A longitudinal study of 1,966 U.S. adults found no credible evidence that changes in social media usage frequency predict subsequent shifts in life satisfaction.
Key facts
- •The study analyzed data from 1,966 U.S. adults across five survey rounds.
- •Researchers tracked 10 platforms, including TikTok, Instagram, and WhatsApp.
- •No credible evidence was found that changes in social media use predict life satisfaction.
- •The study used a Bayesian statistical approach to analyze potential causal relationships.
- •Findings suggest that higher life satisfaction may modestly predict increased video calling usage.
Researchers from Georgetown University, USC, and UC Berkeley conducted a five-wave study to determine how social technology usage impacts the life satisfaction of adults in the United States. The findings, published in Nature Human Behaviour, indicate that changes in the frequency of using 10 common platforms do not predict subsequent changes in life satisfaction. The study utilized a Bayesian statistical approach to distinguish real effects from statistical noise across various demographic groups.

Study Methodology and Scope
The research team surveyed 1,966 adults over five rounds, with each survey conducted three months apart. Participants were recruited through the Understanding America Study, a project managed by USC. Researchers tracked usage of 10 specific technologies: FaceTime, texting, WhatsApp, email, Facebook, Instagram, Snapchat, X, TikTok, and YouTube. Life satisfaction was measured using a standardized three-item scale.
Findings on Usage and Satisfaction
The study found no credible evidence that increased or decreased use of these platforms predicted changes in life satisfaction three months later. This result remained consistent across all demographic subgroups, including variations in age, gender, race, education, and income. While the team observed that individuals with higher life satisfaction reported modest increases in video calling, they found no evidence that social technology makes adults either more or less satisfied with their lives.
Future Research Directions
The researchers noted that their findings are limited to adults and do not apply to children or adolescents. Future work aims to incorporate objective, device-level data to overcome the limitations of self-reported usage metrics. Additionally, a new study is underway involving adolescents receiving their first smartphones to examine the effects of social media access in a controlled, randomized setting.
