Linking "big" personality traits to anxiety, depressive, and substance use disorders: a meta-analysis.

Abstract: We performed a quantitative review of associations between the higher order personality traits in the Big Three and Big Five models (i.e., neuroticism, extraversion, disinhibition, conscientiousness, agreeableness, and openness) and specific depressive, anxiety, and substance use disorders (SUD) in adults. This approach resulted in 66 meta-analyses. The review included 175 studies published from 1980 to 2007, which yielded 851 effect sizes. For a given analysis, the number of studies ranged from three to 63 (total sample size ranged from 1,076 to 75,229). All diagnostic groups were high on neuroticism (mean Cohen's d = 1.65) and low on conscientiousness (mean d = -1.01). Many disorders also showed low extraversion, with the largest effect sizes for dysthymic disorder (d = -1.47) and social phobia (d = -1.31). Disinhibition was linked to only a few conditions, including SUD (d = 0.72). Finally, agreeableness and openness were largely unrelated to the analyzed diagnoses. Two conditions showed particularly distinct profiles: SUD, which was less related to neuroticism but more elevated on disinhibition and disagreeableness, and specific phobia, which displayed weaker links to all traits. Moderator analyses indicated that epidemiologic samples produced smaller effects than patient samples and that Eysenck's inventories showed weaker associations than NEO scales. In sum, we found that common mental disorders are strongly linked to personality and have similar trait profiles. Neuroticism was the strongest correlate across the board, but several other traits showed substantial effects independent of neuroticism. Greater attention to these constructs can significantly benefit psychopathology research and clinical practice.

Personality and Coping

Abstract: Personality psychology addresses views of human nature and individual differences. Biological and goal-based views of human nature provide an especially useful basis for construing coping; the five-factor model of traits adds a useful set of individual differences. Coping—responses to adversity and to the distress that results—is categorized in many ways. Meta-analyses link optimism, extraversion, conscientiousness, and openness to more engagement coping; neuroticism to more disengagement coping; and optimism, conscientiousness, and agreeableness to less disengagement coping. Relations of traits to specific coping responses reveal a more nuanced picture. Several moderators of these associations also emerge: age, stressor severity, and temporal proximity between the coping activity and the coping report. Personality and coping play both independent and interactive roles in influencing physical and mental health. Recommendations are presented for ways future research can expand on the growing understanding of how personality and coping shape adjustment to stress.

Emotional intelligence: An integrative meta-analysis and cascading model.

Abstract: Research and valid practice in emotional intelligence (EI) have been impeded by lack of theoretical clarity regarding (a) the relative roles of emotion perception, emotion understanding, and emotion regulation facets in explaining job performance; (b) conceptual redundancy of EI with cognitive intelligence and Big Five personality; and (c) application of the EI label to 2 distinct sets of constructs (i.e., ability-based EI and mixed-based EI). In the current article, the authors propose and then test a theoretical model that integrates these factors. They specify a progressive (cascading) pattern among ability-based EI facets, in which emotion perception must causally precede emotion understanding, which in turn precedes conscious emotion regulation and job performance. The sequential elements in this progressive model are believed to selectively reflect Conscientiousness, cognitive ability, and Neuroticism, respectively. "Mixed-based" measures of EI are expected to explain variance in job performance beyond cognitive ability and personality. The cascading model of EI is empirically confirmed via meta-analytic data, although relationships between ability-based EI and job performance are shown to be inconsistent (i.e., EI positively predicts performance for high emotional labor jobs and negatively predicts performance for low emotional labor jobs). Gender and race differences in EI are also meta-analyzed. Implications for linking the EI fad in personnel selection to established psychological theory are discussed.

Testing Predictions From Personality Neuroscience Brain Structure and the Big Five

Abstract: We used a new theory of the biological basis of the Big Five personality traits to generate hypotheses about the association of each trait with the volume of different brain regions. Controlling for age, sex, and whole-brain volume, results from structural magnetic resonance imaging of 116 healthy adults supported our hypotheses for four of the five traits: Extraversion, Neuroticism, Agreeableness, and Conscientiousness. Extraversion covaried with volume of medial orbitofrontal cortex, a brain region involved in processing reward information. Neuroticism covaried with volume of brain regions associated with threat, punishment, and negative affect. Agreeableness covaried with volume in regions that process information about the intentions and mental states of other individuals. Conscientiousness covaried with volume in lateral prefrontal cortex, a region involved in planning and the voluntary control of behavior. These findings support our biologically based, explanatory model of the Big Five and demonstrate the potential of personality neuroscience (i.e., the systematic study of individual differences in personality using neuroscience methods) as a discipline.

