The article reviews the factors contributing to Facebook use, proposing a dual-factor model based on psychological needs: the need to belong and the need for self-presentation. Demographic and cultural factors influence the need to belong, while personality traits like neuroticism, narcissism, shyness, self-esteem, and self-worth influence the need for self-presentation. Studies show that females and ethnic minorities use Facebook more frequently than males and Caucasians. Personality traits such as extraversion, neuroticism, and narcissism are linked to higher Facebook use. Research also indicates that Facebook use is associated with lower academic performance but may enhance self-esteem and a sense of belonging. Cultural differences affect Facebook use, with individualistic cultures more likely to share private information and discuss controversial topics, while collectivistic cultures may prioritize social connections and form closer friend groups. The need for self-presentation is evident in users' efforts to project idealized selves through their profiles. Overall, Facebook use is driven by social needs and personality traits, with cultural and demographic factors playing a significant role. Future research should explore cultural differences in Facebook use and its impact on self-esteem and social connections.The article reviews the factors contributing to Facebook use, proposing a dual-factor model based on psychological needs: the need to belong and the need for self-presentation.
