Brief report: How short is too short? An ultra-brief measure of the big-five personality domains implicates "agreeableness" as a risk for all-cause mortality

Associations Between a General Factor and Group Factor from the Spanish-Language Eysenck Personality Questionnaire-Revised Short Form's Neuroticism Scale and the Revised NEO Personality Inventory Domains and Facets

Prior studies used exploratory bifactor analyses to examine the structure of the Neuroticism scale from the Short-scale Eysenck Personality Questionnaire-Revised (EPQ-RS). These studies revealed a general factor and two group factors-Anxious-Tense and Worried-Vulnerable. These factors were related to poorer mental health, but their associations with physical health differed, as did their genetic and neurobiological underpinnings. A later study found that their associations with the Big Five Inventory-2 Short Form's factors and facets differed. We reanalyzed data on 1,006 Spanish students who completed Spanish-language versions of the EPQ-RS and the Revised NEO Personality Inventory (NEO PI-R). Using confirmatory factor analysis, we showed that a model comprising the general factor and a group factor-Anxious-Tense-fit well. In later correlations, a joint factor analysis, and simultaneous multiple regressions, we showed that the EPQ-RS's general factor and the group factor had different patterns of associations with the NEO PI-R domains and facets. These associations were consistent with the definition of the EPQ-RS Neuroticism scale's general factor and that of the group factor. Further investigation into the EPQ-RS Neuroticism scale's structure can improve our understanding of neuroticism's relationship with health and other outcomes.

Measuring the Four Higher-Order Values in Schwartz's Theory: Validation of a 17-Item Inventory

Schwartz's theory of basic human values is the dominant framework for assessing values. One of its strengths is that it allows for different levels of analysis. The 10 basic values can be reliably assigned to four higher-order dimensions: Openness to Change, Conservation, Self-Transcendence, and Self-Enhancement. In this paper, we examined the psychometric properties of the Higher-Order-Value Scale-17 (HOVS17), an inventory that economically assesses these higher-order values. We analyzed data from the GESIS Panel, an ongoing large-scale probability-based panel study that fields HOVS17 annually since 2013 and for which HOVS17 was originally developed. We found HOVS17 to have satisfactory psychometric properties. The 17 items were located in the two-dimensional multi-dimensional scaling (MDS) space as hypothesized. All four subscales were unidimensional, showed good fit when modeled as reflective latent variables, and had acceptable reliabilities as well as one-year test-retest stabilities (.65 to .69). The subscales correlated in theoretically plausible ways with a wide range of correlates and criteria, such as personality traits and well-being. This demonstrates that HOVS17 provides a sound basis for studying the development, precursors, and consequences of the higher-order values in the GESIS Panel and in future surveys that adopt HOVS17. We also discuss suggestions for further improvements of the inventory.

Determinants of Depressive Symptoms Among Patients with Rheumatoid Arthritis in China: A Structural Equation Model

Background

This study aimed to examine how personality traits, social support and clinical features including pain, disease activity, functional status, sleep quality, and fatigue influence on depressive symptoms in Chinese rheumatoid arthritis (RA) patients.

Methods

This study was conducted from November, 2022 to June, 2023 among Chinese RA patients. Pain, disease activity, functional status, sleep quality, fatigue, social support, personality traits, and depressive symptoms were assessed. The following relationships among three hypotheses were analyzed by structural equation model (SEM): H1: clinical features have a direct effect on depressive symptoms; H2: personality traits might work as a mediator between clinical features and depression; H3: social support is related to depressive symptoms, being a direct effect or an indirect effect through clinical features or personality traits.

Results

The final model including 326 RA patients presented a good fit (χ2=103, χ2/df=1.69; GFI=0.96; AGFI=0.93; CFI=0.97; TLI=0.96; RMSEA=0.046). Clinical features had a total effect of 0.59 on depressive symptoms, of which β=0.33 (P=0.013) was an indirect effect through personality traits, indicating a mediating influence between this relationship; moreover, there was a significant direct association between clinical features and depressive symptoms (β=0.26; P=0.022). Personality traits (β=-0.65; P<0.001) had a much stronger relation with depressive symptoms than with clinical features. Social support had a total effect of 0.81 on personality traits, being a direct effect of β=0.52 (P<0.001) and an indirect effect of β=0.29 (P<0.001) through clinical features. The final proposed model explained 77% of the variance of depressive symptoms.

