Data Collection After obtaining the necessary institutional permissions, parents and children will be informed about the research through the "Informed Voluntary Consent Form" in the interview room 15 minutes before the blood draw. Research data will be collected by the researcher by face-to-face interview technique. A questionnaire including questions such as the age of the child, the time of the last blood draw, the parent's presence with the child will be applied to the parents. To ensure randomisation, children will be asked to choose one of the sealed envelopes. Then, the blood collection room will be passed to perform the procedure.

When the child to be taken to Experimental Group 1 sits in the patient's chair, the sound of the rain stick will be played 1 minute before the blood draw. The nurse will then begin to prepare the child for the blood draw. The tourniquet insertion procedure and the determination of the vein from which blood will be drawn from the antecubital region will be performed by the nurse. Blood collection will be taken from the antecubital region at once by the same nurse through the vacuum blood collection tube, and blood flow to the vacuum within 5 seconds will show that the procedure is successful. In the meantime, a pulse oximeter will be attached to the index finger of the hand on the other arm, where blood is not drawn, and the heart rate will be evaluated before the procedure and after the procedure. This process will take about 2-3 minutes and the children will listen to the sound of the rain stick throughout the process. After the procedure is over, the children will be taken out of the blood collection room and taken to the waiting area, and they will be asked to determine the severity of pain they feel during the procedure. WBFPS will be used to find out how much pain the child has during the blood draw, and ÇAS-D will be used to determine the anxiety state. Pain and anxiety level will be evaluated by the child, nurse, parent and researcher.

The Kaleidoscope will start to be watched 1 minute before the blood draw process, as the child, who will be taken into Experimental Group 2, sits in the patient's chair. The nurse will then begin to prepare the child for the blood draw. The tourniquet insertion procedure and the determination of the vein from which blood will be drawn from the antecubital region will be performed by the nurse. Blood collection will be taken from the antecubital region at once by the same nurse through the vacuum blood collection tube, and blood flow to the vacuum within 5 seconds will show that the procedure is successful. In the meantime, a pulse oximeter will be attached to the index finger of the hand on the other arm, where blood is not drawn, and the heart rate will be evaluated before the procedure and after the procedure. This process will take about 2-3 minutes, and children will be shown a kaleidoscope image throughout the process. After the procedure is over, the children will be taken out of the blood collection room and taken to the waiting area, and they will be asked to determine the severity of pain they feel during the procedure. WBFPS will be used to find out how much pain the child has during the blood draw, and ÇAS-D will be used to determine the anxiety state. Pain and anxiety level will be evaluated by the child, nurse, parent and researcher.

No interventional procedure will be applied to the children in the control group. The blood collection will be arranged in such a way that it is taken from the antecubital region in one go by the same nurse by means of a vacutainer. In the meantime, a pulse oximeter will be attached to the index finger of the hand on the other arm, where blood is not drawn, and the heart rate will be evaluated before the procedure and after the procedure. After the procedure is over, the children will be taken out of the blood collection room and taken to the waiting area. WBFPS will be used to find out how much pain the child has during the blood draw, and ÇAS-D will be used to determine the anxiety state. Pain and anxiety level will be evaluated by the child, nurse, parent and researcher. In both groups, parents will be provided with their children in the blood collection room during the procedure.
