Physical activity and personality development across adulthood and old age: Evidence from two longitudinal studies

Exploring the impact of physical activity on resilience: A longitudinal analysis in Japanese adults

Recently, the role of physical activity in enhancing resilience has garnered increasing attention. Resilience describes the personal characteristics that influence psychological recovery and adaptation to stress. This study examined the relationships between various domains of physical activity and resilience in Japanese adults by analyzing panel data from five waves, gathered at 3-month intervals over a year. The study included 579 Japanese adults, with an average age of 46.4 years (SD = 8.0, range = 30-59 years). Results from random effects models revealed a positive association between work-related moderate-to-vigorous physical activity (MVPA) and innate resilience factors. In contrast, sedentary behavior was negatively associated with these factors. Transport- and leisure-related MVPA showed positive correlations with acquired resilience factors. These findings show that the influence of physical activity on resilience may vary across different activity and resilience domains. Therefore, designing targeted interventions based on physical activity types is necessary for enhancing resilience.

Running, walking, and cross-country skiing: how to shape adolescents' personalities through physical activity?

Adolescence is crucial for personality development, and sports play a significant role. This study investigates the impact of various sports on the personality traits of junior high and high school students in Shandong Province, focusing on neuroticism, extraversion, openness, agreeableness, and conscientiousness. Utilizing data from the "Database of Youth Health," we employed Seemingly Unrelated Regression (SUR) and Generalized Structural Equation Modeling (GSEM) to analyze the effects of physical activity on personality development. Findings reveal that walking significantly enhances openness and decreased neuroticism, while jogging/running substantially improves extraversion, agreeableness, and conscientiousness. Cross-country skiing, however, negatively impacts all assessed personality traits. In addition, the importance of gender differences in the relationship between physical activity and personality development was revealed. The results offer insights for promoting adolescent personality development through targeted sports activities.

Physical, cognitive, and social activities as mediators between personality and cognition: evidence from four prospective samples

OBJECTIVES

The present study examined how activity engagement mediates the association between personality and cognition.

METHODS

Participants were middle-aged and older adults (Age range: 24-93 years; N > 16,000) from the Midlife in the United States Study, the Health and Retirement Study, the English Longitudinal Study of Ageing, and the Wisconsin Longitudinal Study of Aging. In each sample, personality traits and demographic factors were assessed at baseline, engagement in cognitive, physical, and social activities was assessed in a second wave, and cognition was measured in a third wave, 8 to 20 years later.

RESULTS

Random-effect meta-analyses indicated that lower neuroticism and higher extraversion, openness, and conscientiousness were prospectively associated with better cognition. Most of these associations were partly mediated by greater engagement in physical and cognitive activities but not social activities. Physical activity accounted for 7% (neuroticism) to 50% (extraversion) and cognitive activity accounted for 14% (neuroticism) to 45% (extraversion) of the association with cognition.

CONCLUSION

The present study provides replicable evidence that physical and cognitive activities partly mediate the prospective association between personality traits and cognitive functioning.

Searching for the perfect goalkeeping personality. Myth or reality?

Background

Psychological factors such as personality characteristics are influential factors of the goalkeeping performance in football (soccer). Not only for individualized treatment in practice, also from a scientific point of view, profiling goalkeepers is a relevant part of understanding athletes. The aim of this study was to investigate personality traits of goalkeepers of different expertise, age, and sex.

Methods

Using the Five Factor Model of personality we assessed personality traits of 132 male and female football goalkeepers ranging from youth to senior and low to elite level. A series of analysis investigated differences between the groups focusing on expertise, age, and sex.

Results

Significant differences in the personality trait agreeableness between groups of different expertise and sex could be detected. Although a significant difference in neuroticism levels of males and females could be shown.

Conclusion

This study was a first step of profiling football goalkeepers of different expertise, age, and sex. The study calls for more replication in this specific field of football and goalkeeping in general to understand the influence of personality characteristics on sport performance.

Personality and change in physical activity across 3-10 years

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.

Beyond Big Five trait domains: Stability and change in personality facets across midlife and old age

OBJECTIVE

Accumulated evidence indicates both stable and malleable parts of inter-individual differences in the broad Big Five domains. Less is known, however, about stability and change at the more diversified facet level. With the current study, we fill this gap by investigating personality stability and change across midlife and old age.

METHOD

We apply local structural equation measurement models and second-order growth curve models to four waves of data obtained with the full NEO Personality Inventory (NEO-PI-R) collected over 11 years from 1667 adults (Mage  = 62.69 years, SDage  = 15.62, 55% female) who participated in the Seattle Longitudinal Study.

RESULTS

Measurement invariance analyses indicated that the psychometric properties of the NEO-PI-R facets are comparable across time and age. Results revealed substantial rank-order stabilities across all facets, yet the exact pattern varied strongly between facets of the same trait and across traits. Mean-level change of facets from midlife to old age largely mirrored the mean-level change observed for the broader traits.

CONCLUSION

We discuss conceptual implications and argue that in the face of overall stability across midlife and old age, changes in the rank-ordering of people reveals a much more complex and diverse pattern of development than analyses at the trait level suggest.

