Due to its popularity and general pervasiveness in everyday life, in Serbia and in the entire world, FB has become a significant factor that influences our psychological and social functioning. The aim of this study was the construction and validation of the new questionnaire for measuring psycho-social aspects of FB use. Specifically, we wanted to create a new questionnaire, explore its latent structure, and to examine to which extent are FB-related experiences determined by users' personality. Regarding the relations between psycho-social aspects of FB use and personality traits, we started with two alternative presumptions. On one hand, FB behaviors can be understood as manifestations of established personality traits in a specific virtual surrounding, which could lead to moderate correlations between the two. On the other hand, virtual surrounding of FB offers possibility for identity exploration and experimentation (Valkenburg, Schouten, & Peter, 2005), where users can be what they are not in the “real” world. In such a case, users' behaviors and experiences on FB would not be influenced by their personality traits to a great extent, which might lead to low to insignificant relations between these constructs.
