The goal of this project is to refine and evaluate the feasibility of a brief, behavioral intervention to improve the 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 after HSCT. If the intervention is feasible and acceptable to patients, 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.
