Summary of Intercorrelations, Means, and Dispersion for Age, Comorbidities, and Scores on the SPPB, MMSE, GDS, and PASE at Baseline and 12 months.

Measure	1	2	3	4	5	6	M	SD	Range
1. Age, baseline	—						85.0	7.5	64–96
2. Co-morbidities	.01	—					1.66	.91	0–4
3. SPPB, baseline	−.02	−.08	—				6.18	3.2	1–11
4. MMSE, 12 month	−.20	.00	.09	—			26.45	4.3	15–30
5. GDS^a	.20	−.19	−.28	.04	—		3.08	3.1	0–12
6. PASE	−.07	−.19	.39^*	.16	−.43^*		42.62	38.4	0–159
7. SPPB 12 month	−.05	−.06	.81^***	.16	−.32	.52^**	5.71	3.1	0–12

Note. For all scales, higher scores are indicative of more extreme responses in the direction of each construct. SPPB = Short Physical Performance Battery; MMSE = Mini Mental State Examination; GDS = Geriatric Depression Scale; PASE = Physical Activity Scale for the Elderly.
