The Effect of Acceptance and Commitment Approach-Based Psychoeducation in Cancer Survivors

The study is planned to be conducted in a randomised controlled experimental design in accordance with CONSORT. The study is planned to be conducted between September 2025 and December 2026 at X Hospital with individuals who have completed cancer treatment. The randomisation list will be concealed from the participants, and each participant will be informed of which group they have been assigned to after being included in the study. The 'Stratified Randomisation' method will be used to determine which group participants will be assigned to, and participants will be included in the study based on their scores on the HAD scale. They will then be divided into experimental and control groups. To prevent study bias, the assignment of intervention and control groups will be conducted by an expert who has not participated in the study, with the aim of keeping the randomisation information confidential. The experimental group will consist of a total of 16 participants and will receive individual psychoeducation in an internet-based environment for 6 weeks, with each session lasting 30 minutes. No intervention will be made to the control group during the application period, and they will be placed on a waiting list. Participants who complete the psychoeducation will undergo follow-up measurements via an internet-based platform one month, six months, and one year after the psychoeducation, and their scores will be compared with those of the control group. The sample criteria include: having completed cancer treatment, having completed treatment for breast, gynaecological, colon or rectal cancer, having internet access, and being at risk for depression or anxiety in one or both of these sub-dimensions according to the Hospital Anxiety and Depression (HAD) scale. Exclusion criteria include receiving another psychosocial intervention, using psychiatric medication other than antidepressants, being in an advanced stage of cancer, having metastatic cancer, having recurrent cancer,
