The vast majority of college-aged students use social networking sites (SNS) to foster connectedness and enable networking. In addition, SNS allow individuals to control their online self-presentation. This may lead to incongruence between students' actual selves and their curated online selves, thereby damaging one's self-perception by increasing social comparison orientation. The goal of this article was to investigate the relationship between SNS use and self-concept that has not yet been explored in depth among the postsecondary population. Utilizing Arksey and O'Malley's methodological framework, a scoping review of the published literature was conducted. A total of 41 articles were included in the review. Three overarching themes were extracted from the findings. The first theme found that consistent exposure to the thin ideal and fitspiration posts across various SNS were linked to increased body dissatisfaction. The second theme found that engaging in online academic or ability-based comparisons resulted in a worsened mental state among postsecondary students. The third theme found that one's SNS followers or the number of "likes" received have mixed effects on student self-concept. Through gaining an improved understanding of the SNS stressors that contribute to students' mental health from this review, postsecondary institutions can implement more targeted interventions to bolster student wellbeing.