Conclusion

Personality traits had a considerable influence upon depressive symptoms, while social support seemed to have a major effect on personality traits. It is necessary to apply comprehensive assessment and interventions of patients' personality traits, clinical features, as well as social support, which could optimize their mental health.

Niche diversity effects on personality measurement - evidence from large national samples during the COVID-19 pandemic

We report systematic variability in the psychometric properties of a brief personality inventory during the early stages of the COVID-19 pandemic. Drawing upon recent discussions about the universality vs cultural relativism of personality measures, we review and comparatively test theories predicting systematic variability in personality measurement across cultures using an established brief personality measure applied to population samples in 16 nations during the first wave of the COVID-19 pandemic (N = 35,052). We found systematic variation in factor replicability and effective dimensionality. In line with previous theorizing, factors replicated better in contexts with greater niche diversity. Examining possible drivers underlying this association, the investigation of the individual components in the niche construction index suggested that life expectancy and to a lesser degree economic complexity are associated with greater personality structure differentiation. Population-level indicators of acute threat due to COVID-19 did not show credible effects. These patterns suggest that a) investigation of personality structure in population samples can provide useful insights into personality dynamics, b) socioecological factors have a systematic impact on survey responses, but c) we also need better theorizing and research about both personality and culture to understand how niche construction dynamics operate.

The impact of personality traits on medication adherence and self-care in patients with type 2 diabetes mellitus: The moderating role of gender and age

OBJECTIVES

This study aimed to investigate the role of the five-factor model of personality (FFM) and the moderating role of gender and age in predicting medication adherence (MA) and self-care behaviors (SCB) among Iranian patients with type 2 diabetes mellitus (T2DM).

METHODS

This study was conducted on 495 patients with T2DM (73.5% female; n = 364) from two major cities of Iran (Tehran and Qom) in 2019. Pearson's correlation coefficient, multiple regression analysis, and conditional process analysis were performed. P < .05 and P < .10 were considered significant for the relationships and moderation analysis, respectively.

RESULTS

Neuroticism indicated a negative association with MA and SCB. Positive associations were found between MA and personality traits, including extraversion, agreeableness, and conscientiousness, whereas extraversion showed a weak correlation with SCB. According to the covariate-adjusted regression model, neuroticism had a negative effect on MA and SCB. Agreeableness had a positive effect on MA and a negative effect on SCB. However, extraversion exerted a negative effect on MA and a positive effect on SCB. Also, the negative effect of neuroticism on MA was highlighted in women, indicating marginally significant moderation effect. The positive effects of extraversion and conscientiousness on MA were moderated by age. The effect of conscientiousness on SCB was positive in young patients and negative in old patients. No interaction effect was observed between age and gender.

CONCLUSION

This study indicated that neuroticism, extraversion, and agreeableness significantly contributed to MA, but not to SCB. However, the effects were conditioned by age for extraversion and conscientiousness to some extent.

Mortality Risk Associated With Personality Facets of the Big Five and Interpersonal Circumplex Across Three Aging Cohorts

OBJECTIVE

To address the common reliance on the global Big Five domains in the personality and longevity literature, the present study examined mortality risk associated with subdimensions of Big Five domains as well as specific traits within the interpersonal circumplex (IPC) model of personality.

METHODS

Data were drawn from three major longitudinal studies of aging that administered the NEO Personality Inventory-Revised, a comprehensive measure of the Big Five, and comprised a total of 4223 participants. Item Response Theory models were used to generate latent trait scores for each of the 30 Big Five facets and eight scales from the IPC. Pooled mortality risk estimates were obtained from demographic-adjusted Cox regression models within each study.

RESULTS

With a high degree of consistency, the vulnerability facet of neuroticism was associated with higher mortality risk and the activity facet of extraversion, with lower risk. None of the openness or agreeableness facets were associated with mortality, although the IPC scales submissiveness and hostile submissiveness were linked with elevated risk. All but one of the facets in the conscientiousness domain were robustly and consistently associated with lower mortality risk.

CONCLUSIONS

Findings indicate that specific facets of neuroticism and extraversion carry greater or lesser mortality risk. Broad composite scales averaging across all facets mask important personality risk factors. In contrast, nearly all facets within the conscientiousness domain confer protection against mortality. Finally, the IPC model may capture more nuanced interpersonal risk factors than the facets of Big Five agreeableness or extraversion. Understanding of the role of personality in longevity requires a more precise approach to conceptualization and measurement than broad, composite constructs usually provide.

