Osteoarthritis - Evidence
HAQ (health assessment questionnaire)
The Health Assessment Questionnaire (HAQ) was developed as a comprehensive measure of outcome in people with a wide variety of rheumatic diseases, including rheumatoid arthritis, osteoarthritis, juvenile rheumatoid arthritis, lupus, scleroderma, ankylosing spondylitis, fibromyalgia, and psoriatic arthritis. It has also been used in HIV/AIDS and in studies of normal ageing. It should be considered a generic instrument rather than a disease-specific one. Its focus is on self-reported patient-oriented outcome measures, rather than process measures [Fries, 2008].
