Information quality, media richness, and negative coping: A daily research during the COVID-19 pandemic.

For most mobile technology users, social media platforms are their main source of information about the COVID-19 pandemic. Using the stimulus-organism-response model, this study proposes that information quality and media richness are related to social media fatigue, which induces negative coping with the COVID-19 pandemic. The moderating roles of health consciousness and COVID-19-induced strain are also examined. The data were collected from 108 users of WeChat using a daily experience sampling method and analyzed using multilevel structural equation modeling with Mplus. The results show that information quality significantly decreases social media fatigue, whereas media richness significantly increases social media fatigue, which is an outcome of negative coping. Health consciousness buffers the indirect effect of information quality on negative coping through social media fatigue, whereas COVID-19-induced strain strengthens the indirect effect of media richness on negative coping through social media fatigue. These findings enrich the literature on social media fatigue and negative coping by revealing the informational and technical causes of these issues at the episode level in the period of the COVID-19 pandemic.
