This meta-analysis of 62,000 employees confirms that positive and negative affect are powerful, independent drivers of job attitudes. Negative affect strongly predicts emotional exhaustion, while positive affect enhances job satisfaction and personal accomplishment. Because both affects contribute uniquely, workplace well-being requires more than just reducing stress; it necessitates fostering positive emotional states to improve organizational commitment and reduce turnover intentions.

This longitudinal research reveals a reciprocal relationship between personality and professional life during the transition into adulthood. While personality traits at age 18 significantly predict both objective and subjective work experiences by age 26, the reverse is also true: early career experiences actively shape personality development. Most notably, the study identifies a 'corresponsive' effect, where the same traits that lead an individual to choose a specific career path are further strengthened and reinforced by the demands of that environment.

This study confirms that the Big Five personality factors are reliable predictors of significant real-world behaviors, such as academic performance and alcohol consumption. By testing two independent samples using three different assessment tools (including traditional verbal inventories and an experimental nonverbal measure) researchers found consistent behavioral patterns across all versions. These results provide strong construct validity for the Big Five model, demonstrating that these five traits are not just theoretical abstractions but stable determinants of complex human actions in social and cultural contexts.

This updated research confirms that personality traits remain remarkably stable after age 30, significantly shaping individual adaptation and the life course. Through extensive longitudinal and cross-cultural studies, the authors demonstrate that the Five-Factor Model provides a reliable framework for measuring these enduring dispositions. While life circumstances change, core traits act as a consistent foundation, influencing how adults navigate challenges and maintain their psychological identity over decades.

This study examines how life milestones and personality traits affect relationships between 26-year-olds and their parents. Relationships tend to be more positive when young adults are married, employed, and living independently. However, personality plays a distinct role: higher levels of negative emotionality and lower self-control in young adults correlate with more strained parent-child dynamics, regardless of their life achievements.

This study examines the connection between the Big Five personality traits and Holland’s RIASEC occupational types. The findings reveal that while these models overlap, they measure distinct aspects of an individual. The strongest links exist between Enterprising roles and Extraversion, as well as Artistic roles and Openness to Experience. In contrast, the 'Realistic' type showed almost no correlation with the Big Five, suggesting that personality and vocational interests provide unique, complementary insights into a person's profile.

Volunteerism is defined as long-term, planned prosocial behavior that benefits strangers within an organizational context. This research highlights that sustained service is driven by both dispositional variables (such as specific personality traits and religiosity) and organizational factors, such as the volunteer environment and management style. By presenting a theoretical model of these combined influences, the study suggests that the most effective way to foster community service is to understand how an individual's internal motivations interact with the structural support of the organization.

This longitudinal study demonstrates a reciprocal relationship between stable personality traits and the quality of romantic relationships in young adulthood. Personality assessed at age 18 significantly predicted relationship quality, conflict, and abuse at age 26, suggesting that individual differences create consistent patterns even across different partners. Simultaneously, relationship experiences influenced personality development over time. These findings indicate that while relationships can impact the individual, a person’s inherent traits often determine whether their romantic unions thrive or fail, underscoring the importance of considering personality as a fundamental driver of relational outcomes.

This meta-analysis identifies hostility as an independent risk factor for coronary heart disease (CHD) and all-cause mortality. The research distinguishes between different measurement methods, finding that structured interviews focusing on the 'potential for hostility' are particularly effective at predicting CHD. Meanwhile, cognitive-experiential measures, such as the Cook-Medley Hostility Scale, prove highly predictive of overall mortality. Despite an increase in null findings from recent high-risk studies, the overall evidence suggests that chronic hostility functions as a significant psychological contributor to cardiovascular decline and shortened lifespan.

This research contrasts three perspectives on romantic dynamics (similarity, complementarity, and exchange) to determine which best predicts relationship outcomes. The findings indicate that exchange, or the interaction of socially valuable attributes, is the strongest predictor of satisfaction. Interestingly, the study found a negative correlation with similarity, suggesting that couples with dissimilar personality traits and attachment styles were actually more satisfied. While complementarity did not influence satisfaction, it was the primary driver of commitment, particularly when partners possessed complementary personalities.

