The main purpose of this study is to examine differences in quality of life and psychological distress for both Multiple Myeloma patients receiving treatment and their caregivers and to assess patient and caregiver prognostic understanding (understanding of the likely course of a disease over time) of Multiple Myeloma to guide development of more personalized treatment plans. This study looks to further understand quality of life changes throughout multiple myeloma therapy for both patients and caregivers to help determine ways to improve patient and caregiver understanding of illness and in turn, tailor customized treatment that best aligns with patient preferences. The study will use a series of questionnaires to measure quality of life, mood, coping strategies, and prognostic understanding.
