DescriptionExposure to distressing news media can have negative effects on mental health. The widespread news coverage of the ongoing COVID-19 crisis may be deleterious for mental health, particularly among college students with limited access to social support and coping resources during social distancing. The current study examines the impact of daily exposure to news about COVID-19 on same-day and next-day mental health among college students in the first months of the pandemic. 128 college students completed daily smartphone-delivered surveys assessing frequency of exposure to news about the pandemic, worry and optimism specifically related to COVID-19, hopelessness, and general worry. Multilevel mediation models indicated that greater exposure to daily news about COVID-19 was associated with greater worry about the pandemic, which in turn was associated with higher levels of hopelessness and general worry in the same day. Effects persisted across the next day, with COVID-worry mediating the relationship between greater COVID news exposure and next-day general worry and hopelessness. Optimism about COVID-19 was not related to amount of pandemic-related news consumed, hopelessness, or general worry. This study demonstrates the mental health impact of daily exposure to news about COVID-19 and highlights how pandemic-related worry generalizes to same-day and next-day hopelessness and general worry.
