Baseline McNemar Results: Specificity and Sensitivity Using Conventional and Robust Norms for Diagnostically NL Groups

		Sensitivity
	Specificity	NL→DEC
	HT	NL→DEC	→	Early	Late
Working Memory
Conventional	91%	8%	→	7%	9%
Robust	91%	18%	→	22%	14%
Immediate Memory
Conventional	94%	17%	→	22%*	12%
Robust	94%	13%	→	24%*	2%
Delayed Memory
Conventional	93%	10%	→	15%	5%
Robust	93%	20%*+	→	32%*+	9%
Attention-Language
Conventional	94%	7%	→	7%	7%
Robust	94%	18%*+	→	17%	19%

Note. HT = healthy test group; NL→DEC = normal decline group; early = normal baseline evaluation with early decline to mild cognitive impairment or Alzheimer’s disease (less than 5 years after baseline); late = normal baseline evaluation with late decline to mild cognitive impairment or Alzheimer’s disease (5 years or more after baseline).

⁺Significantly different from Sensitivity using Conventional norms within group, p < .05.

^*Significantly higher proportion impaired than HT group, p < .01.
