Hierarchical Step	Predictor Variable		Change Statistics
		Adjusted R²	Δ R²	Δ F	Sig. Δ F
1	ADL	.07	.08	5.93	.02
2	GDS	.16	.10	8.71	.004
3	FrSBe Total “Before”	.20	.05	4.41	.04
4	FrSBe Total “After”	.31	.12	12.54	<.001

Note. Total R² = .61, F(4, 71) = 9.77, p<.001; CDR = Clinical Dementia Rating Scale; GDS = Geriatric Depression Scale; FrSBE = Frontal Systems Behavior Scale (T scores).
