Does Social Media Use Mitigate or Exacerbate Loneliness among Korean Older Adults? Focusing on the Moderating Role of Media Literacy

Abstract

As older adult populations rapidly increase worldwide, loneliness among older adults is emerging as a societal burden. Whether social media use can increase or decrease older adults’ loneliness remains debated in the literature. The purpose of this study is to clarify the effect of social media use on loneliness among older adults by examining the moderating role of media literacy on the relationship between social media use and loneliness. Considering that Korea is facing the most rapid population aging among Organisation for Economic Co-operation and Development (OECD) countries and that two-thirds of Korean older adults use social media, Korean data can provide international insights into the impact of social media use on older adults. Responses from 554 Korean respondents aged 60 to 79, extracted from the 2021 Korea Media Panel Survey, were analyzed using the PROCESS Macro Model 1. The results of this study showed that the effect of social media use on loneliness among older adults was moderated by their level of media literacy. As the amount of time spent using social media increased, loneliness increased for respondents with low-to-middle media literacy. This study’s findings emphasize the importance of educational interventions to increase older adults’ digital media literacy and expand scholarly understanding of the impact of social media use in non-Western countries.