Association of personality with habituation of physical and non-physical activities among Japanese adults: Results from questionnaire research before COVID-19 pandemic

Background

Physical activity has benefits for public health as it reduces the risk of non-communicable diseases and improves the quality of life. Previous studies have shown that health conditions, lifestyle, and socioeconomic status influence one's tendency to engage in physical activity. However, the influence of psychological traits on engagement in physical activity is not yet fully understood. In this study, we explored personality traits associated with the habituation of physical activity and compared them with personality traits associated with the habituation of non-physical activity.

Methods

We recruited 1600 Japanese adult volunteers and conducted an online survey just before the spread of COVID-19. We collected data for the prevalence of physical and non-physical activities, and various aspects of personality traits including the Big Five personality traits, sensitivity to behavioral activation, dark triad personality, levels of internal locus of control, and the degree of just-world belief.

Findings

The results demonstrated that high levels of extraversion, sensitivity to behavioral activation, and an internal locus of control had a positive influence on the habituation of physical activity. Moreover, our results were contradictory as they also showed that high levels of openness, sensitivity to behavioral activation, and just world belief related to the habituation of non-physical activity.

Interpretation

These results suggest that the personality traits that influenced the habituation of activities depend on the characteristics of the activity and reveal extraversion and internal locus of control as the personality traits specific to the habituation of physical activity.

IQ in Adolescence and Cognition over 50 years later: The Mediating Role of Adult Personality

There is substantial evidence for the association between higher early life IQ and better cognition in late life. To advance knowledge on potential pathways, the present study tested whether Five-Factor Model personality traits in adulthood mediate the association between adolescent IQ and later-life cognition. Participants were from the Graduate sample of the Wisconsin Longitudinal Study on Aging (WLS; N= 3,585). IQ was assessed in 1957 (about age 17), personality was assessed in 2003-2005 (age = 64), and cognition was assessed in 2011 (age = 71). Controlling for demographic factors, higher IQ in adolescence was related to higher openness, lower neuroticism, lower extraversion, lower agreeableness and lower conscientiousness in adulthood. Higher openness partially mediated the association between higher IQ and better cognition. Additional analyses indicated that the pattern of associations between IQ, personality and cognition was similar when the polygenic score for cognition was included as an additional covariate. Although effect size were small, this study provides new evidence that openness in adulthood is on the pathway between early life IQ and later-life cognition.

The transition to grandparenthood: No consistent evidence for change in the Big Five personality traits and life satisfaction

Intergenerational relations have received close attention in the context of population aging and increased childcare provision by grandparents. However, few studies have investigated the psychological consequences of becoming a grandparent. In a preregistered test of grandparenthood as a developmental task in middle and older adulthood, we used representative panel data from the Netherlands ( N = 563) and the United States ( N = 2210) to analyze first-time grandparents’ personality and life satisfaction development. We tested gender, employment, and grandchild care as moderators. To address confounding, we employed propensity score matching using two procedures: matching grandparents with parents and nonparents to achieve balance in different sets of carefully selected covariates. Multilevel models demonstrated mean-level stability of the Big Five personality traits and life satisfaction over the transition to grandparenthood, and no consistent moderation effects—contrary to the social investment principle. The few small effects of grandparenthood on personality development did not replicate across samples. We found no evidence of larger inter-individual differences in change in grandparents compared to the controls or of lower rank-order stability. Our findings add to recent critical re-examinations of the social investment principle and are discussed in light of characteristics that might moderate grandparents’ personality development.

The relationship between Big Five Personality Traits, eating habits, physical activity, and obesity in Indonesia based on analysis of the 5th wave Indonesia Family Life Survey (2014)

This study investigated the association between Big Five Personality Traits (Openness to new experience, Conscientiousness, Extraversion, Agreeableness, Neuroticism) and nutrition-related variables (eating habits, physical activity, and obesity using Body Mass Index). We used secondary data from the Indonesia Family Life Survey (IFLS) wave 5 involving a total of 14,473 men and 16,467 women aged 15-101 years (mean = 37.34; SD = 14.916) in Indonesia that was selected by stratified random sampling conducted in the period 2014 to 2015. Data were collected through interviews with the Big Five Index 15 and a questionnaire similar to the Global Physical Activity Questionnaire which was translated into the Indonesian language, and based on measurements of height and weight. Analyses used binary logistic regression test controlled by socio-demographic factors (age, gender, education, occupation, and marital status) to determine the association between Big Five Personality Traits and eating habits (recommended and non-recommended foods), physical activity, and obesity. Results showed that openness and extraversion were positively associated with recommended and non-recommended foods, conscientiousness was positively associated with only recommended foods, agreeableness was positively associated with recommended foods, and negatively associated with only one non-recommended food. Whereas, neuroticism was positively associated with non-recommended foods and negatively associated with recommended foods. Openness (p = 0.010; OR = 1.015; 95% CI = 1.004-1.027) and conscientiousness (p < 0.001; OR = 1.045; 95% CI = 1.030-1.059) were associated with physical activity. Conscientiousness (p = 0.002; OR = 1.025; 95% CI = 1.009-1.041), extraversion (p < 0.001; OR = 1.079; 95% CI = 1.065-1.092), and neuroticism (p < 0.001; OR = 0.966; 95% CI = 0.953-0.978) were associated with obesity. Although some results were different from previous studies, these associations can be used as strategies of behavioral change due to the adaptation of personality characteristics, which can be modified even though the personality tends to be persistent. Further studies are needed to understand other mechanisms that might underlie this association.

