This randomized controlled trial evaluates the effectiveness of a web-based psychoeducation program on psychological well-being and quality of life in breast cancer survivors who completed active treatment at least one year earlier.

Seventy-two women will be randomly assigned to either a 6-week online psychoeducation program plus standard care or standard care alone. The intervention consists of weekly 30-45 minute online sessions focusing on coping strategies, psychosocial adjustment, quality of life, and psychological well-being.

Primary outcomes include psychological well-being, fear of cancer recurrence, quality of life, and hopelessness, assessed at baseline, post-intervention, and 2-month follow-up.

This randomized controlled study investigates the effects of a structured web-based psychoeducation program on psychological outcomes in breast cancer survivors who have completed active treatment and are in remission for at least one year.

Eligible participants will be randomly allocated to an intervention group or a control group. The intervention group will receive a 6-week web-based psychoeducation program in addition to standard care, while the control group will receive standard care alone. The program is delivered through the online platform www.onkodestek.org and includes weekly live sessions conducted via Zoom, each lasting approximately 30-45 minutes.

The psychoeducation program addresses coping with breast cancer survivorship, psychosocial challenges, enhancement of psychological well-being, improvement of quality of life, and development of hope and meaning in life.

Psychological well-being, fear of cancer recurrence, quality of life, and hopelessness will be assessed at baseline, immediately after the intervention, and at 2-month follow-up using validated self-report measures. After study completion, participants in the control group will be granted access to the psychoeducation platform.

This study aims to assess whether web-based psychoeducation provides measurable psychological benefits for breast cancer survivors during the post-treatment survivorship period.

IPD sharing decision is pending completion of the doctoral thesis and institutional review of data sharing policies. The decision will consider participant privacy, ethical requirements, and journal publication guidelines.

This is an open-label study where masking is not feasible due to the nature of the intervention. Participants in the intervention group actively engage in weekly online psychoeducation sessions via Zoom and access the study website (www.onkodestek.org), while the control group receives standard care only. Both participants and researchers are aware of group allocation. The interactive nature of the psychoeducation program and direct participant-researcher contact during sessions make blinding impossible.
