RecruitingBehavioural interventionPRO and Wearable Data Insights From Individuals With R/R Multiple MyelomaThis study will evaluate the feasibility of a digital health coaching program for adults with relapsed or refractory multiple myeloma (R/R MM). One hundred adults with R/R MM will be enrolled at The University of Washington. Individuals who agree to take part in the study and sign an informed consent will be enrolled in a 3-month digital health coaching program. The program will provide weekly phone calls plus the delivery of learning materials to text or email. Questionnaires and data from a wrist-worn activity tracker will be collected. Outcomes include treatment and symptom experience, quality of life, financial burden, and how confident people feel to manage their health. Information about your condition and treatment will be collected, along with how often you use services like the emergency room, for care. This data will provide a better understanding of how a person experiences their R/R MM.
