“…Loneliness is a subjective feeling of isolation, included in social networks and could affect the individual's well-being (Kong & You, 2013). Previous literature has well established the associations between social anxiety, loneliness, and life satisfaction (e.g., Brunes, Hansen, & Heir, 2019;Kong & You, 2013;Ren, Yang, & Liu, 2017;Tian et al, 2018). For example, Selecting 432 left-behind middle children from two rural middle schools, Ren et al (2017) and his collegues found that loneliness was positively associated with anxiety, and further played a mediating role between social anxiety and Internet addiction.…”