The Influence of Physical Exercise on Adolescent Personality Traits: The Mediating Role of Peer Relationship and the Moderating Role of Parent-Child Relationship

Adolescence is the critical period of the formation for individual personality traits, which would be influenced by numerous factors such as the internal and external environment. In view of physical exercise as an important factor affecting the healthy development of adolescents, whether it would play an important role in the formation of adolescents' personality traits and how it would work deserve further investigation. Based on the Ecological Systems Theory, this study has explored the relationship between physical exercise and adolescents' personality traits, as well as the mediating effect of peer relationship and the moderating effect of parent-child relationship using 9,284 data samples. The regression results show that physical exercise has a significant positive impact on the development of personality traits such as neuroticism, conscientiousness, and agreeableness. Peer relationships exert the mediating effect between physical exercise and adolescents' personality traits. However, parent-child relationship only moderates the effect of physical exercise on conscientiousness and agreeableness.

No Evidence for a Boost in Psychosocial Functioning in Older Age After a 6-Months Physical Exercise Intervention

The beneficial effects of physical exercise on physical health and cognitive functioning have been repeatedly shown. However, evidence of its effect on psychosocial functioning in healthy adults is still scarce or inconclusive. One limitation of many studies examining this link is their reliance on correlational approaches or specific subpopulations, such as clinical populations. The present study investigated the effects of a physical exercise intervention on key factors of psychosocial functioning, specifically well-being, stress, loneliness, and future time perspective. We used data from healthy, previously sedentary older adults (N = 132) who participated in a 6-month at-home intervention, either engaging in aerobic exercise or as part of a control group who participated in foreign language-learning or reading of selected native-language literature. Before and after the intervention, comprehensive cardiovascular pulmonary testing and a psychosocial questionnaire were administered. The exercise group showed significantly increased fitness compared to the control group. Contrary to expectations, however, we did not find evidence for a beneficial effect of this fitness improvement on any of the four domains of psychosocial functioning we assessed. This may be due to pronounced stability of such psychological traits in older age, especially in older adults who show high levels of well-being initially. Alternatively, it may be that the well-documented beneficial effects of physical exercise on brain structure and function, as well as cognition differ markedly from beneficial effects on psychosocial functioning. While aerobic exercise may be the driving factor for the former, positive effects on the latter may only be invoked by other aspects of exercise, for example, experiences of mastery or a feeling of community.

Personality Change Profiles and Changes in Cognition Among Middle-Aged and Older Adults

Research on the relationship between personality traits and cognitive abilities has primarily used cross-sectional designs and considered personality traits individually in relation to cognitive dimensions. This study (N = 2,652) examined the relationship between Big Five personality change profiles and change in cognitive factors, episodic memory and executive functioning. Latent profile analysis was used to capture patterns of change across the Big Five traits. Three profiles of personality change were defined: Decreasers, Maintainers, and Increasers. The Decreasers declined more in episodic memory compared to the Increasers and Maintainers. Also, the Decreasers declined more in executive functioning compared to the Increasers, but not the Maintainers. The findings advance our understanding of the links between patterns of personality change and cognitive aging.

Relationship Between Mental Health, Resilience, and Physical Activity in Older Adults: A 2-Year Longitudinal Study

The aim of this study was to longitudinally investigate the association between resilience and mental health in older adults and to determine the influence of physical activity on this relationship. A total of 291 older adults were included in a 2-year follow-up study. Adjusted linear regression models evaluated the association between resilience at baseline and mental health after 2 years in sufficiently and insufficiently physically active older adults. A negative correlation was found between resilience at baseline and depression, anxiety, and stress after 2 years for the overall sample. This association changed after stratifying the group. Sufficiently physically active individuals made greater use of the resilience components "Self-Sufficiency" and "Perseverance," whereas insufficiently physically active individuals made greater use of "Meaning of Life" and "Existential Singularity." Physical activity can influence the relationship between resilience and mental health. These results can help guide the devising of more effective interventions for this age group.

Extraversion development in childhood, adolescence and adulthood: Testing the role of sport participation in three nationally-representative samples

This research sought to test whether sport participation relates to the development of trait extraversion across three life phases. Sport participation and extraversion were measured in children aged 10.5 ± 0.5 years (n = 3600), in adolescents aged 14.5 ± 0.5 years (n = 3463), and in adults with a mean age of 49.4 ± 18.0 years (n = 12,280), with corresponding data collected four years earlier. There were small mean-level decreases in extraversion during childhood and adulthood, and a large decrease in extraversion during adolescence. Four-year rank-order stability in extraversion was .58 in childhood, .61 in adolescence and .76 in adulthood. Sport participation was associated with higher extraversion in all three samples. After controlling for sociodemographic factors, children and adolescents who dropped out of sport showed greater decreases in extraversion than those who continued participation in sport. Sport participation was unrelated to mean-level change in extraversion during adulthood. Sport participation was also associated with greater intra-individual stability in extraversion for children, adolescents and adults. There were no significant sex moderation effects for mean-level change or individual-level stability. These findings provide evidence that sport participation might have an important role in trait extraversion stability and change across the lifespan.

Memory and Personality Development in Adulthood: Evidence From Four Longitudinal Studies

OBJECTIVES

Personality traits have been related to concurrent memory performance. Most studies, however, have focused on personality as a predictor of memory; comparatively less is known about whether memory is related to personality development across adulthood. Using 4 samples, the present study tests whether memory level and change are related to personality change in adulthood.

