Concurrent and longitudinal relations among conscientiousness, stress, and self-perceived physical health

Extraordinary nature and human recovery: Psychological and physiological perspectives

The restorative effect of natural environments on human well-being has garnered significant attention in psychology and environmental science. However, extraordinary nature-such as volcanoes, glaciers, and starry skies-has been largely underexplored despite its potential to elicit stronger emotional and physiological responses. Similarly, personality analysis has been somewhat overlooked in environmental psychology research. This study investigates the psychophysiological benefits of both extraordinary and ordinary natural environments, focusing on emotional recovery, cognitive focus, and physiological relaxation. We incorporate personality traits, gender, and awe as key factors in understanding recovery outcomes. Using a sample of 88 young adults(44males, 44females) with 20.2 (SD = 1.1)average year old, we evaluated psychological and physiological recovery indicators, including alpha and beta wave activity measured by EEG, as well as derived indices of focus and relaxation from EEG data, and self-reported psychological recovery.The results indicate that: (1) Extraordinary nature leads to significantly greater restorative effects on psychological and physiological outcomes, with marked improvements in alpha and beta waves, focus, relaxation, and psychological recovery scores. (2) Not all individuals favor extraordinary nature; two-way ANOVA reveals that individuals with high openness and extraversion show a stronger preference for extraordinary nature. (3) A higher sense of awe towards nature correlates strongly with better recovery outcomes, as demonstrated through correlation analysis and fitting curves. (4) Gender differences reveal that men tend to prefer extraordinary nature, with stronger recovery outcomes. This study introduces new perspectives into green space planning, urban landscape design, and environmental psychology, emphasizing the importance of incorporating stunning elements into public spaces to promote psychological and physical health, accelerate the achievement of the 17 Sustainable Development Goals set by the United Nations, build sustainable cities and communities, responsible consumption and production, land-based living, and promote health and well-being. The research findings indicate that extraordinary nature can be a powerful tool for improving public health and provide valuable insights for creating more sustainable and restorative urban environments.

Testing of significant changes in big-five personality factors over time in the presence and absence of memory impairment and life-related stress

This study tests whether memory impairment and perceived increases in stress due to life changes independently contribute to similar personality changes, such as increased neuroticism and decreased conscientiousness. Longitudinal data from 12,912 participants aged 50+ from the Health and Retirement Study (2006-2020) were analyzed using Latent Growth Curve Models (LGCMs). Six LGCMs were simultaneously estimated to examine how changes in personality across three data points spanning 8 years are predicted by both the classification of memory impairment (MI) statuses assessed via the Telephone Interview for Cognitive Status and estimated increases in life stress. Decreases were observed in all Big Five personality factors (B =  - 0.240/- 0.510, SE = 0.085/0.089) over the 8-year period. No significant differences in personality changes were found between MI cases and non-MI cases. Increased life stress was significantly associated with a rise in neuroticism (B = 0.587, SE = 0.094) and reductions in conscientiousness, extraversion, agreeableness, and openness (B ranges from - 0.223 to - 0.497). The findings emphasize adaptive/developmental shifts in personality in response to life stress rather than neuropathological ones related to memory impairment. Clinical assessment of personality changes in mid-to-late life should first consider psychological maladaptation to situational threats and challenges.

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.

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.

Big Five traits predict stress and loneliness during the COVID-19 pandemic: Evidence for the role of neuroticism

The rapid outbreak of the coronavirus disease (COVID-19) has affected citizens' daily lives in an unprecedented way. To curb the spread of the pandemic, governments have taken numerous measures such as social distancing and quarantine, which may be associated with psychological consequences, namely stress and loneliness globally. To understand differential associations of personality traits with psychological consequences of COVID-19, we utilize data from a sample of 99,217 individuals from 41 countries collected as part of the COVIDiSTRESS Global Survey. Data were analyzed using multigroup confirmatory factor analysis and multilevel regression models. Findings showed that while some of the associations were rather weak, Big Five personality traits were significantly associated with perceived stress and loneliness during the pandemic. Our study illustrates that neuroticism especially can be a vulnerability factor for stress and loneliness in times of crisis and can contribute to detection of at-risk individuals and optimization of psychological treatments during or after the COVID-19 pandemic.

