The newly developed BC PROM was reliable and valid for assessing perceived balance confidence. In addition, the BC PROM offers efficient administration modes with low patient response burden, enhancing feasibility and use during routine clinical practice in busy rehabilitation settings. This study supports a transition to patient-reported outcome measures (PROMs) that are based on modern measurement approaches to achieve the combined benefits of high accuracy and efficiency.

Learning Objectives:

Understand the basic psychometric requirements of an IRT-based patient-reported outcome measure (PROM).
Understand the psychometric evidence (reliability, validity, and efficiency) for PROMs.
Learn how different administration modes (CAT, full and short forms) of the Balance Confidence PROM can be applied for various clinical and research applications.
