According to the data of China Internet Network Information Center, the number of mobile
Internet users in China has reached 11.67 billion, and the proportion of users using mobile phones to
access the Internet reached 99.7% by September 2021. When mobile phone or social software cannot be
used, negative emotions (e. g: anxiety and uneasiness) are caused by fear of missing something important
that others are experiencing or doing, can be called fearing of missing out in social media. Studies have
found that there is a certain correlation between loneliness and social network abuse. For example,
individuals with high fear of missing out are more likely to form serious problematic social media use
behaviors. Many scholars study the relationship between loneliness and the use of social media in different
groups, such as higher vocational students, college students and the elderly, and find that the excessive use
of social media has a significant correlation or mediating effect on loneliness.
