Twenty-two independent community dwelling older adults were tested using both the MTT and the BBS on the same day at a senior center.
Correlations between the BBS and the MTT ranged between −0.765 and −0.79. The results of the Guttman's scalability analysis were a plus percentage ratio of 0.75 and an index of reproducibility of 0.93. Scales with these values are regarded as having evidence of unidimensionality.
All of the MTT tests correlated with the BBS. In addition, the MTT was found to be unidimensional.
Although the MTT correlated with the BBS and was found to be a good cumulative measure, it would benefit from continued study to examine quantifiability, validity and reliability. With further refinement and study, the MTT may be useful at discriminating fallers from non-fallers in high functioning older adults.
