Use of walking aids or support should be considered in ratings. Respondents are encouraged to ask questions if unclear, with contact information provided for assistance. This ensures accurate and reliable responses.
Scoring and Interpretation
The ABC Scale scores range from 0 to 100, calculated by averaging responses. Higher scores indicate greater confidence. Cut-off scores categorize functional levels, aiding clinical interpretation.
4.1 Calculation of Total Score
The total score is calculated by summing the ratings from all 16 items and dividing by 16. Each item is scored on a 0-100 scale, with higher scores indicating greater confidence. The total score ranges from 0 to 100, providing an overall measure of balance confidence. This method ensures consistency and reliability, allowing for easy interpretation of an individual’s balance abilities. The scoring process is straightforward, making it practical for both clinical and research applications.
4.2 Cut-Off Scores and Functional Levels
Specific cut-off scores on the ABC Scale help categorize individuals into functional levels. Scores below 50% suggest low balance confidence, while scores above 80% indicate high confidence. Myers et al. (1998) defined these thresholds to assess fall risk and functional mobility. Lower scores are associated with increased fall risk and limited activity participation. These cut-offs guide clinical interventions and rehabilitation strategies, helping to tailor care to individual needs and improve outcomes for those with balance impairments.
