This article reviews the literature on factors contributing to Facebook usage and proposes a model to explain these motivations. The authors suggest that Facebook use is primarily driven by two primary needs: the need to belong and the need for self-presentation. Demographic and cultural factors contribute to the need to belong, while personality traits such as neuroticism, narcissism, shyness, self-esteem, and self-worth contribute to the need for self-presentation. The review examines the technical features of Facebook, demographic characteristics of users, and the impact of Facebook use on personality traits. It also discusses the role of Facebook in identity construction and self-presentation. The authors conclude by identifying areas for future research, including the differences in Facebook use between individualistic and collectivistic cultures.This article reviews the literature on factors contributing to Facebook usage and proposes a model to explain these motivations.