METHOD

Participants were drawn from 2 waves of the Wisconsin Longitudinal Study Graduates (WLSG; N = 3,232, mean age = 64.28, SD = 0.65) and Wisconsin Longitudinal Study Siblings (WLSS; N = 1,570, mean age = 63.52, SD = 6.69) samples, the Midlife in the United States (MIDUS; N = 1,901, mean age = 55.43, SD = 10.98), and the Health and Retirement Study (HRS; N = 6,038, mean age = 65.47, SD = 8.28). Immediate and delayed recall and the 5 major personality traits were assessed at baseline and follow-up.

RESULTS

There was heterogeneity in the associations across samples. A meta-analysis of latent change in the four samples indicated that lower baseline memory performance was related to an increase in neuroticism (B = -0.002; 95% CI = -0.004, -0.0008) and a decrease in agreeableness (B = 0.004; 95% CI = 0.002, 0.007) and conscientiousness (B = 0.005; 95% CI = 0.0008, 0.010). In addition, declines in memory were related to steeper declines in extraversion (B = 0.06; 95% CI = 0.003, 0.11), openness (B = 0.04; 95% CI = 0.007, 0.069), and conscientiousness (B = 0.05; 95% CI = 0.019, 0.09).

DISCUSSION

The present study indicates that poor memory and declines in memory over time are related to maladaptive personality change. These associations, however, were small and inconsistent across samples.

Physical activity and subjective age across adulthood in four samples

The present study examined the prospective association between physical activity and subjective age across adulthood and factors that mediate this association. Participants were adults aged from 20 to 90 years (N > 10,000) drawn from the Wisconsin Longitudinal Study graduates and siblings samples, the Health and Retirement Study and the Midlife in the United States Survey. In the four samples, physical activity was assessed at baseline and subjective age was measured 8 to 20 years later. Personality, self-rated health, disease burden, depressive symptoms, and cognition were assessed as potential mediators. In the four samples, higher physical activity at baseline was associated with a younger subjective age at follow-up. Logistic regression revealed that physical activity was related to a 30-50% higher likelihood of feeling younger 8 to 20 years later. Significant indirect effects were found through openness to experience and self-rated health in the four samples. This study provides new evidence on the link between a health-related behavior and subjective age. Physically active individuals may sustain health and an open psychological disposition that is associated with feeling younger.

Physical activity partially mediates associations between "Big" personality traits and incident generalized anxiety disorder: Findings from the irish longitudinal study on ageing

BACKGROUND

This study aimed to examine associations of personality with generalized anxiety disorder (GAD) and physical activity (PA), PA with GAD, and PA mediates associations between personality and incident GAD.

METHODS

Participants aged ≥50 years completed the 60-item NEO-Five Factor Inventory questionnaire to assess personality and short-form International Physical Activity Questionnaire at baseline, and the Composite International Diagnostic Interview - Short Form to clinically assess GAD at baseline and 2, 4, and 6 years later. Participants who had GAD at baseline or reported having ever been told by a doctor that they had anxiety were excluded from analyses. Binary logistic regression quantified associations of the 'Big Five' personality traits with PA and incident GAD, and associations of PA with incident GAD (i.e., GAD at any point during follow-up). The 'counterfactual approach' identified potential mediating effects of PA in the associations between personality traits and incident GAD.

RESULTS

Participants (n = 4582; 53.7% female) were aged 64.38±8.88 years. Incidence of GAD was 2.95% (n = 135). Extraversion (OR=1.160, 95%CI=1.087-1.237), openness (1.113, 1.043-1.188), and conscientiousness (1.083, 1.015-1.155) were positively associated with physical activity. Neuroticism was positively (2.335, 1.945-2.803), and extraversion (0.700, 0.563-0.797), conscientiousness (0.826, 0.693-0.985), and PA (0.655, 0.451-0.952) were inversely, associated with the incident GAD. Approximately 8.7% of the effect of extraversion and 8.8% of the effect of conscientiousness on GAD was due to mediation by PA only.

LIMITATIONS

PA was self-reported Conclusions: Personality screening may help to identify older adults at-risk of anxiety who would benefit from participation in physical activity interventions.

The Main Dimensions of Sport Personality Traits: A Lexical Approach

To uncover the main dimensions of sport personality traits, a lexical study was conducted. In the first two phases, 321 adjectives denoting the way somebody practices sports were selected. In the third phase, 555 respondents self-rated the adjectives. Congruence analyses provided evidence of six factors, five of which are sport personality trait factors (friendly fairness, resilience, drive, perfectionism, and inventiveness) plus one physical individual difference factor (agility). Marker scales from the sport personality trait factors show convergent correlations with the generic HEXACO personality obtained years earlier. Furthermore, meaningful relations with the six most frequently practiced sport and leisure activities were observed. Contextualized sport personality trait factors can be useful in research on sport preferences, sport behaviors, and sport outcomes.

Variety Is the Spice of Late Life: Social Integration and Daily Activity

OBJECTIVES

Social integration (involvement with a diverse array of social ties) has been linked to positive outcomes including better physical health. Research has not investigated whether encounters with diverse social ties enhance individuals' daily behaviors. The objectives of this study were to assess whether social ties connect individuals to more diverse daily behaviors, physical activity, and nonsedentary time as well as more positive mood.

