Comparative Study
Multiple psychological factors are associated with poorer functioning in a sample of community-dwelling knee osteoarthritis patients.
Knee osteoarthritis (OA) is the most common type of arthritis and imposes a heavy burden on individual welfare among elderly people. There is preliminary evidence that psychological factors play a role in functional ability and pain in knee OA patients, particularly with respect to the surgery outcome. Less is known about psychological factors among community-dwelling patients with knee OA. ⋯ The results reveal that both pain self-efficacy and negatively charged emotion and expectations toward pain are important factors when dealing with knee OA patients. Failure to consider these will probably contribute to prolonged disability and further pain. The results call for the routine assessment of multiple psychological factors in knee OA.

Obese rheumatoid arthritis (RA) patients have higher levels of pain, disability, and disease activity than do nonobese patients with RA. Patients' health-related thoughts about arthritis and weight may be important to consider in obese patients with RA who face the dual challenge of managing RA and weight. ⋯ Pain catastrophizing, self-efficacy for arthritis, and self-efficacy for weight management each contributed uniquely to relate to key outcomes in obese patients with RA. Clinicians should consider assessment of thought processes when assessing and intervening with patients who face dual health challenges; unique intervention approaches may be needed for addressing the challenges of arthritis and weight.
