Exploring the effect of social media use on loneliness among older adults: A meta-analysis.

With the global aging population, more research is needed on older adults' mental health, particularly loneliness, a key psychological challenge resulting from life changes. While some researchers highlighted the potential of social media in reducing loneliness, the empirical findings remain unclear. This meta-analysis, including 19,134 observations, revealed no significant overall correlation between social media use and loneliness among older adults. To explore variability between studies, we conducted sensitivity analyses (excluding influential studies), subgroup analyses (based on age group, year of data collection, measure of social media use, and study region), and meta-regression with gender distribution as a moderator. Notably, a negative association was identified in the subgroup of studies conducted before COVID-19, indicating that social media may have helped reduce loneliness among older adults during that period. However, this benefit highlights that online networking cannot fully replace real-life social interaction.
