Comparing the Patient-Reported Physical Function Outcome Measures in a Real-Life International Cohort of Patients With Psoriatic Arthritis.

ABSTRACT:

Objective

We evaluated the psychometric properties of 3 patient-reported outcome measures to assess the physical function in psoriatic arthritis (PsA).

Methods

Data were available for the Health Assessment Questionnaire disability index (HAQ DI), the 12-item Short Form instrument physical component summary (SF-12 PCS), and the Psoriatic Arthritis Impact of Disease instrument functional capacity score (PsAID-FC). Data came from a longitudinal study in 14 countries of consecutive adults with definite PsA with ≥2 years of duration. The score distribution, construct validity, responsiveness, and thresholds of meaning of the patient-reported outcome measures were evaluated.

Results

At baseline, 414 subjects (52% male) were analyzed. The mean ± SD age was 52.4 ± 12.5 years
