Cross-sectional age differences in the HEXACO personality: Results from a Japanese sample

Little research has been conducted on personality development in non-Western countries. The present study investigated age differences in personality in Japanese middle adults (N = 2000; M = 40.94 years; SD = 5.35, range 30–49; 1000 women). After controlling for educational level, annual income, marital status, and gender, it was found that the level of Emotionality was negatively associated with age. Honesty–Humility, on the other hand, was positively associated with age. However, Extraversion, Agreeableness, Conscientiousness, and Openness were not associated with the participant age. These findings suggest that trends in personality development may differ slightly between Western and non-Western countries.     

Personality and physical activity: A systematic review and meta-analysis

Whether personality determines physical activity or its outcomes is relevant for theory and public health but has been understudied. We estimated the population correlations between Big-Five personality factors and physical activity and examined whether they varied according to sample characteristics and study features. Database searches were conducted according to PRISMA guidelines, for articles published in the English language prior to November 1st, 2013. Sixty-four studies including a total of 88,400 participants yielded effects (k) for Extraversion (88), Neuroticism (82), Conscientiousness (69), Openness (51) and Agreeableness (52). Significant mean r was found for Extraversion (r = .1076), Neuroticism (r = −.0710), Conscientiousness (r = .1037) and Openness (r = .0344), but not Agreeableness (r = .0020). Effects were moderately heterogeneous (I² range = 44–65%) and varied by sample characteristics (e.g., age, gender, or clinical status) and/or study features (e.g., measure quality or item format). This analysis expands results of previous reviews and provides new support for a relationship between physical activity and Openness. Future studies should use better measures of physical activity and prospective designs, adjust for statistical artifacts, and consider advances in the conceptualization of personality.     

A genetic variant (COMT) coding dopaminergic activity predicts personality traits in healthy elderly

Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range for detecting a relationship. The present study examined associations of COMT rs4680 and personality in older adults.Genetic association analyses were carried out between the NEO and the targeted COMT rs4680 in a large, well-characterized sample of healthy, cognitively normal older adults (N = 616, mean age = 69.26 years).Three significant associations were found: participants with GG genotype showed lower mean scores on Neuroticism (p = 0.039) and higher scores on Agreeableness (p = 0.020) and Conscientiousness (p = 0.006) than participants with AA or AG genotypes.These results suggest that older adults with higher COMT enzymatic activity (GG), therefore lower dopamine level, have lower Neuroticism scores, and higher Agreeableness and Conscientiousness scores. This is consistent with a recent model of phasic and tonic dopamine release suggesting that even though GG genotype is associated with lower tonic dopamine release, the phasic release of dopamine might be optimal for a more adaptive personality profile.     

Cognitive abilities and personality traits in old age across four years: More stability than change

The current study (N = 236) examined stability and change of six cognitive abilities and three personality traits in old age (M = 74.12 years, SD = 4.40) over four years. Furthermore, we investigated whether levels of one domain were related to the other domain (and vice versa) four years later. The results showed a mean–level decline for processing speed and a mean–level increase for neuroticism. Cross–lagged effects indicated that reasoning was related to openness and conscientiousness was related to verbal knowledge four years later. In general, few and weak associations between the two domains were found. The findings showed that the development of cognitive abilities and personality traits in old age is marked more by stability than by change.     

The Mini-IPIP6: Tiny yet highly stable markers of Big Six personality

We assessed the stability of a short-form six-factor personality measure over a one-year period in a large national probability sample (N = 4289). Personality was assessed using the Mini-IPIP6—a short-form measure assessing Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience, and Honesty-Humility. Standardized estimates calculated using Bayesian Structural Equation Modelling (BSEM) indicated that all six personality dimensions were extremely stable. An alternative model using Maximum Likelihood estimation, in which residual item variances were associated over repeated assessments, yielded similar findings. These results highlight the stability of personality in the general population, even when assessed using short-form scales. The use of Bayesian models to examine the stability of personality and their application for study of change in specific developmental periods is discussed.     

