Abstract
OBJECTIVE: Develop and pilot test a mobile health (mHealth) cognitive behavioral coping skills training and activity coaching protocol (HCT Symptoms and Steps) for hematopoietic stem cell transplant (HCT) patients. DESIGN: Two-phase, mixed methods study. SAMPLE: HCT patients and healthcare providers. METHODS: Phase I was patient (n = 5) and provider (n = 1) focus groups and user testing (N = 5) to develop the HCT Symptoms and Steps protocol. Phase II was a pilot randomized trial (N = 40) to evaluate feasibility, acceptability, and pre-to-post outcomes (e.g., physical disability, pain, fatigue, distress, physical activity, symptom self-efficacy) compared to an education control. FINDINGS: Qualitative feedback on symptoms, recruitment strategies, coping skills, and mHealth components (e.g., Fitbit, mobile app) were integrated into the protocol. HCT Symptoms and Steps were feasible and acceptable. Pre-post changes suggest physical disability and activity improved while symptoms (e.g., fatigue, distress) decreased. CONCLUSIONS: HCT Symptoms and Steps have strong feasibility and acceptability and shows promise for benefits. Larger, fully-powered randomized trials are needed to examine intervention efficacy. IMPLICATIONS: HCT Symptoms and Steps may reduce physical disability and improve health outcomes post-transplant. CLINICAL TRIAL REGISTRATION NUMBER: NCT03859765.
