Responsiveness and Minimum Clinically Important Difference in Patient-Reported Outcome Measures Among Patients With Psoriatic Arthritis: A Prospective Cohort Study.

ABSTRACT:

Objective

To determine the responsiveness to therapy and minimum clinically important improvement (MCII) for patient-reported outcome measures in psoriatic arthritis (PsA) and to examine the impact of baseline disease activity on the ability to demonstrate change.

Methods

A longitudinal cohort study was performed within the PsA Research Consortium. Patients completed several patient-reported outcomes, including the Routine Assessment of Patient Index Data, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Psoriatic Arthritis Impact of Disease 12-item (PsAID12) questionnaire, and others. The mean change in the scores between visits and standardized response means (SRMs) were calculated. The MCII was calculated as the mean change in score among patients who