The role of executive function,personality and attitudes to risks in explaining self-reported driving behaviour in adolescent and adult male drivers

Young drivers show high levels of risky driving and are over-represented in motor vehicle crash statistics world-wide. As well as personality and attitudinal factors, high rates of risk taking during adolescence may be due to poorly developed executive functions, a result of the slow maturation of the pre-frontal cortex of the brain. This study was undertaken to investigate the roles of executive function, personality, attitudes to risk in relation to self-reported driving behaviour. Adolescent (n = 46, age 16–18 years) and adult (n = 32, 25 years and over) male drivers completed a battery of neuropsychological tests to assess general cognitive ability and executive function, and questionnaires to assess driving history, personality, attitudes to physical and psychological risk as well as questionnaires of self-reported driving behaviour (Driver risk taking and Driver Attitude Questionnaire, DAQ). The adolescent drivers showed poorer executive function, higher levels of impulsivity and risk-taking, lower levels of agreeableness and conscientiousness compared to adult drivers. Regression analyses revealed that attitudes to risk, agreeableness and working memory made unique significant contributions in explaining self-reported driving behaviour. Interestingly though, better working memory was associated with higher levels of self-reported risky driving and more accepting attitudes to risky driving. Together the findings suggest that some aspects of executive function, personality, and attitudes to risk may help to explain self-reported driving behaviour. Whether these findings are relevant to female drivers and apply to on-road driving behaviour should be the focus of future studies.     

Adversity in adolescence predicts personality trait change from childhood to adulthood

This study examined whether cumulative adversity in adolescence predicted changes in the Big Five traits from childhood to adulthood in the Project Competence Longitudinal Study sample (N = 205) followed from childhood (age 10) through adolescence into adulthood (age 30). Personality traits were measured in childhood through multiple methods and in adulthood by self-report. Cumulative adversity, assessed in adolescence, differentiated independent adversity (likely unrelated to participants’ behavior) from dependent adversity (resulting from participants’ own behavior). Participants’ personality traits were modestly stable over 20 years, although Openness showed greater stability. Independent and dependent adversity predicted increases in Negative Emotionality/Neuroticism, and dependent adversity predicted decreases in Constraint/Conscientiousness and Agreeableness from childhood to adulthood, suggesting that cumulative adversity shapes personality development in young people.     

Development and initial assessment of a short measure for adult playfulness: The SMAP

This study reports an initial evaluation of a new short measure for adult playfulness (SMAP). In data from a construction (N = 266), and two replication samples (N = 147 students, N = 215 adults), a one-dimensional solution showed the best fit for the data and satisfactory internal consistency (.80–.89) was found (test–retest correlation = .74; 12–16 weeks). Younger adults scored higher in playfulness than older ones. The SMAP demonstrated robust correlations with measures for adult playfulness and the need for play. Cheerfulness and culture along with low seriousness and low conscientiousness were its best predictors. In ratings of an unordered work-space and a surrealistic painting, playful adults expressed higher liking for and lower disapproval of these compared to non-playful adults. Overall, the new scale yielded good psychometric properties and first evidence on its validity was encouraging. The SMAP has been developed for an economic, global assessment of adult playfulness, which is still an understudied topic in personality research.     

Agreeableness and brain activity during emotion attribution decisions

Within the Big 5 model of personality, Agreeableness is a trait-dimension associated with the tendency to behave prosocially; highly agreeable people tend to be highly cooperative and altruistic. This study was designed to test for associations between Agreeableness and the way people decide the cause of another person’s emotional reaction (emotion attribution). Behavioral and neuroimaging (fMRI) data were collected while participants (n = 72) performed an emotional attribution task. During the emotion attribution task, participants decided which of two social–emotional scenes they believed caused another person’s emotional reaction. Converging evidence indicated that highly agreeable people tend to make emotional attribution decisions more quickly and exhibit greater temporoparietal junction activity during emotion attribution decisions, compared to low agreeable people.     

Age trends in HEXACO-PI-R self-reports

We examined age differences in the six broad HEXACO personality factors and their defining facets, using self-reports from an online sample (N ≈ 100,000, ages 14–74). Honesty-Humility showed an upward trend of about one full standard deviation unit between ages 18 and 60. Age trends for Emotionality and Extraversion differed by facet, but overall were downward for Emotionality and upward for Extraversion. Agreeableness showed relatively weak age trends. Conscientiousness and Openness showed upward age trends during the teen years (extending to the mid-20s for Conscientiousness), but age trends thereafter differed considerably by facet. Results are discussed in relation to previous findings for the Big Five, to the “age-crime curve”, and to possible evolved developmental origins.     

