The relationship between social media use, stress symptoms and burden caused by coronavirus (Covid-19) in Germany and Italy: A cross-sectional and longitudinal investigation

Introduction: The need for “social distancing ”to reduce the spread of Covid-19 is accompanied by an increase of social media use (SMU). Many people engage in intensive online activity to find information about the current Covid-19 situation and to interact about it with other users. The present study investigated the extent of SMU as Covid-19 information source and its relationship with stress symptoms and burden caused by the pandemic in Germany and Italy. Methods: Cross-national longitudinal (Germany, N = 501; 3-months period) and cross-sectional (Italy, N = 951) data on Covid-19 information sources, stress symptoms and burden caused by Covid-19 were collected via online surveys. Results: About 50% of the German sample and about 60% of the Italian sample frequently used SM as Covid- 19 information source. Cross-sectional analyses in both countries revealed that SMU is positively associated with stress symptoms and experienced burden. Moreover, stress symptoms mediated the link between SMU and burden. This was also confirmed by longitudinal analyses in Germany (burden assessed three months after SMU and stress symptoms). Limitations: The mostly female and relatively young sample composition limits the generalizability of present findings. Only two European countries were investigated. Conclusions: The present findings reveal a potential negative impact of enhanced SMU on individual mental health state and behavior. Additionally, they emphasize the significance of a conscious and cautious use of SM as information source specifically during the pandemic
