Group Positive Psychology-Based Program for Fear of Breast Cancer Recurrence

The goal of this clinical trial is to learn whether a group positive psychology-based educational program can reduce fear of cancer recurrence in women with a history of breast cancer who have completed primary treatment (surgery, chemotherapy, and radiotherapy). The main question it aims to answer is: Does an 8-week online positive psychology program reduce fear of cancer recurrence scores measured by the Fear of Cancer Recurrence Inventory (FCRI) compared to no intervention? Researchers will compare the intervention group (received 8 weeks of positive psychology training) to the control group (received no intervention during the study period) to see if the positive psychology program significantly reduces fear of cancer recurrence. Participants will: Complete online demographic and baseline Fear of Cancer Recurrence Inventory (FCRI) questionnaires (approximately 20 minutes) If assigned to the intervention group: Attend eight weekly 90-minute online positive psychology sessions based on Seligman's model via Skype Complete home exercises between sessions (e.g., recording three good things daily, writing a gratitude letter, practicing savoring techniques) Complete the FCRI questionnaire again immediately after the final intervention session. If assigned to the control group: Receive no intervention during the study period and complete the FCRI questionnaire at the same time points as the intervention group; offered the same positive psychology training two months after the study ends
