The aim of the current study was to investigate the relationship between Facebook intensity and social connectedness, self-efficacy and self-esteem. Participants were asked to complete a questionnaire that was comprised of four different scales measuring Facebook intensity, social connectedness, self-efficacy and self-esteem. Seventy-one participants took part in the study, of which 19 were male and 52 were female. The predictor variable was the subject’s score in the Facebook intensity scale, and the criterion variables were social connectedness, self-efficacy and self-esteem scores. The results reported that there was a significant relationship between social connectedness scores and Facebook intensity. It was noticed that a correlation between participants’ self-efficacy and self-esteem scores existed also. The difference between genders was approaching significance in the self-esteem variable. It was concluded that Facebook intensity increased social connectedness, but not necessarily self-efficacy and self-esteem.
