Participant demographic and smoking characteristics by group

	Full sample (N = 162)	PTSD (n = 52)	MDD (n = 52)	Control (n = 58)
Women % (n) ac	6.4 (10)	15.7 (8)	1 (2)	1.8 (1)
White % (n)	70.4 (114)	71.2 (37)	76.9 (40)	63.8 (37)
High School Diploma/GED or less % (n)	35.9 (55)	28.8 (15)	35.3 (18)	41.5 (22)
Age (M, SD) b	52.43 (9.7)	49.4 (11.05)	54.98 (8.8)	52.89 (8.45)
FTCD (M, SD) a	5.7 (2.1)	6.3 (2.01)	5.8 (2.06)	5.05 (2.22)
Cigarettes/day (M, SD)	19.8 (8.4)	21.0 (6.94)	18.21 (8.61)	19.82 (9.50)

Note. Dummy coding was used to test for differences between the control group (reference group = 0) and both PTSD and MDD groups. Follow up tests compared PTSD vs. MDD groups. Significant group differences are identified with superscript letters. Superscript letters indicate significant group differences for specific contrasts noted below. Cigarettes per day data collection was added midway through the study and therefore reflect smaller sample size than other measures, PTSD (n = 39), MDD (n = 33), Control (n = 38). PTSD = posttraumatic stress disorder; MDD = major depressive disorder; FTND = Fagerström Test for Cigarette Dependence; GED = General Educational Development; M = mean; SD = standard deviation.

^ap < .05 for PTSD vs. Control

^bp < .05 for MDD vs. Control

^cp < .05 for PTSD vs. MDD
