A longitudinal study on the changes in the self-efficacy of breast cancer patients during adjuvant chemotherapy.

The self-efficacy measures of patients with BC were significantly higher at both T2 and T3 than at T1 (p < 0.001). Religious beliefs and changes in self-efficacy showed a significant correlation (p = 0.04). These findings will facilitate timely interventional measures to improve self-efficacy in patients with maladaptive behaviours, alleviate psychological distress and reduce the risk of future disease recurrence.
