The sample consisted of 147 participants (51% female), aged between 20 and 35 years. Respondents completed the NEO-FFI Personality Inventory, Psychological Well-being Scale (PWBS), and Health Behaviour Inventory (IZZ). The results confirmed the significant relationships between the personality traits, health behaviors and psychological well-being. Extraversion, conscientiousness and neuroticism were related to health behaviors. Personality traits appeared as significant predictors of psychological well-being (68% of explained variances in PWBS). The health behaviors mediated the relationship between three abovementioned personality traits and psychological well-being. A higher health behavior score was shown to reduce the strength of the effect of personality traits on psychological well-being. Findings indicate that personality traits are important in designing health programs to improve mental health.