Childhood antecedents of Agreeableness: A longitudinal study from preschool to late adolescence

Although the consensus view is that Agreeableness originates from childhood difficultness and regulatory deficits, few studies have investigated such assumptions longitudinally. In this study, we examined this issue by assessing enduring and mediating effects of self-regulation as well as the impact of parenting behaviors on the development of Agreeableness from preschool to late adolescence. Longitudinal data from 965 Norwegian families following children from 1.5 years to 16.5 years were used. Path analyses revealed childhood difficultness at age 4 to be related to Agreeableness at age 16.5; this effect was mediated through emotion regulation in late childhood. However, such mediation effects were primarily found when parents used punitive practices towards their children. Our findings point to personality coherence throughout development.     

Do you see my growth? Two longitudinal studies on personality development from childhood to young adulthood from multiple perspectives

Personality developmental studies typically rely on single reporter data, while multi-informant studies are rare. In two longitudinal studies, the present investigation examined inter-judge differences in the development of the Big Five personality traits from childhood to young adulthood. Study 1 investigated personality development as judged by the self and parents from age 12 to 17 to 29 (N = 186). Study 2 investigated personality development annually from age 12 to 18 as judged by the self, and both parents and siblings (N = 574). Results showed personality maturation from childhood to young adulthood with disruptions during adolescence. Only parent-reports indicated maturation in adolescents’ negative affectivity (decreases in N), while self-reports indicated maturation in self-regulatory traits (increases in A and C).     

Do personality traits affect responsiveness of juvenile delinquents to treatment?

ObjectiveThe aim of the present study was to examine the moderating role of Big Five personality traits in short and long term effectiveness of MultiSystemic Therapy (MST) for serious and persistent juvenile delinquents.MethodData of a randomized controlled trial (N = 256) were used to examine the research question.ResultsExtraversion, Emotional Stability and Openness did not moderate short term effectiveness of MST, but Conscientiousness and Agreeableness did: MST was most effective for highly conscientious and highly agreeable juvenile delinquents. Personality did not moderate the effectiveness of MST on aggression or the long-term effectiveness of MST.ConclusionThis study shows the importance of personality traits for short-term treatment outcomes, effectiveness of MST differs for high/low Agreeableness and Conscientiousness.     

Personality traits and affective states: Relationships with and without affect induction

Substantial evidence shows that extraversion is related to positive affect (PA) and neuroticism is related to negative affect (NA), and there are several possible explanations for these relationships. The current paper replicates these findings and examines relationships between the other Big Five traits with general positive and negative states (N = 257). Agreeableness was negatively related to NA, while conscientiousness and openness were positively related to PA. Next, affect was induced and extraversion and conscientiousness predicted changes in affect following an affect-induction (N = 262). The current findings support some theoretical understandings of broad personality traits and their relationships to general affect, and also suggests some refinements.     

Personality change in adolescence: Results from a Japanese sample

We examined developmental trends in personality traits during adolescence by using data from the secondary school affiliated with the University of Tokyo (N = 3656; range 12–18; 1832 female), collected from 1981 to 2010. Hierarchical linear modeling analyses revealed cumulative mean-level changes in personality averaging approximately 1 SD across adolescence. Scales related to Neuroticism showed linear increases, and those related to Extraversion showed distinct developmental patterns: General Activity and Rhathymia did not change, while Ascendance and Social Extroversion declined. Additionally, we found significant gender and birth cohort effects on personality. Although the intercepts differed according to both factors, the trajectories were different only for the birth cohort. These findings suggest that personality development trajectories differ according to the sociocultural context.     

Personality traits as predictors of trauma-related coping self-efficacy: A three-wave prospective study

Aim of the present three-wave study was to examine to what extent personality traits and general self-efficacy measured before exposure to a potentially traumatic event (PTE) prospectively predict coping self-efficacy (CSE) perceptions, and to test whether outcomes are biased by the timing of assessment of personality traits. The study was conducted within a large probability-based multi-wave representative internet panel in the Netherlands (N^total = 1154).ResultsFindings for both personality assessments (2009, 2011) were similar. Among respondents with low levels of PTSD-symptomatology, higher levels of emotional stability and agreeableness were associated with higher levels of CSE, while among those with relatively high levels of PTSD-symptomatology emotional stability alone was independently predictive of CSE. After adding personality traits to the model, general self-efficacy, demographic and event-related variables were not predictive of CSE, with the exception of time since the event for the high-symptoms group.ConclusionsEmotional stability most strongly and systematically predicts CSE following PTE’s, regardless of the moment it was assessed. Agreeableness is only predictive of CSE among those with low levels of PTSD-symptomatology. Timing of assessment of personality did not influence results. In sum the personality traits emotional stability and agreeableness provide (limited) information on CSE levels among adults following PTE’s.     

