Table 5.

Estimated proportion of change in one standard deviation of the commonality estimated from a structural equation model for the distinct outcomes of mobility disability.

Outcome	Variable (See Appendix)	Proportion Conveyed to Underlying Construct*	95% Credible Interval
400 meter walk	w1	−0.80	[−1.11, −0.56]
4 meter walk	m1	−0.22	[−0.32, −0.18]
SPPB	s1	0.32	[0.29, 0.34]
SRDS	d1	−0.13	[−0.15, −0.11]

^*Signs denote direction of the relationship. Results of 400 meter walk and 4 meter walk were coded as 1 = failure and 0 = success. Thus, higher scores for the walks and SRDS and lower scores for SPPB were associated with worse performance.
