Prior research has shown that the use of social media may detract from face-to-face relationships, reduce investment in meaningful activities, increase sedentary behavior by encouraging more screen time, lead to internet addiction, and erode self-esteem through unfavorable social comparison. Self-comparison can be a strong influence on human behavior, and because people tend to display the most positive aspects of their lives on social media, it is possible for an individual to believe that their own life compares negatively to what they see presented by others. But some skeptics have wondered if perhaps people with lower well-being are more likely to use social media, rather than social media causing lower well-being. Moreover, other studies have found that social media use has a positive impact on well-being through increased social support and reinforcement of real world relationships.
Overall, our results showed that, while real-world social networks were positively associated with overall well-being, the use of Facebook was negatively associated with overall well-being. These results were particularly strong for mental health; most measures of Facebook use in one year predicted a decrease in mental health in a later year. We found consistently that both liking others’ content and clicking links significantly predicted a subsequent reduction in self-reported physical health, mental health, and life satisfaction.