Dispositional mindfulness mediates the relationship between conscientiousness and mental health-related issues in adolescents during the COVID-19 pandemic

The COVID-19 pandemic is seriously affecting the mental health of adolescents and triggering a series of mental health-related issues. The present study investigates the relationships between conscientiousness, dispositional mindfulness (DM), and adolescents' mental health-related issues including anxiety, depression, and perceived stress during this time. In this study, after obtaining informed consent from participants' parents, 5994 Chinese adolescents voluntarily and anonymously completed an online survey. Conscientiousness was found to be negatively associated with anxiety, depression, and perceived stress. It was found to be positively associated with DM, which, in turn, negatively predicts anxiety, depression, and perceived stress. Conscientiousness is thus related to mental health-related issues, and this relationship is mediated by DM. This mediation effect is stronger in females than in males. These findings provide new and strong evidence for the protective role of conscientiousness and DM in adolescents' mental health-related issues during the COVID-19 pandemic.

Personality and responses to Covid-19 health and safety prevention

In this study, we examine the respective effects of prosocial personality and grandiose narcissism on individual social responsibility, and attitudinal and behavioral responses to Covid-19 health and safety preventive measures. We further analyze the extent to which individuals feel targeted by bullies for wearing a mask in order to shed light on the psychological consequences of the current pandemic. We employed a cross-sectional technique using a snowball sampling method to recruit participants from the United States and Canada. We obtained a total of 968 completed surveys. Results of SEM reveal that prosocial personality enhances individual social responsibility and positive responses to health and safety preventive measures, whereas grandiose narcissism augments negative responses. Results highlight that socially responsible individuals report being bullied for wearing a mask. Findings are discussed in light of the characteristics of the respondents, and cultural aspects.

The Roles of General and Domain-Specific Perceived Stress in Healthy Aging

OBJECTIVES

Theoretical and empirical evidence suggests the existence of a general perceived stress factor overarching different life domains. The present study investigated the general perceived stress relative to domain-specific perceived stress as predictors of 26 diverse health outcomes, including mental and physical health, health behaviors, cognitive functioning, and physiological indicators of health.

METHOD

A bifactor exploratory structural equational modelling (BiESEM) approach was adopted in two aging samples from the Health and Retirement Study (HRS; N = 8325 in Sample 1, N = 7408 in Sample 2).

RESULTS

Across the two samples, perceived stress was well-represented by a bifactor structure where there was a robust general perceived stress factor representing a general propensity towards stress perception. Meanwhile, after controlling for the general perceived stress factor, specific factors that represent perceived stress in different life domains were still clearly present. Results also suggested age, sex, race, education, personality traits, and past and recent stressor exposure as possible factors underlying individual differences in the general perceived stress factor. The general perceived stress factor was the most robust predictor of the majority of health outcomes, as well as changes in mental health outcomes. The specific factor of perceived neighborhood stress demonstrated incremental predictive effects across different types of health outcomes.

DISCUSSION

The current study provides strong evidence for the existence of a general perceived stress factor that captures variance shared among stress across life domains, and the general perceived stress factor demonstrated substantial prospective predictive effects on diverse health outcomes in older adulthood.

Conscientiousness and perceived physical symptoms: Mediating effect of life events stress and moderating role of resting respiratory sinus arrhythmia

This study investigated the possible psychophysiological links between conscientiousness and perceived physical symptoms by examining the mediating role of life events stress and the moderating role of resting respiratory sinus arrhythmia (RSA). Participants participated in the collection of questionnaire data and physiological data (N = 396). Results showed life events stress mediated the association between conscientiousness and perceived physical symptoms, and the indirect effect was only significant among individuals with lower resting RSA. Findings indicate that low resting RSA as a risk-amplifying physiological marker may magnify the relationship that low conscientiousness affects physical symptoms by increasing life events stress.

Associations of chronotype, Big Five, and emotional competences with perceived stress in university students

This study aimed to investigate the associations between individual difference factors (chronotype, Big Five, emotional competences) and perceived stress in French university students. In total, 362 students agreed to take part (M _age = 20.19 ± 1.75 years). Participants completed the Caen Chronotype Questionnaire, Big Five Inventory, the Profile of Emotional Competences, and the Perceived Stress Scale. Results showed that chronotype amplitude (+), eveningness chronotype (+), neuroticism (+), conscientiousness (-), and intrapersonal emotional competences (-) were important for perceived stress. These findings have theoretical and practical implications in terms of identifying students who might benefit most from stress management interventions.

