This review of 115 longitudinal studies involving 45,000 marriages emphasizes that relationship success is a dynamic trajectory, not a static state. By evaluating decades of data, the authors developed an integrative model showing how individual vulnerabilities, external stressors, and adaptive c...

This study investigated how different groups—including parents, friends, and strangers—agree on an individual's personality traits. Researchers found that while knowing a person in the same context helps, it is not required for agreement; in fact, acquaintances who had never met agreed as much as...

This longitudinal study followed a cohort of gifted children across several decades to determine how personality and family stress impact longevity. Researchers discovered that psychosocial factors, particularly impulsive or undercontrolled personality traits and the experience of parental divorc...

This study highlights how the NEO PI-R and its 30 specific traits can be applied to vocational counseling and job placement. By using the NEO Job Profiler alongside the inventory, researchers can identify the specific personality requirements of an occupation, such as law enforcement. This dual a...

This research explains the hierarchical structure of the NEO-PI-R, where five broad personality domains are each supported by six specific facets. While domain-level scores provide a quick overview of an individual, analyzing the facets offers a more precise psychological profile. This multi-leve...

This longitudinal study demonstrates that behavioral styles identified at age 3 are significant predictors of personality traits in young adulthood. By age 18, 'Undercontrolled' children emerged as impulsive and aggressive, while 'Inhibited' children remained socially cautious and low in danger-s...

This study confirms the Five-Factor Model (FFM) effectively distinguishes individuals with Axis I disorders from those without. Across 468 young adults, personality dimensions provided unique diagnostic insights, even when accounting for general psychopathological symptoms. These findings highlig...

This historical overview traces the evolution of the Big Five factor structure, which has become the dominant framework for studying individual differences. The taxonomy is rooted in the 'lexical hypothesis,' the idea that important personality traits are eventually encoded into language. Its dev...

This study connects James Marcia’s four identity statuses—Achievement, Foreclosure, Moratorium, and Diffusion—to the Big Five traits. Researchers found that Identity Achievers exhibit high Conscientiousness and Extraversion with low Neuroticism. Conversely, Foreclosure correlates with low Opennes...

This landmark study identifies five robust and recurring personality factors (Surgency, Agreeableness, Dependability, Emotional Stability, and Culture) which served as the foundational precursors to the modern Big Five. By analyzing 35 traits across eight highly diverse samples (ranging from airm...

The Five-Factor Model (FFM) organizes personality into five broad, hierarchical dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Extensive research using diverse instruments and cross-cultural observers validates its comprehensiveness. Beyond si...

The Abridged Big Five Dimensional Circumplex (AB5C) model serves as a bridge between the hierarchical 'simple-structure' Big Five and traditional circumplex models. By pairing each of the Big Five factors into ten distinct circles, it defines personality facets as 'blends' of two primary dimensio...

Researchers investigated how to create the most accurate and 'univocal' (single-factor) measures for the Big Five personality domains. They discovered that while transparent bipolar scales (which use opposing pairs of adjectives) perform well, simple unipolar scales using 100 individual terms are...

This meta-analysis explores how the Big Five personality traits predict success across various career fields, such as sales, management, and law enforcement. The research identifies Conscientiousness as a universal predictor of high job performance regardless of the occupation. Other traits are m...

This study identifies that overall physical attractiveness is a composite of both static and dynamic components. Through structural equation modeling, researchers found that while facial beauty is a primary static factor, dynamic elements (such as social and communication skills) contribute signi...

This study details the evolution of the NEO Personality Inventory into its revised version (NEO-PI-R). Researchers expanded the model by developing specific 'facet' scales for Agreeableness (such as Trust and Altruism) and Conscientiousness, including Order and Self-Discipline. By testing these m...

This study critiques the MBTI's theoretical foundations, finding no evidence for 'dichotomous types' or Jungian categories. Instead, data from 468 participants shows the MBTI measures four continuous dimensions that align closely with the Five-Factor Model. Specifically, the MBTI indices map onto...

Research comparing the interpersonal circumplex with the Five-Factor Model reveals that the circumplex is primarily defined by two axes: Extraversion and Agreeableness. Data from self, peer, and spouse ratings confirm that this circular arrangement is a genuine structural feature of personality, ...

This study confirms the robustness of the Five-Factor Model (FFM) by demonstrating significant agreement between self-reports and peer ratings. Using both adjective factors and questionnaire scales, researchers found substantial cross-observer correlations (r=.25 to .62) across all five domains: ...
