Research involving over 150 longitudinal studies demonstrates that personality trait consistency increases significantly as individuals age, following a clear upward trajectory before stabilizing. Correlation coefficients rise from .31 in childhood to .64 by age 30, eventually reaching a plateau ...

This research identifies five robust dimensions of spirituality that constitute the Expressions of Spirituality Inventory (ESI): Cognitive Orientation, Experiential/Phenomenological, Existential Well-Being, Paranormal Beliefs, and Religiousness. While these dimensions correlate differentially wit...

This research confirms a robust relationship between Extraversion and pleasant affect, finding moderate to strong correlations across various assessment scales. However, the method of measurement significantly impacts the results. Global, retrospective reports (where individuals recall their mood...

This study of leaders across 200 organizations found that Extraversion and Agreeableness are the strongest predictors of transformational leadership behavior. While Openness to Experience showed an initial positive correlation, its impact vanished when controlling for other traits, and Neuroticis...

This study of 343 participants highlights Conscientiousness as a vital predictor of health-conscious behaviors, particularly those involving household safety. High levels of this trait led to more restrictive smoking rules at home, suggesting that self-disciplined individuals are more proactive i...

Successful identity consolidation involves committing to adult roles and constructing a coherent sense of self. Research on women shows that ego-resiliency at age 21 predicts better identity outcomes by age 27, a process often mediated by the quality of their experience in marriage. Notably, achi...

Drawing from the longitudinal Intergenerational Studies, this research proves that personality and cognitive ability independently drive career success. Conscientiousness consistently predicted both job satisfaction and higher income, while Neuroticism hindered extrinsic achievements. Furthermore...

Meta-analytic research spanning 85 years identifies General Mental Ability (GMA) as the premier predictor of professional success. Pairing GMA with integrity tests or structured interviews yields the highest predictive validity (up to .65), effectively measuring both cognitive capacity and behavi...

This meta-analysis of 137 personality constructs identifies how specific traits drive subjective well-being. While personality strongly predicts life satisfaction and happiness, it is less predictive of negative affect. Within the Big Five, Neuroticism stands as the primary predictor of overall s...

This research examines how authoritarian and submissive personalities develop through social learning rather than innate traits. Submissiveness often originates from adolescent training in obedience and conventionalism. Conversely, authoritarians tend to be ethnocentric and maintain double standa...

This work introduces foundational research in personality measurement, emphasizing key issues such as the nature of psychological constructs, as well as the importance of reliability and validity. It highlights measurement approaches that not only assess traits but also advance theoretical unders...

Psychological defense is the process of regulating painful emotions like anxiety and loss of self-esteem, often through unconscious mental processes. While early theories focused on internal conflicts regarding sex and aggression, more primitive mechanisms like denial protect against external rea...

This chapter explores how individuals maintain behavioral consistency by actively selecting environments that align with their traits. This 'person-situation fit' suggests that stability in behavior across time is not just an internal mechanism but a result of people choosing settings where their...

This review examines the evolution and structure of extraversion, tracing its development from early typological views to modern trait-based models. It integrates foundational theories with contemporary perspectives linking extraversion to affect and personality frameworks. The authors propose a ...

This study explores how intelligence, personality, and vocational interests overlap. It distinguishes between intelligence as 'maximal performance' (testing well) and 'typical performance' (everyday thinking). By analyzing these connections, the researchers identified four 'trait complexes'—socia...

The study of how individuals manage stress has evolved through three distinct theoretical generations. Early psychoanalytic models initially merged personality and coping as one, while the subsequent transactional approach shifted focus toward situational factors and cognitive appraisals. The cur...

Research identifies three replicable personality types among adolescents (Resilients, Overcontrollers, and Undercontrollers) that generalize across different racial backgrounds. Resilients are characterized by high intelligence and ego resiliency, leading to academic success and low delinquency. ...

This meta-analysis of 45 studies identifies hostility as an independent risk factor for coronary heart disease (CHD) and all-cause mortality. Using structured interviews to measure hostile potential yielded a correlation of r=.18 with CHD. Notably, the Cook-Medley Hostility Scale and similar cogn...

Holland's typology emphasizes that professional flourishing depends on congruence between an individual’s personality and their work environment. When a person's RIASEC type aligns with their workplace characteristics, they experience higher job satisfaction, stability, and performance; conversel...