METHOD

Older adults (aged 65+, n = 313) provided information about their 10 closest social ties. Then they completed ecological momentary assessment (EMA) surveys every 3 hr for 5-6 days where they reported on social encounters and behaviors. They also wore Actical accelerometers to objectively measure physical activity.

RESULTS

Multilevel models revealed that encounters with a greater variety of social ties was associated with engaging in a greater variety of behaviors, more objectively measured physical activity, and a smaller proportion of time spent sedentary. Encounters with weak ties/peripheral social ties accounted for this increased activity (compared to being alone or with close friends or family). Moreover, involvement with diverse ties or diverse behaviors was associated with better mood.

DISCUSSION

Findings are discussed in terms of social engagement theory, network diversity, and the benefits of weak ties.

Design and methods of a national, multicenter, randomized and controlled trial to assess the efficacy of a physical activity program to improve health-related quality of life and reduce fatigue in women with metastatic breast cancer: ABLE02 trial

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.

Change in weight and personality in middle-aged and older adults

Objective: Personality is associated with weight change and the development of obesity across adulthood. The present study examines whether significant weight change, including weight loss and weight gain, is related to personality change in a large longitudinal sample of middle-aged and older adults.Design: Participants were adults aged 50-92 years (N > 5000; 59% women, Mean age = 65.51, SD = 8.20) drawn from the Health and Retirement Study (HRS). Personality, demographic, health and staff assessed weight and height were obtained at baseline and 8 years later.Main Outcome Measures: Personality traits.Results: Both weight loss and weight gain greater than 10% of baseline weight were related to a steeper decline in extraversion, openness and conscientiousness. Weight loss was further associated with the maintenance of neuroticism and to a steeper decline in agreeableness. This overall pattern of personality change was also associated with both unhealthy and healthy weight change. The associations were not moderated by BMI and generally remained significant after accounting for disease burden.Conclusion: The present study provides new evidence that both weight loss and weight gain are related to change in personality.

Personality, disability-free life years, and life expectancy: Individual participant meta-analysis of 131,195 individuals from 10 cohort studies

OBJECTIVE

We examined how personality traits of the Five Factor Model were related to years of healthy life years lost (mortality and disability) for individuals and the population.

METHOD

Participants were 131,195 individuals from 10 cohort studies from Australia, Germany, the United Kingdom, and the United States (n = 43,935 from seven cohort studies for the longitudinal analysis of disability, assessed using scales of Activities of Daily Living).

RESULTS

Lower Conscientiousness was associated with higher mortality and disability risk, but only when Conscientiousness was below its median level. If the excess risk associated with low Conscientiousness had been absent, population life expectancy would have been 1.3 years longer and disability-free life 1.0 years longer. Lower emotional stability was related to shorter life expectancy, but only among those in the lowest 15% of the distribution, and disability throughout the distribution: if the excess risk associated with low emotional stability had been absent, population life expectancy would have been 0.4 years longer and disability-free life 2.4 years longer.

CONCLUSIONS

Personality traits of low Conscientiousness and low emotional stability are associated with reduced healthy life expectancy of individuals and population.

Physically active undergraduates: Motivational and emotional profiles

Objectives: The aim was to determine the motivational profiles - including variables from the theory of self-determination and emotional intelligence - of active undergraduates, and to examine their relationship with physical activity. Participants: Six hundred and fifteen undergraduates participated in the study. Methods: Trait Meta-Mood Scale, Basic Psychological Needs in Exercise Scale, Behavioral Regulation in Exercise Questionnaire and Habitual Physical Activity Questionnaire were administered. Cluster analysis was used to identify the motivational profiles. Results: Two motivational profiles were found. One of the motivational profiles included the participants with high levels of satisfaction of the basic psychological needs and self-determined motivation; moderately high levels of emotional clarity and repair; and low levels of non-self-determined motivation. Further, this group showed the highest rates of physical practice than its counterpart. Conclusions: The combination of self-determination theory and emotional intelligence should be considered when examining adherence to physical activity.

Extraversion personality, perceived health and activity participation among community-dwelling aging adults in Hong Kong

Activity participation is essential to the wellbeing of aging adults. Divergent levels of activity participation within aging populations have been explained from diverse perspectives, but the interaction effects of key determinants, such as personality and health, are often ignored. This study examines the effects of extravert personality on aging adults' activity levels by addressing its interaction with perceived physical health and mental health. A sample of 304 adults aged 50 and older was selected using systematic sampling from participants of an institute for promoting active aging at a university in Hong Kong in 2017. Data on socio-demographic characteristics, perceived physical and mental health, extraversion personality traits, and level of activity participation were collected using a telephone survey. Most participants (46.7%) reported moderate activity levels and over a quarter (26.6%) reported high or low activity levels. Multi-nominal logistic regression analyses show that extraversion was associated with an increased likelihood of reporting moderate (OR = 1.85, p = .036) but not high (p > .05) activity levels when adjusted for perceived physical and mental health and socio-demographics, with low activity levels being the constant comparison. Meanwhile, extraversion predicted both moderate (OR = 3.84, p = .014) and high (OR = 5.06, p = .032) activity levels for participants with poor or average perceived mental health. However, the interaction effects of extraversion with perceived physical health or mental health were not significant in predicting either moderate or high activity levels (p > .05). The implications for enhancing activity participation among aging adults are discussed in view of both personality and perceived health status.

