The effects of pain on functioning and well-being were examined in 367 older adults with osteoarthritis (OA) of the knee. The relationship of OA-related pain to depressive symptoms and perceived health was hypothesized to be direct as well as mediated by physical and social functioning. Results showed that OA-related pain was related to poorer physical and social functioning, had a direct effect on depressive symptoms, and direct and indirect effects on perceived health. Lower social functioning was related to more depressive symptoms, and both lower social and physical functioning predicted worse perceived health. Thus, distinguishing between physical and social functioning when examining the costs of OA-related pain is useful. Moreover, existing pain-psychological well-being models can be generalized to perceived health.
