A curated collection of research papers, articles, and related news and media exploring the Big Five personality traits.
Across two studies (cross-sectional and 4-wave longitudinal), "healthy personality"—higher extraversion, agreeableness, conscientiousness, openness, plus lower neuroticism—consistently predicted higher well-being (mental health, life satisfaction, worthwhileness), driven mainly by overall trait elevation rather than resemblance to a specific personality "profile." Healthy personality did predict higher levels, but not stability or change, in well-being or psychological richness (novelty, challenge, perspective shifts) over time.
This study compared 125 older adults (71–101 years) from Sardinia's Blue Zone versus a nearby non-Blue Zone. Openness, conscientiousness, and agreeableness correlated with better psychological well-being; neuroticism correlated with lower Health-Related Quality of Life (HRQoL). Blue Zone residents showed higher openness, better coping and emotional competence, and more leisure engagement than non-Blue Zone peers, suggesting adaptive personality traits and active lifestyles jointly support successful aging in this exceptional-longevity population.
Analyzing four large panels (N=63,502), this study found reciprocal, small effects between loneliness and Big Five traits over 4-year intervals. Higher-than-typical extraversion, conscientiousness, and emotional stability each predicted lower subsequent loneliness (βs ≈ -0.02 to -0.04). Conversely, elevated loneliness predicted later declines in extraversion, conscientiousness, and emotional stability (βs ≈ -0.02 to -0.03). Agreeableness and openness showed weaker, less consistent associations, suggesting a genuinely bidirectional but modest relationship between loneliness and specific personality traits.
Zavhorodnia and Shepelova (2026) studied 147 Ukrainian university students (mean age 24, 78% women) during wartime martial law. Emotional stability was the strongest protective factor for subjective well-being, followed by openness, extraversion, and conscientiousness. Agreeableness unexpectedly predicted well-being decline, likely reflecting emotional exhaustion from caregiving demands in a predominantly female sample. Openness mediated effects of extraversion and novelty tolerance, and emotional stability moderated openness's protective role.
