 Participants in this study will be randomly assigned to either take part in a 10-session CST program for chronic pain or receive usual care. Participants in the treatment program will attend sessions in their doctors offices. A nurse practitioner or registered nurse will meet with each participant for approximately 45 minutes each week to teach methods for management of pain associated with OA. Some of the strategies will include relaxation training, managing activity cycles, and changing thought patterns to reduce the negative effects of pain. Some sessions may be conducted on the phone rather than in person. All sessions will be tape-recorded for quality assurance purposes. Participants will be asked to practice coping skills between visits. At the end of the last visit, participants will spend an additional 60 minutes completing a booklet of questions about their health, pain levels, and response to the treatment program. Participants assigned to the usual care group will continue to see their healthcare providers as they normally would. They will not meet with the nurse or receive the CST. Assessments of pain, physical and psychological disability, self-efficacy, pain coping skills, and quality of life will be conducted for all participants pre-treatment, post-treatment, and at 6-month and 1-year follow-ups.