A new look at the big five factor structure through exploratory structural equation modeling.

Abstract: NEO instruments are widely used to assess Big Five personality factors, but confirmatory factor analyses (CFAs) conducted at the item level do not support their a priori structure due, in part, to the overly restrictive CFA assumptions. We demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis (EFA), overcomes these problems with responses (N = 3,390) to the 60-item NEO-Five-Factor Inventory: (a) ESEM fits the data better and results in substantially more differentiated (less correlated) factors than does CFA; (b) tests of gender invariance with the 13-model ESEM taxonomy of full measurement invariance of factor loadings, factor variances-covariances, item uniquenesses, correlated uniquenesses, item intercepts, differential item functioning, and latent means show that women score higher on all NEO Big Five factors; (c) longitudinal analyses support measurement invariance over time and the maturity principle (decreases in Neuroticism and increases in Agreeableness, Openness, and Conscientiousness). Using ESEM, we addressed substantively important questions with broad applicability to personality research that could not be appropriately addressed with the traditional approaches of either EFA or CFA.

Personality and Civic Engagement: An Integrative Framework for the Study of Trait Effects on Political Behavior

Abstract: People’s enduring psychological tendencies are reflected in their traits. Contemporary research on personality establishes that traits are rooted largely in biology, and that the central aspects of personality can be captured in frameworks, or taxonomies, focused on five trait dimensions: openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability. In this article, we integrate a five-factor view of trait structure within a holistic model of the antecedents of political behavior, one that accounts not only for personality, but also for other factors, including biological and environmental influences. This approach permits attention to the complex processes that likely underlie trait effects, and especially to possible trait–situation interactions. Primary tests of our hypotheses draw on data from a 2006 U.S. survey, with supplemental tests introducing data from Uruguay and Venezuela. Empirical analyses not only provide evidence of the value of research on personality and politics, but also signal some of the hurdles that must be overcome for inquiry in this area to be most fruitful.

Intelligence and Personality as Predictors of Illness and Death: How Researchers in Differential Psychology and Chronic Disease Epidemiology Are Collaborating to Understand and Address Health Inequalities

Abstract: This monograph describes research findings linking intelligence and personality traits with health outcomes, including health behaviors, morbidity, and mortality. The field of study of intelligence and health outcomes, is called cognitive epidemiology, and the field of study of personality traits and health outcomes is known as personological epidemiology. Intelligence and personality traits are the principal research topics studied by differential psychologists, so the combined field could be called differential epidemiology. This research is important for the following reasons: The findings overviewed are relatively new, and many researchers and practitioners are unaware of them; the effect sizes are on par with better-known, traditional risk factors for illness and death; mechanisms of the associations are largely unknown, so they must be explored further; and the findings have yet to be applied, so we write this to encourage diverse interested parties to consider how applications might be achieved. To make this research accessible to as many relevant researchers, practitioners, policymakers, and laypersons as possible, we first provide an overview of the basic discoveries regarding intelligence and personality. We describe the nature and structure of the measured phenotypes (i.e., the observable characteristics of an individual) in both fields. Although both areas of study are well established, we recognize that this may not be common knowledge outside of experts in the field. Human intelligence differences are described by a hierarchy that includes general intelligence (g) at the pinnacle, strongly correlated broad domains of cognitive functioning at a lower level, and specific abilities at the foot. The major human differences in personality are described by five personality factors that are widely agreed on with respect to their number and nature: neuroticism, extraversion, openness, agreeableness, and conscientiousness. As a foundation for health-related findings, we provide a summary of research showing that intelligence and personality differences can be measured reliably and validly and are stable across many years (even decades), substantially heritable, and related to important life outcomes. Cognitive and personality traits are fundamental aspects of a person, and they have relevance to life chances and outcomes, including health outcomes. We provide an overview of major and recent research on the associations between intelligence and personality traits and health outcomes. These outcomes include mortality from all causes, specific causes of death, specific illnesses, and others, such as health-related behaviors. Intelligence and personality traits are significantly and substantially (by comparison with traditional risk factors) related to all of these outcomes. The studies we describe are unusual in psychology: They have large sample sizes (typically thousands of subjects, sometimes ~1 million), the samples are more representative of the background population than in most studies, the follow-up times are long (sometimes many decades, almost the whole human life span), and the outcomes are objective health measures (including death), not just self-reports. In addition to the associations, possible mechanisms for the associations are described and discussed, and some attempts to test these mechanisms are illustrated. It is relatively early in this research field, so a significant amount of work remains to be done. Finally, we make some preliminary remarks about possible applications, with the knowledge that the psychological predictors addressed are somewhat stable aspects of the person, with substantial genetic causes. Nevertheless, we believe differential epidemiology can be a useful component of interventions to improve individual and public health. Intelligence and personality differences are possible causes of later health inequalities; the eventual aim of cognitive and personological epidemiology is to reduce or eliminate these inequalities, to the extent that it is possible, and provide information to help people toward their own optimal health through the life course. We present these findings to a wider audience so that more associations will be explored, a better understanding of the mechanisms of health inequalities will be produced, and inventive applications will follow on the basis of what we hope will be seen as practically useful knowledge.

