Reliability, validity, and agreement of the short-form Activities-specific Balance Confidence Scale in people with lower extremity amputations.

Background: Clinicians use the Activities-specific Balance Confidence Scale to understand balance confidence. A short-form Activities-specific Balance Confidence scale, was developed using the six most difficult tasks from the original Activities-specific Balance Confidence scale; however, short-form the short-form scale psychometrics and agreement with the original scale have yet to be explored in people with lower extremity amputations.

Objective: To determine the relative and absolute reliability, construct validity, and agreement of the short-form Activities-specific Balance Confidence scale.
