The Big-Five personality factors, cognitive ability, health, and social-demographic indicators as independent predictors of self-efficacy: A longitudinal study.

This study set out to examine to what extent a set of psychological, health and socio-demographic factors are associated with self-efficacy (SE) in a large sample of over 12,000 participants over a two-year period. We were interested in the correlates of self-efficacy (criterion variable) with gender, age, education and occupation, the Big-Five personality factors and cognitive ability, as well as mental and physical health (predictor variables). Regression analyses showed that four of the Big-Five personality factors (extraversion, neuroticism, conscientiousness, and openness), cognitive ability, mental and physical health, gender, education and occupation were all significant and independent predictors of self-efficacy, accounting for 23% of the variance of the outcome variable. Personality variables, particularly Neuroticism and Conscientiousness, were the most powerful predictors of SE two years later. The implications for encouraging SE in individuals are discussed.

Personality moderators of the cross-sectional relationship between job demands and both burnout and work engagement in judges: The boosting effects of conscientiousness and introversion.

The central question of this study is whether buffering, boosting and exacerbating effects of the Big Five personality factors extraversion, openness to experience, agreeableness, conscientiousness and neuroticism can be demonstrated in the relationship between two job demands (i.e., work pressure and working overtime) and both burnout and work engagement in 257 Dutch judges. It is important to better understand the interaction effects between various job demands (work pressure and working overtime) and personality on both burnout and work engagement in judges given their increased risk of burnout and lower work engagement due to cognitively and their emotionally demanding work. Three hypotheses were tested in a cross-sectional design study. Moderation analyses showed that, as expected, conscientiousness significantly boosted the relationship between working overtime and work engagement. Hence, high scorers on conscientiousness showed more work engagement when working overtime. Also, extraversion moderated the relation between working overtime and work engagement, but only at a low level of extraversion. Thus, contrary to expectations, introverts showed more work engagement when they work overtime. Also, significant main effects were found. Work pressure and neuroticism related positively to burnout, while extraversion and agreeableness related negatively to burnout. Moreover, extraversion, agreeableness and conscientiousness related positively to work engagement. In our study, conscientiousness, extraversion and agreeableness can be considered as personal resources for judges, in line with the Conservation of Resources (COR) theory. Especially conscientiousness can facilitate judges to cope with challenging working circumstances and introversion ensures that judges stay engaged despite working overtime.

Personality Traits and Motives in Table Tennis Players.

This study aims to investigate table tennis players' personality traits and motives in the frame of the Big Five personality model and the self-determination theory (SDT) of motivation. A total of 447 Italian table tennis players ranging in level of play between the regional and international levels participated in the study. They completed a self-report questionnaire measuring their personality traits and motives to play table tennis. Findings showed conscientiousness as the most distinctive trait of table tennis players. No differences were detected between elite and non-elite players. Table tennis players are mainly motivated by factors belonging to the intrinsic pole of the self-determination motivational continuum. External reinforcements represent a minimal incentive to play this sport both for elite and non-elite athletes. The current findings help clarify the relationships between personality traits, playing certain types of sports, and achieving different performance levels. We conclude by outlining implications for applied sport psychology.

Comparative analysis of big five personality traits in obese and normal weight type 2 diabetes mellitus patients.

Background and Objectives: Type 2 diabetes has multifactorial causation, with obesity and metabolic dysregulation being two of them. Personality traits are also known to influence many metabolic processes and have been associated with the pathogenesis of diabetes as well as obesity. The objective of the study was to analyze the differences in the big five personality traits of normal-weight type 2 diabetes mellitus, obese type 2 diabetes mellitus patients, and healthy controls. Methods: A total of 70 subjects were included in the study after outpatient-based screening, of which 40 were type 2 diabetes patients (20 obese and 20 normal weight) and 30 were healthy controls. After the anthropometric screening, the personality assessment of the subjects was done using the Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness-Five Factor Inventory (NEO-FFI). The differences in the scores of each trait for every group were analyzed by analysis of variance (ANOVA) with Tukey's honest significant difference (HSD) post hoc corrections. The difference in the scores between controls and diabetes patients was also compared by independent samples t-test. Results: The neuroticism score was significantly higher in both the normal-weight diabetes group (P = 0.01) and obese diabetes group (P = 0.02) as compared to the control group. All diabetes patients when compared with healthy controls had a significantly higher neuroticism score (P = 0.00) while their score of openness was significantly lower (P = 0.035) than healthy controls. Interpretation and Conclusion: This study identifies the association of personality with type 2 diabetes mellitus. The diabetes patients have higher neuroticism and lesser openness to experience as traits of personality. Importantly, this association is present irrespective of the obesity status of the patients.

