With the recent widespread use of social networking services (SNS), non-face-to-face communication has become increasingly common among younger generations, including university students. This study aimed to clarify the relation between university students’ face-to-face and non-face-to-face interactions and their subjective well-being. An online survey was conducted targeting university students nationwide, and the responses were analyzed based on three categories of interaction partners: close friends at the same university (n=340), classmates at the same university (n=347) and friends outside the university (n=353). The results indicated that both face-to-face communication and text-based non-face-to-face communication were primarily used with close friends and classmates at the same university, as well as with friends outside the university. Subjective well-being tended to be higher among students who interacted more frequently and tended to be lower lower among those who interacted less frequently. This relation was consistent for both face-to-face and text-based non-face-to-face communication. These findings suggest that text-based non-face-to-face communication may contribute to subjective well-being in a manner similar to face-to-face communication.
