Description
Kinza Degerlund-Maldi and co-authors check, in 2026, whether a standard health survey measures life quality well in psoriatic arthritis. Swedish register data held 13,105 patients with the joint and skin illness. The survey, EQ-5D-3L, and its single health scale were set against other measures. Tests covered group gaps, shared movement, and response to change.
Both tools matched partner measures fairly to strongly and split groups as expected. Most validity guesses held up. Change tracking fared worse: many response guesses failed, and the health scale missed who improved. Gains outside pain may slip past the survey, the authors note. Trial teams should pair it with wider tools.