Personality Neuroscience and the Biology of Traits

Abstract: Personality neuroscience involves the use of neuroscience methods to study individual differences in behavior, motivation, emotion, and cognition. Personality psychology has contributed much to identifying the important dimensions of personality, but relatively little to understanding the biological sources of those dimensions. However, the rapidly expanding field of personality neuroscience is increasingly shedding light on this topic. This article provides a survey of progress in the use of neuroscience to study personality traits, organized using a hierarchical model of traits based on the Big Five dimensions: Extraversion, Neuroticism, Agreeableness, Conscientiousness, and Openness ⁄Intellect. Evidence is reviewed for hypotheses about the biological systems involved in each trait.

Compassionate Liberals and Polite Conservatives: Associations of Agreeableness With Political Ideology and Moral Values

Abstract: Political conservatism has been characterized by resistance to change and acceptance of inequality, with liberalism characterized by the polar opposite of these values. Political attitudes are heritable and may be influenced by basic personality traits. In previous research, conservatism (vs. liberalism) has been associated positively with Conscientiousness and negatively with Openness-Intellect, consistent with the association of conservatism with resistance to change. Less clear, however, are the personality traits relating to egalitarianism. In two studies, using a personality model that divides each of the Big Five into two aspects, the present research found that one aspect of Agreeableness (Compassion) was associated with liberalism and egalitarianism, whereas the other (Politeness) was associated with conservatism and traditionalism. In addition, conservatism and moral traditionalism were positively associated with the Orderliness aspect of Conscientiousness and negatively with Openness-Intellect. ...

Religiousness as a Cultural Adaptation of Basic Traits: A Five-Factor Model Perspective

Abstract: Individual differences in religiousness can be partly explained as a cultural adaptation of two basic personality traits, Agreeableness and Conscientiousness. This argument is supported by a meta-analysis of 71 samples (N = 21,715) from 19 countries and a review of the literature on personality and religion. Beyond variations in effect magnitude as a function of moderators, the main personality characteristics of religiousness (Agreeableness and Conscientiousness) are consistent across different religious dimensions, contexts (gender, age, cohort, and country), and personality measures, models, and levels, and they seem to predict religiousness rather than be influenced by it. The copresence of Agreeableness and Conscientiousness sheds light on other explanations of religiousness, its distinctiveness from related constructs, its implications for other domains, and its adaptive functions.

Genome-wide association scan for five major dimensions of personality.

