Personality and Other Lifelong Influences on Older-Age Health and Wellbeing: Preliminary Findings in Two Scottish Samples

Determinants of Lifestyle Choices Among South Korean College Students: An Experimental Analysis

Purpose

Based on theoretical predictions from human capital theory, the aim of this exploratory study is to analyze the relationship between experimentally elicited, incentivized economic preference parameters, Big Five and Grit personality traits, cognitive ability, and the Alameda Seven lifestyles: smoking, drinking excessively, being overweight or obese, experiencing stress, following a healthy diet, exercising, and sleeping enough. In addition, self-reported general physical and mental health are analyzed.

Materials and Methods

Data collection took place in an incentivized paper-and-pencil experiment. Undergraduate students were recruited as subjects, with the requirement that they be freshmen, but no restrictions based on gender, major, or age. A pre-test and three experimental sessions were conducted in March and in April 2018, with a total of 178 subjects participating. After deleting observations with missing values, a total of n = 138 subjects remained. Regression analysis (multivariate probit models, resulting marginal effects and changes in predicted probabilities of adopting a lifestyle for “ideal types”) was used to analyze and compare the determinants of the Alameda Seven health behaviors.

Results

Findings suggest that preference parameters, a measure of cognitive ability, and Big Five personality traits are statistically significantly estimated in regressions for the determinants of adopting Alameda Seven health behaviors, but the Grit score is only statistically significantly estimated in a regression for the determinants of reported better general mental health.

Conclusion

The findings regarding preference parameters partly lend support to predictions from human capital theory and partly confirm previous findings in health psychology. Those results might be explained by the relatively small sample size and the inclusion of a measure of cognitive ability in addition to personality traits and preferences.

Gender differences in the relationship between personality, cognitive function and regular dental visits in Japanese community-dwelling older adults

OBJECTIVES

Studies have examined the association between personality and health behaviour, but research focusing exclusively on regular dental visits has yet to be conducted. This study examined the association between personality traits and regular dental visits among Japanese community-dwelling older adults.

METHODS

The participants in this cross-sectional study included 1,057 community-dwelling older adults aged 65-74 years from Ranzan and Yoshimi towns; data were collected from October to November 2015 and October to November 2016, respectively. Interviews were conducted to obtain sociodemographic, income, occupation and medical data. The Tokyo Metropolitan Institute of Gerontology Index of Competence was used to assess higher-level competence; general intelligence was also evaluated. The 'Big Five' personality traits-openness to experience, consciousness, neuroticism, extraversion and agreeableness-were also examined. A multivariable logistic regression analysis was performed to examine the relationship between regular dental visits and personality traits.

RESULTS

Among men, the number of natural teeth, current employment status and conscientiousness were associated with dental care utilization. Among women, the number of natural teeth, current annual income, the intellectual activity domain of the Tokyo Metropolitan Institute of Gerontology Index of Competence and openness were significant.

CONCLUSIONS

The factors associated with regular dental visits differed by gender. Overall, work was associated with men's visits, whereas intellectual activity and economic factors were relevant to women. Factors such as personality traits should be considered when addressing barriers to oral health. Understanding personality traits will help practitioners more effectively encourage older adults to make dental visits.

Factors Associated With Positive Self-Rated Health: Comparing Older Adults in Brazil and in Portugal

Introduction: Self-rated health is a multidimensional health indicator and a predictor of adverse events in old age. Answers to this assessment are influenced by social, cultural and personality factors. Aim: Exploring common and distinctive characteristics of Brazilian and Portuguese older adults aged 70 and over regarding positive self-rated health according to sociodemographic variables, to functional capacity, to independent performance of basic activities of daily living and to neuroticism, as well as analyzing associations between positive self-rated health and these variables. Methods: The present paper is a comparative and cross-sectional study based on secondary data contained in the databases of the FIBRA (Frailty in Brazilian Older Adults) follow-up study, with 418 Brazilian older adults, and of the DIA (From Disability to Activity: The Challenge of Aging) study, with 380 Portuguese older adults. Both samples had higher percentages of women: 68.4% for Portugal and 69.9% for Brazil. The Brazilian sample had a higher average age (80.31 ± 4.67) than the Portuguese sample (76.80 ± 5.28). Results: The Portuguese older adults had better overall cognition scores, higher handgrip strength and higher neuroticism values than the Brazilian older adults. In the simple and multiple logistic regression analyses, it was found that among Brazilian older adults, subjects with higher scores in the MMSE (OR 1.16; 95% CI 1.08-1.24), regardless of ADL performance (OR 2.13; 95% CI 1.31-3.47) and with scores 24-29 (OR 1.92; 95% CI 1.07-3.43) or 11-23 (OR 2.09; 95% CI 1.15-3.79) in neuroticism were more likely to assess their health as very good/good. On the other hand, the Portuguese older adults with intermediate 24-9 (OR 2.38; 95% CI 1.31-4.33) or low 11-23 (OR 5.31; 95% CI 2.69-10.45) scores in neuroticism were more likely to evaluate their health as very good/good. Conclusion: Based on the findings of the present study and on the existing literature, it may be said that it is possible for people to age while keeping a positive perception of their own health, even in advanced old age; comparisons between the above-mentioned countries, however, point to the need for investments in healthcare systems so that older adults may enjoy greater physical independence and improved mental health.