Alcohol use and personality change in middle and older adulthood: Findings from the Health and Retirement Study

OBJECTIVE

Personality is known to predict alcohol consumption, but how alcohol use is related to personality change is less clear, especially at older ages. The present study examined the effects of level of alcohol consumption and history of dependence on change in the Five-Factor Model personality traits in a national cohort of Americans aged over 50.

METHOD

Over 10,000 adults who participated in 2006-2008 waves of the Health and Retirement Study reported on personality and alcohol use and were followed over 4 years.

RESULTS

Latent difference score models indicated decreases in Extraversion to be attenuated for individuals categorized as light-to-moderate drinkers at baseline, whereas decreases in Conscientiousness were accentuated by having experienced alcohol dependence symptoms. Moreover, personality difference scores correlated with changes in the amount of alcohol consumed at follow-up.

CONCLUSIONS

The findings suggest that patterns of alcohol consumption are associated with changes in personality across the second half of the life span.

Activity Engagement and Activity-Related Experiences: The Role of Personality

Objectives

The associations of personality with activity participation and well-being have been well studied. However, less is known concerning the relationship between personality and specific aspects of activity engagement in older adults. We conducted a fine-grained examination of the effects of extraversion and conscientiousness on reported activity engagement-which we define as participation, time allocated, and affective experience-during 8 everyday activities.

Method

Data were obtained using a day reconstruction measure from a subgroup of participants in the 2012 Health and Retirement Study (HRS: N = 5,484; mean age = 67.98 years).

Results

We found mixed support for hypotheses suggesting that specific personality traits would be associated with activity participation, time allocated, and activity-affective experience. For example, extraverts were more likely to socialize and experienced higher socializing-related positive affect, but did not spend more time socializing.

Discussion

Results are discussed in light of the value of including personality in, and its contribution to, studies of activity engagement in later life. In addition, the need to acknowledge the complexity of the concept of activity engagement in future research is highlighted.

Loneliness effects on personality

Individuals feel lonely when they perceive a discrepancy between their desired and their actually experienced quantity and quality of social relationships. Prior research has demonstrated the importance of loneliness for various health-related aspects. In the present article, we extend the existing literature on loneliness by investigating its role for predicting personality traits and their development from late adolescence to early midlife. Using data from a representative German sample ( N = 12,402) sampling individuals from three different birth cohorts, we found loneliness to predict the levels of all Big Five traits except openness five years later. The effects of loneliness on the development of neuroticism and extraversion reached statistical significance but were only marginal in terms of effect size. Furthermore, we found that a self-regulatory focus geared to the prevention of negative events mediated the effects of loneliness on later levels of the Big Five.

Personality Across the Life Span

Trait stability and maturation are fundamental principles of contemporary personality psychology and have been shown to hold across many cultures. However, it has proven difficult to move beyond these general findings to a detailed account of trait development. There are pervasive and unexplained inconsistencies across studies that may be due to ( a) insufficient attention to measurement error, ( b) subtle but age-sensitive differences in alternative measures of the same trait, or ( c) different perspectives reflected in self-reports and observer ratings. Multiscale, multimethod-and ideally multinational-studies are needed. Several hypotheses have been proposed to account for trait stability and change, but supporting evidence is currently weak or indirect; trait development is a fertile if sometimes frustrating field for theory and research. Beyond traits, there are approaches to personality development that are of interest to students of adult development, and these may be fruitfully addressed from a trait perspective.

Exaggerated reaction to novelty as a predictor of incipient cognitive decline among community-dwelling older adults

OBJECTIVE

The ability to detect covert markers of incipient cognitive decline among older adults before cognitive decline becomes overtly evident on traditional cognitive tests represents an important topic of research. Exaggerated reactions to novelty, reflected in novelty-induced increases in action planning latencies ("novelty effect"; NE) and low openness to experience (openness), have been previously associated with incipient cognitive decline among older adults who appeared cognitively normal at baseline. The purposes of the present study were to extend prior research on the utility of these markers by examining whether (a) NE and openness each predict cognitive change uniquely, and (b) whether these indices predict cognitive change above and beyond measures of memory, executive functions, processing speed/efficiency, premorbid IQ, and depressive symptoms.

METHOD

Sixty-one cognitively normal community-dwelling older adults were administered a battery of tests assessing the relevant constructs at baseline and one-year follow up. Changes in cognitive status were assessed using the Demetia Rating Scale, 2nd Edition, NE was assessed using the Push-Turn-Taptap task (an electronic motor sequence learning task), and openness using the NEO Personality Inventory-Revised. The Test of Premorbid Functioning, and subtests from Repeatable Battery for the Assessment of Neuropsychological Status, Delis-Kaplan Executive Function System, and Wechsler Adult Intelligence Scale, 4th Edition, were used for additional assessment of baseline cognition. Depressive symptoms were assessed using the Geriatric Depression Scale.

RESULTS

Results confirmed our hypothesis that both NE and openness contribute to prediction of cognitive change beyond baseline cognition and depressive symptoms, but none of the covariates (i.e., depression, executive functions, processing efficiency, or memory) themselves contributed to the model. NE and openness each contributed unique variance and were independent of each other.

CONCLUSIONS

Openness and NE have the potential to provide evidence-based methods for estimating risk of future cognitive change in persons with currently normal standardized test scores.

