Initial Validation of PROMIS Physical Function/Disability Scales in Rheumatoid Arthritis (RA)

The Patient-Reported Outcomes Measurement Information System (PROMIS) is an NIH Roadmap initiative to develop a computerized system measuring patient-reported outcomes in respondents with a wide range of chronic diseases and demographic characteristics. In the first four years of its existence, the PROMIS network developed item banks for measuring patient-reported outcomes in the areas of pain, fatigue, emotional distress, physical function, and social functioning. During the item banking process, the PROMIS network conducted focus groups, individual cognitive interviews, and lexile (reading level) analyses to refine the meaning, clarity, and literacy demands of all items. The item banks were administered to over 20,000 respondents and calibrated using models based on item response theory (IRT). Using these IRT calibrations, computerized adaptive test (CAT) algorithms were developed and implemented. The network has designed a series of studies using clinical populations to evaluate the item attributes, examine their utility as CATs, and validate the item banks. More information on the PROMIS network can be found at www.nihpromis.org.

About this study

This is a longitudinal clinical validation study of the PROMIS physical function, fatigue, and pain impact short forms in patients with rheumatoid arthritis (RA). Patients will complete assessments at two points: baseline and 6 months post-baseline. The responsiveness of six PROMIS static forms (physical function [HAQ, PF-10, 10 and 20 item short forms], fatigue, and pain impact) will be evaluated for change over the 6-month period. Physical function change scores will be contrasted with established Legacy physical function instruments. The test of "responsiveness" is defined as the ability of the instrument to detect change after major treatment intensification, self-reported improvement in functioning, or positive changes in patient global scores. The order of presentation of forms will be randomly assigned to eliminate questionnaire fatigue or other order effects as factors. We will also evaluate the test-retest reliability of four PROMIS static forms (HAQ and PF-10 physical function, fatigue, and pain impact) in a random subsample of patients at 1-week post-baseline. In addition, we will evaluate convergent validity of PROMIS measures of physical function by comparing self-report with observation of performance of physical function tasks in a subsample of patients randomly selected from the local geographic region.