Testing a One-Item Risk Measure to Predict Alameda Seven Health Behaviors in the Republic of Korea

The college years provide an important window of opportunity for the implementation of preventive efforts, especially with respect to smoking, problematic drinking, and obesity. Targeting of individuals at high risk of adopting those health behaviors might increase the effectiveness of those efforts, yet little is known about possible criteria for targeting and their ability to predict the adoption of risky health behaviors. Human capital theory predicts that more risk-averse individuals are more likely to invest in their health capital and should therefore be less likely to engage in risky health behaviors. Building on this theoretical prediction, this study uses a simple one-item measure of risk attitude and examines its ability to predict the Alameda Seven health behaviors in a sample of college students in the Republic of Korea. Unlike previous research, it also controls for personality traits and cognitive ability. Experimental data were gathered and analyzed using regression analysis. The risk measure predicted the probability of smoking and reporting higher stress levels, with no correlations found for the other health behaviors, suggesting that replication studies using larger samples should be carried out to analyze if these findings persist.

Flexibility as a Mediator between Personality and Well-Being in Older and Younger Adults: Findings from Questionnaire Data and a Behavioral Task

BACKGROUND

Personality is a predictor of subjective well-being in older and younger adults, but less is known about the underlying mechanisms. One possible mechanism is psychological flexibility, which is the ability to keep an open mind-set in order to make flexible choices adapted to the situation at hand.

METHODS

We recruited 60 younger and 60 older adults and measured personality and well-being by questionnaires. To assess psychological flexibility we used questionnaires and a behavioral task assessing flexibility in information acquisition when making choices.

RESULTS

Based on indirect effect analysis of the questionnaire data, in line with former research, our data show that in both age groups, the relationship between personality and well-being runs through psychological flexibility.

CONCLUSION

This implies that training psychological flexibility may be a promising approach to increase well-being in both older and younger adults. This effect could not be demonstrated with our choice flexibility task, thus more research is needed to uncover why this could not be measured at the behavioral level.

Effects of "Thursdays at the Museum" at the Montreal Museum of Fine Arts on the mental and physical health of older community dwellers: the art-health randomized clinical trial protocol

Background

Recently, we demonstrated that the Montreal Museum of Fine Arts’ (MMFA) participatory art-based activity, known as “Thursdays at the Museum,” improved the well-being, quality of life, and physical health (i.e., frailty) of older community dwellers by using a pre-post intervention, single arm, prospective and longitudinal experimental design. The present randomized clinical trial (RCT), known as the Art-Health RCT (A-Health RCT), aims to compare changes in well-being, quality of life, frailty, and physiological measures in older community dwellers who participate in “Thursdays at the Museum” (intervention group) and in their counterparts who do not participate in this art-based activity (control group).

Methods/design

The current unicenter, randomized, clinical, controlled, comparative trial recruits 150 older community dwellers to two parallel arms (75 participants in the intervention group and 75 participants in the control group). The intervention is a 3-month cycle of weekly “Thursdays at the Museum,” which are structured 2-h-long art-based workshops performed in a group setting at the MMFA. The control group is composed of participants who do not take part in art-based activities, receive their usual health and/or social services, and commit to report any other activity practiced during the same time. Assessments of the primary outcome (well-being) and the secondary outcomes (quality of life, frailty, and physiological measures including heart rate, daily step count, sleep duration, and its phases) are performed on six occasions: at baseline, at the beginning of the second and third months, at the end of the third month, as well as 6 and 12 months after the last workshop. Statistical analyses are performed with the intention to treat and per protocol. Comparisons of changes in outcome measures between intervention and control groups use repeated measures tests.

Discussion

Art-based activities carried out at museums have been receiving increased interest from researchers and policy-makers because of their benefits to mental and physical health. There are few robust studies, such as RCTs, that focus on older community dwellers or assess the efficacy of these participatory museum activities. The A-Health RCT study provides an opportunity to confirm the benefits of a participatory art-based museum activity on the elderly population and to show the key role played by museums in public health promotion.

