The goal of the paper was exploration of relations between excessive internet use and a set of sociodemographic factors, life satisfaction and personality traits. For that purpose a sample of 186 internet users was asked to complete the Big Five Inventory (BFI), the Life Satisfaction Scale and the Internet Addiction Scale, as well as a questionnaire used to assess a set of sociodemographic variables. The results showed that males with a secondary education, who are unemployed and not married are more prone to excessive use of internet when compared to other participants. Excessive internet use was found to be related with several of the Big Five personality traits, but when independent contributions to the prediction of the phenomenon are considered, the only statistically significant predictor of the examined personality traits was Consciousness. This trait also has the single greatest correlation with excessive internet use of the five considered personality traits. Relative to life satisfaction, the results showed that the relation of this construct to excessive internet use is not a direct one, but that it is mediated by Consciousness.
