This randomized controlled study aims to evaluate the effect of a mindfulness-based psychoeducation program on hope, cognitive-emotional coping with cancer, quality of life, and psychological well-being in women diagnosed with gynecological cancer. Women receiving treatment for gynecological cancer will be randomly assigned to either an intervention group and a control group. The intervention group will participate in an 8-week mindfulness-based psychoeducation program delivered in small groups via online platforms under the guidance of the researcher. The program will include mindfulness practices such as breathing exercises, body scan, awareness exercises, and guided imagery techniques aimed at improving emotional coping and psychological well-being. The control group will receive usual care. Outcomes will be assessed at baseline, immediately after the intervention, and at 3- and 6-month follow-up assessments.

Gynecological cancers, including cancers of the cervix, ovary, uterus, vulva, vagina, and fallopian tubes, affect women's physical, psychological, and social well-being. Women diagnosed with cancer often experience emotional distress, uncertainty about the future, fear of recurrence, and difficulties coping with the disease and treatment process. These challenges may negatively affect psychological well-being, hope, coping abilities, and quality of life.

Mindfulness-based interventions have increasingly been used to support psychological adjustment and coping among individuals with chronic illnesses, including cancer. Mindfulness focuses on cultivating present-moment awareness in a nonjudgmental manner and helps individuals regulate emotions, reduce stress, and enhance adaptive coping strategies. Evidence from previous studies indicates that mindfulness-based psychoeducational interventions can improve psychological well-being, strengthen coping abilities, and increase hope and quality of life among cancer patients.

This randomized controlled trial aims to evaluate the effectiveness of a mindfulness-based psychoeducation program for women diagnosed with gynecological cancer. Eligible participants receiving inpatient or outpatient treatment will be randomly assigned to an intervention group or a control group. The intervention group will receive an eight-session mindfulness-based psychoeducation program delivered weekly in small groups consisting of approximately four to five participants. Sessions will be conducted online via secure videoconferencing platforms and will be guided by the researcher.

Data will be collected at four time points: baseline (before the intervention), immediately after the intervention, and at three-month and six-month follow-ups. The findings of this study are expected to contribute to the development of supportive psychosocial interventions aimed at improving hope, coping with cancer, quality of life, and psychological well-being among women with gynecological cancer.
