Logistic Regression Analyses Predicting Lifetime Stimulant Use Disorders From Depressed Mood and Anhedonia Among Respondents With Lifetime History of Stimulant Use

	Univariate		Combined^a
	Unadjusted		Unadjusted		Adjusted^b		Adjusted^c
Predictor	OR (95% CI)	p	OR (95% CI)	p	OR (95% CI)	p	OR (95% CI)	p
Outcome: Amphetamine dependence
Depressed mood	2.30 (1.71–3.10)	<.0001	1.20 (0.76–1.90)	.44	1.29 (0.80–2.08)	.30	1.15 (0.72–1.84)	.56

Outcome: Cocaine dependence
Depressed mood	2.30 (1.84–2.87)	<.0001	1.03 (0.73–1.48)	.84	1.11 (0.77–1.60)	.56	1.04 (0.72–1.50)	.76

Note. N = 1718 for amphetamine analyses; N = 2490 for cocaine analyses. OR = odds ratio; CI = confidence interval.

Models include anhedonia and depressed mood as simultaneous predictors.

Adjusted for demographics (age, region, ethnicity/race, marital status, sex, and education).

Adjusted for demographics and lifetime history of nondepressive psychiatric disorder, disorder, alcohol use disorder, nonstimulant drug use disorder, and nonstimulant drug use.
