This clinical trial tests a mindfulness intervention, consisting of group sessions and an individual session, using mindfulness based stress reduction techniques, to reduce patient reported symptoms for patients with chronic graft versus host disease (cGVHD). In patients undergoing allogeneic stem cell transplant, sometimes the transplanted cells from a donor can attack the body's normal cells (called graft-versus-host disease). In cGVHD patients may encounter stiffness, itching, joint and muscle pain, oral cavity pain, itchy eyes, shortness of breath, depression, anxiety, and poor sleep resulting in a significant impact on patients' quality of life. Mindfulness interventions use meditation practices with elements of psychology to improve emotional regulation, resilience and acceptance based coping. This mindfulness based intervention may reduce patient reported symptoms in patients with cGVHD.