A meta-analytic review of Internet gaming disorder and the Big Five personality factors.

Two systematic reviews have been conducted to summarize the literature on Internet Gaming Disorder (IGD) and personality. However, the data was not synthesized statistically, imposing a limit to their conclusions. The current study aimed to extend on the two reviews by conducting a series of five meta-analyses, one for each of the Big Five personality factors, to examine their relationships with IGD. A comprehensive search was conducted on the databases PsycArticles, PsycInfo, and Web of Science from inception to 29 July 2021. The data was analyzed using Meta-Essentials and the random effects model was used to obtain the pooled estimate of the effect size. A total of 12 articles were included (n = 145 to 3389). IGD was not significantly correlated with openness to experience (r = -0.05). However, IGD was negatively correlated with conscientiousness (r = -0.29), extraversion (r = -0.15), and agreeableness (r = -0.17), and positively correlated with neuroticism (r = 0.20). Age moderated the relationships between IGD and openness to experience and conscientiousness. The results were broadly consistent with the DSM-5 IGD criteria and the Big Five personality framework. Future research directions might include examining age as moderator variables, and using appropriate instruments based on the DSM-5 IGD criteria.

Dream Recall Frequency, Lucid Dream Frequency, and Personality During the Covid-19 Pandemic.

Dream recall frequency and lucid dream frequency showed large inter-individual differences that are partly related to personality dimensions. However, as dream research is a small field, independent studies are necessary to build a solid empirical foundation. The present online survey included 1,537 participants (1150 women, 387 men) with a mean age of 35.1 ± 15.8 years. Whereas the relationship between openness to experience and dream recall frequency was in line with previous research - supporting the life-style hypothesis of dream recall, the associations between the Big Five personality factors and lucid dream frequency are less homogenous; for example, the negative relationship between neuroticism and lucid dream frequency. Even though the effect sizes of these associations are small, the findings can help in identifying links between waking and dreaming. Moreover, it was found that lucid dream frequency was related to Covid-19-related worries, whereas dream recall frequency was not.

The Road to Becoming a Psychologist: Indicators of Success and Hardship during the University Years.

In order to become a full-fledged psychologist, one must undertake a long, demanding, and quite difficult journey in academia. The academic journey holds a promise of delivering knowledge, interesting theories, and strategies on helping those who need psychological assessment and/or treatment. However, the constant expectation of keeping up with the material, of succeeding in tests and exams, and of preparing to proceed to the next educational level can be daunting and exhausting. In line with the topic of this special issue, this paper addresses factors contributing to academic success at the undergraduate, graduate, and post-graduate levels of psychology. Utilizing the available literature on the Big Five personality classification scheme, high conscientiousness was found to be the most consistent predictor of success, although curiously, this relationship was only found to be reliable at the undergraduate level. Less robust findings included high agreeableness and low neuroticism as predictors of general academic success in all tertiary levels of education. The importance of mentorship figures in psychology, and a highlight of its lack of widespread implementation at the undergraduate level, are also addressed. Additionally, we discuss the negative implications of the impostor phenomenon and of loneliness, which students at all levels may experience as common barriers to scholastic success in psychology. Following a discussion of each factor as outlined above, there is a brief literature review regarding ways that its constraining effects may be limited or its positive effects possibly enhanced.

What personality types dominate among nurses and paramedics: A scoping review?

