Generalized mixed-effects hurdle models: Prospective associations between stress and substance use

		AUDIT		CUDIT
Predictor	Level	Any Alcohol Use (OR)^a	Alcohol Use Problems (RR)^b	Any Marijuana Use (OR)^a	Marijuana Use Problems (RR)^b
Internalized stigma	Within	.83	.98	.84	1.00
	Between	.97	1.12^*	.97	1.04
Microaggressions	Within	1.15	.99	.94	1.02
	Between	1.49^*	1.06^*	1.09	1.06
Victimization	Within	.85	1.07	1.19	1.04
	Between	1.31	1.02	1.15	1.15
General Stress	Within	1.00	.99	1.00	1.00
	Between	.98	1.01^*	1.01	1.01^*

All models were estimated controlling for linear change in likelihood of substance use and substance use problems over time, age at baseline, sexual identity, gender identity, race/ethnicity, and AUDIT or CUDIT score at baseline.

coefficient for hurdle portion of model (likelihood of using substance);

coefficient for count portion of model (count of substance use problems).
