 Study Aims: This project has three specific aims: 1. Engage African American patients with OA, their support partners, health care providers, clinic administrators, and public health representatives in a process of evaluating and enhancing a pain CST program for culturally appropriate content and dissemination potential. 2. Examine the effectiveness of a 12-session, culturally enhanced, telephone-based pain CST program among African Americans with hip or knee OA. 3. Examine whether individual patient characteristics are associated with different levels of improvement in the CST program. The long-term objective of this research is to develop and disseminate an evidence-based pain CST intervention among African Americans with OA, to reduce disparities in outcomes.
