Trait aggression has been studied for decades and yet remains adrift from broader frameworks of personality such as the Five Factor Model. Across two datasets from undergraduate participants (Study 1: N = 359; Study 2; N = 620), we observed strong manifest and latent correlations between trait aggression and lower agreeableness (i.e., greater antagonism). Trait aggression was also linked to greater neuroticism and lower conscientiousness, but their effect sizes fell beneath our preregistered threshold. Subsequent item-level analyses were unable to articulate trait aggression and agreeableness items into separate factors using the IPIP-NEO, but not the Big Five Inventory...

Large-scale health crises, such as the COVID-19 pandemic, may evoke negative affective responses, which are linked to psychological maladjustment and psychopathology. Here, we shed light on the role of the personality trait neuroticism in predicting who experiences negative affective responses. In a large-scale experience-sampling study ( N  = 1,609; 38,120 momentary reports), we showed that individuals high in neuroticism experienced more negative affect and higher affective variability in their daily lives...

This research uses the Health and Retirement Study to identify psychological and social factors that prospectively predict new reports of perceived weight discrimination among individuals who measure in the obese weight category. Participants (Mage =66.89, SD=8.33; 58% women) reported on their personality and social isolation, had a body mass index (BMI)≥30, reported no perceived weight discrimination at baseline, and completed at least one assessment over the up to 8-year follow-up ( N =3,064). Eleven percent of participants reported new experiences of perceived weight discrimination...

Although individuals vary in how optimistic they are about the future, one assumption that researchers make is that optimism is sensitive to changes in life events and circumstances. We examined how optimism and pessimism changed across the lifespan and in response to life events in three large panel studies (combined N = 74,886). In the American and Dutch samples, we found that optimism increased across younger adulthood, plateaued in midlife, and then decreased in older adulthood. In the German sample, there were inconsistent results with respect to age differences and mean level changes in optimism...

In preregistered secondary data analyses, we compared the predictive utility of trait affect and average daily affect for predicting three health outcomes across nine years (N = 1,376). Trait positive and negative affect were assessed using a 25-item dispositional questionnaire. Average daily affect was assessed as the mean of eight daily diary reports of the same items. Trait affect and average daily affect both had medium associations with self-reported general health and chronic health conditions. Moreover, both types of affect predicted mortality when adjusting for baseline health and demographics...

Since the historical conception of psychopathy, researchers have been interested in understanding moral functioning among psychopathic individuals. The present study investigated the association between psychopathic traits and moral intuitions among incarcerated juvenile offenders ( N = 178). Participants were assessed using the Psychopathy Checklist:Youth Version (Forth et al., 2003) and the Moral Foundations Questionnaire (Graham et al., 2011), which defines five core moral foundations: Harm/care, Fairness/reciprocity, Ingroup/loyalty, Authority/respect, and Purity/sanctity...

Negative urgency is a trait that is a risk factor for a range of psychopathology. Yet, little research has tested whether global self-report measures of negative urgency truly reflect a heightened association between real-world negative emotions and impulsive behaviors. In a sample of young adults (N = 222) assessed 3 times per day for 10 days, we tested whether negative emotions were associated with multiple facets of impulsivity at the state-level, and whether those associations were moderated by global self-report of negative urgency...

This study examines the developmental influences of occupational environments on personality traits from childhood to adulthood. We test aspects of a theory of vocational and personality development, proposing that traits develop in response to work experience following corresponsive and noncorresponsive mechanisms. We describe these pathways in the context of situations of vocational gravitation and inhabitation. In a sample from the Hawaii personality and health cohort ( N = 596), we examined associations of childhood and adulthood personality traits, with occupational environments profiled on the RIASEC model...

Background: There is strong evidence that adverse childhood experiences (ACEs) negatively impact mental health. However, the association between ACEs and personality, emotions and affect are poorly understood. Therefore, we examined the association between composite ACE score and ACE type and personality, emotions and positive and negative affect. Methods: Three waves of data from the Midlife Development in the United States (MIDUS) study were used. ACE was the primary independent correlate...

We reexamined the psychometric properties of the Momentary Impulsivity Scale (MIS) in two young adult samples using daily diary ( N =77) and ecological momentary assessment ( N =147). A one-factor between- and within-person structure was supported, though "I felt impatient" loaded poorly within-person. MIS scores consistently related to emotion-driven trait impulsivity; however, MSSDs of MIS scores were unrelated to outcomes after accounting for aggregate MIS scores. We observed positive, within-person correlations with negative, but not positive, affect...

