Observational Study
OBJECTIVES
Clinical observations and studies of retrospective observer ratings point to changes in personality in persons with cognitive impairment or dementia. The timing and magnitude of such changes, however, are unclear. This study used prospective self-reported data to examine the trajectories of personality traits before and during cognitive impairment.
DESIGN
Longitudinal observational cohort study.
SETTING AND PARTICIPANTS
Older adults from the United States in the Health and Retirement Study were assessed for cognitive impairment and completed a measure of the 5 major personality traits every 4 years from 2006 to 2020 (N = 22,611; n = 5507 with cognitive impairment; 50,786 personality and cognitive assessments).
METHODS
Multilevel modeling examined changes before and during cognitive impairment, accounting for demographic differences and normative age-related trajectories.
RESULTS
Before cognitive impairment was detected, extraversion (b = -0.10, SE = 0.02), agreeableness (b = -0.11, SE = 0.02), and conscientiousness (b = -0.12, SE = 0.02) decreased slightly; there was no significant change in neuroticism (b = 0.04, SE = 0.02) or openness (b = -0.06, SE = 0.02). During cognitive impairment, faster rates of change were found for all 5 personality traits: neuroticism (b = 0.10, SE = 0.03) increased, and extraversion (b = -0.14, SE = 0.03), openness (b = -0.15, SE = 0.03), agreeableness (b = -0.35, SE = 0.03), and conscientiousness (b = -0.34, SE = 0.03) declined.
CONCLUSIONS AND IMPLICATIONS
Cognitive impairment is associated with a pattern of detrimental personality changes across the preclinical and clinical stages. Compared with the steeper rate of change during cognitive impairment, the changes were small and inconsistent before impairment, making them unlikely to be useful predictors of incident dementia. The study findings further indicate that individuals can update their personality ratings during the early stages of cognitive impairment, providing valuable information in clinical settings. The results also suggest an acceleration of personality change with the progression to dementia, which may lead to behavioral, emotional, and other psychological symptoms commonly observed in people with cognitive impairment and dementia.

Using data from the Survey of Health, Ageing and Retirement in Europe, we regressed three well-being measures (CASP, life satisfaction and Euro-D depressive symptoms) on indicators of personality and social network. Personality was indicated by the Big-Five personality traits, while social network was measured in terms of size, contact frequency and emotional closeness. The analysis also considered personality-network interactions, controlling for confounders. The sample was comprised of 35,145 adults, aged 50 and older, from 24 European countries and Israel The results revealed that the personality traits explained more variance in the well-being outcomes than the social network characteristics did. However, the interactions showed that the social network characteristics, particularly size and mean emotional closeness, offset the effects of dysfunctional personality attributes on subjective well-being in late life. Hence, social network characteristics were shown to modify the potentially ill effects of personality on key well-being indicators.

This study explores the relationship between bright- and dark-side personality traits and four major styles of defense mechanisms (DMs) as this relationship remains unexplored and important in understanding the DMs. In all, 435 adult working participants (241 men; 194 women; Mean age 46.06 yrs) mainly in middle management jobs, completed a 78-item, six-trait measure of bright-side personality (HPTI: High Potential Type Indicator), a 25-item five-trait measure of the dark-side personality (PID-5;BF: DSM-5-Brief Form) and 88-item, four-styles measure of defense mechanisms (Defense Style Questionnaire). The aim was to examine demographic (sex, age, education), ideological and personality trait correlates of the DMs. It was hypothesized that the dark-side traits, particularly Detachment would be most strongly related to the DMs. Thereafter, a hierarchical linear regression was performed with each DM factor as criterion and predictors being demography, ideology, self-esteem as well as bright- and dark-side personality traits. Detachment was associated with all DMs, particularly Maladaptive (r = 0.68) and Image Distorting Style (r = 0.38) while Conscientiousness was associated with none. One implication concerns the assessment of DMs by standard tests. Limitations are acknowledged and include method invariance and sample homogeneity.

This study explored demographic, ideological, self-rating and personality traits correlates of the Dark Tetrad (DT4) which measures Narcissism (Special), Machiavellianism (Crafty), Psychopathy (Wild), and Sadism (Mean) traits. In total, 447 adults completed three tests: a bright-side, work-related, personality test (HPTI: High Performance Type Indicator), a dark-side test (Short Dark Tetrad) and a number of self-ratings. Correlations and regressions showed that all four dark traits were associated with low Adjustment (Neuroticism), but also with high Risk-Taking and Competitiveness (low Agreeableness). The various measures accounted for a third of the variance in explaining the Mean (Sadistic) score, and 40 % for Special (Narcissism). Trait Competitiveness was most closely associated with all four dark traits.

OBJECTIVE
The aim of the current study is to investigate the associations between personality traits and mental health in people with asthma and compare it with people without asthma.
METHODS
Data came from UKHLS with 3929 patients with asthma with a mean age of 49.19 (S.D. = 15.23) years old (40.09 % males) and 22,889 healthy controls (42.90 % males) with a mean age of 45.60 (S.D. = 17.23) years old. First, the current study investigated the difference in Big Five personality traits and mental health between people with and without asthma using a predictive normative modeling approach with one-sample t-tests. Second, a hierarchical regression accompanied by two multiple regressions was used to determine how personality traits may relate to people with and without asthma differently.
RESULTS
The current study found asthma patients have significantly higher Neuroticism, higher Openness, lower Conscientiousness, higher Extraversion, and worse mental health. Asthma status significantly moderated the association between Neuroticism and mental health with this relationship being stronger in people with asthma. Moreover, Neuroticism was positively related to worse mental health and Conscientiousness and Extraversion were negatively associated with worse mental health in people with and without asthma. However, Openness was negatively associated with worse mental health in people without asthma but not in people with asthma.
LIMITATIONS
The limitations of the current study include cross-sectional designs, self-reported measured, and limited generalizability to other countries.
CONCLUSION
Clinicians and health professionals should use findings from the current study to come up with prevention and interaction programs that promote mental health based on personality traits in asthma patients.

