Two hundred-ten patients will be randomly assigned to either CBT, TCC, or a control group. The CBT intervention will have three phases: 1) education on the nature of the adjustment process in chronic illness, 2) coping skill development, and 3) generalization and application of skills to everyday situations. Participants in the CBT group will attend 12 weekly group sessions of about 2 hours each. Participants in the TCC group will learn to perform 18 movements under the guidance of an expert TCC teacher. TCC participants will have 50 to 60 minute biweekly sessions during the 12-week study. Control group participants will attend weekly group educational sessions; these sessions will provide general knowledge about arthritis health and illness, and will include lectures, demonstrations, and question-and-answer sessions with experts in rheumatology, sleep science, and behavioral medicine.
