Sleep Patterns and Affect Dynamics Among College Students During the COVID-19 Pandemic: Intensive Longitudinal Study

Specifically, the correlation between the COVID-19 worry mean and PA mean was −0.19 (P=.43), and the correlation between the COVID-19 worry mean and NA mean was 0.43 (P=.06). The multilevel models of the relation between sleep and affect revealed that participants with a higher SOL (b=−1.09, SE 0.36; P=.006) and TST on the prior day (b=−0.15, SE 0.05; P=.008) had lower PA on the next day, while controlling for previous-day PA. No within-subject differences were observed in predictions for next-day PA.

Using Multimodal Assessments to Capture Personalized Contexts of College Student Well-being in 2020: Case Study

For example, Lee’s positive and negative affect were positively correlated in April (eg, high positive and high negative affect; r=0.53, P=.04) whereas they were negatively correlated in September (eg, high positive and low negative affect; r=–0.57, P=.03). BPM and RMSSD were relatively correlated throughout each time point (Multimedia Appendix 1, Tables S1-S4).