BACKGROUND: Certain personality traits captured by the Big Five framework have been shown to play an important role in predicting burnout in response to stressors, with evidence they reflect a relationship to psychological resilience. Understanding such distributions can subsequently serve to facilitate identification and implementation of more specifically targeted preventative strategies. METHODS: Arksey and O'Malley's five stage scoping was used to review the literature. The research question that guided this scoping was: Big Five personality factor predominance's among nurses and paramedics, and any relationships with constructs critical for wellbeing. Five electronic databases were searched during November 2018: PsycINFO, Embase, Medline, ProQuest and Scopus. RESULTS: Eighteen articles met inclusion criteria. Two broad themes emerged: those specifically about personality traits of nurses and/or paramedics, and those concerned with various associations between one or other construct and personality trait(s). Low Neuroticism and higher Extraversion are considered desirable traits in nurses and paramedics as they have each been found to have a negative correlation with burnout. CONCLUSIONS: Nurses and paramedics with higher Neuroticism and lower Extraversion suggest being less suited to their profession, particularly when exposed to critical incidents.

Characteristics of Veterinary Students: Perfectionism, Personality Factors, and Resilience.

Perfectionism is a topic relevant to veterinary medicine and has previously been found to be related to higher levels of stress and poorer mental health outcomes. However, many aspects of perfectionism have yet to be researched among veterinary students. This research investigates the relationship between perfectionism and the "Big Five" personality factors. Additionally, the relationship between resilience and neuroticism is addressed. This research includes a sample of 99 veterinary students enrolled at a College of Veterinary Medicine in the southeastern United States. Students completed the Multidimensional Perfectionism Inventory (MPI), the Big Five Inventory (BFI), and the Brief Resilience Scale (BRS). Results show that perfectionism is significantly correlated with personality factors; specifically, self-oriented perfectionism and socially prescribed perfectionism are associated with neuroticism, socially prescribed perfectionism is associated with agreeableness, and self-oriented perfectionism is associated with conscientiousness. Neuroticism was found to have a significant negative correlation with resilience. Findings indicate that veterinary mental health professionals and educators should consider implementing specific strategies to help students develop a healthy balance in their perfectionistic beliefs and have targeted interventions to promote student resilience.

Elaboración de la versión breve del Cuestionario de Personalidad IPIP-Revisado: Control del sesgo de aquiescencia / Elaboração da versão breve do Inventário de Personalidade IPIPRevisado: controle do viés de aquiescência / Development of a Brief Version of the Personality Inventory IPIPRevised: Control of the Acquiescence Response Bias

Resumen En los últimos años se han desarrollado medidas breves de los cinco factores de personalidad, sin embargo, la ganancia práctica de tiempo provista por las formas breves puede implicar propiedades psicométricas más débiles de los instrumentos. En la construcción de escalas breves, para mantener propiedades psicométricas adecuadas se debe emplear criterios teóricos y empíricos en la selección de los ítems y minimizar los sesgos de respuesta, como el de la aquiescencia (AC), que hace referencia a la tendencia de las personas a estar de acuerdo con afirmaciones positivas independientemente del contenido de la afirmación. Teniendo esto en cuenta, el objetivo principal del presente estudio fue desarrollar un instrumento breve (30 ítems), de dominio público, para medir los cinco factores de personalidad en población latina, controlando el sesgo de respuesta AC. La muestra estuvo compuesta por 910 participantes, 543 de sexo femenino (59.6 %) y 367 de sexo masculino (40.3 %), con edades comprendidas entre los 15 y los 80 años (M = 29.52; DT = 12.25), pertenecientes a la ciudad de Córdoba, Argentina. Para el proceso de validación se propuso realizar un estudio de convergencia con las cinco escalas del NEO-FFI, un análisis de diferencia de grupos según el sexo y la edad de los participantes, y un estudio de validez predictiva respecto a algunas actividades recreacionales (uso de drogas, irresponsabilidad, amistad, erudición/creatividad y comunicación). Los resultados indican que el IPIP-R-30 presenta una estructura factorial de cinco factores, índices de confiabilidad adecuados tanto de consistencia interna como de estabilidad temporal, evidencia de validez convergente con las escalas del NEO-FFI, evidencia de diferencia de grupos según sexo y edad, y validez predictiva de la frecuencia de diferentes categorías de actividades específicas. De esta manera, se puede concluir que el IPIP-R-30 constituye una herramienta válida de evaluación de los rasgos de personalidad en nuestro medio, con puntuaciones libres del sesgo de AC.

