Multilevel Model Coefficients for NA, PA and PA/NA Ratio for 8h TIB compared to 6h TIB subgroups

	NA	PA	Positivity ratio (PA/NA)
	B (SE)	B (SE)	B (SE)
Level 2: Person-level
8h TIB (Reference)	–	–	–
6h TIB (Late Bedtime)	1.01 (1.26)	0.68 (1.24)	−0.04 (0.11)
6h TIB (Early Risetime)	−1.89 (1.25)	1.27 (1.23)	0.23 (0.11)^*
Level 1: Daily-level
Day	0.20 (0.10)^*	− 0.05 (0.08)	− 0.02 (0.008)^*
NA spillover	0.17 (0.03)^***	− 0.04 (0.03)	−0.01 (0.003)^***
PA spillover	− 0.03 (0.03)	0.17 (0.03)^***	0.01 (0.003)^***
Group x day
6h TIB (Late Bedtime) x day	− 0.32 (0.13)^*	0.03 (0.11)	0.03 (0.01)^**
6h TIB (Early Risetime) x day	− 0.14 (0.12)	0.02 (0.11)	0.01 (0.01)

Note. TIB indicates time in bed. NA indicates negative affect. PA indicates positive affect.
