groups with stable personalities.

Measurement invariance of the Personality Inventory for DSM-5 across sex.

There has been an international movement towards dimensional models of personality disorders (PDs) in the last decades, which culminated in the publication of the Alternative Model of Personality Disorders (AMPD) in the Emerging Measures and Models section of the DSM-5. This model was accompanied by a APA-sanctioned Personality Inventory for DSM-5 (PID-5) for the assessment of the AMPD pathological personality traits. One major issue with the assessment of personality disorders pertains to sex differences, and measurement invariance across sex in assessment instruments for PDs is necessary in order to ensure non-biased evaluations and to make valid comparisons between men and women. This study aimed to provide more information on measurement invariance across sex for the PID-5, using both the original scoring approach provided by the authors of the instrument and the scoring approach suggested by the APA in the published version of the PID-5. This study was conducted with a sample of 2273 participants from the general Québec (Canada) adult population aged 18 to 90 years (M = 46.59; SD = 16.32; 51.8% women). The original scoring approach model showed good fit to data after freeing paths between certain traits and reached strict invariance. The APA scoring approach also showed good fit to data and reached strict invariance, but needed an adjustment (path freed between Emotional lability and Impulsivity in men) to reach scalar invariance. In line with previous research, the PID-5 is invariant across sex and the five-factor structure adjusts well to data. The APA scoring approach appears to attenuate the cross-loading problem observed with the original scoring approach. In light of these results, we recommend using the APA scoring approach to derive domain scores.

Changes in suicidal ideation during treatment among patients with major depressive disorder: A 6-month naturalistic follow-up study.

There is limited evidence regarding predictors of changes in suicidal ideation (SI) in patients with major depressive disorder (MDD). The objective of this study was to describe changes in SI over a 6-month period and identify their predictors from naturalistic observations of MDD patients. In the cross-sectional analysis, we examined 257 patients with MDD at the first-visit assessment. Among the patients, 119 who completed the 6-month assessment (completers) were included in the longitudinal analysis. For the evaluation of depressive symptoms, including SI, the Quick Inventory of Depressive Symptomatology-Japanese version was administered at both the first-visit and follow-up assessments. At baseline, we also administered the Japanese version of the Ten Item Personality Inventory to assess personality traits and the PRIME Screen-Revised to assess psychotic symptoms. In the cross-sectional analysis of first-visit patients, 36.2% (93/257) exhibited SI. Among completers, 14.3% (17/119) had prolonged SI. Among the completers with SI at the first-visit assessment, 38.6% (17/44) had SI at the follow-up assessment (prolonged SI). In linear regression models including all completers, prolonged SI was positively associated with endorsement of suspiciousness/persecutory ideas and negatively associated with higher age. More than one-third of completers who had SI at the first-visit assessment experienced prolonged SI (SI at follow-up). Our findings can help clinicians predict the course of MDD by identifying associated demographic and clinical characteristics.

Validation of the brief version of the Susceptibility to Persuasion-II scale and evaluation of measurement invariance across age and gender in the Canadian general population

Measurement tools that can assess personality traits rendering people more susceptible to engagement with and compliance in scams can help identify at-risk populations. The brief, 30-item version of the Susceptibility to Persuasion-II (StP–II–B) scale is a recently developed instrument for assessing 10 personality traits that play a role in scam compliance; however, psychometric evidence supporting the use of this scale is limited. This study aimed to validate the StP–II–B by examining its internal consistency reliability, factor structure, as well as age- and gender-related measurement invariance with a sample of 1287 Canadians aged 16 years and older. Confirmatory factor analysis supported a 10-factor structure identified in previous research. Good internal consistency reliability was obtained for each of the 10 subscales. This 10-factor structure was found to be invariant across age and gender at configural, metric, and scalar levels, suggesting that the StP–II–B was conceptualized in the same way across age and gender and that meaningful comparisons of factor scores could be made. Age and gender differences were found in most factors, with younger individuals and men scoring higher than older individuals and women. This study supports the use of the StP–II–B as a valid and reliable scale for measuring personality traits associated with scam compliance in the Canadian general population and offers insights into age and gender cohorts that may be at higher risk of scam victimization.

Associations between personality traits and depressive and anxiety symptoms among persons with spinal cord injury in first inpatient rehabilitation.

