The Original and Short Versions of the Activities-Specific Balance Confidence (ABC) Scale in Community-Dwelling Older Adults: Clinical Implications Based on Scale Agreement, Internal Consistencies, and Associations With Self-Rated Health.

Despite a high correlation between the ABC-16 and ABC-6, the 2 scales showed limited agreement and should not be considered interchangeable. Given that the ABC-16 takes longer to administer, does not relate to SRH as strongly, and could have redundant items, the ABC-6 may be preferable to the ABC-16 for balance confidence assessment in older adults living in cold weather, urban, or well-resourced areas.
