After obtaining the necessary institutional permissions, parents and children who come to the blood collection room will be informed about the research through the "Informed Consent Form". The research data will be collected by the researcher using a face-to-face interview technique. Before the blood collection procedure, the children and their families who will be included in the kaleidoscope group, virtual reality group and control group will be informed about the research. The kaleidoscope will be used 5 minutes before the blood collection procedure as the child who will be included in the kaleidoscope group sits in the patient chair. The nurse will start preparing the child for the blood collection procedure at that time. The nurse will apply a tourniquet and determine the vein from the antecubital region to be taken from. The blood collection procedure will be taken from the antecubital region by the same nurse in one go using a vakuteynir (vacuum blood collection tube) and blood coming to the Vakuteynir within 5 seconds will indicate that the procedure was successful. This procedure will take approximately 2-3 minutes and the children will watch the kaleidoscope throughout the procedure. After the procedure is completed, the children will be taken out of the blood collection room and taken to the waiting area and the children will be asked to determine the level of pain they felt during the procedure. The child will assess how much fear the child experienced during the blood collection procedure and the level of anxiety.

The child who will be taken into the virtual reality group will be seated in the patient chair and virtual reality will be used 5 minutes before the blood collection procedure. The nurse will start preparing the child for the blood collection procedure at that time. The nurse will perform the tourniquet application and the determination of the vein from the antecubital region from which the blood will be taken. The blood collection procedure will be performed by the same nurse in one go from the antecubital region using a vakutainer (vacuum blood collection tube) and blood coming into the vakutainer within 5 seconds will indicate that the procedure was successful. This procedure will take approximately 2-3 minutes and the children will be shown virtual reality throughout the procedure. After the procedure is completed, the children will be taken out of the blood collection room and taken to the waiting area and the children will be asked to determine the level of pain they felt during the procedure. The child will assess how much fear the child experienced during the blood collection procedure and the level of anxiety they experienced. Children in the control group will not undergo any interventional procedures. Blood collection will be arranged to be taken from the antecubital region by the same nurse via a vacutainer. After the procedure is completed, children will be taken out of the blood collection room and taken to the waiting area. After being allowed to rest for 1-2 minutes, a questionnaire will be administered to the children. The child will evaluate how much fear the child has during the blood collection procedure and what their anxiety is. Children in the control group will not undergo any interventional procedures.
