This thesis examines the relationship between personality and both mental and physical
health in older adults, combining a theoretical and empirical framework. The first part presents
the main theoretical approaches to personality, such as Freud’s psychodynamic perspective, the
trait theories of Allport and Cattell, and Eysenck’s three-dimensional model, with particular
emphasis on the Five-Factor Model (Big Five), which today represents the most widely used
framework for studying personality. Its core dimensions and assessment tools (NEO-PI-R, Big
Five Markers, BFI-10) are analyzed, along with their applications in psychological research and
health. The empirical part draws on data from the 9th wave of the SHARE study (2021), with
a sample of 65,598 individuals aged 50 and above from 27 European countries and Israel. The
associations of personality traits, measured with the BFI-10 scale, with indicators of mental
well-being, physical health, and socioeconomic parameters are examined. Results showed that
neuroticism consistently emerged as a strong negative predictor across all health outcomes,
while extraversion, conscientiousness, agreeableness, and openness were linked to more
favorable outcomes. Adding personality traits to the models significantly improved their
explanatory power, confirming that personality constitutes an independent and substantial
predictor of health in later life. In conclusion, the findings highlight the importance of
integrating personality assessment into research and clinical practice in order to enhance the
understanding of the factors that influence resilience and well-being in aging populations.
