Correlations among SCD Items Within and Across Cognitive Domains

Cognitive Domain		Memory			Concentration
	Reference Group	Same age (BAS)	Most others (GDS)	None (QOL)	Same age (BAS)
Memory	Most others (GDS)	0.26^(0.55 ^)
	None (QOL)	0.56^(0.44 ^)	0.36^(0.31^)
	Same age (OE)	0.44^(0.66 ^)	0.27^(0.32 ^)	0.45^(0.37 ^)
Concentration	None (GDS)		0.07		0.21^(0.33^)
Concentration	Same age (BAS)	0.67^(0.29^)
Word-Finding	Same age (BAS)	0.48^**(0.15)
Speech	Same age (BAS)	0.41^(0.01 ^)
Decision-Making	None (GDS)		0.23^**
Clarity of Mind	Previous Self (GDS)		0.18^*

Shaded results are within cognitive domains and across scales. Non-shaded results are across domains and within scales. Correlations are reported for the variables coded originally with correlations between the variables dichotomously coded in parentheses. GDS = Geriatric Depression Scale; BAS = Brief Anosognosia Scale; QOL = Quality of Life-AD; OE = Open-Ended question.

None = No reference group.