Retrospective analysis of medical records. To assess personality traits in persons with spinal cord injury (SCI) and compare these with the general population group. Moreover, to explore associations between personality traits and depressive and anxiety symptoms among persons with SCI in first inpatient rehabilitation. Specialized rehabilitation center in The Netherlands. Data were used from a routine psychological screening, administered in the first weeks of admission (N = 67). Measures included the Hospital Anxiety and Depression Scale and the Dutch Personality Questionnaire, which includes subscales measuring neuroticism, social inadequacy, rigidity, hostility, egoism, dominance, and self-esteem. Correlational and regression analyses were conducted. Mean age of the participants was 58 (SD 17) years. The majority (63%) were male, and had a low lesion (57%). The participants scored significantly higher on dominance and lower on social inadequacy, hostility, and egoism in comparison with the general population. In the bivariate regression analyses, high neuroticism (β = 0.42 and β = 0.53) and low self-esteem (β = -0.25 and β = -0.29) were significantly associated with increased depressive and anxiety symptoms. In the hierarchical regression analyses, only high neuroticism was significantly associated with increased depressive (β = 0.42, p < 0.05) and anxiety (β = 0.55, p < 0.001) symptoms. Personality traits are not the same between the SCI population and the general population. Assessment of personality traits early in inpatient rehabilitation can help to identify individuals at risk of mood problems and, thereby, facilitate interventions. Future research with a larger, representative SCI sample, is required to confirm these findings.

Assessing Personality Traits of School Administrators: A Big Five Perspective

This research aims to evaluate the personality characteristics of school administrators in terms of the big five personality theory characteristics. With research, in order to bring about positive changes in the education system. It aims to provide guidance on developing effective methods for the development and improvement of school administrators' personality traits. Five factor personality traits of school administrators were examined according to variables such as gender, professional seniority, seniority at school and education level. In this research, the survey model, one of the quantitative research models, was used. It was held in the 2022-2023 academic year in Sakarya province Hendek district with the participation of school principals and deputy principals working at all public primary, secondary and high school levels. 84 school administrators participated in the research. “Five Factor Personality Scale” was used in the research. As a result of the research, it was concluded that school administrators perceived themselves positively at the level of "partially agree" with their personality traits. According to the results of the research, the personality characteristics of school administrators do not differ according to gender variable, and in terms of professional seniority variable; It has been observed that school administrators with 20 years or more of seniority have higher "responsibilities". When looked at in terms of the seniority variable at school, it has been observed that school administrators with 7 years or more of seniority have higher "responsibility" levels than school administrators with 1-3 years and 4-6 years of seniority. When looked at in terms of the education level variable, no significant difference was found between personality traits and education level. It was concluded that there is a positive, moderate, and significant relationship between the big five personality sub-dimensions of school administrators: extraversion, responsibility, agreeableness and openness.

Psychometric Quality of the German HEXACO-60 Personality Inventory-Revised

Abstract: Striving for more valid personality judgments is desirable as more sound decisions can be expected with increasing measurement accuracy. In this study, the psychometric qualities of the German HEXACO-60 personality inventory are evaluated. Extending previous studies, we examined the third-person observer-report form in addition to the first-person rating format, which allowed us to examine the psychometric quality beyond self-reports, such as cross-rater agreement, rank-order stability, structural validity, and measurement invariance. Data from 3,046 self-raters (61% female; age range: 14–90) and ratings from 2,199 well-informed acquaintances (partners, friends, or relatives of the self-raters) were analyzed. Satisfying internal consistency, 2-year and 4-year rank-order stabilities, agreement among self- and informant-raters, and consensus among informant-raters were found. Moreover, the six-factor structure was confirmed in structural equation models that incorporated the perspectives of both self-raters and informant-raters. Finally, partial strict measurement invariance was demonstrated across rater perspectives. Previous validation of the German HEXACO-60 self-report form could thus be replicated and expanded by highlighting the psychometric soundness of the third-person observer-report form and the convergent as well as discriminant validity of HEXACO trait measures across rater perspectives. The informant perspective provides valid additional benefits for the assessment of personality traits within the HEXACO framework.

Individual factors and vection in younger and older adults: How sex, field dependence, personality, and visual attention do (or do not) affect illusory self-motion.

