Construct Validity and Responsiveness of EQ-5D-3L and EQ-5D-5L in Patients With Inflammatory Joint Disease

5 mei 2026 bijgewerkt door: Emelie Heintz, Karolinska Institutet
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).

Studie Bevolking

Patients with inflammatory joint disease complete PROMs routinely in conjunction with their follow-up healthcare visits, through an online platform called Patients Own Registration (PER). Patients who meet the inclusion criteria will be asked whether they want to participate in the study when they access PER.

Beschrijving

Inclusion Criteria:

  • Agreed to participate in the study
  • ≥18 years at the time of the first measurement
  • A diagnosis of rheumatoid arthritis (RA), polyarthritis, psoriatic arthritis (PsA), or ankylosing spondylitis (AS)
  • Complete registration of responses in the EQ-5D-3L and EQ-5D-5L descriptive system at least at one time point (one visit)
  • For patients with RA: At least one measurement with Disease Activity Score 28 (DAS28) reported in relation to the same visit as the EQ-5D was registered
  • For patients with polyarthritis: At least one measurement with DAS28 reported in relation to the same visit as the EQ-5D was registered
  • For patients with PsA: At least one measurement with DAS28 or Disease Activity in Psoriatic Arthritis (DAPSA) reported in relation to the same visit as the EQ-5D was registered
  • For patients with AS: At least one measurement with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) or the Axial Spondyloarthritis Disease Activity Score (ASDAS) reported in relation to the same visit as the EQ-5D was registered

Tijdsspanne
EQ-5D-3L
Tijdsspanne: Established disease: Baseline at inclusion in the study and the next health care visit within the study period (nov 23 - mar 26). Newly diagnosed disease: At baseline and at every health care visit throughout study completion (nov 23 - mar 26).
Instrument used to measure and value health-related quality of life. The instrument consists of five items/dimensions that can be answered from 1-3. A higher score indicates more problems. The responses to the items can be recalculated into an index value where 1 indicates full health and 0 a state considered equivalent to being dead.
Established disease: Baseline at inclusion in the study and the next health care visit within the study period (nov 23 - mar 26). Newly diagnosed disease: At baseline and at every health care visit throughout study completion (nov 23 - mar 26).
