The Effect of Mobile Application-Based Education Developed According to Orem's Self-Care Model in Multiple Myeloma Patients

This randomized controlled trial aims to assess the effectiveness of a mobile application-based education program, developed according to Orem's Self-Care Model, in improving self-care agency and quality of life among patients with multiple myeloma in Turkey. Participants are recruited from the outpatient clinic of a hospital and randomly assigned to either the intervention or control group. The intervention group uses the mobile application for 24 weeks, while the control group continues with routine care and receives a standard one-page brochure commonly distributed to cancer patients. All participants complete a demographic form, the EORTC QLQ-C30, QLQ-MY20, and the Self-Care Agency Scale at baseline, week 12, and week 24. The collected data will be used to compare changes in self-care agency and quality of life between the two groups over time.
