 This study investigated the current status of self-efficacy and physical activity among Chinese colorectal cancer, CRC, patients and explored the relationship between them. The results showed that only 28.37% of CRC patients met the guideline recommendations for physical activity. Additionally, there was a significant positive correlation between the total self-efficacy score and the total physical activity score. These findings suggest that increasing self-efficacy may be beneficial for improving physical activity levels among CRC patients.
