Objective: This study was planned to examine the effects of mindfulness-based yoga and

meditation practices on sleep problems, fatigue levels and quality of life in colorectal cancer


Method: The study was a quasi-experimental design with pre-post test applied, experimental

control group comparative design, and it consisted of 90 patients (45 people in the intervention

group, 45 people in the control group) between October 2021 and December 2021. In the study,

patient identification forms, Brief Fatigue Inventory (BYI), Piper Fatigue Inventory (PFI), Quality of Life (EORTC QLQ C-30), and Pittsburg Sleep Quality Index (PSQI) were used.

Results: While the BFI score evaluated in the study was 5.26±1.93 (0.67-10) in the intervention

group before the application, 5.83±1.98 (2-9) in the control group, it was 2.83±1.24 (0-5) in the

intervention group after the application, and 4.32±2.88 (0.33) in the control group. -8.34) was

found. While the PFI score was 4.02±1.91 (1.58-8.34) in the pre-application intervention group,

3.55±2.64 (0.33-8.34) in the control group, 2.6±1.82 (0-6.65) in the post-treatment intervention

group, 7.22±1.59 in the control group (4- 10) was found. In the EORTC QLQ C-30 (V-3.0)

measurement results, it was 12.7±4.23 (4-20) in the pre-application intervention group,

8.87±1.89 (6-14) in the control group, while 9.4±2.08 (6-14) in the post-application intervention

group. , was 7.22±1.59 (4-10) in the control group.

Conclusions: Our findings show that 12 weeks of cancer yoga and mindfulness-based meditation practice can effectively alleviate the sleep problems, fatigue, and subjective conditions that negatively affect the quality of life of colorectal cancer patients. It is recommended that future studies should investigate the long-term effects of yoga and meditation therapy on different cancer groups and that studies on colorectal cancer patients should be increased.
