Table 2. Control group vs. ADHD group for the PAI ADHD indicators and the CAARS-E scale.

Indicator	Group	M (SD)	d	AUC (SE)	Article Cut score	Sens. at cut	Spec. at cut
PAI-ADHD	Control	12.86 (6.50)	0.66	.677** (.042)	13	.755	.494
	ADHD	17.24 (7.19)
Inattention	Control	57.76 (13.94)	0.56	.642* (.042)	3 (77 T)	.204	.931
	ADHD	65.86 (17.18)
CAARS-E	Control	12.54 (6.67)	0.79	.703** (.040)	20	.347	.880
	ADHD	17.84 (7.08)

Note. **p < .001, *p < .01. The PAI-ADHD and the CAARS-E scale are expressed in raw scores. The cut score for the CAARS-E corresponds to 65 T for women aged 18–19. For the Inattention scale, we were able to convert the standard raw score into a T-score using the original community normative sample of the PAI. Thus, we present both a raw score and a T-score.

	ADHD	.500 (.273)

Note. All scores are presented as t-scores, with the exception of the two FAA scales. These scales both range from 0 to 1, with higher scores representing a higher likelihood of feigned ADHD.
