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. 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 = 25,418). 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 = 0.88, 95\% CI [0.84-0.92]). Among participants who reported no falls at baseline ( = 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. 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.

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 ( > 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.

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{\textquoteright}s chronological age) and falls in two large national samples.

METHOD: Participants, aged 65 to 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, demographic factors, was 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.

OBJECTIVES: The motoric cognitive risk (MCR) syndrome, characterized by cognitive complaints and slower gait speed, is a pre-dementia 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.

METHOD: The study sample was composed of 6,341 individuals aged 65 to 107 years without dementia from the Health and Retirement Study (HRS), 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 four and eight 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.

CONCLUSION: 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.

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.

OBJECTIVES: Falls can have catastrophic consequences, especially for older adults. The present 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.

Past research has found an association between personality traits and self-rated health. However, there has not been a multi-cohort large-scale study that has examined this link, and few studies have examined the association between personality and change in self-rated health. Objective To examine the concurrent and longitudinal association between personality and self-rated health.MethodParticipants were individuals aged from 16 to 107 years (N> 46,000) drawn from eight large longitudinal samples from the US, Europe, and Japan. Brief measures of the five-factor model of personality, a single item measure of self-rated health, and covariates (age, sex, and education, and race) were assessed at baseline and self-rated health was measured again 3 to 20 years later. Results In cross-sectional analyses, higher neuroticism was related to lower self-rated health whereas higher extraversion, openness, agreeableness and conscientiousness were associated with better self-rated health across most samples. A meta-analysis revealed that a one standard deviation higher neuroticism was related to more than 50\% higher risk of fair to poor health, whereas a one standard deviation higher extraversion, openness, agreeableness and conscientiousness was associated with at least 15\% lower risk of fair or poor health. A similar pattern was found in longitudinal analyses: personality was associated with risk of self-rated excellent/very good/good health at baseline becoming fair/poor at follow-up. In multilevel analyses, however, personality was weakly related to trajectories of self-rated health and in the opposite of the expected direction. Conclusions The present study shows replicable cross-sectional and small longitudinal associations between personality and self-rated health.

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).
