Test characteristics of shorter versions of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) for brief screening for problematic substance use in a population sample from Israel

Table 2 Performance of ASSIST-FC and ASSIST-Lite scores, for identifying problematic use^a

	Main analysis		Additional analyses with craving
	ASSIST-Lite	ASSIST-FC	ASSIST-FCr	ASSIST-FCCr
Substance	Area under the curve (AUC) (95% confidence interval)
Tobacco	0.86 (0.84, 0.88)	0.96 (0.95, 0.97)^b	0.92 (0.91, 0.93)	0.96 (0.95, 0.97)
Alcohol	0.77 (0.74, 0.80)	0.86 (0.84, 0.89)^b	0.85 (0.83, 0.87)	0.92 (0.91, 0.94)^c
Cannabis	0.89 (0.86, 0.91)	0.94 (0.92, 0.95)^b	0.94 (0.92, 0.96)	0.99 (0.98, 0.99)^c
Cannabis (8 + threshold)	0.91 (0.89, 0.932)	0.94 (0.925, 0.96)	0.95 (0.94, 0.97)	0.98 (0.97, 0.99)^c
Sedatives	0.89 (0.85, 0.94)	0.95 (0.92, 0.975)	0.96 (0.923, 0.94)	0.99 (0.977, 1.00)^c
Prescription stimulants	0.87 (0.82, 0.92)	0.94 (0.91, 0.962)	0.91 (0.86, 0.95)	0.98 (0.963, 0.99)^c
Prescription painkillers	0.84 (0.77, 0.90)	0.92 (0.88, 0.96)	0.90 (0.85, 0.96)	0.97 (0.95, 1.00)

FC = frequency and concern; FCr = frequency and craving; FCCr = frequency, concern, and craving
a ASSIST 3.1 moderate or high risk levels
Area under the curve (AUC) differ significantly where the 95% confidence intervals do not overlap: ^bASSIST-FC scores showed significantly higher AUC than ASSIST-Lite scores; ^cASSIST-FCCr scores showed significantly higher AUC than ASSIST-FC scores