Abstract In recent years, brief measures of the five personality factors have been developed; however, the practical gain of time provided by the brief versions may imply weaker psychometric properties of the instruments. To maintain adequate psychometric properties in the construction of brief scales, theoretical and empirical criteria should be used in the selection of items, and response biases such as acquiescence (AC) should be minimized. The term AC refers to people's tendency to agree with positive statements, regardless of their content. The main purpose of the present study is to develop a brief public domain instrument (30 items) to measure the five personality factors in the Latin American population, controlling the AC response bias. The sample consisted of 910 participants, 543 women (59.6 %) and 367 men (40.3 %), age range 15-80 years (M = 29.52; DT = 12.25) from the city of Córdoba, Argentina. For the validation process, a convergence study with the five NEO-FFI scales, an analysis of group differences according to the participants' sex and age, and a predictive validity study regarding recreational activities (drug use, irresponsibility, friendship, erudition/creativity, and communication) were performed. The results indicate that the IPIP-R-30 presents a five-factor factorial structure, adequate reliability indices of both internal consistency and temporal stability, evidence of convergent validity with the NEO-FFI scales, evidence of group differences as regards sex and age, and frequency predictive validity of different categories of specific activities. Thus, it can be concluded that the IPP-R-30 is a valid tool for assessing personality factors in our environment, with scores free of AC bias.

Validating the Parkinson's disease caregiver burden questionnaire (PDCB) in German caregivers of advanced Parkinson's disease patients.

BACKGROUND: Advanced Parkinson's disease (PD) may place a high burden on patients and their caregivers. Understanding the determinants of caregiver burden is of critical importance. This understanding requires the availability of adequate assessment tools. Recently, the Parkinson's disease caregiver burden questionnaire (PDCB) has been developed as a PD-specific measure of caregiver burden. However, the PDCB has only been evaluated in a sample of Australian caregivers of patients at a less advanced stage of the disease. OBJECTIVE: We tested whether a German translation of the PDCB qualifies as an adequate measure of caregiver burden in a German sample of caregivers of advanced patients with PD. METHODS: We collected PDCB data from 65 caregivers of advanced patients with PD. Reliability of the scale was assessed and compared against the original version. To validate the German version of the PDCB, we examined the correlations with the caregiver burden inventory (CBI), the short form 36 health survey (SF-36), the Parkinson's disease quality of life questionnaire 39 (PDQ-39), disease duration, and the amount of caregiving time. RESULTS: The total PDCB score proved to be reliable and to be significantly related to CBI and SF-36 scores. PDCB scores also increased with increasing amounts of caregiving time. CONCLUSIONS: The German version of the PDCB appears to be an adequate measure of caregiver burden in caregivers of advanced PD patients.

The Big Five personality factors and psychological well-being following stroke: a systematic review.

PURPOSE: To identify and appraise studies investigating the relationship between the Big Five personality factors and psychological well-being following stroke and evidence for personality change. METHODS: Systematic searches of six databases (PsychINFO, CINAHL, Ovid Medline, Cochrane, PubMed, and Web of Science) were conducted from inception to June 2017. Studies involving adult stroke samples that employed a validated measure of at least one of the Big Five personality factors were included. Two reviewers independently assessed the eligibility and methodological quality of studies. RESULTS: Eleven studies were identified that assessed associations between personality and psychological well-being after stroke (nine studies) or post-stroke personality change (two studies). A consistent finding was that higher neuroticism was significantly related to poorer psychological well-being. The evidence for the other Big Five factors was mixed. In terms of personality change, two cross-sectional studies reported high rates of elevated neuroticism (38-48%) and low extraversion (33-40%) relative to normative data. Different questionnaires and approaches to measuring personality (i.e., self vs. informant ratings, premorbid personality vs. current personality) complicated comparisons between studies. CONCLUSIONS: People high on neuroticism are at increased risk of poor psychological well-being after stroke. Prospective longitudinal studies are needed to address the limited research on post-stroke personality change. Implications for rehabilitation High neuroticism is associated with poorer psychological well-being after stroke. Assessing personality characteristics early after stroke may help to identify those at risk of poor psychological outcomes.

Validity evidence of two short scales measuring the Big Five personality factors.