Cognitive Impairment, Dementia, and Personality Stability Among Older Adults

There is contrasting evidence on personality stability in advanced age, and limited knowledge on the impact of cognitive impairment and dementia on trait stability. Group- and individual-level longitudinal analyses of the five major dimensions of personality assessed twice over 4 years ( N = 9,935) suggest that rank-order stability was progressively lower with advancing age (from rtt = 0.68 for age 50 to 60 years to rtt = 0.58 for age >80 years). Stability was low in the dementia group ( rtt = 0.43), and this was not simply due to lower reliability given that internal consistency remained adequate in the dementia group. Among individuals with no cognitive impairment or dementia, there was no association between stability and age ( rtt = 0.70 even for age >80 years). These results suggest that the lower personality stability in older adults is not due to age but cognitive impairment and dementia.

Physical Activity and Personality Development over Twenty Years: Evidence from Three Longitudinal Samples

A physically inactive lifestyle is associated with maladaptive patterns of personality development over relatively short follow-up periods. The present study extends existing research by examining whether this association persists over 20 years. Participants (total N = 8,723) were drawn from the Wisconsin Longitudinal Study Graduates and Siblings samples and the Midlife in the United States Study. Controlling for demographic factors and disease burden, baseline physical inactivity was related to steeper declines in conscientiousness in all three samples and a meta-analysis (β=-.06). The meta-analysis further showed that lower physical activity was associated with declines in openness (β=-.05), extraversion (β=-.03), and agreeableness (β=-.03). These findings provide evidence that a physically inactive lifestyle is associated with long-term detrimental personality trajectories.

Personality and Lung Function in Older Adults

OBJECTIVES

Lung disease is a leading cause of disability and death among older adults. We examine whether personality traits are associated with lung function and shortness of breath (dyspnea) in a national cohort with and without chronic obstructive pulmonary disease (COPD).

METHOD

Participants (N = 12,670) from the Health and Retirement Study were tested for peak expiratory flow (PEF) and completed measures of personality, health behaviors, and a medical history.

RESULTS

High neuroticism and low extraversion, openness, agreeableness, and conscientiousness were associated with lower PEF, and higher likelihood of COPD and dyspnea. Conscientiousness had the strongest and most consistent associations, including lower risk of PEF less than 80% of the predicted value (OR = 0.67; 0.62-0.73) and dyspnea (OR = 0.52; 0.47-0.57). Although attenuated, the associations remained significant when accounting for smoking, physical activity, and chronic diseases including cardiovascular and psychiatric disorders. The associations between personality and PEF or dyspnea were similar among those with or without COPD, suggesting that psychological links to lung function are not disease dependent. In longitudinal analyses, high neuroticism (β = -0.019) and low conscientiousness (β = 0.027) predicted steeper declines in PEF.

DISCUSSION

A vulnerable personality profile is common among individuals with limited lung function and COPD, predicts shortness of breath and worsening lung function.

Health-Related Behavior Mediates the Association Between Personality and Memory Performance in Older Adults

This prospective study explored the potential mediating role of health-related behavior (alcohol involvement, diet, television viewing, and physical activity) in the association between personality and change in memory performance over 2 years. A nationally representative sample of 8,376 U.K. participants aged 55 years and older (4,572 women, 3,804 men) completed self-report measures of personality and health-related behavior in 2010, and completed a memory performance task in 2010 and 2012. After removing variance associated with potential confounding variables, neuroticism and agreeableness had negative associations, and openness and conscientiousness positive associations with change in memory performance. There were no moderation effects by age, sex, education level, or ethnicity. Multiple mediator models demonstrated that physical activity, television viewing, and alcohol intake mediated associations between personality and change in memory performance. These findings provide evidence that the association between personality and memory performance in older adults can be explained, in part, through health-related behavior.

Personality and Frailty: Evidence From Four Samples

Frailty is a prevalent geriatric syndrome. Little is known about the psychological factors associated with this syndrome. Based on four large samples of older adults aged from 65 to 104 years old, the present study examined whether personality traits are related to frailty. High neuroticism, low conscientiousness, low extraversion, low openness and low agreeableness were related to higher frailty across samples. Longitudinal analysis conducted in one sample revealed that high neuroticism was associated with worsening frailty over an 8-year period. Higher frailty at baseline and over time was related to maladaptive personality changes. This study extends existing knowledge on the link between personality and health in older adults, by identifying the personality traits associated with frailty, a complex geriatric syndrome.

Allostatic Load and Personality: A 4-Year Longitudinal Study

OBJECTIVE

Dysregulation across multiple physiological systems, referred to as allostatic load, has pervasive consequences for an individual's health. The present study examined whether allostatic load is associated with personality and personality changes during a 4-year follow-up.

METHODS

A total of 5200 participants aged from 50 to 99 years (59.5% women, mean [standard deviation] age = 66.91 [8.88] years) from the Health and Retirement Study provided data on cardiovascular, metabolic, and immune markers at baseline and personality both at baseline and at 4 years later.

