The study by Kross et al. (2013) investigates the impact of Facebook usage on subjective well-being in young adults. Using experience-sampling, the researchers text-messaged participants five times a day over two weeks to measure their Facebook usage and well-being. The results indicate that increased Facebook usage is associated with negative shifts in both moment-to-moment feelings and life satisfaction over time. Specifically, the more people used Facebook, the worse they felt and the less satisfied they were with their lives. This effect was not moderated by other factors such as the size of Facebook networks, perceived supportiveness, motivation for using Facebook, gender, loneliness, self-esteem, or depression. The study suggests that while Facebook provides a valuable resource for social connection, it may undermine well-being rather than enhance it. The findings have implications for understanding the relationship between technology use and mental health, particularly in the context of social media platforms.The study by Kross et al.
