Is Conscientiousness Always Associated With Better Health? A U.S.-Japan Cross-Cultural Examination of Biological Health Risk

The relationship between NEO-five personality traits and sleep-related characteristics: A systematic review and meta-analysis

An increasing body of research has suggested personality traits as a possible predisposing factor for individual differences in sleep pattern and problems. However, the findings were mixed and there remained a lack of a quantitative synthesis. As searched in the four databases (Web of Science, Embase, PsycINFO, PubMed), 60 studies (n = 73,540; female = 60 %) that used standardized measures to evaluate the relationship between NEO-five personality traits and sleep-related outcomes (sleep quality and sleep duration) were identified. Meta-analyses were performed using random-effects model and the results suggested that poor sleep quality was associated with a higher level of neuroticism (r = 0.287) but a lower degree of openness (r = -0.042), conscientiousness (r = -0.132), extraversion (r = -0.086), and agreeableness (r = -0.064). Shorter sleep duration was found to be associated with a higher level of neuroticism (r = 0.066) but not with other personality dimensions. The findings were mainly limited to the general population. Future research should investigate whether comparable patterns of associations are present in the clinical populations. There is also a need for more research with a prospective design utilizing objective sleep measurements and to explore the mechanisms underlying the association of personality factors with sleep-related characteristics, especially sleep quality and duration.

Personality matters: Exploring the associations of personality traits with mood and somatic symptoms in multiple sclerosis

BACKGROUND

Research suggest that personality traits influence the mood and somatic symptoms in various different clinical populations. Neuroticism, extraversion, conscientiousness, openness to experience, and agreeableness have been identified as potential predictors of mood and somatic symptoms. However, the literature on personality traits and symptom outcomes in multiple sclerosis (MS) is limited, highlighting the necessity for more in-depth research.

OBJECTIVE

This Cross-sectional study aimed to investigate the association between personality traits and symptomatology in individuals with MS using two separate studies and different personality assessment tools- the NEO Five-Factor Inventory (NEO-FFI) and the Ten Item Personality Inventory (TIPI).

METHODS

Participants completed surveys assessing mood and somatic symptoms. Linear regression analyses were performed to examine the associations between personality traits and MS symptoms controlling for demographic variables.

RESULTS

.The analyses were performed on data from 63 individuals with MS for Study 1 (assessing the NEO-FFI) and 1183 individuals with MS for Study 2 (assessing the TIPI), respectively. Neuroticism was consistently associated with more somatic and mood symptoms in both sample (medium to large effect sizes; β = -0.05 to β = 0.60) Extraversion and conscientiousness were associated with fewer symptoms in Study 2.

CONCLUSIONS

This study highlights the importance of considering personality factors in understanding and managing symptoms in MS. However, further research is needed to understand the causal relationships between personality and symptom outcomes in MS.

Beyond the face: An interdisciplinary evaluation of satisfaction with appearance in young people with orofacial clefts

Orofacial clefts are the most common congenital anomaly of the face, and they significantly affect appearance. The combined effects of demographics, psychology, neurophysiology, and cleft characteristics to explain satisfaction with appearance in young people with a cleft have not yet been comprehensively studied in an interdisciplinary manner. We found that interpersonal difficulties, age, and conscientiousness were significant explanatory factors for satisfaction with appearance (tinterpersonal difficulties = -3.022, p = 0.006; tage = -3.563, p = 0.016; tconscientiousness = 4.161, p = 0.003); the model explained 50% of variance in satisfaction with appearance (R2 Adjusted = 0.504, Fvs. constant = 4.05, p = 0.00117). Furthermore, frontal alpha asymmetry was complexly intertwined with other variables, affecting the overall accuracy of the model, but explaining only 10.5% of variance in satisfaction with appearance when used as a factor alone. The results show that an interdisciplinary approach can substantially expand our understanding of the factors influencing self-perception in young people with orofacial clefts.

When High Subjective Social Status Becomes a Burden: A Japan-U.S. Comparison of Biological Health Markers

High subjective social status (SSS) is believed to protect health in the current literature. However, high SSS entails social responsibilities that can be stressful in collectivistic cultural contexts. Here, we tested the hypothesis that those socialized in collectivistic societies (e.g., Japan) recognize their high social status as entailing social duties difficult to ignore even when they are excessive. Using cross-cultural survey data (N = 1,289) and a measure of biological health risk (BHR) by biomarkers of inflammation and cardiovascular malfunction, we found that higher SSS predicted lower BHR for American males. In contrast, higher SSS predicted higher BHR for Japanese males, mediated by the perceived difficulty of disengaging from their current goals. In both cultural groups, females showed no association between SSS and BHR. These findings suggest that social status has differing health implications, depending on the relative salience of privileges and burden-producing responsibilities in different cultural contexts.

