Result: There was a decrease in the value of anxiety in the group given guided imagery and music with an average value of 7.50 (p-value:0.000), whereas there was a tendency to increase the value of anxiety in the control group with an average value of 6.00 (p-value:0.083). There were significant differences in the mean value between the intervention groups (14.03) and the control group (24.97) with p-value 0.001.
