Query: International students' loneliness, depression and stress levels in
  COVID-19 crisis. The role of social media and the host university   The move to university life is characterized by strong emotions, some of them
negative, such as loneliness, anxiety, and depression. These negative emotions
are strengthened due to the obligatory lockdown due to the COVID-19 pandemic.
Previous research indicates association among the use of social media,
university satisfaction, and the aforementioned emotions. We report findings
from 248 international undergraduates in The Netherlands, all students at the
International School of Business. Our results indicate strong correlations
between anxiety, loneliness, and COVID-19-related stress with university
satisfaction together with social capital. Keywords: COVID-19; Pandemic;
lockdown; loneliness; depression; anxiety; international students