Self-rated health (SRH) partially mediates and associations between personality traits and life satisfaction in older adults

It is established that personality traits contribute to life satisfaction but why they are connected are far less understood. This research report tested if self-rated health (SRH) which is one's subjective ratings of their health and has a high predictivity of actual health mediates the associations between the Big Five model of personality and life satisfaction in a cohort (N = 5,845) of older adults from the UK. By using Pearson's correlation analysis and mediation analysis, the current research reported positive correlations between Agreeableness, Openness, Conscientiousness, and Extraversion, SRH, and life satisfaction. However, Neuroticism was negatively correlated with SRH and life satisfaction. The main findings were that SRH partially mediates the associations between all traits in the Big Five and life satisfaction in older adults. This study began novel exploration on if SRH could explain the connections between the Big Five and life satisfaction. Results revealed SRH could partially explain these associations in all traits. These results may offer additional support to recently developed integrated account of life satisfaction, which argues that there are no single determinants of life satisfaction. Rather, life satisfaction is made up by many factors including but not limited to personality and health.

Personality predicts self-rated health: considering age differences

Self-rated health (SRH) refers to the subjective evaluation of one's own health. Big Five personality traits including Neuroticism, Agreeableness, Openness, Conscientiousness, and Extraversion have been consistently found as significant predictors of SRH. In addition, SRH declines with age, and personality traits change with age. Thus, it is reasonable to speculate that age might moderate the associations between personality traits and SRH. The current study analyzed data from 33,256 participants with a mean age of 45.78 years old and 55.92% females. The current study found that age significantly moderates the associations between Agreeableness, Openness, and Conscientiousness and SRH after controlling for demographic covariates. The current study implies that personality traits relate to SRH differently at different ages. Thus, studies regarding the associations between personality traits and SRH must take the interactions between age and personality traits into account.

Purpose in life and 8-year mortality by gender and race/ethnicity among older adults in the U.S

We examined the associations between a sense of purpose and all-cause mortality by gender and race/ethnicity groups. Data were from the Health and Retirement Study, a nationally representative cohort study of U.S. adults aged >50 (n = 13,159). Sense of purpose was self-reported at baseline (2006/2008), and risk of all-cause mortality was assessed over an 8-year follow-up period. We also formally tested for potential effect modification by gender and race/ethnicity. We observed the associations between higher purpose and lower all-cause mortality risk across all gender and race/ethnicity groups. There was modest evidence that the highest level of purpose (versus lowest quartile) was associated with even lower risk of all-cause mortality among women (risk ratio = 0.66, 95% confidence interval: 0.56, 0.77) compared to men (risk ratio = 0.80, 95% confidence interval: 0.69, 0.93; p-value for multiplicative effect modification =0.07). However, we observed no evidence of effect modification by race/ethnicity. Having a higher sense of purpose appears protective against all-cause mortality regardless of gender and race/ethnicity. Purpose, a potentially modifiable factor, might be a health asset across diverse populations.

The Relationship between Conscientiousness and Well-Being among Chinese Undergraduate Students: A Cross-Lagged Study

Chinese culture attaches great importance to the education and cultivation of youth conscientiousness, however in the context of Chinese culture, little is known about the relationship between conscientiousness and mental and physical health. The present study aimed to investigate whether there is a reciprocal relationship between conscientiousness and well-being (subjective and physical well-being) among Chinese undergraduate students. A series of self-reported questionnaires were administered to 365 undergraduate students in 2 waves, separated by 1 year. Cross-lagged regression analyses were applied to examine the reciprocal relationships. Results indicated that conscientiousness positively predicted subsequent levels of positive affect and life satisfaction, while negatively predicted subsequent levels of negative affect and physical symptoms, controlling for the effects of gender, age, body-mass index, socioeconomic status, and the prior level of conscientiousness. Whereas, positive and negative affect, life satisfaction, and physical symptoms did not significantly predict subsequent levels of conscientiousness. This study suggests that conscientiousness is a robust and prospective predictor of subjective and physical well-being. The reciprocal relationship between conscientiousness and well-being was not confirmed in the current sample of Chinese undergraduate students.