Personality traits and cognitive function in old-adults with type-2 diabetes

Objectives: Personality may constitute an important domain of influence on cognitive function in old-adults. We assessed the relationship of personality traits and cognitive performance in individuals with Type-2 Diabetes (T2D), and explored possible mediators. Method: The sample includes 377 dementia-free subjects with T2D participating in the Israel Diabetes and Cognitive Decline study who underwent assessment of cognition and personality (mean age 72 ± 4y; 42% females). We assessed the relationships of personality traits with episodic memory, semantic categorization, attention/working memory, executive function and overall cognition using linear regression models adjusting for age, education, sex, BMI, T2D duration, Hemoglobin A1C (HbA1C), hypertension, c-reactive protein, total- to HDL-cholesterol ratio and ApoEɛ4 genotype. A post-hoc mediation analysis was conducted with HbA1C, proportion of days covered (PDC) by T2D prescription claims and depressive symptoms. Results: After adjustment for multiple covariates, high neuroticism levels were associated with poorer performance overall (β= -0.16 ± 0.05; p = 0.001) and with poorer episodic memory, attention/working memory, and semantic categorization (β= -0.14 ± 0.05; p = 0.007, β= -0.12 ± 0.05; p = 0.017 and β= -0.12 ± 0.05; p = 0.018, respectively). High scores on openness to experience were associated with better global cognition (β = 0.11 ± 0.05; p = 0.026), executive functions (β = 0.13 ± 0.05; p = 0.013) and semantic categorization (β = 0.17 ± 0.05; p = 0.001, respectively). Depressive symptoms mediated the association of neuroticism with executive function, and the association of openness with executive function and overall cognition. Conclusion: Personality may play an important role in cognitive health among elderly subjects with T2D. Future studies should address the mechanisms underlying these relationships and specifically the potential role of depressive symptoms which may be in the causal pathway between personality traits and cognitive outcomes.

How is personality related to well-being in older and younger adults? The role of psychological flexibility

OBJECTIVES

Personality is known to be a reliable predictor of well-being. However, it is rather difficult to influence the personality of individuals in order to improve their well-being. Therefore, it is important to examine possible underlying mechanisms or indirect effects. Consequently, the aim of the current study was to investigate whether psychological flexibility is a mechanism explaining the relationship between personality and well-being. Given the evidence that age-related differences exist in personality, flexibility, and well-being, we also investigated whether our indirect effects model differed in both older and younger adults.

DESIGN

We used a cross-sectional design.

SETTING

Participants were asked to fill in questionnaires at home.

PARTICIPANTS

We recruited 138 younger (25-50 years) and 120 older (65+) adults from a community-dwelling population.

MEASUREMENTS

Self-report questionnaires were used to assess (mal)adaptive personality traits (Big Five), psychological flexibility, and affective and general subjective well-being.

RESULTS

Similar indirect effects were found in older and younger adults: Psychological flexibility is a mechanism explaining the link between personality and well-being. In nearly half of the models, psychological flexibility even fully accounted for the effect of personality on well-being.

CONCLUSION

These results have important implications for clinical practice, since psychological flexibility, contrary to personality traits, is malleable. Interventions to increase psychological flexibility already exist and are validated in both older and younger samples. They may hold promise to improve well-being.

The Mediating Effect of Self-Efficacy in the Connections between Strength-Based Parenting, Happiness and Psychological Distress in Teens

Preliminary studies of strength-based parenting (SBP), a style of parenting that seeks to build strengths knowledge and strengths use in one’s child, have reported benefits such as higher life satisfaction, subjective wellbeing, and positive emotions together with lower stress in children and teens. Two proximal mediators conveying these effects have been identified: teen’s own use of strengths and strength-based coping, along with a small moderating effect of growth mindsets relating to strengths. The current study tests the potential mediating effect of self-efficacy, a sense of agency in life, in the relationship between SBP and mental health (wellbeing and illbeing) in teens. Self efficacy has been linked to wellbeing and strengths processes in past studies and is classed as a basic human need and form of eudaimonic happiness. This study reconfirmed the adaptive benefits of SBP in a large sample of Australian adolescents (N = 11,368; 59% male; M_age = 14.04, SD_age = 1.99) sourced from 28 schools. Using structural equation modeling, SBP significantly and directly predicted higher happiness and lower depression, with direct effects falling into the 85th and 95th percentile of meta-analytically derived individual differences effect sizes. In addition, self-efficacy was a significant partial mediator, accounting for 40.0% of the total effect on happiness and 52.7% of the total effect on distress. Self-efficacy was also a full mediator in the case of anxiety, with a strong indirect effect. Results suggest that building strengths in teens can also build self-efficacy, and given the large effect sizes, that SBP is a promising leverage point for increasing teen wellbeing.

Personality and Other Lifelong Influences on Older-Age Health and Wellbeing: Preliminary Findings in Two Scottish Samples

Recent observations that personality traits are related to later-life health and wellbeing have inspired considerable interest in exploring the mechanisms involved. Other factors, such as cognitive ability and education, also show longitudinal influences on health and wellbeing, but it is not yet clear how all these early-life factors together contribute to later-life health and wellbeing. In this preliminary study, we assessed hypothesised relations among these variables across the life course, using structural equation modelling in a sample assessed on dependability (a personality trait related to conscientiousness) in childhood, cognitive ability and social class in childhood and older age, education, and health and subjective wellbeing in older age. Our models indicated that both health and subjective wellbeing in older age were influenced by childhood IQ and social class, via education. Some older-age personality traits mediated the effects of early-life variables, on subjective wellbeing in particular, but childhood dependability did not show significant associations. Our results therefore did not provide evidence that childhood dependability promotes older-age health and wellbeing, but did highlight the importance of other early-life factors, particularly characteristics that contribute to educational attainment. Further, personality in later life may mediate the effects of early-life factors on health and subjective wellbeing. © 2016 The Authors.
