Social media use, online experiences, and loneliness among young adults: A cohort study.

Résumé

This study investigated patterns of digital technology use and their associations with loneliness in a cohort of 1632 young adults (mean age 26) in the UK who had been followed prospectively since childhood by the Environmental Risk Longitudinal Twin Study. Data were collected via an online survey in 2019-2020. Although overall time spent online was associated with greater loneliness, this was not the case for social media usage specifically. Use of social media platforms (e.g., Facebook, Instagram, Twitter) showed no association with loneliness. Instead, greater loneliness was associated with the use of Reddit and dating apps, while the use of WhatsApp was associated with lower loneliness. However, individuals who reported more compulsive use of digital technology, or experiences of online victimization, were lonelier on average, suggesting that the types of experiences individuals encounter online may be more related to loneliness than using particular platforms per se. Associations were robust to controls for a prior history of depression or anxiety at age 18. Moreover, findings remained broadly consistent between those who participated before versus during COVID-19 lockdown measures. An exception was that certain types of media characterized by passive consumption were associated with loneliness prior to, but not during lockdown.