The German Ethical Culture Scale (GECS): Development and First Construct Testing

Misconduct in organizations (such as fraud, stealing, deception, and harming others) is not only a matter of some "bad apples" but also related to the organizational context ("bad barrels"), which can facilitate either ethical or unethical behaviors. Given the financial crisis and recurring corporate ethics scandals, policymakers, regulators and organizations are interested in how to change their organizational cultures to enhance ethical behavior and to prevent further disasters. For this purpose, organizations need to better understand what strategies and factors of the organizational environment can affect (un)ethical behavior. However, to assess the corporate ethical culture, solid measures are required. Since there is an urgent need to have a German measure to promote research in German-speaking countries, this research developed and tested the German Ethical Culture Scale (GECS). Drawing on a prominent approach that has received much attention from scholars and practitioners alike, the GECS attempts to integrate the notion of compliance- and integrity-based ethics programs (with its focus on how to steer organizations) with the notion of ethical culture (with its focus on what factors inhibit or foster ethical behavior). Three studies with heterogeneous samples of German and Swiss employees and managers were conducted to develop, test and validate the multidimensional scale (total N > 2000). Overall, the studies provide first evidence of the measure's construct, criteria-related and incremental validity. The paper concludes with a discussion of the strengths and weaknesses of the GECS and implications for future research.

Do Instagram Profiles Accurately Portray Personality? An Investigation Into Idealized Online Self-Presentation

Instagram users are consistently exposed to the presentation of idealized selves. Although studies have examined online self-presentation in general, little attention has been paid to self-presentation in a visual online setting, such as Instagram. The present investigation examined the extent to which Instagram account holders engage in idealized online self-presentation through a mixed-methods approach. Quantitative results (Study 1) showed a difference between how the observers perceived the Instagram account holders' personality and the Instagram account holders' personality self-reports. Qualitative findings (Study 2) revealed four major themes: (1) Selfies as a personality predictor; (2) Faces as a personality predictor; (3) Layout as personality predictor, (4) Misuse of social networks and its consequence for communication. Our results also indicated that the halo effect is integral to the online self-presentational process, suggesting that an aesthetically pleasing Instagram account or account holder will be better received and thought as having particularly positive personality traits.

How Do Test Takers Interact With Simulation-Based Tasks? A Response-Time Perspective

Many traditional educational assessments use multiple-choice items and constructed-response items to measure fundamental skills. Virtual performance assessments, such as game- or simulation-based assessments, are designed recently in the field of educational measurement to measure more integrated skills through the test takers' interactive behaviors within an assessment in a virtual environment. This paper presents a systematic timing study based on data collected from a simulation-based task designed recently at Educational Testing Service. The study is intended to understand the response times in complex simulation-based tasks so as to shed light on possible ways of leveraging response time information in designing, assembling, and scoring of simulation-based tasks. To achieve this objective, a series of five analyses were conducted to first understand the statistical properties of the timing data, and then investigate the relationship between the timing patterns and the test takers' performance on the items/task, demographics, motivation level, personality, and test-taking behaviors through use of different statistical approaches. We found that the five analyses complemented each other and revealed different useful timing aspects of this test-taker sample's behavioral features in the simulation-based task. The findings were also compared with notable existing results in the literature related to timing data.

Economic Attitudes, Social Attitudes and Their Psychological Underpinnings - A Study of the Finnish Political Elite

We investigated the relation between economic and social attitudes and the psychological underpinnings of these attitudes in candidates (N = 9515) in the Finnish 2017 municipal elections. In this politically elite sample, right-wing economic attitudes and social conservatism were positively correlated (r = 0.41), and this correlation was predominantly driven by those on the economic left being socially liberal, and vice versa. In terms of underlying psychological processes, consistent with dual process models of political ideology, the anti-egalitarian aspect of social dominance orientation was more strongly associated with right-wing economic attitudes, and the conventionalism and aggression aspects of right-wing authoritarianism with social conservatism. Our results show that even in a non-United States context in which the masses organize their political attitudes on two independent dimensions, these dimensions are moderately aligned among certain parts of the political elite, and that the political attitudes of the political elite can be traced to underlying psychological motivations. We argue that equality concerns could play a role in explaining why the left-right and liberal-conservative dimensions are more strongly aligned among those on the left and those more liberal.

