RESUMO
OBJECTIVES: The assessment of personality traits is most often based on self-report. However, a growing body of research has shown that informant-report is a valuable and too often overlooked source of unique information. The aim of this study was to validate the French version of the informant-report form of the Big Five Inventory-2 (BFI-2) which assesses 15 facet traits in addition to the five major trait domains. METHODS: We asked 699 psychology and sports science and technology students to describe a person they knew well using the BFI-2 and obtained 661 valid records with demographic information. The data were analyzed using a bi-factor exploratory structural equation model with five bifactors corresponding to the Big Five domains, and three group factors (facets) each. RESULTS: This model had an excellent overall fit. Cronbach's alpha coefficients for the five domains were very satisfactory and the McDonald's omega coefficients were even better. The scales that measured the five major factors were therefore highly reliable, although Extraversion was somewhat less so. The scales measuring facets all had high reliability as measures of the whole formed by the major factor and the group factor. In addition, ten of them were reliable measures of their specific factor, and the remaining five appeared to be pure measures of the five domains. CONCLUSIONS: The informant-report form of the BFI-2 is a reliable instrument which is easy and quick to administer. These qualities should enable clinicians and researchers to exploit the much-neglected source of original information provided by informant-reports.
RESUMO
OBJECTIVE: Subjective age has been implicated in a range of health outcomes but its associations with Fear of Falling (FoF) are unknown. The present study examined the relation between subjective age and FoF in large national sample. METHODS: Participants were drawn from the National Health and Aging Trends Study (NHATS, 2011-2017). 1,679 participants provided data on FoF, subjective age, demographic factors, depressive symptoms, prior falls, self-rated health and measures of the Short Physical Performance Battery. FoF was assessed again 7 years later. RESULTS: Regression analyses revealed that an older subjective age was related to a 24% higher likelihood to develop FoF 7 years later. This association was independent of age, sex, educational attainment, race and prior falls. In addition, depressive symptoms, self-rated health, and physical inactivity mediated the associations between subjective age and FoF. CONCLUSIONS: The present study showed that an older subjective age is related to the development of FoF over time, and further identified psychological and functional pathways that may explain this association. These results confirm the role of subjective age on one of the markers of frailty in the aging population.

OBJECTIVE: The present study examined the association between personality traits and concurrent and incident headaches. METHODS: Participants (n = 34,989), aged 16 to 107 years were from the Midlife in the United States study, the Midlife in Japan study, the Health and Retirement Study, the Wisconsin Longitudinal Study Graduate and Siblings samples, and the Longitudinal Internet Studies for the Social Sciences. Demographic factors, personality traits, and headaches were assessed at baseline. Headaches were assessed again 4 to almost 20 years later. RESULTS: Across the samples, higher neuroticism was related to a higher likelihood of concurrent (combined odd ratio = 1.41, 95% confidence interval [CI] = 1.28-1.55, p < .001) and incident (combined odd ratio = 1.28, 95% CI = 1.12-1.46, p < .001) headaches, whereas higher extraversion was associated with a lower likelihood of concurrent (combined odd ratio = 0.87, 95% CI = 0.84-0.89, p < .001) and incident (combined odd ratio = 0.90, 95% CI = 0.85-0.96, p = .001) headaches. Higher conscientiousness (combined odd ratio = 0.90, 95% CI = 0.86-0.94, p < .001) and openness (combined odd ratio = 0.95, 95% CI = 0.90-0.99, p = .025) were associated with a lower probability of reporting concurrent headaches. Agreeableness was unrelated to headaches. Sex was not a consistent moderator. CONCLUSIONS: The present study provides robust evidence that neuroticism and introversion are risk factors for headaches in concurrent and prospective analyses across multiple cohorts.

