Regression analyses for drinking frequency outcomes

Variable		Estimate	SE	p
Outcome: Drinking days
Time 1 model
Overall mental health	MHI-5	-.06	.12	.636
	Perceived norms	.43	.26	.104
	MHI-5 × Perceived Norms	.00	.08	.995

	Perceived norms	.38	.27	.165
	MHI-5 × Perceived Norms	-.03	.08	.706
Outcome: Heavy drinking days
Time 1 model
Overall mental health	MHI-5	.07	.12	.545
	Perceived norms	.60	.25	.020
	MHI-5 × Perceived Norms	-.07	.08	.373
Time 2 model
Overall mental health	MHI-5	.04	.12	.705
	Perceived norms	.43	.25	.085
	MHI-5 × Perceived Norms	-.04	.07	.559

Notes: MHI-5 = Mental Health Inventory score. SE = standard error. Significant effect is bolded. We did not run follow-up tests for the number of drinking days or the number of heavy drinking days because interactions between the full MHI-5 composite score and the perceived norms interaction terms were nonsignificant for either outcome variable.
