Abstract-In this research we examined the social network use, and more precisely, the use of Facebook, and the impact on psychological factors such as self esteem and overall self perception. The participants were 87 teen athletes from sports such as basketball, volleyball and football. Results indicated that self esteem played a major role in the behaviour of children. Six Facebook factors were analysed: behavioral intention, satisfaction, using applications, time waste, social connection and social surfing. Finally the research pointed out where is the connection between social surfing, using applications, self esteem, self perception of athletic ability and self perception of physical appearance.
