Abstract
Methods
The EQ-5D and ICECAP-O were administered once at 12 months post first clinic attendance. We report descriptive statistics
for all baseline characteristics collected at first clinic visit and primary outcomes of interest. We ascertain feasibility
by reporting item completion rates for the EQ-5D and ICECAP-O. Contingency tables for a priori assertions between the ICECAP-O
and EQ-5D were used to demonstrate whether unique or similar aspects of benefit were captured. We used exploratory factor
analysis, to ascertain the number of unique underlying latent factors associated with the attributes assessed by the EQ-5D
and ICECAP-O.

Results
We report data on 215 seniors who attended the Vancouver Falls Prevention Clinic who had a mean age of 79.3 (6.2) years. The
item completion rate was 99 % for the EQ-5D and 92 % for the ICECAP-O. The two contingency tables detailed few discrepancies.
The results of the exploratory factor analysis indicate that the two instruments are tapping into distinct factors that are
complementary.
