Brief Summary

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.

Detailed Description

This randomized controlled trial will explore the effects of an HRV biofeedback (HRVB) training session with a modified waitlist control in a population of Hematopoietic cell transplantation (HCT) patients. We will secondarily explore effects of a brief storytelling intervention, with or without the prior HRVB training. Two group of 10 HCT patients over the age of 18 will be recruited and enrolled into the study. The time of participating in this study will be 2-week proposed activities from the time of enrollment to completion. Specific participation will include baseline data collection (about 30 minutes), HRVB training session (30 minutes), watching and discussing stories (15 min for each week= 30 minutes) and one final data collection (about 30 minutes) at the end. For HRVB group, participants will be instructed to practice their HRV biofeedback skills at home for 10 minutes each day for a two-week period (about 140 minutes). Lab visit is required only twice for baseline data collection and final data collection. Other works will be via internet.

Primary Outcome Measures

Name	Time	Method
Changes from Baseline Heart Rate Variability (HRV and coherence scores) at 2 weeks	Baseline (T1), 2 weeks after (T2)	The Emwave Pro Plus device from HeartMath will be used to collect HRV data and heart rate using a 3-minutes "neutral" protocol (we call "waiting at the bus stop" implying that no particular intent for breath or mindful state is to be evoked) to understand the benefits of DS+ HRVB. In addition, HRV measures will be obtained for the 1-minute paced breathing period to understand the effects of paced breathing on HRV. The following precautions will be provided as instructions to participants prior to data collection: no coffee, tea, or caffeinated drinks such as energizing drinks in the 2 hours before the data collection, and no alcohol consumption during 24 hours prior to the data collection.

Secondary Outcome Measures

Name	Time	Method
Changes from Baseline Profile of Mood States (POMS) short version (Psychological Distress) at 2 weeks	Baseline (T1), 2 weeks after (T2)	Psychological distress will be measured using the Profile of Mood States (POMS) short version (15 items, 5-point Likert scale; 0=not at all, 4=extremely). The POMS is one of the most frequently used and validated scales in studies of psychosocial interventions for cancer patients. The POMS Total Mood Disturbance (TMD) score has been shown to be most sensitive to interventions designed to facilitate emotional expression. The POMS consists of the TMD dimensions (tension-anxiety; depression-dejection; anger-hostility; and confusion-bewilderment) (Cronbach's a = .93) to be used in the current study as the primary outcome measure; and two others (fatigue-inertia; vigor-activity) will be documented. Total of Mood Disturbance= (anxious+depression+anger+fatigue)- vigor (Range from 12 to 48). The higher values represent a worse emotional well-being.
