Predictor Variable	Week 8 n = 318			Week 26 n = 315
	OR	95% CI	p	OR	95% CI	p
DS	1.34	(0.49, 3.64)	.56	0.32	(0.07, 1.59)	.16
MI	1.36	(0.56, 3.33)	.50	1.06	(0.40, 2.81)	.91
DS × MI	0.61	(0.15, 2.48)	.49	3.95	(0.62, 25.28)	.15

Note. OR = odds ratio; CI = confidence interval; DS = Depression Symptoms group; MI = Motivational Interviewing group. For DS reference group is the control (minimal depression symptoms). For MI reference group is SC (standard care). All models controlled for age, gender, and income and ethnicity.
