Health Related Quality of Life and Personality Characteristics for Aging Well: Evidence from the Sardinian Blue Zone
M. C. Fastame, Benedetta Brandas, Corinne Martis · International Journal of Applied Positive Psychology · July 2026

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.

Chronic stress is associated with differences in big five personality traits
J. Ahmed, D. Ahmed · Discover Public Health · June 2026

This narrative review of 31 studies finds that chronic stress is consistently associated with higher neuroticism and lower levels of the remaining four Big Five traits. The neuroticism link is the strongest and most well-replicated; evidence for reduced conscientiousness is moderate; associations with extraversion, agreeableness, and openness are meaningful but largely cross-sectional. The relationship is likely bidirectional, and social support, coping strategies, and socioeconomic status all moderate these effects.

Personality and the Prediction of Consequential Outcomes
Ozer & Benet · Annual Review of Psychology · January 2006

The Big Five personality factors serve as powerful heuristics for predicting outcomes across multiple life domains. At the individual level, traits are linked to health, happiness, and identity. Interpersonally, they shape the quality of family and romantic relationships. Finally, at the institutional level, personality influences occupational success, political ideology, and community involvement. These findings underscore that personality dispositions are not just internal states but active drivers of significant life consequences.

Conscientiousness and Health-Related Behaviors: A Meta-Analysis of the Leading Behavioral Contributors to Mortality
Bogg & Roberts · Psychological Bulletin · January 2004

This meta-analysis explains why Conscientiousness is such a powerful predictor of a long life. By reviewing nearly 200 studies, researchers found that highly conscientious people consistently avoid risky behaviors (such as tobacco use, excessive drinking, and reckless driving) while actively engaging in beneficial habits like regular exercise and healthy eating. These findings demonstrate that personality doesn't just impact your mind; it physically protects your body by shaping your daily lifestyle choices.

Psychosocial and behavioral predictors of longevity: The aging and death of the 'Termites
Friedman et al. · American Psychologist · January 1995

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 divorce during childhood, serve as significant risk factors for premature death. These early-life stressors and traits also linked to unstable marriage patterns in adulthood, suggesting that long-term health is deeply influenced by the intersection of individual temperament and stable family environments.
