The paper focuses on the question whether hope mediates the effect of personality traits on life satisfaction. It is based on the assumption that the cognitive ability to perceive the possibility of reaching one's own personal goals is an important outcome of personality traits as well as a strong predictor of life satisfaction. The research sample consisted of 451 secondary school and university students in Slovakia with mean age 20.02 years. Hope Scale (Snyder, 1995), Satisfaction with Life Scale (Diener et al., 1985), and NEO Five Factor Inventory (Costa, McCrae, 1992, Slovak version Ruisel, Halama, 2007) were used to measure the defined characteristics. The results showed that hope acts as a partial mediator between neuroticism, conscientiousness and life satisfaction, and a full mediator between extraversion and life satisfaction.
