  ABSTRACT: Objective: The purpose of this study is to investigate whether the LE CAT, PROMIS PF CAT, Depression CAT, or Pain CAT can be used as a proxy for the EQ-5D-5L. Background: Patient-reported out-come measures have become vital tools for physicians to understand the effectiveness and value of treatment and care. Methods: This study was conducted in 2012 with 116 patients that took the EQ-5D-5L and a number of patient-reported outcome instruments in a university orthopaedic clinic. Regression analyses were conducted to predict EQ-5D-5L index scores from the LE CAT, PROMIS PF CAT, Depression CAT, and Pain CAT. Results: All predictors, separately or combined, significantly predicted the EQ-5D-5L index scores (p
