The Intervention Group is informed about how to use the virtual glasses and is tested. One week after the first test, the patients in the Intervention Group visit a virtual museum on the theme of the patients' choice for an average of 20 minutes using virtual glasses for a total of five consecutive weeks. In the fifth virtual tour session, which is the third and final application session, measurements (Visual Analog Scale, Hirai Cancer Fatigue Scale and Beck Anxiety Scale) are made in both groups.

No virtual museum visit was applied to the control group. Scales were applied to individuals. For the control group, evaluations were made with scales three times in total.

Virtual Reality (VR) is a technology that creates simulated settings in which users can interact and experience as if they were physically there.Virtual Reality typically involves the use of a headset or glasses that display the virtual environment, as well as other input devices such as controllers or gloves that allow users to interact with the virtual world

The scale, originally named "Hirai Cancer Fatigue Scale", was developed by Kazue Hirai et al. in 2015 and consisted of 15 items . The scale is used to measure fatigue in cancer patients and has a 5-point Likert design. Each item on the scale is evaluated as 1 "not at all", 2 "very little", 3 "a little", 4 "a lot", and 5 "very much". It has 3 sub-dimensions (Physical-Mental, Activity-Related Sensitivity, and Cognitive Sensitivity). Items 1-6 on the scale constitute the Physical-Mental Sub-Dimension, items 7-12 constitute the Activity-Related Sensitivity Sub-Dimension, and items 12-15 constitute the Cognitive Sensitivity Sub-Dimension. The scale has no cut-off point. The minimum value of the scale is 15 and the maximum value is 75, with high scores indicating increased fatigue, while low scores indicating less fatigue. The validity and reliability study in our country was conducted by Mencel.

VAS, which evaluates the intensity of pain, is widely used in adults. The scale was developed by Price et al. as a scale consisting of a single 10 mm line that evaluates the intensity of pain. The two end definitions of the parameter to be evaluated are written at both ends of the line and the patient is asked to indicate where his/her condition is appropriate on this line by drawing a line, putting a dot, or pointing. For example, for pain, no pain is written at one end and very severe pain is written at the other end and the patient marks his/her current condition on this line. The length of the distance from the point where there is no pain to the point marked by the patient indicates the patient's pain. It has been shown that the line on which the test is applied is not affected by whether it is horizontal or vertical or by its length. The average of the values obtained for the patients is taken.
