Measurement of Minimal Disease Activity in Psoriatic Arthritis Using the Patient-Reported Outcomes Measurement Information System-Physical Function or the Health Assessment Questionnaire Disability Index.

ABSTRACT:

Objective

To assess the interchangeability of the Health Assessment Questionnaire disability index (HAQ DI) with the Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF) in the calculation of minimal disease activity (MDA) in psoriatic arthritis (PsA).

Methods

Comprehensive PsA disease activity was collected concomitantly with the HAQ DI and the PROMIS-PF measures in a PsA cohort. The PROMIS-PF-based MDA definitions were built using the existing cross-walk between the scores: HAQ DI ≤0.5 equivalent to a PROMIS-PF T score of ≥41.3. We assessed agreement between MDA (MDA HAQ DI) and the PROMIS-PF MDA definitions (MDA PROMIS-PF short form 4a and MDA PROMIS-PF bank) at each visit and longitudinally (MDA state changes between consecutive visits)
