Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Patients undergoing hematopoietic stem cell transplantation (HCT) often continue to experience anxiety, depression, isolation, and other psychosocial distress due to the severe nature of the transplant experience. Storytelling interventions that provide an opportunity for emotional disclosure have shown preliminary efficacy to alleviate psychosocial distress and improve emotion regulation during health challenges. Not only are these changes observed in response to such interventions, but they can also be directly strengthened with HRV biofeedback (HRVB) training, a device-driven breath pacing practice that uses colored light signals to provide feedback to increase vagal tone and improve emotional responses and sleep quality by regulating negative affect and stress. This randomized controlled trial will explore the effects of HRV biofeedback (HRVB) training combined with a digital storytelling intervention and changes in psychosocial distress with a modified waitlist control in a population of Hematopoietic cell transplantation (HCT) patients.