Becoming More Conscientious or More Open to Experience? Effects of a Two–Week Smartphone–Based Intervention for Personality Change

Research indicates that it might be possible to change personality traits through intervention, but this clinical research has primarily focused on changing neuroticism. To date, there are no established, proven techniques for changing other domains of personality, such as conscientiousness and openness. This research examined the effects of a two–week smartphone–based intervention to either change one facet of conscientiousness (i.e. self–discipline) or one facet of openness to experience (i.e. openness to action). Two intervention studies (total N = 255) with two active intervention groups for mutual comparisons were conducted. Results of self–reports and observer reports showed that people who wanted to become more self–disciplined were less self–disciplined at pretest. Similarly, people who wanted to become more open to action were less open to action at pretest. The results showed that people who chose the self–discipline intervention showed greater increases in self–discipline, and people who chose the openness to action intervention showed greater increases in openness to action compared with the other group. Changes were maintained until follow–up two and six weeks after the end of the intervention. Future work is needed to examine whether these personality changes are enduring or reflect temporary accentuation as a result of participation in the intervention. © 2020 European Association of Personality Psychology

The Relationship between Self-Esteem and Depression when Controlling for Neuroticism

Much research has examined the interplay of depression and self-esteem in an effort to determine whether depression causes self-esteem (scar model), or vice versa (vulnerability model). In the current longitudinal study (N = 2,318), we tested whether neuroticism served as a confounding variable that accounted for the association of depression and self-esteem, using both cross-lag models and latent growth models. We found neuroticism accounted for the majority of covariance between depression and self-esteem, to the degree that the scar and vulnerability models appear to be inadequate explanations for the relation between depression and self-esteem. Alternatively, neuroticism appears to be a viable cause of both depression and self-esteem and could explain prior work linking the two constructs over time.

Polygenic Score for Alzheimer Disease and cognition: The mediating role of personality

Alzheimer's disease (AD) polygenic risk score (PGS) is associated with lower cognitive functioning even among older individuals without dementia. We tested the hypothesis that personality traits mediate the association between AD genetic risk and cognitive functioning. Participants (N > 7,000, aged 50-99 years old) from the Health and Retirement Study were genotyped and completed personality and cognition tests at baseline. Cognition was assessed again four years later. Bootstrap analysis revealed that a higher AD polygenic risk score was associated with lower cognitive scores at baseline through higher neuroticism, lower conscientiousness, and lower levels of the industriousness facet of conscientiousness. In addition, a higher polygenic score for AD was associated with decline in cognition over four years in part through higher neuroticism and lower conscientiousness. The findings support the hypothesis that the genetic vulnerability for AD contributes to cognitive functioning in part through its association with personality traits.

School or Work? The Choice May Change Your Personality

According to the social-investment principle, entering new environments is associated with new social roles that influence people’s behaviors. In this study, we examined whether young adults’ personality development is differentially related to their choice of either an academic or a vocational pathway (i.e., entering an academic-track school or beginning vocational training). The personality constructs of interest were Big Five personality traits and vocational-interest orientations. We used a longitudinal study design and propensity-score matching to create comparable groups before they entered one of the pathways and then tested the differences between these groups 6 years later. We expected the vocational pathway to reinforce more mature behavior and curtail investigative interest. Results indicated that choosing the vocational compared with the academic pathway was associated with higher conscientiousness and less interest in investigative, social, and enterprising activities.

Big Five personality and health in adults with and without cancer

Personality is associated with health, but examinations in patients with illnesses are lacking. We aimed to determine whether personality-physical health associations differed between community and cancer samples. This cross-sectional study involved 168 participants without cancer, 212 men with prostate cancer, and 55 women with breast cancer. We examined whether the Big Five personality dimensions were associated with health behaviors and multiple health indicators. Higher conscientiousness and lower neuroticism were associated with better health behaviors and health (r_max = .31), with few differences between community and cancer samples. Findings call for research on the implications of personality in patients with serious illnesses.

Examining conscientiousness as a key resource in resisting email interruptions: Implications for volatile resources and goal achievement

Within the context of the conservation of resources model, when a resource is deployed, it is depleted – albeit temporarily. However, when a ‘key’, stable resource, such as Conscientiousness, is activated (e.g., using a self‐control strategy, such as resisting an email interruption), we predicted that (1) another, more volatile resource (affective well‐being) would be impacted and that (2) this strategy would be deployed as a trade‐off, allowing one to satisfy task goals, at the expense of well‐being goals. We conducted an experience‐sampling field study with 52 email‐users dealing with their normal email as it interrupted them over the course of a half‐day period. This amounted to a total of 376 email reported across the sample. Results were analysed using random coefficient hierarchical linear modelling and included cross‐level interactions for Conscientiousness with strategy and well‐being. Our first prediction was supported – deploying the stable, key resource of Conscientiousness depletes the volatile, fluctuating resource of affective well‐being. However, our second prediction was not fully realized. Although resisting or avoiding an email interruption was perceived to hinder well‐being goal achievement by Conscientious people, it had neither a positive nor negative impact on task goal achievement. Implications for theory and practice are discussed.

