This project will evaluate the effectiveness and general usefulness of two arthritis patient education programs. The first, the Arthritis Self-Management Program, is a 6-week, community-based program taught in small groups by peer leaders. The second, the Self-Managed Arthritis Relief Therapy (SMART) Program, is a computer-driven program delivered through the mail. Participants in this project are people with rheumatoid arthritis or osteoarthritis who are taking part in the larger long-term studies being conducted by ARAMIS (the Arthritis, Rheumatism and Aging Medical Information System).