BACKGROUND: Patients with a metastatic breast cancer suffer from a deteriorated health-related quality of life and numerous symptoms such as pain, severe fatigue and a decrease of their physical fitness. As the feasibility of a physical activity program has been demonstrated in this population, ABLE02 aims to assess the efficacy of a 6 month-physical activity program using connected devices to improve health-related quality of life and to reduce fatigue in women with metastatic breast cancer. METHODS: ABLE02 is a prospective, national, multicenter, randomized, controlled and open-label study. A total of 244 patients with a metastatic breast cancer, with at least one positive hormone receptor and a first-line chemotherapy planned, will be randomly assigned (1:1 ratio) to: (i) the intervention arm to receive physical activity recommendations, an activity tracker to wear 24 h a day during the whole intervention (6 months) with at least three weekly walking sessions and quizzes each week on physical activity and nutrition (ii) the control arm to receive physical activity recommendations only. Health-related quality of life will be assessed every 6 weeks and main assessments will be conducted at baseline, M3, M6, M12 and M18 to evaluate the clinical, physical, biological and psychological parameters and survival of participants. All questionnaires will be completed on a dedicated application. DISCUSSION: An activity program based on a smartphone application linked to an activity tracker may help to improve quality of life and reduce fatigue of patients with a metastatic breast cancer. The growth of e-health offers the opportunity to get real-time data as well as improving patient empowerment in order to change long-term behaviors. TRIAL REGISTRATION: NCT number: NCT04354233 .

OBJECTIVES: 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. METHODS: Participants (Nâ >â 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. RESULTS: The meta-analyses identified an association between higher neuroticism and an increased risk of concurrent (odds ratioâ =â 1.20, 95% confidence interval [CI]â =â 1.16-1.24; pâ <â .001, I2â =â 40.27) and incident (hazard ratioâ =â 1.11, 95% CIâ =â 1.08-1.14; pâ <â .001, I2â =â 0) arthritis and between higher conscientiousness and a decreased risk of concurrent (odds ratioâ =â 0.88, 95% CIâ =â 0.86-0.90; pâ <â .001, I2â =â 0) and incident (hazard ratioâ =â 0.95, 95% CIâ =â 0.92-0.98; pâ =â .002, I2â =â 41.27) arthritis. Higher extraversion was linked to lower risk of concurrent (odds ratioâ =â 0.92, 95% CIâ =â 0.88-0.96; pâ <â .001, I2â =â 76.09) and incident (hazard ratioâ =â 0.97, 95% CIâ =â 0.95-0.99; pâ =â .018, I2â =â 0) arthritis, and openness was related to lower risk of concurrent arthritis (odds ratioâ =â 0.96, 95% CIâ =â 0.93-0.99; pâ =â .006, I2â =â 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. DISCUSSION: Findings from 6 samples point to low neuroticism and higher conscientiousness as factors that reduce the risk of arthritis.

Background and Aim: Purpose in life is an aspect of well-being that is associated with better health outcomes in older adulthood. We examine the association between purpose in life and likelihood of a recent fall and risk of an incident fall over time. Methods: Purpose in life and falls were reported concurrently and falls were reported again up to 16 years later in four established longitudinal studies of older adults (total N = 25,418). Results: A random-effects meta-analysis of the four samples indicated that purpose was associated with a 14% lower likelihood of having fallen recently at baseline (meta-analytic OR = 0.88, 95% CI [0.84-0.92]). Among participants who reported no falls at baseline (N = 15,632), purpose was associated with a nearly 10% lower risk of an incident fall over the up to 16-year follow-up (meta-analytic HR = 0.92, 95% CI [0.90-0.94]). These associations were independent of age, sex, race, ethnicity, and education, were not moderated by these factors, and persisted controlling for physical activity and disease burden. Conclusion and Recommendations: Purpose in life is a meaningful aspect of well-being that may be useful to identify individuals at risk for falling, particularly among individuals without traditional risk factors, and be a target of intervention to reduce fall risk.
RESUMO
While the reliability of SCL-90-R subscales is often questioned, five relatively recent European studies have examined the factor structure of SCL-90-R using a bifactor model and concluded that most of these subscales are reliable. However, examination of their results shows that three subscales, Somatization, Hostility, and Phobic Anxiety, consistently had significantly higher reliability than the other six across clinical and community samples recruited in three very different European countries, Greece, Hungary, and the Netherlands. The objective of this study was to examine whether this "top-3â³ would be found in a sample from a fourth European country, France. To do this, we had 696 university students (387 women, 56 %) complete the SCL-90-R and we examined the reliability of the scales of this questionnaire by testing a bifactor model using Exploratory Structural Equation Modeling (ESEM). Our results confirmed that, in our sample, the three scales presented a higher reliability than the other six scales. It therefore seems that there exists, at least in the European cultural area, a stable structure of the SCL-90-R comprising a global distress factor and three reliable and robust specific factors: Somatization, Hostility, and Phobic Anxiety.

