Construct Validity and Responsiveness of EQ-5D-3L and EQ-5D-5L in Patients With Inflammatory Joint Disease
Sponsor: Karolinska Institutet
Summary
The aim of this study is to compare the construct validity (convergent validity and known-groups validity) and responsiveness of EQ-5D-3L and EQ-5D-5L in patients with inflammatory joint disease. The study is based on prospectively collected data through the Swedish Rheumatology Quality Register (SRQ).

EQ-5D-5L
EQ-5D is a generic instrument used to measure, value, and compare health across symptoms and diagnoses. There are two versions of the EQ-5D, the EQ-5D-3L and the EQ-5D-5: Patients with inflammatory joint disease already complete patient-reported measures (PROMs), including EQ-5D-3L, routinely in conjunction with their follow-up healthcare visits, and patients who consent to participate in the study will also complete the EQ-5D-5L. The order in which the patient responds to the EQ-5D-3L and EQ-5D-5L is randomised so that participants answer one version of the EQ-5D before the other routinely collected PROMs, and the other EQ-5D version at the end. When data collection with EQ-5D-5L is concluded, all data necessary for analyses will be retrieved from the SRQ.
