A study conducted by an online therapy directory service finds a majority of Americans — 58% — say they have experienced negative mental health effects from using social media, reports Media Daily News.

The study from OnlineTherapy.com, which is based on a survey of 1,250 U.S. adults conducted via Pollfish on October 7, found only 25% said their mental health has not been negatively affected, while 10% said they were unsure and 7% said they don’t use social media at all.

According to the report, anxiety was the leading side effect of social media use, with 64% of those negatively affected. Other side effects included depression (56%), dissatisfaction with life (52%), fear of missing out (52%), and body-image issues (51%).

More negative feelings correlated to more time spent on social media.
