This study included nearly 1,800 people aged 19 to 32 who completed an online questionnaire and found that those who used social media sites/apps more often—either in terms of the number of times they used them or in total amount of time spent on them—were more likely to feel isolated from others. Study lead author Dr. Brian Primack explains, “Compared with those in the lowest quarter for frequently checking social media, people in the top quarter were about three times as likely to have increased social isolation.”
