Conclusions
The CPMs constructed in this study can be used as a prediction and evaluation tool for severe cases of clinical CC patients. Based on the CPMs, this study conducted a study on MBRS, which proved that MBRS can effectively improve the SOC, coping style, and CRF of CC patients, and the intervention effect was effective in the short term. The CPMs is significant for strengthening risk management, reducing or controlling the occurrence of severe CRF. It can strengthen the risk identification of severe CRF, and its independent risk factors provide scientific basis for CC patients to implement intervention measures.
