Nostalgic Social Media Use and Psychological Well-Being During the COVID-19 Pandemic

Abstract

Physical and social distancing practices mandated during the COVID-19 pandemic posed serious threats to mental health on a global scale. Drawing upon the literature on nostalgia as a coping resource and the psychological benefits of nostalgic media use, we investigated the relationship between nostalgic social media use and psychological well-being amid the COVID-19 pandemic, considering perceived self-continuity as a mediator. An online survey conducted with a U.S. sample in June 2021 (Study 1; N = 485) showed that nostalgic social media use was positively associated with greater perceived self-continuity, which, in turn, positively predicted emotional well-being. These findings were replicated and extended by a follow-up online survey conducted with a South Korean sample in October 2021 (Study 2; N = 1,510). In addition to replicating the mediation results from Study 1, Study 2 demonstrated that the mediation was significantly moderated by household type (single-person vs. multiperson household). Specifically, those living alone, compared to those living with one or more cohabitants, were more likely to benefit from nostalgic social media use, maintaining higher levels of life satisfaction amid the global health crisis. Implications of these findings are discussed.
