MMP includes three modules: addressing psychological problems such as FCR; addressing problems related to breast cancer symptoms; and addressing tangible problems such as social support. Each module is divided into the chemotherapy period (hospitalization) and the chemotherapy interval (post-discharge). Each phase involves face-to-face, digital, and remote tools, with the intervention lasting 8 weeks. Each module has a different goal, and depending on the goal setting, the topic of the intervention is different. The goal of the information education stage is to improve patients' overall understanding of the disease and pay attention to the psychological problems of FCR. The goal of coping skills is that through the practice of coping skills, patients can learn to change thoughts, problem emotions, and behaviors. The objective of social support group interaction is to strengthen their social support networks.