PURPOSE: Personality traits are associated with psychophysiological stress, but few studies focus on medical students. This study aimed to better understand the association of personality traits with the efficacy of stress management interventions for medical students. METHOD: A randomized controlled trial was conducted with fourth-year students who took the objective structured clinical examination at Bernard University Lyon 1 in December 2021. Students were randomized in cardiac biofeedback, mindfulness, and control groups. Each intervention was implemented for 6 minutes before the examination. Physiological stress levels were collected during the intervention. Psychological stress levels were rated by students at baseline and after the intervention. Personality traits were assessed via the Big-Five Inventory. Interactions between personality traits and the efficacy of the interventions were analyzed using multivariable linear regression models. RESULTS: Four hundred eighty-one students participated. Higher baseline psychological stress levels were associated with higher neuroticism and agreeableness ( ß = 10.27 [95% confidence interval {CI}, 7.40-13.13; P < .001] and ß = 3.42 [95% CI, 0.98-5.85; P = .006], respectively) and lower openness ( ß = -4.95; 95% CI, -7.40 to -2.49; P < .001). As compared with the control intervention, both stress management interventions led to lower levels of psychological ( P < .001 for both) and physiological stress levels (biofeedback: P < .001 and mindfulness: P = .009). Biofeedback efficacy varied by extraversion score for psychological ( ß = -5.66; 95% CI, -10.83 to -0.50; P = .03) and physiological stress reduction ( ß = -0.002; 95% CI, -0.003 to -0.00004; P = .045). Mindfulness efficacy varied by agreeableness score for psychological stress reduction ( ß = -7.87; 95% CI, -13.05 to -2.68; P = .003). CONCLUSIONS: Students with a high score in extraversion may benefit more from biofeedback interventions, while students with high scores in agreeableness may benefit more from mindfulness interventions.

OBJECTIVE: A small body of research has highlighted the role of the five-factor model personality traits in subjective age. However, no study has yet focused on the mechanisms through which personality could be related to subjective age among older adults. The purpose of the present study was to examine the mediating role of age-group identification in relation between personality traits and subjective age. It was hypothesized that both extraversion and openness to experience are positively related to a younger subjective age through the mediation of their negative relationship with age-group identification. METHOD: A cross-sectional study was conducted with 501 older individuals aged from 60 to 95 years who completed measures of sociodemographic variables, self-rated health, personality, subjective age, and age-group identification. RESULTS: Multiple regression analysis revealed that openness to experience was positively related to subjective age through the complete mediation of age-group identification, whereas no support was found for the relationship between extraversion and subjective age. CONCLUSION: This study fills a gap in the existing literature and reveals that openness to experience is related to a youthful subjective age, because older open individuals tend to distance themselves from their age group. Therefore, this study confirms that personality deserves attention as a predictor of subjective age, independently of sociodemographic and health-related variables.

OBJECTIVE: This study tested whether the subjective age tends to decrease after following a fall preventive program. This study also examines whether physical abilities and psychological resources at baseline are associated with this decrease in subjective age. Finally, this study tested to what extent the evolution of subjective age is concomitant with the evolution of these physical abilities and psychological resources between the beginning and the end of the program. METHOD: A sample of 42 individuals over 65 years (M = 71) took part in a program comprising 12 balance sessions. These people answered a questionnaire to assess subjective age and fear of falling, at the beginning and at the end of the program. Participants also completed Time Up and Go test, before and after the program. In addition, demographic factors, chronic diseases, subjective health, as well as depressive symptoms were assessed at baseline, and included as covariates in the analyses. RESULTS: Wilcoxon signed rank analyzes showed that participants felt younger after the intervention than before (W = 334; p < 0.05). Concretely, participants feeling younger from 6.43% at baseline to 9.63% at the end of the program. The multiple linear regression analyzes reveal that a more favorable perceived health as well as a better mobility function at baseline are associated with an increase of feeling younger at the end of the program. Finally, an improvement in functional mobility between the start and the end of the program is also associated with an increase of feeling younger. DISCUSSION: This study highlights the benefits of a fall prevention program on feeling younger for old people. In view of the benefits generated by feeling younger than one's chronological age, this study increases the interest of preventive actions to reduce the loss of functional independence in aging.