RESULTS

Higher allostatic load was related to higher neuroticism (β = 0.03, p = .042), lower extraversion (β = -0.06, p < .001), and lower conscientiousness (β = -0.06, p < .001) at baseline, and to declines in extraversion (β = -0.03, p = .007), conscientiousness (β = -0.04, p < .001), and agreeableness (β = -0.02, p = .020) over the 4-year period, controlling for demographic covariates. A significant quadratic relation between allostatic load and changes in openness (β = -0.03, p = .002) suggested that openness declines when individuals exceed a high level of cumulative physiological dysregulation. No association was found with changes in neuroticism.

CONCLUSIONS

Allostatic load is associated with personality change across adulthood and old age. The findings indicate that physiological dysregulation across multiple systems challenges personality stability and is associated with accelerated personality traits change.

Personality traits and body mass index: Modifiers and mechanisms

OBJECTIVE

To identify how demographic factors (sex, age, ethnicity) modify the association between personality traits and body mass index (BMI) and to test the extent that diet and physical activity account for the personality-BMI relations.

DESIGN

Cross-sectional study with a diverse sample (N = 5150, 50% female, 19% African American, 15% Hispanic). Participants completed a measure of the five major dimensions of personality and reported on their physical activity, diet and food intake behaviour, and height and weight.

MAIN OUTCOME MEASURES

BMI and obesity (BMI ≥ 30).

RESULTS

High Neuroticism was associated with higher BMI and risk for obesity, whereas Conscientiousness and, to a lesser extent, Extraversion and Openness were protective. These associations were generally stronger among women and older participants; there was less evidence for ethnicity as a moderator. Personality had similar relations with the behavioural factors, and physical activity, diet and regular meal rhythms accounted for approximately 50% of the association between Neuroticism and Conscientiousness and BMI.

CONCLUSION

This study supports the links between personality traits and BMI and suggests that physical activity, more than diet, is a key factor in these associations.

Sport participation, screen time, and personality trait development during childhood

This investigation explored the contribution of extracurricular sport and screen time viewing (television viewing and electronic gaming) to personality trait stability and change during childhood. Two independent samples of 3,956 young children (age 6) and 3,862 older children (age 10) were taken from the Longitudinal Study of Australian Children. Parent-reported child sport participation, screen time, and personality traits were measured at baseline and again 24 months later. Young children who were more active recorded more of a decrease in introversion, less of a decrease in persistence, and less of an increase in reactivity, than those who were less active. Older children who were more active recorded less of an increase in introversion and more of an increase in persistence than those who were less active. In addition, young children who continued participation in extracurricular sport had greater intra-individual stability of personality for introversion. These finding suggest that an active lifestyle might help to facilitate desirable personality trait stability and change during childhood.

The Winding Paths of the Lonesome Cowboy: Evidence for Mutual Influences Between Personality, Subjective Health, and Loneliness

Prior research demonstrated influences of personality traits and their development on later status of subjective health and loneliness. In the present study, we intended to extend these findings by examining mutual influences between health-related characteristics and personality traits and their development over time. German adults were assessed at two time points across 15 years (NT1  = 654, NT2  = 271; Mage at Time 1 = 24.39, SD = 3.69). Data were analyzed with multivariate structural equation models and a multivariate latent change model. Neuroticism was found to predict later levels and the development of subjective health and loneliness. While subjective health likewise predicted later levels of Neuroticism, loneliness was found to be predictive of later levels as well as the development of Neuroticism, Extraversion, and Conscientiousness. Correlated changes indicated that developing a socially more desirable personality is associated with slower declines in subjective health and slower increases in loneliness. The findings indicate that characteristics related to an individual's health are reciprocally associated with personality traits. Thus, the study adds to the understanding of the development of personality and health-related characteristics.

Emotional intelligence in sport and exercise: A systematic review

This review targets emotional intelligence (EI) in sport and physical activity. We systematically review the available literature and offer a sound theoretical integration of differing EI perspectives (the tripartite model of EI) before considering applied practice in the form of EI training. Our review identified 36 studies assessing EI in an athletic or physical activity context. EI has most often been conceptualized as a trait. In the context of sport performance, we found that EI relates to emotions, physiological stress responses, successful psychological skill usage, and more successful athletic performance. In the context of physical activity, we found that trait EI relates to physical activity levels and positive attitudes toward physical activity. There was a shortage of research into the EI of coaches, officials, and spectators, non-adult samples, and longitudinal and experimental methods. The tripartite model proposes that EI operates on three levels - knowledge, ability, and trait - and predicts an interplay between the different levels of EI. We present this framework as a promising alternative to trait and ability EI conceptualizations that can guide applied research and professional practice. Further research into EI training, measurement validation and cultural diversity is recommended.

The Role of Personality in Sport and Physical Activity

There is now good evidence that athletic success and participation in physical activity can be predicted by personality traits. In this article, we review new studies that have contributed to our understanding of these relationships and outline potential avenues of inquiry to support the development of personality-trait research in exercise and sport. Our review identified a number of novel findings from contemporary studies. In the context of sport performance, new studies have demonstrated that personality traits relate to long-term athletic success, interpersonal relationships, and athletes’ psychological states before, during, and after competitions. In the context of health-related exercise, new studies have demonstrated that personality traits relate to leisure-time sitting time, strength and mobility in old age, and unhealthy (addictive) exercise behaviors. There is also evidence that physical activity contributes to personality change. Our recommendations include a more targeted focus on adolescence (as this is the age of greatest change in personality and sport participation) and a greater consideration of consultant personality traits in applied research and professional practice (given their role in intervention effectiveness).