Mindfulness - The Missing Link in the Relationship Between Leader-Follower Strategic Optimism (Mis)match and Work Engagement

Assuming a followership perspective and building on implicit leadership theory, this study examines the mediating role of followers' mindfulness in the relationship between leader-follower strategic optimism (mis)match and work engagement. Specifically, we propose that a discrepancy between the respective levels of leaders' and followers' strategic optimism correlates with low levels of mindfulness and work engagement. A field study of 291 working professionals, using polynomial regression and response surface analysis, supports the (mis)match hypotheses. The results demonstrate that followers' mindfulness mediates the relationship between leaders' and followers' matching levels of strategic optimism (whether at high-high and low-low leader-follower strategic optimism conditions) and work engagement. These findings have important implications for training and the extent to which interventions based on personal resources, such as strategic optimism and therefore mindfulness, foster higher work engagement.

An Investigation Into the Relationship Between Onset Age of Musical Lessons and Levels of Sociability in Childhood

Previous studies have suggested that musical training in childhood is beneficial for sociability. However, it remains unclear how age of onset of group music lessons is associated with the late sociability of children from a long-term perspective. This study investigated associations between group music lessons conducted at a music school and children's levels of sociability by focusing on the age of onset of the lessons. We conducted a survey of 276 children aged 4-5 years (M = 58.5 months) and 6-7 years (M = 82.7 months) who commenced music lessons at ages 1, 2, 4, and 6 years. We found that (1) the empathy scores of children aged 6-7 years who began lessons when 1-year-old were greater than those who began lessons when 4-years-old, (2) the communication scores of children aged 4-5 years who began lessons when 1-year-old were greater than those who began lessons when older than 1 year, and (3) the empathy and extraversion scores were high in those aged 6-7 years who began lessons in that age range. The results suggest that early onset of music lessons could positively influence children's sociability; in contrast, after about age 7 years, children who already had high sociability may be more inclined to select group music lessons. By focusing on the impact of regular group music lessons from a very young age on later levels of sociability, these results further elucidate the effects of musical lessons. In sum, participation in group music lessons 2-4 times per month can be effective social training for very young children and foster their later sociability.

Do Individual Differences Influence Moment-by-Moment Reports of Emotion Perceived in Music and Speech Prosody?

Comparison of emotion perception in music and prosody has the potential to contribute to an understanding of their speculated shared evolutionary origin. Previous research suggests shared sensitivity to and processing of music and speech, but less is known about how emotion perception in the auditory domain might be influenced by individual differences. Personality, emotional intelligence, gender, musical training and age exert some influence on discrete, summative judgments of perceived emotion in music and speech stimuli. However, music and speech are temporal phenomena, and little is known about whether individual differences influence moment-by-moment perception of emotion in these domains. A behavioral study collected two main types of data: continuous ratings of perceived emotion while listening to extracts of music and speech, using a computer interface which modeled emotion on two dimensions (arousal and valence), and demographic information including measures of personality (TIPI) and emotional intelligence (TEIQue-SF). Functional analysis of variance on the time series data revealed a small number of statistically significant differences associated with Emotional Stability, Agreeableness, musical training and age. The results indicate that individual differences exert limited influence on continuous judgments of dynamic, naturalistic expressions. We suggest that this reflects a reliance on acoustic cues to emotion in moment-by-moment judgments of perceived emotions and is further evidence of the shared sensitivity to and processing of music and speech.

Differences in Parental Burnout: Influence of Demographic Factors and Personality of Parents and Children

Parental burnout is a syndrome related to parenthood and characterized by three dimensions: emotional and physical exhaustion, emotional distancing of parents from their children, and loss of parental accomplishment. Many factors can explain the interindividual differences in parental burnout (Roskam et al., 2017). In a study conducted among 372 French parents, we examined the relationship between parental burnout, demographic factors (age of parent and child(ren), age of parent at first birth, total number of children, and number of children present in the family home) and parent-assessed dispositional factors (personality traits of parent and child(ren)). Results for demographic factors showed that the younger the parents we surveyed, the higher their reported sense of parental accomplishment, although they also tended to feel more exhausted. We observed a similar pattern of results when we looked at the children's ages. In addition, the number of children at home slightly increased the emotional distance between parent and child(ren). Results for the parents' dispositional factors showed that all three personality traits we investigated, as well as their different facets (lack of emotional control and lack of impulse control for neuroticism, meticulousness and perseverance for conscientiousness, and cooperation and friendliness for agreeableness), were related to parental burnout and its three dimensions. More specifically, parental meticulousness and lack of emotional control were both risk factors for developing parental burnout. By contrast, agreeableness and perseverance were protective factors. With regard to the children, the same three personality traits were linked to the three dimensions of parental burnout. Having children they perceived as having a high level of neuroticism reduced parents' sense of parental accomplishment and increased their emotional exhaustion and distancing. The opposite relationships were found for agreeableness and conscientiousness. There were no significant relationships between parental assessments of their children' extraversion and openness and parental burnout and its three dimensions. The parent's personality explained 42.3% of the variance in parental burnout, and the child(ren)'s personality (parent-assessed) explained 13.8%. Taken together, these results demonstrate the importance of considering the personality of both parents and children in the study of parental burnout.