The present study examined the cross-sectional and longitudinal associations between the five major personality traits and fatigue. Participants were adults aged 16-104 years old (N > 40,000 at baseline) from the Health and Retirement Study, the National Social Life, Health, and Aging Project, the Wisconsin Longitudinal Study graduate and sibling samples, the National Health and Aging Trends Survey, the Longitudinal Internet Studies for the Social Sciences and the English Longitudinal Study of Ageing. Personality traits, fatigue, demographic factors, and other covariates were assessed at baseline, and fatigue was assessed again 5-20 years later. Across all samples, higher neuroticism was related to a higher risk of concurrent (meta-analytic OR = 1.73, 95% CI 1.62-1.86) and incident (OR = 1.38, 95% CI 1.29-1.48) fatigue. Higher extraversion, openness, agreeableness, and conscientiousness were associated with a lower likelihood of concurrent (meta-analytic OR range 0.67-0.86) and incident (meta-analytic OR range 0.80-0.92) fatigue. Self-rated health and physical inactivity partially accounted for these associations. There was little evidence that age or gender moderated these associations. This study provides consistent evidence that personality is related to fatigue. Higher neuroticism and lower extraversion, openness, agreeableness, and conscientiousness are risk factors for fatigue.

Subjective age is associated with health-related outcomes across adulthood. The present study examined the cross-sectional and longitudinal associations between personality traits and subjective age. Participants (N > 31,000) were from the Midlife in the United States Study (MIDUS), the Health and Retirement Study (HRS), the National Health and Aging Study (NHATS), the Wisconsin Longitudinal Study Graduate (WLSG) and Siblings (WLSS) samples, and the English Longitudinal Study of Aging (ELSA). Demographic factors, personality traits, and subjective age were assessed at baseline. Subjective age was assessed again in the MIDUS, the HRS, and the NHATS, 4 to almost 20 years later. Across the samples and a meta-analysis, higher neuroticism was related to an older subjective age, whereas higher extraversion, openness, agreeableness, and conscientiousness were associated with a younger subjective age. Self-rated health, physical activity, chronic conditions, and depressive symptoms partially mediated these relationships. There was little evidence that chronological age moderated these associations. Multilevel longitudinal analyses found similar associations with the intercept and weak evidence for an association with the slope in the opposite of the expected direction: Lower neuroticism and higher extraversion, agreeableness, and conscientiousness were related to feeling relatively older over time. The present study provides replicable evidence that personality is related to subjective age. It extends existing conceptualization of subjective age as a biopsychosocial marker of aging by showing that how old or young individuals feel partly reflects personality traits.

OBJECTIVE: To examine the association between Five-Factor Model personality traits and grip strength. METHOD: Adults aged 16 to 104 years old (N > 40,000) were from the Health and Retirement Study, the Midlife in the United States Study, The English Longitudinal Study of Aging, the National Health and Aging Trends Survey, the United Kingdom Household Longitudinal Study, and the Wisconsin Longitudinal Study graduate and sibling samples. Participants had data on personality traits, demographic factors, grip strength, and mediators such as depressive symptoms, physical activity, body mass index (BMI), and c-reactive protein (CRP). RESULTS: Across all samples and a meta-analysis, higher neuroticism was related to lower grip strength (meta-analytic estimate: -0.07, 95%CI: -0.075; -0.056). Higher extraversion (0.04, 95%CI: 0.022; 0.060), openness (0.05, 95%CI: 0.032; 0.062), and conscientiousness (0.05, 95%CI: 0.04; 0.065) were associated with higher grip strength across most samples and the meta-analysis. Depressive symptoms were the most consistent mediators between neuroticism and grip strength. Depressive symptoms and physical activity partly mediated the associations with extraversion, openness, and conscientiousness. Lower CRP partly mediated the association with conscientiousness. Sex moderated the associations for extraversion, openness, and conscientiousness, with stronger associations among males. Age moderated the neuroticism association, with stronger associations among younger individuals. CONCLUSION: This study provides replicable evidence that personality is related to grip strength and identifies potential moderators and mediators of these associations. Overall, higher neuroticism is a risk factor for low grip strength, whereas high extraversion, openness, and conscientiousness may be protective.