The objective of this study was to obtain evidence of the convergent and factor validity of the Reduced Scale of Big Five Personality Factors (ER5FP), with 20 items, and of the Reduced Inventory of Big Five Personality Factors (IGFP-5R), with 32 items. The two Brazilian scales were administered to 554 participants aged 16-69 years (M = 30.6, SD = 8.6). The measurement model of each instrument was tested using confirmatory factor analysis. Both scales showed an adequate adjustment of the measurement model to the data (root mean square error of approximation < .06; standardized root mean square residual < .06) after excluding a number of items. Correlations between the factors of both instruments were estimated. Moderate evidence of convergent validity was found for Extraversion, Neuroticism, and Openness to Experience (raw correlations ranging from .44 and .57, and disattenuated correlations from .60 to .80). For Agreeableness and Conscientiousness, weaker evidence was found (raw correlations of .33 and .29, and disattenuated correlations of .48 and .43, respectively).

Social-Demographic Indicators, Cognitive Ability, Personality Traits, and Region as Independent Predictors of Income: Findings from the UK Household Longitudinal Study (UKHLS).

This paper reports on a longitudinal study of over 12,000 people based on the UK Household Longitudinal Study data. We were interested in their monthly income (as the criterion variable) as it related to their gender, age, education, occupation, personality, intelligence, and region where they lived (as the predictor variables). Correlations showed that, after occupation and education, gender and cognitive ability (particularly numeric ability) were the strongest correlates of income. Hierarchical regressions showed that age and gender accounted for 9% of the variance, intelligence and personality added another 5%, and education and occupation added a further 15%, while region added a further 1%. All four models were statistically significant (p < 0.001). The study suggests that, in future research of this kind on the personal correlates of income, social-demographic, psychological, and regional factors all need to be considered. Limitations are acknowledged.

For Agreeableness and Conscientiousness, weaker evidence was found (raw correlations of .33 and .29, and disattenuated correlations of .48 and .43, respectively).

The role of personality in body image dissatisfaction and disordered eating: discrepancies between men and women.

BACKGROUND: Body image and disordered eating research has focused mostly on the female experience. The present study examined gender differences in the relationship between personality, disordered eating, and body image dissatisfaction. METHODS: Participants were 238 female and 85 male undergraduates (Mage = 20.52 years, SD = 4.22) at a Canadian university. Materials included a battery of self-report questionnaires pertaining to personality, body image, and disordered eating. RESULTS: As expected, females reported more body dissatisfaction and disordered eating than males. Personality factors were found to be significantly related to the experience of body dissatisfaction in both genders. Further, several personality traits significantly contributed to the prediction of male (high Neuroticism, low Conscientiousness) and female (high Neuroticism) body dissatisfaction beyond the influence of body mass index (BMI). Interestingly, and contrary to findings with female participants, personality traits were not significantly related to disordered eating scores in men. Among women, disordered eating scores were significantly predicted by high Neuroticism and Extraversion, and low Conscientiousness. CONCLUSIONS: Although the relationship between disordered eating, body image dissatisfaction, and personality is well-documented in females, this relation may differ for males. The focus on male body image has been increasing in Western society; exploring how males view their bodies may be beneficial to researchers and clinicians alike.

Predicting Romantic Interest at Zero Acquaintance: Evidence of Sex Differences in Trait Perception but Not in Predictors of Interest.

We evaluated five competing hypotheses about what predicts romantic interest. Through a half-block quasi-experimental design, a large sample of young adults (i.e., responders; n = 335) viewed videos of opposite-sex persons (i.e., targets) talking about themselves and responders rated the targets' traits and their romantic interest in the target. We tested whether similarity, dissimilarity, or overall trait levels on mate value, physical attractiveness, life history strategy, and the Big-Five personality factors predicted romantic interest at zero acquaintance, and whether sex acted as a moderator. We tested the responders' individual perception of the targets' traits, in addition to the targets' own self-reported trait levels and a consensus rating of the targets made by the responders. We used polynomial regression with response surface analysis within multilevel modeling to test support for each of the hypotheses. Results suggest a large sex difference in trait perception; when women rated men, they agreed in their perception more often than when men rated women. However, as a predictor of romantic interest, there were no sex differences. Only the responders' perception of the targets' physical attractiveness predicted romantic interest; specifically, responders' who rated the targets' physical attractiveness as higher than themselves reported more romantic interest.