Research across four studies identifies gratitude as a distinct disposition strongly linked to higher well-being, prosociality, and spirituality. Notably, the grateful disposition is negatively associated with envy and materialism. These relationships remain significant even when controlling for Big Five traits like Extraversion, Neuroticism, and Agreeableness, proving that gratitude offers unique psychological insights beyond general personality. To facilitate future research, the authors developed the Gratitude Questionnaire (GQ-6), a highly reliable unidimensional scale.

This meta-analysis identifies robust links between Holland’s Big Six vocational interests and the Big Five personality domains. The strongest connections include Artistic with Openness (r=.48), Enterprising with Extraversion (r=.41), and Social with Extraversion (r=.31). These findings indicate that career interests are not distinct from personality; rather, they serve as specific, practical expressions of a person's broader dispositional traits in a professional context.

This comprehensive meta-analysis of 163 samples confirms that personality is a significant dispositional source of job satisfaction. When organized under the Big Five framework, the traits collectively show a strong multiple correlation of .41 with how much people enjoy their work. Neuroticism was the strongest negative predictor, while Conscientiousness and Extraversion were the most potent positive predictors. Notably, only the effects of Neuroticism and Extraversion consistently generalized across different types of studies, suggesting they are the most stable personality drivers of workplace contentment regardless of the specific job context.

This longitudinal research identifies Agreeableness as the primary personality dimension influencing adolescent peer relations and social safety. While both Agreeableness and Extraversion correlate with peer acceptance, Agreeableness uniquely serves as a protective shield against victimization. Specifically, high Agreeableness moderates behavioral vulnerabilities; for agreeable children, these vulnerabilities do not lead to increased bullying, whereas less agreeable children experience a direct correlation between behavioral risks and victimization over time.

This study provides evidence for the 'broaden-and-build' theory, which suggests that positive emotions expand a person's cognitive and behavioral repertoire. Researchers found a reciprocal relationship where initial positive affect led to improved broad-minded coping strategies, which in turn increased future positive affect. This 'upward spiral' effect was unique to positive emotions, as negative affect did not show the same predictive power over coping mechanisms. The results suggest that fostering positive emotional states can serially enhance well-being and resilience over time.

This study bridges the gap between normal personality traits and personality disorders by examining 'socially undesirable' language. By mapping maladaptive terms onto the Big Five poles, researchers found that personality disorders are essentially extreme, socially problematic versions of standard traits. This lexical approach reinforces the Five-Factor Model’s ability to categorize dysfunctional behavior, suggesting that maladaptive personality is a matter of degree rather than a separate category.

This research highlights how a strong sense of humor acts as a powerful social asset by shaping how others perceive our personality. Across two studies, observers consistently linked a 'well above average' sense of humor to a suite of socially desirable traits. Specifically, individuals with a great sense of humor are perceived as being significantly higher in Agreeableness and lower in Neuroticism compared to those with a typical or below-average sense of humor. These findings suggest that humor doesn't just make people laugh; it generates a 'halo effect' of positive expectations, leading others to view the humorous person as more emotionally stable and socially cooperative.

This research identifies three core personality prototypes (resilient, overcontrolled, and undercontrolled) that remain consistent from childhood through adulthood. Resilient individuals show high adaptability, while overcontrollers tend to internalize their emotions and undercontrollers often externalize their behaviors. By confirming these patterns across different ages and evaluation methods, the study provides a powerful, high-level framework for understanding how distinct personality types interact with the social world.

While the broad Big Five factors are useful, this study proves that narrow personality facets significantly improve predictive accuracy. In tests against 40 behavioral criteria, specific sub-traits outperformed broad factors, capturing significant variance that the Big Five missed. These results advocate for a more granular approach to personality assessment, suggesting that measuring specific facets provides a far more precise and effective understanding of human behavior.

This meta-analysis of 59 studies demonstrates that personality research provides a powerful lens for understanding criminology. By comparing four major structural models—PEN, the three-factor model, the FFM, and the seven-factor model—the authors found that antisocial behavior consistently correlates with specific traits. Regardless of the framework used, the strongest predictors of antisocial behavior are low Agreeableness and low Conscientiousness. These results suggest that the 'core' of criminal and antisocial tendencies lies in a lack of empathy, poor impulse control, and a disregard for social norms, providing a unified psychological profile for future criminological research.
