Virtual reality glasses Beginning 2-3 minute before the start of the procedure, the patients will be watched (5 minutes) with an android mobile phone inserted into the Cardboard Super Flex Binoculars Glasses, with a music background, licensed product.

Before AVF cannulation, patients will be given a round, colored, medium-hard, high-quality silicone squeezable ball (the arm without vascular access will be used). In order to avoid implying that the procedure is inherently stressful, patients will be given the name squeeze ball when they are given information about the stress ball application. Patients will be instructed to continue squeezing and relaxing the stress ball (squeezing and relaxing once, counting from one to three) for 5 minutes before and throughout the AVF cannulation procedure. Patients will be instructed to focus their attention on the stress ball and focus on squeezing the stress ball.

Routine maintenance will be applied

The patients were asked to mark their level of pain during relaxation or activities on a 10 cm vertical or horizontal line. In addition, there were forms which were numbered from 1-10 or from 1-100. The number 0 is found at the beginning of the line, and the number 10 is located at the end of the line. A value of 0 shows that there is no pain, and the value 10 expresses unendurable pain. VAS is a common scale in the assessment of pain level. A patient is asked to mark the perceived pain on this line, and the marked point is measured in cm.

The Distress Thermometer is a scale developed by Roth et al. (1998) for determining psychological distress in cancer patients. The thermometer is a Likert-type scale with scores from 0 (no stress) to 10 (excessive stress). In a short and easy-tounderstand scale, patients can easily mark their distress levels in ranges indicated on the thermometer. The Turkish validity-reliability study of the Distress Thermometer for cancer patients was performed by Özalp et al. and the recommended cut-off score for the thermometer in this study was set at four and above.
