This study is being performed to compare the effects of three types of group-based psychological treatments delivered over video telehealth for chronic musculoskeletal pain in older U.S. military Veterans. The three types of psychological treatments are: Cognitive-Behavioral Therapy (CBT), Emotional Awareness and Expression Therapy (EAET), and Mindfulness Meditation (MM). In addition, the investigators will evaluate which patients respond best to each treatment and how each treatment works. The investigators are performing the study because chronic pain is a big problem among Veterans. Older Veterans are the focus because they have the highest rates of chronic pain, perhaps as high has 80%. The investigators are looking at psychological treatments because they are less risky than medications or procedures for older Veterans. Telehealth is an important aspect of the proposal, as delivery over telehealth could improve access to treatments. CBT is endorsed nationally by VA, but no standardized MM is available through VA, and only a few VA sites use EAET, which is a newer treatment focusing on how stress and emotions affect pain. The project aims to evaluate a standardized form of MM and the newer treatment, EAET, compared to the standard CBT used widely in VA.
