This study, led by Dr. Larry D. Anderson Jr. from UT Southwestern Medical Center, aims to understand better how multiple myeloma patients feel about receiving treatments under the skin (subQ) versus through the vein (IV), and how those preferences affect their quality of life and treatment choices. Adults (18+) with a multiple myeloma diagnosis can take a 15–25 minute survey (26–50 questions) covering their diagnosis, treatment experiences, and preferences between subQ and IV administration, along with basic demographic information. Your answers are anonymous, and your insights are truly appreciated! You can take the survey here: https://htree.org/subcutaneousintravenous
