In summary, the study found that the partner's FCR, health literacy and family resilience were closely related to the FCR in breast cancer patients. Therefore, healthcare workers can reduce the patient's FCR by reducing the FCR in spouses, improving patients' health literacy and family resilience in the future. In practical application, these findings hold significant implications for developing comprehensive care plans and interventions targeting FCR in breast cancer patients. By focusing on patients' partners and providing appropriate support and resources, healthcare professionals can promote patients' psychological well-being and overall health, leading to improved quality of life.
