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.
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.
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.