OBJECTIVES: Falls are a common and serious health problem. The present study examined the association between subjective age (i.e., feeling younger or older than one's chronological age) and falls in 2 large national samples. METHOD: Participants aged 65-105 years old were drawn from the National Health and Aging Trends Study (NHATS) and the Health and Retirement Study (HRS). Data on falls, subjective age, and demographic factors were available from 2,382 participants in HRS and 3,449 in NHATS. Falls were tracked for up to 8 (HRS) and 7 (NHATS) years. RESULTS: Cox regression analyses that included demographic covariates indicated that older subjective age increased the risk of falling in HRS (hazard ratio [HR] = 1.17, 95% confidence interval [CI] = 1.08-1.27) and in NHATS (HR = 1.06, 95% CI = 1.00-1.13). When compared to people who felt younger, people who reported an older subjective age had a higher risk of fall (HRS: HR = 1.65, 95% CI = 1.33-2.04; NHATS: HR = 1.44, 95% CI = 1.15-1.79). The associations remained significant after accounting for depressive symptoms, handgrip strength, chronic diseases, and cognitive impairment in HRS only. DISCUSSION: These results confirm the role of subjective age as an important health marker in the aging population. Subjective age assessment can help identify individuals at greater risk of falls.

OBJECTIVE: To examine the association between personality traits, defined by the Five-Factor Model, and the initiation and termination of physical activity across adulthood. DESIGN: Longitudinal analysis of participants from nine samples (N > 28,000). MAIN OUTCOME MEASURES: Physical activity status at follow-up. RESULTS: A random-effect meta-analysis revealed that higher conscientiousness, extraversion, and openness were related to a higher likelihood of initiation of physical activity over time among individuals who were physically inactive at baseline and to a lower risk of termination of physical activity among those who were physically active at baseline. In contrast, higher neuroticism was associated with a lower probability of initiation of physical activity and a higher likelihood of termination over time. Although not hypothesised, agreeableness was also associated with better physical activity outcomes over time. CONCLUSION: This study provides the largest and the longest evidence of a replicable association between personality and change in physical activity status. Personality may motivate both the initiation and termination of physical activity.
RESUMO
The present study aimed at investigating the influence of personality on both anticipatory stress vulnerability and the effectiveness of coping strategies in an occupational stressful context. Following assessment of individual personality traits (Big Five Inventory), 147 volunteers were exposed to the anticipation of a stressful event. Anxiety and cardiac reactivity were assessed as markers of vulnerability to anticipatory stress. Participants were then randomly assigned to three groups and subjected to a 5-min intervention: relaxation breathing, relaxation breathing combined with cardiac biofeedback, and control. The effectiveness of coping interventions was determined through the cardiac coherence score achieved during the intervention. Higher neuroticism was associated with higher anticipatory stress vulnerability, whereas higher conscientiousness and extraversion were related to lower anticipatory stress vulnerability. Relaxation breathing and biofeedback coping interventions contributed to improve the cardiac coherence in all participants, albeit with greater effectiveness in individuals presenting higher score of openness to experience. The present findings demonstrated that personality traits are related to both anticipatory stress vulnerability and effectiveness of coping interventions. These results bring new insights into practical guidelines for stress prevention by considering personality traits. Specific practical applications for health professionals, who are likely to manage stressful situations daily, are discussed.

OBJECTIVES: The motoric cognitive risk (MCR) syndrome, characterized by cognitive complaints and slower gait speed, is a predementia syndrome associated with dementia and mortality risk. The present study examined whether subjective age, that is, how old or young individuals feel relative to their chronological age, is related to concurrent and incident MCR syndrome. A relation between subjective age and MCR will inform knowledge on psychological factors related to dementia risk, identify who is at greater risk, and suggest a potential target of intervention. METHODS: The study sample was composed of 6,341 individuals aged 65-107 years without dementia from the Health and Retirement Study, a longitudinal study of adults aged 50 years and older. Participants completed measures of subjective age, cognitive complaints, and gait speed and provided information on demographic factors, cognition, physical activity, depressive symptoms, and body mass index (BMI) at baseline in 2008/2010. Incident MCR was assessed 4 and 8 years later. RESULTS: Controlling for demographic factors, an older subjective age was related to more than 60% higher likelihood of MCR at baseline and to around 50% higher risk of incident MCR over time. These associations remained significant when cognition, physical inactivity, depressive symptoms, and BMI were included in the analytic models. DISCUSSION: This study provides evidence that how old individuals feel is related to concurrent and incident MCR beyond the effect of chronological age, other demographic factors, physical inactivity, depressive symptoms, BMI, and cognitive functioning.