An important aspect to an immersive experience in Virtual Reality is vection, defined as the illusion of self-motion. Much of the literature to date has explored strategies to maximize vection through manipulations of the visual stimulus (e.g., increasing speed) or the experimental context (e.g., framing of the study instructions). However, the role of individual differences (e.g., age, biological sex) in vection susceptibility has received little attention. The objective of the current study was to investigate the influence of individual-difference factors on vection perception in younger and older adults. Forty-six younger adults (M age = 25.1) and 39 older adults (M age = 72.4) completed assessments of personality traits, field dependence, and visual attention prior to observing a moving visual stimulus aimed at inducing circular vection. Vection was measured using self-reports of onset latency, duration, and intensity. Results indicated that, in both age groups, females experienced longer-lasting vection compared to males. Additionally, the level of field dependence was related to vection intensity and duration in males but not in females. Variability in vection intensity was best explained by a mixture of biological, perceptual, cognitive, and personality variables. Taken together, these findings suggest that individual factors are important for understanding differences in vection susceptibility.

Association between dopamine receptor D2 Taq IA gene polymorphism (rs1800497) and personality traits.

This study aimed to find a potential association between the DRD2 Taq1A gene polymorphism (rs1800497 C32806T) and personality traits. In all, 249 youths were recruited for this study. The Short-form Revised Eysenck Personality Questionnaire was administered to assess personality traits. The participants were genotyped for the DRD2 Taq1A polymorphism using the polymerase chain reaction-restriction fragment length polymorphism method. Statistical analysis was carried out to find a possible association between the genotypes and aspects of personality traits assessed. The frequencies of the A1 and A2 alleles in our sampled population were 215 (43.2%) and 283 (56.8%), while the frequencies of A1A1, A1A2, and A2A2 were 67 (26.9%), 81 (32.5%), and 101 (40.6%), respectively. The study population was not in Hardy-Weinberg equilibrium (χ2 = 17.64, p < 0.001). The A2 allele was significantly associated with extraversion. Although this allele was also associated with neuroticism, psychoticism, and lie, the association was not significant. The A2 allele of the DRD2 Taq1A polymorphism was found to be more associated with extraversion, as measured by the Short-form Revised Eysenck Personality Questionnaire.

Dysfunctional eating attitudes and behaviors among French elite athletes: the impact of psychological characteristics and the sporting calendar.

Research on sport psychology suggests that athletes are at risk of developing dysfunctional eating attitudes and behaviors (DEAB), however the origins of these behaviors remain largely unexplored. The present study aims to identify factors (i.e., personality traits, anxiety levels, eating attitudes and behaviors, the internalization of sport thinness norms, and resilience) associated with the development of DEAB among female endurance athletes, in training and competition. A longitudinal follow-up study was conducted among 14 elite female athletes who were tested daily, weekly, and quarterly over 12 months in 2022, for a total of 545 measures. Participants completed questionnaires assessing personality traits, anxiety levels, eating attitudes and behaviors, the internalization of sport thinness norms, and resilience. Descriptive statistics were calculated for all study data, and odds ratios were conducted to compare the variance of psychological factors and sporting factors depending on the level of DEAB and the sport period. Significance was set at p < 0.05. Overall, 28% of our sample of athletes were identified with DEAB. Among those with DEAB, scores for agreeableness, anxiety, and competitive anxiety were significantly higher, while scores for resilience were significantly lower than those without DEAB. During the competitive season, scores for self-regulatory eating attitudes and the internalization of thinness norms were significantly higher than during the training period. Our results suggest a greater probability of DEAB among athletes who exhibit the trait of agreeableness, experience anxiety during competition, and lack resilience. The competitive season was also identified as a period conducive for developing DEAB compared with the training period. Based on these results our study suggests preventive measures that can be implemented with athletes displaying these traits, with a particular emphasis during the competitive phase.