Abstract: Personality traits are summarized by five broad dimensions with pervasive influences on major life outcomes, strong links to psychiatric disorders and clear heritable components. To identify genetic variants associated with each of the five dimensions of personality we performed a genome-wide association (GWA) scan of 3972 individuals from a genetically isolated population within Sardinia, Italy. On the basis of the analyses of 362 129 single-nucleotide polymorphisms we found several strong signals within or near genes previously implicated in psychiatric disorders. They include the association of neuroticism with SNAP25 (rs362584, P=5 × 10−5), extraversion with BDNF and two cadherin genes (CDH13 and CDH23; Ps<5 × 10−5), openness with CNTNAP2 (rs10251794, P=3 × 10−5), agreeableness with CLOCK (rs6832769, P=9 × 10−6) and conscientiousness with DYRK1A (rs2835731, P=3 × 10−5). Effect sizes were small (less than 1% of variance), and most failed to replicate in the follow-up independent samples (N up to 3903), though the association between agreeableness and CLOCK was supported in two of three replication samples (overall P=2 × 10−5). We infer that a large number of loci may influence personality traits and disorders, requiring larger sample sizes for the GWA approach to confidently identify associated genetic variants.

Identifying and profiling scholastic cheaters: their personality, cognitive ability, and motivation.

Abstract: Despite much research, skepticism remains over the possibility of profiling scholastic cheaters. However, several relevant predictor variables and newer diagnostic tools have been overlooked. We remedy this deficit with a series of three studies. Study 1 was a large-scale survey of a broad range of personality predictors of self-reported cheating. Significant predictors included the Dark Triad (Machiavellianism, narcissism, psychopathy) as well as low agreeableness and low conscientiousness. Only psychopathy remained significant in a multiple regression. Study 2 replicated this pattern using a naturalistic, behavioral indicator of cheating, namely, plagiarism as indexed by the Internet service Turn-It-In. Poor verbal ability was also an independent predictor. Study 3 examined possible motivational mediators of the association between psychopathy and cheating. Unrestrained achievement and moral inhibition were successful mediators whereas fear of punishment was not. Practical implications for researchers and educators are discussed.

Personality in nonhuman primates: a review and evaluation of past research.

Abstract: Scientific reports of personality in nonhuman primates are now appearing with increasing frequency across a wide range of disciplines, including psychology, anthropology, endocrinology, and zoo management. To identify general patterns of research and summarize the major findings to date, we present a comprehensive review of the literature, allowing us to pinpoint the major gaps in knowledge and determine what research challenges lay ahead. An exhaustive search of five scientific databases identified 210 relevant research reports. These articles began to appear in the 1930s, but it was not until the 1980s that research on primate personality began to gather pace, with more than 100 articles published in the last decade. Our analyses of the literature indicate that some domains (e.g., sex, age, rearing conditions) are more evenly represented in the literature than are others (e.g., species, research location). Studies examining personality structure (e.g., with factor analysis) have identified personality dimensions that can be divided into 14 broad categories, with Sociability, Confidence/Aggression, and Fearfulness receiving the most research attention. Analyses of the findings pertaining to inter-rater agreement, internal consistency, test-retest reliability, generally support not only the reliability of primate personality ratings scales but also point to the need for more psychometric studies and greater consistency in how the analyses are reported. When measured at the level of broad dimensions, Extraversion and Dominance generally demonstrated the highest levels of inter-rater reliability, with weaker findings for the dimensions of Agreeableness, Emotionality, and Conscientiousness. Few studies provided data with regard to convergent and discriminant validity; Excitability and Dominance demonstrated the strongest validity coefficients when validated against relevant behavioral criterion measures. Overall, the validity data present a somewhat mixed picture, suggesting that high levels of validity are attainable, but by no means guaranteed. Discussion focuses on delineating major theoretical and empirical questions facing research and practice in primate personality.

Prevalence and predictors of “subjective cognitive complaints” in the Sydney Memory and Ageing Study.

