Descriptive statistics (means, standard deviations) of external validators by DSM-V AUD severity qualifiers

DSM-V Qualifier Group	Overall	No/Minimal (1)	Moderate (2)	Severe (3)

	N = 396	N = 198 (50%)	N = 145 (36.16%)	N = 53 (13.38%)

External validator variables	Mean (SD)	Mean (SD)	Mean (SD)	Mean (SD)
Frequency of Alcohol Use Index	8.46(2.21)	7.67(2.21)	9.01(1.81)	9.96(2.03)^*
Quantity of Alcohol Use Index	7.81(2.24)	6.91(2.01)	8.32(1.84)	9.72(2.44)^*
CAPS-r sum scores	2.42(1.96)	1.52(1.46)	2.84(1.79)	4.69(1.78)^*
Govern (TRI)	6.57(4.52)	4.72(2.86)	7.42(4.24)	11.21(6.09)^*
Emotion (TRI)	7.06(4.25)	5.75(3.26)	7.44(3.85)	10.91(5.84)^*
Preoccupation (TRI)	4.48(2.85)	3.63(1.65)	4.79(2.99)	6.74(4.24)^*

Note: In order to improve the distributional characteristics of certain variables, the three TRI factors required square root transformations.

All MANOVA post-hoc group differences (3) > (2) > (1) are statistically significant at p < 0.01.