Prior research has shown that personality traits are associated with activities of daily living (ADLs) and instrumental ADLs (IADLs). To advance research on the psychological factors related to aging-related functional limitations, this study examined the relation between personality traits and both concurrent and incident functional limitations, tested whether these associations are similar across IADLs and ADLs, and tested potential mediators of these associations. Participants were drawn from eight longitudinal samples from the U.S., England, and Japan. Participants provided data on demographic variables, the five major personality traits, and on the Katz ADL-scale and Lawton IADL-scales. IADL/ADL limitations were assessed again 3-18 years later. A consistent pattern of associations was found between personality traits and functional limitations, with associations slightly stronger for IADLs than ADLs, and robust across samples that used different measures and from different cultural contexts. The meta-analysis indicated that higher neuroticism was related to a higher likelihood of concurrent and incident IADL/ADL limitations, and higher conscientiousness, extraversion, and openness were associated with lower risk. Higher agreeableness was associated with lower risk of concurrent IADL/ADL, but unrelated to incident limitations. Physical activity, disease burden, depressive symptoms, self-rated health, handgrip strength, falls, and smoking status mediated the relation between personality traits and incident IADL/ADL limitations. The present study indicates that personality traits are risk factors for both IADL and ADL limitations across multiple national cohorts, identifies potential mediators, and informs conceptual models on psychological risk factors for functional decline.

OBJECTIVES: To examine whether five major personality traits are related to the motoric cognitive risk (MCR) syndrome, a pre-dementia syndrome characterized by cognitive complaints and slow gait speed. DESIGN: Cross-sectional. SETTING: Health and Retirement Study (HRS) and the National Health and Aging Trends Survey (NHATS). PARTICIPANTS: Dementia-free older adults aged 65 to 107 years (N > 8000). MEASUREMENTS: In both samples, participants provided data on personality, cognitive complaints, and measures of gait speed, as well as on demographic factors, physical activity, depressive symptoms, and body mass index (BMI). RESULTS: Across the two samples and a meta-analysis, higher neuroticism was related to higher risk of MCR (combined odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.21-1.45; P < .001), whereas higher extraversion (combined OR = .71; 95% CI = .65-.79; P < .001) and conscientiousness (combined OR = .70; 95% CI = .62-.78; P < .001) were associated with a lower likelihood of MCR. Higher openness was also related to a lower risk of MCR in the HRS and the meta-analysis (combined OR = .77; 95% CI = .70-.85; P < .001), whereas agreeableness was protective only in the HRS (OR = .83; 95% CI = .74-.92; P < .001). Additional analyses indicated that physical activity, depressive symptoms, and BMI partially accounted for these associations. CONCLUSION: This study adds to existing research on the factors related to the risk of MCR by showing an association with personality traits. Personality assessment may help to identify individuals who may be targeted by interventions focused on reducing the risk of MCR and ultimately of dementia. J Am Geriatr Soc 68:803-808, 2020.

OBJECTIVES: Falls can have catastrophic consequences, especially for older adults. This study examined whether personality traits predict the incidence of falls in older age. METHOD: Participants were older adults aged from 65 to 99 years (N = 4,759) drawn from the Health and Retirement Study. Personality traits and demographic factors were assessed at baseline. Falls were tracked for up to 11 years. RESULTS: Over the follow-up period, 2,811 individuals reported falls. Cox regression analyses that included demographic covariates indicated that lower conscientiousness and higher neuroticism increased the risk of falling. Disease burden, depressive symptoms, and physical inactivity mediated the associations between both traits and falls incidence, whereas smoking status and handgrip strength mediated the neuroticism-falls incidence association. DISCUSSION: This study provides new prospective evidence that personality predicts the incidence of falls in older adults and suggest that personality assessment may help identifying individuals at higher risk of falling.
