Activities Specific Balance Confidence Scale
Also written as: ABC Scale — Activities-Specific Balance Confidence Scale
A self-report outcome measure that quantifies an individual's confidence in performing specific daily activities without losing balance or experiencing instability.
Full Definition
The Activities-Specific Balance Confidence (ABC) Scale is a 16-item self-report questionnaire in which participants rate their confidence in performing activities ranging from walking around the house to walking on icy pavements, each rated from 0% (no confidence) to 100% (complete confidence). It is widely used in rehabilitation outcomes measurement, particularly for fall-risk assessment in older adults and those with neurological or musculoskeletal conditions. Editors should note that the hyphen in 'Activities-Specific' is standard in the full title; the acronym ABC Scale is acceptable after first use. The scale is distinct from clinical balance performance tests such as the Berg Balance Scale, which observes performance rather than self-reported confidence.
Usage
Usage note: Retain the hyphen in 'Activities-Specific' in the full title. Use 'ABC Scale' as the short form after first expansion.
