 Study Description: Following the incorporation of Stakeholder perspectives into the pain CST program, the investigators will conduct a randomized controlled trial. The investigators will enroll n248 African Americans with hip or knee OA. They will be randomized into two groups. One group will take part in a 2-week pain CST intervention. The other group will be a wait list that receives the pain CST program after completing all follow-up study measures. All study participants will be able to continue any other usual medical care for their OA during the study period. The pain CST intervention includes 12 individual sessions with a study counselor, delivered via telephone to enhance access and reach. The sessions include the following: general information about why pain coping skills training is important, training in specific pain coping skills such as progressive muscle relaxation, communication, imagery, and activity pacing, and guided practice with each skill. The CST program will also include information about other behaviors important for OA, such as physical activity and weight management. The main study outcome will be the pain subscale of the Western Ontario and McMasters Universities Osteoarthritis Index WOMAC. Other outcomes will include the WOMAC function subscale, Coping Strategies Questionnaire, Arthritis Self Efficacy Scale, depressive symptoms, Health-Related Quality of Life, and Patient Global Impression of Change. These measures were selected based on Stakeholder input and prior research that showed these outcomes are important to patients with OA. Statistical models will be used to compare outcomes between the two study groups at each time point: baseline, 12 weeks after completion of the initial CST intervention, and 36 weeks about 6 months after intervention completion. The investigators will also assess whether there are different levels of improvement in outcomes of the CST intervention, based on participant characteristics.