Abstract: Objectives To document the prevalence of self- and informant report of cognitive problems, usually referred to as "subjective cognitive complaints" (SCCs), in a community-dwelling sample of older adults and to examine the relationship between SCCs and objective impairment, mood, and personality measures. Participants Eight hundred twenty-seven nondemented community-dwelling adults aged 70–90 years. Measurements Participants were asked 24 SCC questions, including the Memory Complaint Questionnaire (MAC-Q), and completed neuropsychological testing in the domains of memory, language, executive function, visuospatial skills, and psychomotor speed. The Geriatric Depression Scale, Goldberg Anxiety Scale, and Neuroticism, Openness, and Conscientiousness from the NEO-Five Factor Inventory were used as measures of participants' psychological status. Informants completed 19 SCC questions, including a modified short Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Results Overall, 95.5% of participants or their informants endorsed at least one SCC. Although participants were more likely to endorse a memory complaint, informants seemed more accurate in endorsing a complaint when cognitive impairment was objectively present. SCC correlated with participants' scores on measures of depression, anxiety, neuroticism, and inversely with measures of openness and conscientiousness. Age, education, and sex had little impact on these effects. Regression analysis showed that psychological factors explained the number of complaints more than cognitive performance. Conclusions The usefulness of SCCs as a criterion for mild cognitive impairment is questioned because of their high prevalence and their relationship to psychological factors. This may be helpful for clinicians to bear in mind when presented with patients with cognitive complaints.

The Five-Factor Framing of Personality and Beyond: Some Ruminations

Abstract: The five-factor conceptualization of personality has been presented as all-embracing in understanding personality and has even received authoritative recommendation for understanding early development. I raise various concerns regarding this popular model. More specifically, (a) the atheoretical nature of the five-factors, their cloudy measurement, and their inappropriateness for studying early childhood are discussed; (b) the method (and morass) of factor analysis as the exclusive paradigm for conceptualizing personality is questioned and the continuing nonconsensual understandings of the five-factors is noted; (c) various unrecognized but successful efforts to specify aspects of character not subsumed by the catholic five-factors are brought forward; and (d) transformational developments in regard to inventory assessment of personality are mentioned. I conclude by suggesting that repeatedly observed higher order factors hierarchically above the proclaimed five may promise deeper biological understanding...

Employee personality as a moderator of the relationships between work stressors and counterproductive work behavior.

Abstract: The current study, which is framed within the context of the Transactional Theory of Stress and Coping, examined counterproductive work behaviors (CWBs) as a response to ineffective coping with work stressors. More specifically, we examined whether the relationship between work stressors and CWBs was moderated by employee personality. Analyses using data collected from 726 adults employed in a diverse set of occupations found that work stressors were more strongly related to CWBs among workers who were low in conscientiousness, or high in negative affectivity (NA) than among workers who were high in conscientiousness, or low in NA. We found less consistent support, however, for the moderating effects of agreeableness.

Personality and Health, Subjective Well-Being, and Longevity

Abstract: Personality traits can be employed to guide understanding of trajectories to health and longevity, but long-term longitudinal study and multifaceted assessment of healthy aging are crucial. Following up on the life span study initiated by Lewis Terman, we assessed 4 validated factors of personality in young adulthood in 1940, constructed a multifactor measure of participants' healthy aging in 1986, and collected death certificates through 2007 (to determine longevity) on a sample of 1,312 Terman participants (732 men). Neuroticism predicted worse physical health and subjective well-being in old age and, for women, higher mortality risk, but for men, neuroticism predicted decreased mortality risk. For both sexes, extraversion predicted old-age social competence, whereas conscientiousness predicted men's old-age productivity. Differential patterns of association between personality traits and healthy aging components are informative about individual personality characteristics and long-term health outcomes.

The genetic and environmental relationship between major depression and the five-factor model of personality.

Abstract: BackgroundCertain personality traits have long been suspected to reflect an enduring vulnerability to major depression (MD) in part because of shared genetic risk factors. Although many have agreed that normative personality is well captured by the ‘Big-Five’ personality traits of Openness (O), Conscientiousness (C), Extraversion (E), Agreeableness (A) and Neuroticism (N), to date genetically informative studies have only examined the relationship between MD and N and E.MethodQuestionnaires were completed on a website, yielding a sample of 44 112 subjects including both members of 542 same-sex twin pairs. Personality was measured by the Big Five Inventory. Structural modeling was performed by Mx.ResultsThree of the big-five personality traits – O, E and A – had small phenotypic associations with risk for MD and small genetic correlations. Two traits – N and C – had stronger phenotypic associations (positive for N and negative for C) with the following estimates of the genetic correlation with MD: +0.43 for N and −0.36 for C. N and C were moderately negatively correlated. Controlling for N reduced the genetic correlation between C and MD more than controlling for C reduced the genetic correlation between N and MD.ConclusionsA large proportion of the genetic risk for MD that is expressed via personality is captured by N, with a modest amount due to C, and small amounts from O, E and A.

