Lagged analyses of social media use predicting momentary PA and NA at the next assessment.

PA		β (SE)	t-value	p
Step 1	Social media use	−.03 (.01)	−2.60	.009
Step 2	Social media use	−.03 (.01)	−2.63	.009
	Sex	−.15 (.06)	−2.52	.01

NA		β (SE)	t-value	p
Step 1	Social media use	−.02 (.01)	−1.49	.14
Step 2	Social media use	−.02 (.01)	−1.47	.14
	Sex	.01 (.06)	0.19	.85
	Depressive disorder	.28 (.06)	4.76	<.001
Step 3	SMU X Sex	.02 (.05)	0.35	.73
	SMU X Depressive disorder	−.04 (.02)	−2.39	.02

Note: N = 2,953 surveys nested within 138 participants. We reverted to a fixed slope for social media use. Interaction terms were tested in separate models to avoid overcontrolling. Sex and depressive disorder were retained as covariates when testing interaction terms. Biological sex was coded as 1 = male, 2 = female. Degrees of freedom are 2158 for social media use at Step 1 and 135 for between-person variables.