How Will We React to the Discovery of Extraterrestrial Life?

How will humanity react to the discovery of extraterrestrial life? Speculation on this topic abounds, but empirical research is practically non-existent. We report the results of three empirical studies assessing psychological reactions to the discovery of extraterrestrial life using the Linguistic Inquiry and Word Count (LIWC) text analysis software. We examined language use in media coverage of past discovery announcements of this nature, with a focus on extraterrestrial microbial life (Pilot Study). A large online sample (N = 501) was asked to write about their own and humanity's reaction to a hypothetical announcement of such a discovery (Study 1), and an independent, large online sample (N = 256) was asked to read and respond to a newspaper story about the claim that fossilized extraterrestrial microbial life had been found in a meteorite of Martian origin (Study 2). Across these studies, we found that reactions were significantly more positive than negative, and more reward vs. risk oriented. A mini-meta-analysis revealed large overall effect sizes (positive vs. negative affect language: g = 0.98; reward vs. risk language: g = 0.81). We also found that people's forecasts of their own reactions showed a greater positivity bias than their forecasts of humanity's reactions (Study 1), and that responses to reading an actual announcement of the discovery of extraterrestrial microbial life showed a greater positivity bias than responses to reading an actual announcement of the creation of man-made synthetic life (Study 2). Taken together, this work suggests that our reactions to a future confirmed discovery of microbial extraterrestrial life are likely to be fairly positive.

Psychocultural Mechanisms of the Propensity toward Criminal Homicide: A Multidimensional View of the Culture of Honor

Introduction: Theory of the Culture of Honor is one of the few models in criminology specifically geared toward homicide. It proposes that, in certain societies, men must never show weakness and are required to react violently to any perceived threats to their reputation, thereby increasing their probability of committing a homicide. This has been suggested as the main explanation for the high rates of this type of crime in Brazil, particularly in the Northeast. Underlying this explanation there are complex mechanisms and processes that have yet to be clarified. Objectives: The present research aimed to investigate the workings of the possible psychocultural mechanisms underlying the culture of honor and the process through which they might affect the individual propensity toward homicide. Methods: A total of 336 Brazilian adults were assessed regarding a broad range of sociodemographic, psychological, and sociocultural variables, including their attitudes toward homicide. The resulting dataset was analyzed using Smallest Space Analysis and Facet Theory. Results: It seems that certain cultural elements associated to traditional masculinity and enhanced anger tend to promote negative personality traits and increase one's propensity toward committing homicide. Conclusion: The findings obtained not only confirm the Theory of the Culture of Honor for the propensity toward homicide, but also explicit and clarify some of the psychocultural processes and mechanisms involved, suggesting a new scientific framework.

What Is Your Faction? Multidimensional Evidence for the Divergent Series As the Basis for a New Model of Personality and Work Life

Introduction: The successful "Divergent" sci-fi trilogy by writer Veronica Roth portrays a dystopian and post-apocalyptic society where the population is divided into five groups called "Factions," each with a specific social role and associated to a specific set of psychological traits. Though fictional, such typology is compelling and may provide a significant contribution to personality studies. Objectives: To investigate the accuracy of the classification of psychological and sociocultural traits into five Factions as described in Divergent and their potential practical usefulness for understanding work life choices and experiences in organizations. Method: A total of 217 Brazilian adult men and women of various ages, socioeconomic status and ethnicities were submitted to measures of several psychological and sociocultural variables, as well as of how strongly they supposedly manifest each Faction. The resulting dataset was studied using Smallest Space Analysis (SSA) and Facet Theory. Results: The Factions were shown not only to be associated to psychological variables in ways consistent with the descriptions from Divergent, but also to be related to specific aspects of one's work life in organizations. Conclusion: The five Factions conceived by Roth appear to constitute an original set of constructs that are psychologically valid and, at the same time, of practical use in predicting work life choices and experiences. This justifies engaging in future empirical and theoretical work toward a new scientific model of potential practical value.