Review
Despite the historically consolidated psychopathological perspective, on the one hand, contemporary organicistic psychiatry often highlights abnormalities in neurotransmitter systems like dysregulation of dopamine transmission, neural circuitry, and genetic factors as key contributors to schizophrenia. Neuroscience, on the other, has so far almost entirely neglected the first-person experiential dimension of this syndrome, mainly focusing on high-order cognitive functions, such as executive function, working memory, theory of mind, and the like. An alternative view posits that schizophrenia is a self-disorder characterized by anomalous self-experience and awareness. This view may not only shed new light on the psychopathological features of psychosis but also inspire empirical research targeting the bodily and neurobiological changes underpinning this disorder. Cognitive neuroscience can today address classic topics of phenomenological psychopathology by adding a new level of description, finally enabling the correlation between the first-person experiential aspects of psychiatric diseases and their neurobiological roots. Recent empirical evidence on the neurobiological basis of a minimal notion of the self, the bodily self, is presented. The relationship between the body, its motor potentialities and the notion of minimal self is illustrated. Evidence on the neural mechanisms underpinning the bodily self, its plasticity, and the blurring of self-other distinction in schizophrenic patients is introduced and discussed. It is concluded that brain-body function anomalies of multisensory integration, differential processing of self- and other-related bodily information mediating self-experience, might be at the basis of the disruption of the self disorders characterizing schizophrenia.

Emotional well-being has a known relationship with a person's direct social ties, including friendships; but do ambient social and emotional features of the local community also play a role? This work takes advantage of university students' assignment to different local networks-or "social microclimates"-to probe this question. Using Least Absolute Shrinkage and Selection Operator (LASSO) regression, we quantify the collective impact of individual, social network, and microclimate factors on the emotional well-being of a cohort of first-year college students. Results indicate that well-being tracks individual factors but also myriad social and microclimate factors, reflecting one's peers and social surroundings. Students who belonged to emotionally stable and tight-knit microclimates (i.e., had emotionally stable friends or resided in densely connected residence halls) reported lower levels of psychological distress and higher levels of life satisfaction, even when controlling for factors such as personality and social network size. Although rarely discussed or acknowledged in the policies that create them, social microclimates are consequential to well-being, especially during life transitions. The effects of microclimate factors are small relative to some individual factors; however, they explain unique variance in well-being that is not directly captured by emotional stability or other individual factors. These findings are novel, but preliminary, and should be replicated in new samples and contexts. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

This study explored impacts of the COVID-19 pandemic on creativity and productivity and how personality variables moderated these impacts. Two online self-report surveys were conducted. 863 (spring 2020) and 421 (spring 2021) participants were asked how the corona crisis affected their creativity and productivity. In addition, personality variables, namely the Big Five (openness, conscientiousness, extraversion, agreeableness, neuroticism), as well as interpersonal trust, need for cognition, risk-taking, and life satisfaction, were assessed. As a result of the crisis, the group of participants appeared more creative in 2020, while no significant group effect of the pandemic was found for productivity. In 2021, however, the crisis had a negative impact on creativity and productivity. In 2020, predictors for an improved creativity were openness, conscientiousness, neuroticism, and life satisfaction; predictors for improved productivity were conscientiousness, negative interpersonal trust, and life satisfaction. In 2021, only life satisfaction predicted improved creativity, while improved productivity was predicted by conscientiousness, negative neuroticism, and life satisfaction. At its beginning, the COVID-19 pandemic had, on average, a positive effect on creativity and a neutral one on productivity. Later, the impact turned negative on both creativity and productivity. Here, lower life satisfaction was particularly relevant.

INTRODUCTION
Previous research has shown that personality traits and gaming motives are important predictors for explaining regular and disordered gaming. However, the mediating role of gaming motives in the relation between personality traits and video game outcomes (e.g., time spent gaming or disordered gaming) has been scarcely studied and limited cross-national studies have addressed this issue. The present study aimed to examine the direct and indirect effects of the Big Five personality traits on weekly gaming and disordered gaming via gaming motives across seven countries.
METHOD
3540 college student gamers (59.5% women) from the U.S., Canada, Spain, Argentina, Uruguay, South Africa and England completed the online survey. Structural equation modeling was conducted to test models. Multigroup models were employed to test model invariance across countries.
RESULTS
Significant, albeit weak, relations were found between personality traits and gaming outcomes, and were mediated mostly by coping motives in predicting disordered gaming, and by social interaction and recreation (to a lesser extent) motives in predicting weekly gaming. Some minor, yet significant, differences across countries appeared and are discussed in detail.
DISCUSSION
The present findings indicate that the differential interrelations between personality traits, gaming motives, and video gaming outcomes may be generalized in college students across countries.

Review
We give an overview of what age stereotypes (AS) are, how they are acquired and change across the lifespan, and how they shape development in old age. AS reflect complex beliefs and expectations that vary on the following dimensions: They differ in content and valence, depending on the life-domain to which they are applied (context), they refer to different age-groups (reference), to older people or to oneself as an old person (direction of relevance), and they either describe how older people are or prescribe how they should be (modality). AS are acquired early, and later taint beliefs about one's own aging (internalization). Once they are part of the self-concept, AS act as self-fulfilling prophecies that shape the actual aging process (stereotype embodiment).
