Bridging patient-reported outcomes and performance assessments in older adults: linking the Short Physical Performance Battery to the standardised PROMIS Physical Function scale

Key Points

• The Short Physical Performance Battery is connected to the PROMIS Physical Function T-score for standardized assessment.
• A user-friendly score cross-walk table enhances application in clinical practice and standardizes geriatric research.
• This connection enables meaningful aggregation of performance-based and self-reported physical function data.
• Such linkage may improve clinical outcomes by allowing more comprehensive evaluations of physical health.
