A considerable body of research indicates that social support plays an integral role in determining students' successful adjustment to college. Unlike previous research that has evaluated face-to-face support interventions that occur during students' first semester at college, the current study reports on a student-centered social media site designed to enhance students' perceptions of social support prior to their arrival on campus. Results indicated that site usage increased students' perceptions that they would have a diverse social support network during their first semester at college, even when controlling for other potent predictors. The importance of social support perceptions for college adjustment is detailed and the ramifications of the social media intervention are discussed. (Contains 2 tables.)
