Methods: Item selection was based on the pilot AAQ, prespecified conditions, the International Classification of Functioning, Disability, and Health core set for OA, existing measurement instruments, and focus groups of patients. Test-retest reliability was assessed in 30 of 110 patients. In 110 patients, correlations were calculated between the AAQ and the self-reported Hip Disability/Knee Injury and Osteoarthritis Outcome Score activities of daily living subscale (H/KOOS). In 45 of 110 patients, correlations with performance-based tests (stair climbing test, timed up and go test, and 30-second chair stand test) were calculated.