A cultural evolutionary behavior genetics will need a more sophisticated conceptualization of cultural traits

A framework that brings together cultural perspectives and behavior genetics has long been needed. To be successful, however, we need sophistication in the conceptualization of culture. Here, we highlight three imperatives to this end: the need for a clear definition of cultural traits, inclusion of the role of societal power, and recognizing the distinction between traits and characteristic adaptations.

The Stressful Personality: A Meta-Analytical Review of the Relation Between Personality and Stress

The current study presented the first meta-analytic review on the associations between the Big Five personality traits and stress measured under different conceptualizations (stressor exposure, psychological and physiological stress responses) using a total of 1,575 effect sizes drawn from 298 samples. Overall, neuroticism was found to be positively related to stress, whereas extraversion, agreeableness, conscientiousness, and openness were negatively linked to stress. When stress assessed under different conceptualizations was tested, only neuroticism, agreeableness, and conscientiousness were related to stressor exposure. All of the Big Five personality traits were significantly associated with psychological stress perception, whereas the five personality traits showed weak to null associations with physiological stress response. Further moderation analyses suggested that the associations between personality traits and stress under different conceptualizations were also contingent upon different characteristics of stress, sample, study design, and measures. The results supported the important role of personality traits in individual differences in stress.

Your pain, my gain: The relationship between self-report and behavioral measures of everyday sadism and COVID-19 vaccination intention

Vaccination plays a crucial role in containing the spread of the COVID-19 pandemic. However, a significant fraction of the global population is reluctant to take a coronavirus vaccine. A burgeoning literature has considered mainly adaptive personality traits as antecedents of vaccine hesitancy (i.e., Big Five and HEXACO), while maladaptive personality traits (i.e., "Dark Tetrad" of personality) are often a comparatively neglected area. In this research, we examined the relationship between everyday sadism and intention to get vaccinated against COVID-19. We theorized that driven by antisocial tendencies and social indifference, individuals with higher sadism may be less willing to obtain a vaccine. Employing a bug-killing paradigm to capture everyday sadism, we tested this prediction in a Chinese sample of non-student adults (N = 188). Support for this proposition was found in the lab task, which demonstrates that sadism was associated with more vaccine refusal spanning the self-report and behavioral domains. In addition, we showed that the sadistic behavioral choices can be predicted with self-report measure of sadistic personality. These findings highlight the important role of maladaptive personality traits in predicting vaccination attitudes and intentions.

Culture and Health: Recent Developments and Future Directions 1

Evidence of cultural differences in relationships and emotions has accumulated over the past few decades. As findings on cultural differences in psychological processes have accumulated, there has been growing interest in investigating whether they have implications for other phenomena such as health. Using scientific advances from the MIDUS and MIDJA studies, both publicly available, we examine links between culture and health. We first briefly review the accumulated evidence on cultural influences on health correlates of psychosocial factors. We then feature two recent developments - a more micro-level perspective on biological factors that may be involved in the culture and health linkage, and a more macro-level view of socioeconomic inequality, which also matters for health. Both perspectives inform the pathways through which health effects occur. Finally, we conclude our review by highlighting the changing historical contexts surrounding these cross-cultural investigations. Specifically, we draw attention to widening of economic inequality across cultures and the world-wide COVID-19 pandemic. These happenings bring notable implications for future research on health across cultural contexts.

Communion, Care, and Leadership in Computer-Mediated Learning during the Early Stage of COVID-19

This qualitative inquiry explores how, during the early stage of the COVID-19 pandemic in Lithuania (European Union), the stakeholders in the education system—university teachers, general education teachers, students, and children’s parents—coped with the encountered challenge and what was important to them under the changed conditions. This paper uses a communication management objective to describe how participants in the education system responded to the emerging distance learning situation and its challenges. The phenomenographic research approach was chosen to carry out the qualitative study. The 37 interviews from higher education teachers, university students, school teachers, and parents of minor school-aged children were conducted during the early stage of COVID-19 quarantine. The research allows for concluding that, after a successful transition to distance learning, the dimensions of communion and supportive collaboration acquired importance among stakeholders in education. Starting new activities, a need for communion and mobilization for joint activities under the crisis emerged. The research showed that the adaptation period was necessary at the beginning of these new activities. Competent leadership was expected from the teacher. Additionally, the preparation of all the actors in the education process was needed. The data offer a window into the dynamics of online teaching in crisis and experiences with a new activity that are key to success. Although research on technology-mediated learning has increased in recent years, it still lags behind developments in practice.
