Results: The majority of studies linked social media use to adverse mental health outcomes, particularly depression and anxiety. However, the relationship was complex, with evidence suggesting that problematic use and passive consumption of social media were most strongly associated with adverse effects. In contrast, some studies highlighted positive aspects, including enhanced social support and reduced isolation. The mental health impact of social media use, specifically during the COVID-19 pandemic, was mixed, with the full range of neutral, negative, and positive effects reported.