Across two studies, the current research investigated how different dimensions of narcissism (grandiosity/agentic extraversion, entitlement/self-centered antagonism, vulnerability/narcissistic neuroticism) relate to social networking site (SNS) use and behaviors. Study 1 employed a community sample of young adults, whereas Study 2 examined college students. Participants completed assessments of narcissism and SNS use through an online survey. Grandiosity/agentic extraversion was generally associated with greater levels of downward social comparison relative to the other two dimensions...

The aims of the present study were as follows: (1) Using a large sample of adults, estimate overlap between social-relational exposures measured at midlife and well-being measured at midlife and approximately 9-years later. (2) Using a subsample of twins, test for heritable variation in social-relational exposures, and (3) controlling for heritable and shared environmental variation, estimate overlap between social-relational exposures and well-being, both concurrently and approximately 9-years later. Results indicated small-to-moderate overlap between exposures and well-being (mean r = ...

Personality is related to psychopathology and its higher-order structures, but there is little research regarding neurobiological associations of higher-order psychopathology factors. This study examined the factor structure of a wide range of psychopathology and its associations with both personality and emotional reactivity revealed through the late positive potential (LPP) in a sample of 275 undergraduates. A three-factor structure of psychopathology emerged comprising Internalizing (INT), Externalizing (EXT), and Aberrant Experiences (ABX)...

Evidence suggests that employment may buffer against the negative health outcomes associated with borderline personality disorder (BPD). The purpose of the current analyses was to examine unemployment and the BPD-health relationship prospectively. Participants were 1,536 older adults in a longitudinal study of health and aging, with repeated measures of physical health, depressive symptoms, and life satisfaction. We measured BPD features using multiple sources at baseline, and used principal components analysis to obtain latent scores...

We first confirmed adolescents diagnosed with disruptive behavior disorders (oppositional defiant, conduct disorder; n = 158) had lower constraint and higher negative emotionality, and greater psychiatric comorbidity and psychosocial dysfunction, relative to adolescents without ( n = 755), in a population-based sample enriched for externalizing psychopathology (mean age = 17.90 years; 52% female). We then explored whether different personality types, defined by patterns of personality identified via latent profile analysis, were differently associated with clinical features in adolescents with a disruptive behavior disorder diagnosis...

Personality traits such as conscientiousness and impulsivity correlate with temporal discounting, the degree to which individuals discount the value of future relative to present rewards. These variables have, in turn, been hypothesized to relate to income inequality in the United States. A key but untested assumption of this hypothesis is that the association among these variables is distinct across socioeconomic classes. The purpose of the present research is to test that assumption. N = 1,100 adults with annual income ranging from at or below the poverty line ($0-$20,000) to upper-middle class ($200,000+) completed personality measures and a measure of temporal discounting...

Personality and sleep predict longevity; however, no investigation has tested whether sleep mediates this association. Thus, we tested this effect across a 20-year follow-up (N = 3,759) in the Midlife Development in the United States cohort (baseline M age = 47.15) using proportional hazards in a structural equation modeling framework. Lower conscientiousness predicted increased death risk via the direct, indirect, and total effect of quadratic sleep duration. Although there were no other direct personality-mortality effects, higher neuroticism and agreeableness and lower conscientiousness predicted increased death risk via the joint indirect effects of quadratic sleep duration and higher daytime dysfunction...

Two dimensional, hierarchical classification models of personality pathology have emerged as alternatives to traditional categorical systems: multi-tiered models with increasing numbers of factors and models that distinguish between a general factor of severity and specific factors reflecting style. Using a large sample ( N =840) with a range of psychopathology, we conducted exploratory factor analyses of individual personality disorder criteria to evaluate the validity of these conceptual structures. We estimated an oblique, "unfolding" hierarchy and a bifactor model, then examined correlations between these and multi-method functioning measures to enrich interpretation...

Disinhibition has been a construct of interest for decades, as evidenced by its inclusion in most prominent models of general personality functioning and its link to personality pathology, other psychopathology, health behaviors, and public health concerns. Disinhibition is manifest in behavioral, task based, and physiological measures, and common etiologies are a major reason for the coherence of the domain across a variety of assessment modalities. The current review will provide a summary of the conceptualization of the construct across prominent models, its link to psychopathology and maladaptive behaviors, and its etiology...

This study assessed early adolescent positive and negative affect as long-term predictors of romantic conflict, anxious and avoidant attachment, romantic and social competence, and relationship satisfaction in adulthood utilizing a longitudinal, multi-informant study of 166 participants assessed annually at ages 14-17, and again at ages 23-25. Positive affect in adolescence predicted greater self-rated social competence during late adolescence and greater self-rated romantic competence and less partner-reported hostile conflict almost a decade later...
