A new 19-item scale effectively measures balance recovery confidence in older adults. This validated tool assesses perceived reactive balance, aiding in fall prevention strategies and enhancing confidence in managing balance challenges.
Area of Science:
- Gerontology
- Rehabilitation Science
- Biomedical Engineering
Background:
- Falls efficacy relates to an individual's perceived ability to prevent and manage falls.
- Existing instruments lack validation for measuring perceived ability to recover balance after destabilizing events.
Purpose of the Study:
- To develop and validate a scale measuring balance recovery confidence.
Main Methods:
- Candidate items generated via nominal group technique with older adults.
- Scale validation (name, instructions, items) using e-Delphi with experts and older adults.
- Psychometric properties evaluated in 84 older adults using classical test and Rasch measurement theories.
Main Results:
- A 19-item unidimensional scale was developed with expert consensus.
- Excellent internal structure (Cronbach's α = 0.975) and test-retest reliability (ICC = 0.944).
- Construct validity supported by correlations with established balance and function measures.
Conclusions:
- The Balance Recovery Confidence Scale is a distinct, psychometrically sound instrument.
- It measures perceived reactive balance recovery in older adults.
- The scale can complement other measures to help older adults manage balance challenges.
