The longitudinal mediating role of sleep in associations between COVID‐19 stressors predicting mental and physical health outcomes among emerging adult college students.

The current study tested a longitudinal mediation model throughout the COVID‐19 pandemic focused on whether students' housing instability stress and food/financial instability stress at the beginning of the pandemic in spring 2020 (T1) informed sleep dissatisfaction and duration in fall 2020 (T2) and, in turn, physical and mental health in spring 2021 (T3). Further, we tested whether relations varied based on students' ethnic‐racial backgrounds. Participants included 879 Asian, Black, Latine, Multiracial, and White emerging adult college students (Mage = 19.95, SD = 0.33) from a large public university in the mid‐Atlantic region of the United States who attended college during the COVID‐19 pandemic and completed surveys about their experiences. Findings indicated a significant mediation process, such that T1 housing instability stress predicted greater T2 sleep dissatisfaction and, in turn, less physical health, greater depressive symptoms, and greater anxiety symptoms at T3. Additionally, T1 food/financial instability stress was significantly associated with less T2 sleep duration but was not, in turn, associated with any T3 outcomes. Findings did not vary by students' ethnicity/race. Results highlight that sleep dissatisfaction is an important factor that accounts for relations between COVID‐19 stressors predicting mental and physical health outcomes throughout the pandemic.