High neuroticism and low conscientiousness are associated with interleukin-6.

Abstract: BackgroundHigh Neuroticism and low Conscientiousness are frequently implicated in health-risk behaviors, such as smoking and overeating, as well as health outcomes, including mortality. Their associations with physiological markers of morbidity and mortality, such as inflammation, are less well documented. The present research examines the association between the five major dimensions of personality and interleukin-6 (IL-6), a pro-inflammatory cytokine often elevated in patients with chronic morbidity and frailty.MethodA population-based sample (n=4923) from four towns in Sardinia, Italy, had their levels of IL-6 measured and completed a comprehensive personality questionnaire, the NEO-PI-R. Analyses controlled for factors known to have an effect on IL-6: age; sex; smoking; weight; aspirin use; disease burden.ResultsHigh Neuroticism and low Conscientiousness were both associated with higher levels of IL-6. The findings remained significant after controlling for the relevant covariates. Similar results were found for C-reactive protein, a related marker of chronic inflammation. Further, smoking and weight partially mediated the association between impulsivity-related traits and higher IL-6 levels. Finally, logistic regressions revealed that participants either in the top 10% of the distribution of Neuroticism or the bottom 10% of conscientiousness had an approximately 40% greater risk of exceeding clinically relevant thresholds of IL-6.ConclusionsConsistent with the literature on personality and self-reported health, individuals high on Neuroticism or low on Conscientiousness show elevated levels of this inflammatory cytokine. Identifying critical medical biomarkers associated with personality may help to elucidate the physiological mechanisms responsible for the observed connections between personality traits and physical health.

Persuasive robotic assistant for health self-management of older adults: Design and evaluation of social behaviors

Abstract: Daily health self-management, such as the harmonization of food, exercise and medication, is a major problem for a large group of older adults with obesity or diabetics. Computer-based personal assistance can help to behave healthy by persuading and guiding older adults. For effective persuasion, the assistant should express social behaviors (e.g., turn taking, emotional expressions) to be trustworthy and show empathy. From the motivational interviewing method and synthetic assistants' literature, we derived a set of social behaviors, and implemented a subset in a physical character, a virtual character and a text interface. The first behavior type concerns conversing with high-level dialogue (semantics, intentions), which could be implemented in all 3 assistants. The other behavior types could only be implemented in the characters: showing natural cues (e.g., gaze, posture), expressing emotions (e.g., compassionate face), and accommodating social conversations (e.g., turn taking). In an experiment, 24 older adults (45-65) interacted with the text interface and one of the characters, conform a ''one-week diabetics scenario''. They experienced the virtual and physical character as more empathic and trustworthy than the text-based assistant, and expressed more conversational behavior with the characters. However, it seems that the preference of interacting with the character or the text interface was influenced by the conscientiousness of the participant; more conscientious people liked the text interface better. Older adults responded more negative to the characters that lacked the social behaviors than to the text interface. Some differences between the virtual and physical character probably occurred due to the specific constraints of the physical character.

Who is James Bond? : the Dark Triad as an agentic social style

Abstract: If the Dark Triad are costly traits for individuals to have and individuals are predisposed to avoid interacting with selfish individuals, how do those who have those traits extract resources from their environment? We contend that a specific set of personality traits will enable individuals to do so. We showed that those who are disagreeable, extraverted, open, and have high self-esteem along with low levels of neuroticism and conscientiousness score high on the Dark Triad (Study 1: N = 216). Additionally, having a more individualistic and competitive approach to others and not a strongly altruistic orientation will also help those who are high on the Dark Triad (Study 2; N = 336). We contend that the Dark Triad may represent one social strategy that is characterized by an agentic social style.
