Comparing Approaches to Link SF-36 PF-10 Scores to PROMIS Physical Function: A Validation Study in Three Clinical Samples.

ABSTRACT:

Background

Physical function (PF) is a central patient-reported outcome (PRO) in many clinical conditions. However, the variety of existing PRO measures (PROMs) yield scores on different scales, limiting the score comparability and interpretability. To overcome this gap, the Patient-Reported Outcomes Measurement Information System (PROMIS®) established a standardized T-score metric using item response theory (IRT). As such, different PROMs measuring PF can be linked to this common metric, allowing for efficient harmonization of scores. Linking algorithms allow conversion of SF-36 PF-10 scores to the PROMIS-PF metric, but these methods have not been validated in independent clinical samples.

Objective

To validate and compare two established linking methods for the translation