Practitioner points

It may be necessary for highly Conscientious people to turn off their email interruption alerts at work, in order to avoid the strain that results from an activation‐resistance mechanism afforded by the arrival of a new email.

Deploying key resources means that volatile resources may be differentially spent, depending on one's natural tendencies and how these interact with the work task and context. This suggests that the relationship between demands and resources is not always direct and predictable.

Practitioners may wish to appraise the strategies they use to deal with demands such as email at work, to identify if these strategies are assisting with task or well‐being goal achievement, or whether they have become defunct through automation.

Interactive Effects of Trait Self-Control and Stress Appraisals on Blood Pressure Responses to a Laboratory Stressor

Purpose

Stress may play a role in explaining part of the conscientiousness-longevity relationship. Conscientiousness (C) is associated with the appraisals of stressors and its lower-order facets have been shown to differentially moderate the experience of stress in daily life. This study investigated whether the lower-order facet, self-control (SC), moderated the relationship between stress appraisals and blood pressure responses to a laboratory stressor.

Methods

Ninety participants (selected from the upper and lower quartiles for C scores from a sample of 679 participants) were invited to complete the Maastricht Acute Stress Test (MAST). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were assessed throughout the stress task. Stress appraisals were assessed at baseline.

Results

Blood pressure responses to the MAST were similar in participants who scored high and low in SC. However, primary appraisals were negatively associated with BP reactivity and recovery in the high SC group but not in the low SC group. Moreover, SC was found to moderate the relationship between primary appraisals and SBP and DBP reactivity values, such that higher primary appraisals were associated with lower BP reactivity in individuals high in SC but not in those low in SC. In addition, lower SBP recovery values were observed in the high SC group compared to their low SC counterparts.

Conclusions

These findings indicate that SC may influence health status by modifying the relationship between perceived demands and blood pressure. Moreover, having a greater stake in stressors may yield health benefits in the longer term for individuals high in SC.

Toward a Shared Understanding of Important Consequences of Personality

The assumption that personality makes a difference in people's everyday lives is probably the main reason why investigating personality seems worthwhile at all. Although the number of empirical studies addressing the everyday consequences of personality is considerable, an overarching conceptual framework is missing. We present such a framework, using a version of the SORKC model from cognitive-behavioral therapy. Our version of the model incorporates a full account of how personality may influence the ways in which people perceive and respond to situations, which may ultimately have important consequences for them and others. However, not everything that formally qualifies as a consequence of personality is equally relevant. In choosing criterion variables for their own research, researchers interested in personality consequences seem to have strongly relied on implicit assumptions regarding a “good life.” We review a sample of recent studies from the personality literature, using our own conceptualization of important personality consequences to assess the current state of the field, and deduce recommendations for future research.

Generality or Specificity? Examining the Relation between Personality Traits and Mental Health Outcomes Using a Bivariate Bi–factor Latent Change Model

Most previous research has focused on the relationships between specific personality traits and specific facets of mental health. However, in reality most of the Big Five are associated at non–trivial levels with mental health. To account for this broad correlation, we proposed the ‘barometer hypothesis’, positing that behind both ratings of mental health and personality lies a barometer that indicates one's general feelings of positivity or negativity. To the extent that both the general factors of personality and mental health reflect this same barometer, we would expect them to be correlated. We tested alternative models using data from a large longitudinal panel study that includes two cohorts of participants who were assessed every two years, resulting in parallel 4–year longitudinal studies. Similar results were obtained across both studies. Supporting the ‘barometer hypothesis’, findings revealed that the optimal model included general latent factors for both personality traits and mental health. Compared to the broad raw pairwise correlations, the bi–factor latent change models revealed that the relation among levels and changes in the specific factors were substantially reduced when controlling for the general factors. Still, some relations remained relatively unaffected by the inclusion of the general factor. We discuss implications of these findings. Copyright © 2016 European Association of Personality Psychology