Validation de la version francophone de l’Emotion Regulation Checklist (ERC-vf)

Introduction and objectiveThis article presents two validation studies of the French version of the Emotion Regulation Checklist (Shields & Cicchetti, 1998; ERC-vf, Nader-Grosbois, 2013) led with preschoolers. This questionnaire is applicable to 3–12 years old children with and without disorder.MethodIn the study 1 (n = 152), the teachers filled the ERC-vf and a personality scale. In the study 2 (n = 71), the ERC-vf was completed two times by the teachers and by the parents who also filled other measures of emotion regulation and of social competences.ResultsThe study 1 shows a good internal consistency and a two-factor structure (emotion regulation and dysregulation). The scores for these factors are significantly linked with developmental ages, the global level of intellectual efficiency and specific factors of personality. The study 2 shows a good inter-judges agreement, a stability test-retest and the external convergent validity between scores in ERC-vf and in other measures of emotion regulation and of social competences.ConclusionAs the ERC-vf has good psychometric properties, it may be used for research and for assessment in intervention in French-speaking areas.     

Personality measured as Murray’s psychological needs and all-cause mortality: 41 years of follow-up of a population-based sample

ObjectiveTo examine the associations between personality traits, measured as Murray’s psychological needs, and mortality over 41 years.MethodWe used a general population sample aged 18–65 (n = 1094) examined in 1970 according to the Cesarec-Marke Personality Schedule (eleven traits) linked to mortality data. Internal associations were examined using factor analysis, and their associations with mortality using Cox proportional hazard regression models.ResultsDuring follow-up, 513 persons died. In men aged 26–45, achievement and affiliation predicted increased mortality: HR = 1.19, 95% CI 1.04–1.36 and HR = 1.16, 95% CI 1.01–1.33 per step on a stanine scale. In men aged 18–25, nurturance was protective: HR = 0.77, 95% CI, 0.64–0.98 per stanine. In women aged 18–25, feelings of guilt increased the risk of mortality, while dominance was protective: HR = 1.38, 95% CI 1.09–1.75, and HR = 0.74, 95% CI 0.55–0.99 per stanine, respectively. In women aged 46–65, exhibition increased the risk of mortality: HR = 1.09, 95% CI, 1.00–1.18 per stanine. There were no significant associations when all age groups were combined.ConclusionsPersonality traits, measured as Murray’s needs, associated with mortality, but the differed according to age at assessment and sex.     

Is empathizing in the E–S theory similar to agreeableness? The relationship between the EQ and SQ and major personality domains

This study investigated the relationship between the Empathy Quotient (EQ) and Systemizing Quotient (SQ) and major personality domains (Neuroticism, Extraversion, Openness to Experience, Agreeableness, Conscientiousness, and Honesty–Humility) using two personality questionnaires: the NEO-FFI and the HEXACO-PI. Participants who responded were 1382 university students for the NEO-FFI, and 842 for the HEXACO-PI, with the EQ and SQ. The results showed almost no relationship between the EQ and SQ and the five-factor personality domains of the NEO-FFI. The regression analysis showed that the NEO-FFI explained only 2–3% of the variance of the EQ/SQ, while in the domains of the HEXACO-PI extraversion moderately correlated with the EQ (r = 0.32) and openness showed the highest correlation with the SQ (r = 0.44). The regression analysis showed that the HEXACO-PI explained 22% of the variance of the EQ and 28% of the variance of the SQ. The strong relationship between the EQ and agreeableness, which was reported as r = 0.75 by Nettle (2007), was hardly found in the results of the NEO-FFI (r = 0.16) and HEXACO-PI (r = 0.17). These results suggest that that empathizing and systemizing, as one-dimensional constructs, are not substantially related to personality, although some weak relationship might be observed between the EQ/SQ and some personality domains.     

Personality traits and body mass index in Asian populations

Research on personality and adiposity has focused primarily on Western samples; less is known about the personality correlates of BMI in Asian populations. We examined the association between personality and body mass index (BMI) among community-dwelling Japanese adults (N = 380), Chinese adolescents (N = 5882), and a meta-analysis inclusive of a published Korean sample (total N = 10,304). In the new samples and meta-analysis, Extraversion and Agreeableness were associated with higher BMI among men. In contrast to what is often found in Western samples, Conscientiousness was mostly unrelated to adiposity. These findings link pro-social tendencies to overweight among Asian men; Conscientiousness may be less relevant for BMI in Eastern societies with a low prevalence of obesity and strong social norms for eating but not thinness.
