The goal of this project is to conduct a pilot randomized clinical trial (RCT) to evaluate the feasibility of a brief, behavioral intervention to improve recovery following hematopoietic stem cell transplantation (HSCT). Cancer patients who were treated with HSCT will learn behavioral techniques to improve sleep and increase daytime activity with the goal of alleviating insomnia, fatigue, and depression. If the intervention demonstrates evidence of feasibility and acceptability, a future study will test the effects in a larger trial, with the long-term goal of improving the care and quality of life of cancer survivors recovering from HSCT.