Mapping personality traits to religious coping styles and struggle: Evidence from Malay Muslim undergraduates in Brunei

The current research explores religious struggle, aiming to assess personality traits as predictors and testing the mediating effects of religious coping styles. Using existing cross-sectional data, we used structural equation modeling to analyze data of 277 Malay Muslim undergraduates. The six-factor personality model HEXACO explained 14.2 % and 6.6 % of the variances for positive and negative religious coping styles respectively, with the addition of the two styles in the same model further explaining 19.5 % of the variances in religious struggle. Findings suggest significant relationships between various personality traits and religious coping styles, predictive of the level of religious struggle experienced by them. Extraversion and agreeableness positively predicted the use of positive religious coping style. Additionally, the same two traits with honesty-humility inversely predicted the use of negative religious coping style. Toward religious struggle, honesty-humility had a negative relation, contrasting with openness to experience having a positive relationship. Between the two religious coping styles, only positive style was observed to negatively predict religious struggle. Four mediation effects were observed. Findings provide valuable insights into the complex dynamics of religious struggle. These insights could inform future research and the development of targeted interventions to mitigate religious struggle.

An ecological study protocol for the multimodal investigation of the neurophysiological underpinnings of dyadic joint action.

A novel multimodal experimental setup and dyadic study protocol were designed to investigate the neurophysiological underpinnings of joint action through the synchronous acquisition of EEG, ECG, EMG, respiration and kinematic data from two individuals engaged in ecologic and naturalistic cooperative and competitive joint actions involving face-to-face real-time and real-space coordinated full body movements. Such studies are still missing because of difficulties encountered in recording reliable neurophysiological signals during gross body movements, in synchronizing multiple devices, and in defining suitable study protocols. The multimodal experimental setup includes the synchronous recording of EEG, ECG, EMG, respiration and kinematic signals of both individuals via two EEG amplifiers and a motion capture system that are synchronized via a single-board microcomputer and custom Python scripts. EEG is recorded using new dry sports electrode caps. The novel study protocol is designed to best exploit the multimodal data acquisitions. Table tennis is the dyadic motor task: it allows naturalistic and face-to-face interpersonal interactions, free in-time and in-space full body movement coordination, cooperative and competitive joint actions, and two task difficulty levels to mimic changing external conditions. Recording conditions-including minimum table tennis rally duration, sampling rate of kinematic data, total duration of neurophysiological recordings-were defined according to the requirements of a multilevel analytical approach including a neural level (hyperbrain functional connectivity, Graph Theoretical measures and Microstate analysis), a cognitive-behavioral level (integrated analysis of neural and kinematic data), and a social level (extending Network Physiology to neurophysiological data recorded from two interacting individuals). Four practical tests for table tennis skills were defined to select the study population, permitting to skill-match the dyad members and to form two groups of higher and lower skilled dyads to explore the influence of skill level on joint action performance. Psychometric instruments are included to assess personality traits and support interpretation of results. Studying joint action with our proposed protocol can advance the understanding of the neurophysiological mechanisms sustaining daily life joint actions and could help defining systems to predict cooperative or competitive behaviors before being overtly expressed, particularly useful in real-life contexts where social behavior is a main feature.

OCEAN-AI framework with EmoFormer cross-hemiface attention approach for personality traits assessment

Psychological and neurological studies earlier suggested that a personality type can be determined by the whole face as well as by its sides. This article discusses novel research using deep neural networks that address the features of both sides of the face (hemifaces) to assess the human’s Big Five personality traits (PT). For this, we have developed a real-time approach called EmoFormer with cross-hemiface attention. The novelty of the presented approach lies in the confirmation that each hemiface exhibits high predictive capabilities in terms of human’s PT distinction. Our approach is based on a novel mid-level emotional feature extractor for each hemiface and a cross-hemiface attention fusion strategy for hemiface feature aggregation. The consequent fusion of both hemifaces has outperformed the use of the whole face by the relative value of 3.6% in terms of Concordance Correlation Coefficient (0.634 vs. 0.612) on the ChaLearn First Impressions V2 corpus. The proposed approach has also outperformed all the existing state-of-the-art approaches for PT assessment based on the face modality. We have also analyzed the “best hemiface”, the one that predicts PT more accurately in terms of demographic characteristics (gender, ethnicity, and age). We have found that the best hemiface for two of the five PT (Openness to experience and Non-Neuroticism) is different depending on demographic characteristics. For the other three traits, the right hemiface is dominant for Extraversion, while the left one is more indicative of Conscientiousness and Agreeableness. These findings support previous psychological and neurological research. Besides, we provide an open-source framework referred to as OCEAN-AI that can be seamlessly integrated into expert systems with practical applications in various domains including healthcare, education, and human resources.
